Innovation-101: endless inspiration.

With the launching of the Learning Communities in 2011 Fall, at the New Jersey Institute of
Technology, Newark NJ (NJIT) we have introduced a systemic change1, for the entering fresh-
men.

As part of this initiative, the Department of Mechanical and Industrial Engineering (MIE)
introduced Reverse Engineering as part of the curriculum for the entering freshmen with Mechani-
cal Engineering as their chosen major. The MIE instructors have creatively and seamlessly blend-
ed Reverse Engineering with the existing Fundamentals of Engineering Design-101 (FED-101)
curriculum yielding successful learning outcomes. Freshmen in teams of 3 disassemble a live
product of their choice and recreate that using Creo Parametric three-dimensional solid modeling
software in accordance with industry proven procedures using 3D modelling. Freshmen experi-
ence the role of a Product Design Engineer in a corporation from ideation to product release.
Students learn to plan, prepare, perform and publish with a sense of accomplishment, the pride of
their accomplishment inspiring them endlessly2. Over the past 12 years the Reverse Engineering
program has grown year after year in its form and substance and has received the whole-hearted
acceptance, encouragement and support from the NJIT community.

After the inception of the Makerspace, apart from re-creating a virtual product most student
teams also indulge in adding an innovative extension to the existing product, using 3D printing
from Makerspace and demonstrate. The inspiration, which the freshmen experience through their
success and sense of accomplishment in their Reverse Engineering projects, is propelling them to
excel.

Innovation – inspiration – invention is an endless endeavor.

TOWER FAN

Yostina S. Fouad, Devin R. Genao & Shivam Sharma

The oscillating tower fan is powered by two motors that allow it to oscillate and blast air.
The motors are controlled by the user twisting a knob on the machine, which causes the fan to
blast air in the chosen direction. The user may control the fan speed and whether or not it oscil-
lates. The product contains two motors: one that blows air and one that oscillates the fan. If oscil-
lation is set, the product will blow cooling air in the direction the fan is facing while oscillating 60
degrees left and right from the neutral position. It is shaped like a cylinder to blast air into the
room as effectively as possible. By pushing air movement, the Tower Fan increases convective
cooling. The possible hazards of utilizing the fan include electrocution if it is wrongly plugged into
the wall, physical damage if the user's hair becomes entangled in the motors while whirling, or a
person trips over the power cable when plugged in. These hazards can be lessened when utilized
appropriately, although operator mistakes cannot be totally eliminated.

The Tower Fan we picked for our reverse engineering project is made up of 32 pieces and
three sub-assemblies. This Tower Fan is protected by US patent number US20120328430A1,
which was awarded in 2012. An earlier spiral tower fan design was manufactured in 2011.

HONEYWELL QUIETSET MINI TOWER TABLE FAN,
HTF210B

Patrick T. Kearney, Javier K.Quezada & Ethan G. Talanay

The Honeywell QuietSet Mini Tower Table Fan is a quiet compact oscillating table fan. It
features a tower that serves as a housing for the one fan located within. The base contains the
motor which oscillates the fan. On the exterior of the base the control panel can be found which
consists of several buttons. These buttons turn the fan on/off, activate the oscillation, control the
fan speed, and set an auto-off timer. At the rear of the fan there’s an outlet where a 12v external
power supply can be connected, to supply power to the fan. On the bottom of the fan are rubber
nubs which allow the fan to remain secured to the table while it oscillates. The product is designed
with the utmost convenience in mind. This is evident in many features such as its compact design,
built in carrying handle, and auto-off timer. It is clearly designed to be used at night due to the
different noise settings, but also can make a great daytime fan. The main assembly consists of 4
sub-assemblies: the fan assembly, the motor assembly, the pedestal assembly, and the switch
assembly. The fan assembly consists of the fan as well as the chassis for the fan. The motor
assembly features the motor, the crank, the pin, and the lever arm. The pedestal assembly con-
tains the base, the receptacle connector, the receptacle cover, the lubricating ring, the guide
bush, and the oscillation guide. The fan assembly consists of the chassis, the circuit board, the
gasket, the button caps and the cover. In total, the main assembly contains 28 unique parts with
several parts appearing multiple times throughout the assembled product.

MINI TOWER TABLE FAN

Christopher I.Gomez, Jer'Shawn R. Lewis & Jaiden J. Noeding

The product our group chose was the table fan. With fifteen unique and individual parts,
from the outer shell with a sleek and curved design, to the actual functional and operational piec-
es like the motor or the circuit board, all of them come together to make a fully operational table
fan. When taking the fan apart, the body/ shell of the fan split into two pieces, the posterior and
anterior portions. The anterior portion of the fan is equipped with wide vents, with functional but-
tons located at the bottom. The posterior portion of the model only has smaller intake vents. To-
gether the shell makes a cylindrical with a conical base. Looking inside, we first notice the fan
housing. The fan housing contains the fan blades itself and wiring to power the fan. Toward the
circular base of the fan, we can see a bigger motor that is held in place. The purpose of this motor
is to rate the fan on a swivel, allowing for a change in the airflow direction. Overall, there are 10
big components to the fan, this includes the front and back shells, the fan housing, the fan itself,
the base motor, the physical buttons of the fan, the button plate, the circuit board, the various
screws, and the power cord. These components are what we are going to focus on when design-
ing the model in Creo. Below is an image of the entire fan taken apart, as mentioned there are 10
major parts.

HONEYWELL HTF210B OSCILLATING PERSONAL FAN

Avishi Chaudhary, Crystal M. Onyeukwu & Jessica Pareja

Honeywell HTF210B Oscillating Personal Fan(Tower Fan) provides powerful personal
cooling with quiet operation and a slim, compact design. It uses two motors that oscillate 80 de-
grees at different speeds providing comfortable consistent airflow vertically. The air then moves
towards the air guide and finally heads towards the exit vent. The air blower pushes the air out-
side and distributes it evenly throughout the room. It has two automatic shut-off timers that can be
set for 2, 4, or 8 hours. Other features, such as fan speed and oscillation can be adjusted as well
as the four levels of sound of the fan that include sleep, white noise, refresh, and power cool. The
Timer and Oscillation features become active only when the fan is turned on. The 13 inches Tow-
er Fan only weights 2 lbs. which makes it extremely convenient to transport to any space and
improve airflow. It also has a steady 4.5-inch diameter stand base that resists falling or tripping
which makes it safer than any other traditional electric fans in the market. This unit uses 6 watts
on the highest setting, and it will use less power on lower settings which makes it ideal to save up
to 50% less energy than AC motors and 20% on energy bills when used with an air conditioner.

For the design engineering project, we have selected the Tower Fan which has 36 parts
and 5 sub-assemblies. The Vertical Fan has been patented in the US 7,118,323 B2 issued in
October 2006. A previous design of the Tower Fan was covered by a patent issued in 2011.

HONEYWELL TOWER FAN

Francis Lewis G. Flores, Joshua R. Haughton & Thomas A.Jackapino

Honeywell Quietset Tower Fan is an easy accommodation for any household or office space
which provides good cooling and heating. The fan brings in the customers needs of four different
speeds and sound adjustments to your own personal preferences. The tower fan’s design also
allows the airflow from any physical spacings in any spots. Honeywell designed the fan to run on
a two to eight hour timer to be set off which is utilized for the customer for a sleep accommoda-
tions or resting phase. Honeywell tower fans run high expectations from all previous works to
listen to the customers' expectations and what to improve for the future models. The Quietset
Tower fan goals were set to bring the customers flexibility in spaces for desktops and house
space. The fan also focused on reducing the amount of energy being consumed from the product
to reduce the customers energy consumption bill. The fan can save up to 50% of energy and
provide great cooling with many features and specifications to bring to the customers needs and
expectations for the future. .

HONEYWELL HTF210B QUIETSET PERSONAL TABLE FAN

Cavan J. Finnegan-Bendsen, Hector E. Rios & Jackson J. Royds

The Honeywell HTF210B QuietSet Personal Table Fan is a compact, easy-to-use personal
cooling fan. It stands at only 13 inches in height, and can be placed flat on top of a desk,
nightstand, and virtually anywhere with a flat surface. It weighs approximately 2 pounds, so it is
extremely portable if needed. The slim design of the mini tower fan helps in the reduction of plas-
tic production. The fan’s plastic vent design is also child and pet friendly, which protects them
from the fan blades. The fan comes with 4 different cooling modes: Sleep, White Noise, Refresh,
and Power Cool; each one cooler than the last. On top of this, it also keeps noise levels at a mini-
mum, even at the highest setting, when compared to other brands of fans. For users who enjoy
subtle “fan sounds” for falling asleep or just relaxing, the fan comes with varying levels of soft
sounds that change depending on the set power level. This fan helps produce airflow, whether it
be in the bedroom, living room, or office. It saves on energy consumption by 50% by using a DC
motor instead of an AC one. Replacing air conditioner use with this fan also cuts on energy usage
costs which not only benefits the user, but the environment as well. It also comes with an oscillat-
ing setting, when if selected, rotates for a full range of almost 180o. Another feature is the timer,
with a 2, 4, and 8-minute automatic shut-off timer options. .

TOWER FAN

Antonio R. Thomas, Richards C. Augustin-Lawson & Romel T. Russell

The Tower Fan is a mini fan that can be used in the bedroom or on your desk. To turn on
the device, press the power button located on the front panel. This small electric fan is pro-
grammed with an array of options that allow you to customize it to your liking. Pressing the fan
button will allow you to switch between four settings that gradually increase both air intensity and
sound productivity. As you press the button, the current setting will be indicated by a blue light.
The first setting is “sleep” which offers you a steady and silent stream of air. Next is the “white
noise” option, which gives you a slight increase in air intensity while also producing a faint sound
resembling white noise. Then there’s the “refresh” setting, which provides a moderate stream of
air. After that is the “power cool” setting, which produces a strong stream of air. In addition to the
four settings is a button toward the left of the front panel that turns on the oscillating function,
which causes the fan to rotate from left to right on its base. Aside from that there’s a button toward
the right side of the panel that allows you to set a timer with the options of two, four, or eight
hours. Once the specified time is up, the fan will turn off automatically.

The Tower Fan we have chosen for our reverse engineering project is sold by a company
called Honeywell. It consists of thirty parts and eight sub-assemblies.

TOWER FAN

Zafir Ali, Hugo T. Louriceira Tavares & Kade W. McDaniel

A Tower fan is a technological device to give a more powerful airflow. Tower fans work by
having air being propelled forward with the blades causing it to spin and push out cool air. These
are called impeller blades that move the air through the columns and out the vents. This tower fan
has a small footprint, meaning it occupies less space. The advantages of having a tower fan are
the design that lets it fit into small places, the weight that makes it affordable to carry around, and
the gentle cooling provided to those using it. The only disadvantage of the tower fan might be the
noise made while working, but this isn’t something intolerable that completely distracts the people
around. Many people use this kind of fan daily to have a cool room with fresh air offering the best
conditions to keep a chill environment where they can do all they need without the sensation of
uncomfortably. Companies invest a lot of money in this product to give their employees the best
atmosphere, which will motivate them to work harder, bringing benefits to the company.

The Tower fan we have chosen for our reverse engineering project has 38 parts and 8 sub-
assemblies. The tower fan we are using is a US patent number USD829319S1. The patent num-
ber for the first ever tower fan is US20040022631A1 and was issued in 2002.

TOWER FAN

Hussein Harb, Angelo F. Lucio Lucero & Joseph J. Maramangalam

The Honeywell Quiet set 13-inch oscillating tower fan is designed to cool down a room's
temperature while also not disturbing the room with a loud noise. Its silent nature allows it to be
used at night, ensuring that one's sleep will not be affected. The size of the fan being small also
gives it the advantage of being able to fit in small crevices and the option for easy transportability.
The Honeywell Quiet Set also features a carrying handle embedded on the top side of the fan.
The size also allows it to be placed on a desk and with its silent nature allows one to study in
peace. The fan has four built in modes which include high, medium, low, and sleep mode. All four
modes can be accessed manually through the fan buttons. The buttons located at the front of the
fan are all interconnected to a mother box which then sends signals to the mechanisms allowing
them to operate at an efficient pace. The fans light weight advantage gives one the ability to carry
it around to any place. Giving you the option to take it to any place where a cooling mechanism
may be needed. The Honeywell Quiet set 13-inch oscillating tower fan can also be chosen to
rotate in a side-to-side motion dispersing the cool air all around the area ensuring the coolest
vicinity possible.

By moving the air outward, the tower fan can circulate and cool the air in the room or space
it inhabits. It can cover 180 degrees of rotation thanks to its motor and gears. Its purpose is to
cool while keeping high energy efficiency.

The fan is designed and sold by Honeywell, also known for various home products. This fan
we chose for our reverse engineering project has 49 parts including 8 sub-assemblies.

TOWER FAN

Tamoor Faisal, Isa U. Khan & Patrick M. Polus

The oscillating tower fan is constructed of multiple assemblies to circulate air across an arc
region measuring various degrees. The fan takes, primarily, a cylindrical shape with multiple ex-
trusions across the body covers incorporating the grill. The optimized structure compactly houses
the fan blade, motor, and switch assembly rather than just standing as a tall tower. Consumers
are attracted to the aesthetic aspect of the fan which is the grill on both sides of the fan covers. It
is designed optimally to let maximum air flow out without compromising user safety when in the
proximity of the fan blades inside. The base assembly contains bearings along the sides to ac-
commodate the oscillating trajectory of the fan and complement the base of the covers. The ped-
estal (on top of the base) accommodates the motor and electrical components (circuit and wiring)
in its slots. Internally, the fan blade assembly is constructed of the fan blades and its cover to
house and constrain its motion around only one axis. The electrical component helps the motor
oscillate carrying the fan blades with it to eventually ventilate across an arc region externally.

Through the findings of reverse engineering, the Honeywell oscillating tower fan consists of
31 parts and 4 sub-assemblies. Walter Birdsell and David Feer hold the patent
US20040022631A1 for this type of oscillating tower fan where the fan blades rotate on a singular
axis.

TOWER FAN

Steven Abreu, Josiah Adorno & Jonathan Gurgus

The Tower Fan is a typical model of a rotating blade encapsulated by a chassis and exter-
nal body, operated by a motor for variable functionality in speed and mobility. The fan carries four
options for variable speeds alongside a rotational component responsible for the movement of the
base. Its distinct nature comes from its ability to act as white noise for the user rather than having
the specific purpose of outputting cooling air. Mundane/nuanced features include the fan's ability
to act on a timer, dimmed lighting on its LED display after lack of use (useful for power saving),
and the fan's use of wiring rather than a battery pack given its size. The fan, although functionally
sound, has a few flaws. It is unable to make a full 180° rotation using the base motor, which
makes it ineffective at cooling at long distances. Given that it emphasizes its ability to act as a fan
and white noise, it should make sense that it would operate with equal strength in both areas, but
this simply isn’t the case. The Tower Fan chosen for this project has 31 models and 9 subassem-
blies, alongside one final assembly displaying each assembly alongside the tool necessary for the
disassembly process. The patent number for the tower fan specifically is unspecified by Honey-
well, but there are several patent numbers for individual parts within the fan, with the release of
the patents being in 2015.

CAMERA FACE PENCIL SHARPENER

Kahyel Eaton & Brandon M. Lee

Be advised that it is merely a pencil sharpener, not a complete camera. It is advised that
you always bring it with you because it is lightweight and portable. It can be adjusted to accommo-
date the width of most pencils and features a handy bin for rapidly removing sharpening’s. It will
expose a little more graphite and grind a light concave shape. It really has the potential to produce
a more stable point for larger-diameter cores. It even features a knob on the rear to change the
sharpness of the pencil tip in addition to its opening being adjustable for pencils of different sizes.
You may look through the camera lens to observe how filled the drawer is to keep track of its
filling progress. This sharpener is available everywhere, including Walmart, Target, and Amazon,
so artists can locate dependable pencil sharpeners to generate flawlessly sharp pencils. The inner
cutter assembly is rotated as the user cranks the crank on the exterior of the pencil sharpener
because of the connection. The inner gear or sharpening blade is then turned since it is integrated
into the outer gear in the planetary gear train. As you turn the crank, the anvil also spins, causing
all of the pencil shavings that have gathered within to fall to the ground when it reaches the top of
its route. The inner mechanism spins while the outside gear shell stays stationary, allowing the
sharpening blade to also rotate. The cutter assembly's spin direction, which affects the direction in
which it is sharpened, may be changed by turning the crank in either direction.

The Kikkerland Camera Face Sharpener is covered by US patent number D669933, issued
in October 2012. This sharpener has 2 sub-assemblies and 7 different parts.

KIKKERLAND CAMERA PENCIL SHARPENER

Matthew De Oliveira, Francis J. Kelliher & Allen Zheng

The product we chose to design is the camera face pencil sharpener designed by Kikker-
land, a product design company that offers the world’s largest collection of ingenious items. This
tool only has a single, basic function of sharpening pencils and is seen commonly throughout
educational settings due to its effectiveness and its ease of use. The Kikkerland camera pencil
sharpener has a total of twenty six parts, and five sub-assemblies with a weight of about 10.6
ounces. This product has a dimension of 4.5 x 2.75 x 4 inches and has a model number of SC 12.

On the front surface of the faceplate, there is a button on the right hand side that is con-
nected to an inner mechanism on the inside of the faceplate. This button is what triggers the
mechanism and allows for a smooth insertion of the pencil, in which it then locks into place within
the sharpener. This allows the pencil to be secured while it’s being sharpened so the user won’t
have to worry about the pencil moving around or falling out.

This is a hand powered sharpener so no batteries or wires are needed. In order to sharpen
the pencil, the user has to turn the handle that’s on the back of the sharpener towards the right
since the handle is what rotates the cutter found within. Finally, the pencil shavings from sharpen-
ing the pencil gets dumped directly from the cutter and into the removable sliding tray on the bot-
tom half of the sharpener.

CAMERA FACED PENCIL SHARPENER

Helder Rebelo, Tyler R. Renninger & Marcus L. Shillingford

The Camera faced pencil sharpener is used as a portable way to sharpen a pencil, all while
the design makes it look like a camera. To get the pencil in, you have to press the little silver
button on the side, which opens up these arms at the entrance. After inserting the pencil all the
way in, you can let go of the button and the arms will secure the pencil in place. There’s a crank
on the back that allows you to sharpen the pencil. There’s a little knob on the back of the lever
that allows you to control how much you want the pencil to sharpen, as in if you want the point to
be stubby or tall. Underneath where you put the pencil in, there is a little tray that collects all the
shavings for you and gives an easy way to dispose of them. The top face of the sharpener, where
the pencil goes in, can be pulled out a little bit, held in place by a little metal tongue, and can snap
back to place with springs. The only purpose we discovered of this is for the maintenance of the
pencil sharpener. For the internal cutter to rotate, it is attached to the crank, when it turns, there is
a set of teeth that catch on a gear also attached to the crank, but stationary. When it turns, the
teeth catch on the gear causing the cutter assembly to rotate and sharpen the pencil. On the anvil
part, there is a tiny little spring held in place by a screw, and that keeps the cutter from turning the
wrong way.

CAMERA FACE PENCIL SHARPENER

Bryan S. Bartnick, Charly S. Rocano & Cassidy O.Stephen

A camera face pencil sharpener is a manual pencil sharpener. An aptly named gadget, a
camera face pencil sharpener gets its name from its striking camera-like appearance. To operate
the device, one presses a button located on the side of the sharpener, compressing and stretch-
ing a spring system (like a musician playing an accordion) to pull out the top part of the pencil
sharpener and lock an inserted pencil in place. Sharpen the pencil by turning a hand crank clock-
wise, rotating an epicyclic-planetary gear train cutter assembly. To release the pencil, one press-
es the same button again. Directly below the cutter assembly is a tray to collect pencil shavings,
which is removable for the disposal of the shavings by simply sliding out and in. Located at the
rear of the device is a knob that, when turned, adjusts pencil sharpness as desired. This specific
camera face pencil sharpener is manufactured and sold by a New York-based company called
Kikkerland. While the Kikkerland camera face pencil sharpener is a reliable, easy, and safe device
to use, it does come with some ergonomic dangers, including being cut by the rotational blade in
the cutter assembly or getting your finger stuck when the pencil sharpener’s face snaps shut. Both
are results of human error and cannot be eradicated.

A camera face pencil sharpener comprises of 26 models, three sub-assemblies, and one
main assembly. This product is covered by Chinese patent number CN105667157A, issued in
2017. An earlier design of a hand crank pencil sharpener is covered by U.S. patent number
US27287A, issued in 1860.

CAMERA FACE PENCIL SHARPENER

Michael C. Coburn, Daniel Lozano & Alexander Reinoso

The Camera Face Pencil Sharpener is a product designed by Kikkerland, a company who
specializes in designing kids’ toys. This pencil sharpener utilizes springs that stretch from their
equilibrium position to create enough tension to hold the pencil in place. It does this by a button
on the side of the product. As the button is pressed down, the springs are stretched and the holes
widen. Once the pencil is inserted simply let go of the button and the springs will snap back into
place, locking the pencil in the mechanism. Since the springs are so flexible, pencils of varying
sizes are able to fit inside the sharpening hole. This makes the Camera Face Pencil Sharpener an
especially handy addition to anyone’s office. There is a crank on the back of the pencil sharpener
that is connected to a cutter. Rotating the crank in the back rotates the gear train inside of the
pencil sharpener, which also rotates the cutter. This assembly grinds the pencil point until it is
properly sharpened. There is a bottom compartment where all the pencil shavings fall into. It is
easily detachable so when this compartment starts to get cluttered, cleaning will be a simple pro-
cess. Overall the Camera Face Pencil Sharpener is an incredibly versatile tool that can be used
by a wide range of individuals. It is simple to use and easy to maintain, and can be easily incorpo-
rated into a variety of workspaces.

The Camera Face Pencil Sharpener consists of 22 parts and 4 subassemblies. The patent
for this product is covered by US patent number D669933 issued in 2012. However, an earlier
design of this pencil sharpener is covered by US patent number 1974667 issued in 1934.

CAMERA FACE MECHANICAL PENCIL SHARPENER

Nicholas A. Barile, Greyson S. Cooney & Rafael L. Passaro Zegarra

Camera Face Pencil Sharpener (Pencil Sharpener) uses a gear crank to rotate a screw
blade to remove the material of the pencil sharpening it to a point. The face of the Pencil Sharpen-
er has a hole with a clamping mechanism designed to grab hold of the pencil upon inserting it.
This face is fixed to two springs that allow it to be pulled away from the body, once the pencil is
inserted and clamped the user spins the crank releasing the springs and forcing the pencil into the
screw blade. This allows the pencil to be sharpened without the user pushing the pencil in. The
removed material falls into a bottom drawer that can be removed and dumped when full. The
Pencil Sharpener also has a dial on the gear crank that allows the user to adjust the angle at
which the pencil is sharpened, making the pencil more or less dull. The product is made by the
company Kikkerland. This product makes the sharpening of pencils more seamless and the clean-
up much easier. There is very little risk of injury due to the blades being contained within the body
of the product however there is a risk for children with small fingers being able to access the
blades within. The nature of this product makes preventing this potential risk impossible.

The Pencil Sharpener we have chosen for our reverse engineering project has 30 parts and
3 sub-assemblies. This Pencil Sharpener is covered by the US patent D673611 issued in 2011.

CAMERA FACE PENCIL SHARPENER

Caden R. Hendrickson, Jeusten Jourdain & Ravidu S. Wijesundara Appuhamillage

The Camera Face Pencil Sharpener is a manual sharpener that is designed to look like a
camera. It works by the user turning a rear positioned handle around its axis which then sharpens
the pencil inserted through the other end. On the side of the product is a lever that when pushed
down, uses a spring mechanic to turn three internal parts which opens the compartment on the
front of the sharpener. This is the hole that the pencil is inserted into to be sharpened. On the
inside of the product is a corkscrew blade positioned diagonally on the inner side of where the
pencil is inserted that turns when the handle is turned which is what sharpens the pencil. The
blade spins around the pencil to ensure that all sides of the pencil are fully shaved. The shavings
from the pencil fall downwards into a container which can be easily removed from the body to be
emptied out. This allows for a quick disposal of the shavings. When the pencil is removed, the
compartment closes up again. The product as a whole is relatively simple and easy to under-
stand. For the most part the product is completely safe. However, there is a risk with removing the
shaving compartment and exposing the internal blade. The blade is not that sharp so this really
shouldn’t be an issue.

The Camera Face Pencil Sharpener is the product my group and I have chosen to con-
struct for our final project. It is composed of 28 individual smaller parts. The sharpener was pro-
duced by Kikkerland, is black and made of plastic and has 4” x 4.5” x 2.75” dimensions.

CAMERA FACE PENCIL SHARPENER

Marcelo Cardoso, Cristopher Mendez & Joseph Nathoo

The camera face sharpener was invented to functionally sharpen pencils to be efficient and
on point so it won’t break. The most important feature of this product is the internal parts that are
designed inside the sharpener. The first part of the sharpener is the cylindrical sharp metal object
that moves by turning the handle to go around the pencil to sharpen the utensil. It also attaches to
the pencil leaving the pencil nice and smooth to write with. The second feature that is important
on the camera face sharpener is its design with a bin at the bottom of the sharpener for the pencil

CAMERA FACE PENCIL SHARPENER

Aidan K. Dadiz, Joseph E, Madrigal & Noelle C. Pierce-Allen

The Camera Face Pencil Sharpener, invented by Takeshi Saito, provides an appealing
design to the consumer’s eye and an effective way to sharpen one’s pencil. The product is de-
signed like an old-fashioned camera with a lens and drawn dial at the bottom to closely resemble
the aspects of a real camera. It is composed of 3 sub-assemblies with 26 parts. The face plate
assembly is the top half of the sharpener. This sharpener includes a front plate with a camera
face on its upper half where No. 2 pencils can be sharpened without a mark. The cutter assembly
is the most significant part of the main assembly because it is how the pencil sharpener functions.
With this sharpener, the user will be able to achieve the perfect point and rely on its easy use. The
pencil insertion hole allows the user to smoothly as the knob is turned to sharpen for the pencil to
be in contact with the cutter and gears of the sharpener. Its clamp allows the pencil sharpener to
be held in place and sharpened efficiently while using the knob. The knob is located on its handle
which allows the user to adjust the sharpness of the pencil by turning it clockwise or clock-counter
wise altering the tightness of the cutter around the pencil when in use. The prop assembly is the
bottom half of the sharpener. On its lower half is a camera-like compartment with a lens playing
into the intentional design of the product. In this compartment holds the pencil shavings which can
be removed and disposed of easily. The compartment holds a specific capacity that saves the
number of trips taken to empty it.

Saito patented this product on July 28, 2011. Publication No. US2013/0147104

AFMAT PENCIL SHARPENER

Diana Cordero, Christina Pinheiro & Jesus D. Rivas

The AFMAT electrical pencil sharpener, Model S230, has a hole for the user to straightly
insert a 6mm to 8mm pencil into the mechanism. Once fully inserted, a cylindrical blade rotates
around the tip of the pencil to shave both the wood and the lead, thereby making it sharper. The
sharpener will not function if the pencil is pushed too far in. The blade is able to rotate around the
pencil due to the gears and motor that enable the device to function when plugged into an outlet
for power. There is a removable box underneath the pencil insertion point that allows the user to
clean the wood and lead shavings left over from sharpening the pencil. As a safety mechanism,
the pencil sharpener only works when the shavings box is inserted into the machine. There is a
switch located behind this box that allows the motor to function when inside. The AFMAT pencil
sharpener is an easy way to quickly and safely sharpen a pencil, as the user simply inserts their
pencil into the closed mechanism and the sharpener automatically does all the work for the user.
A danger that may pose a threat to the user is if they decide to insert objects into the sharpener
that are not a pencil. This danger can be avoided if the user is under supervised vision or under-
stands the potential dangers of using an electric pencil sharpener.

The AFMAT electric pencil sharpener has 24 parts and 2 sub-assemblies. This pencil
sharpener is protected under patent number 3134365A. The original inventor is Hori Takeo, and it
was issued in 1960. Another patent found for the electrical pencil sharpener is located under
number 3678975A and was established in 1969.

AFMAT PENCIL SHARPENER

Rjon D. Bucoy, Rylan T. Lech & Louis A. Scafidi

The pencil sharpener by AFMAT is electric, and convenient to use. The pencil sharpener
has a hole to stick a pencil into, as well as a clear plastic tray to collect the shavings that fall off of
the pencil. The housing is made from plastic to give a clean and durable finish. The hole in the
pencil sharpener contains two sensors, one in the back and one in the middle, that activate once
a pencil passes through them. The sensors then send an electrical signal to the motor assembly,
which spins the motor. The motor assembly consists of a motor, motor mount, and a copper coil.
The copper coil is what connects the assembly to the rest of the sharpener, as well as transmits
power to the motor itself. The motor is connected to a rod and gear attachment, which forms to-
gether with a much bigger gear wheel. Then when the motor spins, it turns the gear wheel which
spins the blade unit around the pencil for a clean even cut. The blade is cylindrical in shape with
spiral extrusions that are then sharpened at the ends.

The sharpener gives the user a quick and convenient solution to using a traditional hand
spun sharpener which would take longer in time. Not only that, but with the components being
made of metal, it allows for it to be durable and long lasting. As well as the housing being made of
plastic for rigidity and lightweights.

AFMAT ELECTRIC PENCIL SHARPENER

Islam Abuzid, Mohamed Hassan & Naithon Quizhpi

The product we decided to reverse engineer was the AFMAT electric pencil sharpener. This
sharpener consists of an assembly containing several parts. An AFMAT electric sharpener is
equipped to provide the best quality by being equipped with an upgraded motor to be capable of
sharpening over 10,000 times within 5 seconds. This electric sharpener allows you to insert a
pencil that measures 6-8 mm which will be automatically cut using a bigger and stronger Helical
blade made from alloy. The AFMAT electric sharpener allows for heavy duty use which makes it
great in commercial use or industrial use. This tool is effective in classrooms when it comes to
sharpening either pencils or different art pencils. Having a bigger helical blade increases the effi-
ciency that will be given out by always resulting in the sharpest point. This tool is convenient be-
cause it’s equipped with a small tray that can be easily removed to dispose of the shavings when
filled up. Also, it’s equipped with a safety mechanism that doesn’t sharpen when the shaving box
is not inserted correctly to prevent any injuries. The mechanism behind this electrical sharpener
consists of a big gear that rotates the rotator, and a small gear that rotates the big gear. Then the
motor will rotate the small gear which will cause the blades to begin cutting the pencil. Having an
AFMAT electric sharpener makes sharpening pencils very easy to use because it comes with a
120V cord, and the tool automatically sharpens the pencil. When using this tool, the pencil just
needs to be pushed in with some pressure and it will start sharpening.

AFMAT PENCIL SHARPENER

Anes M. Abdrabou, Mohammad T. Imleh & Joshua Kruk

The AFMAT Pencil Sharpener sharpens both pencils and colored pencils efficiently. After
inserting the pencil inside of the frontal hole of the pencil sharpener, the pencil shortens as it is
carved to have a sharp point. The machine does this through the spinning of the metal cutter
inside of it via electric motor, speedily rotating a cutter assembly to shave the pencil down with
little effort. As the pencil is sharpened, wood shavings and other pieces that have been shaved off
during the sharpening process are collected in the detachable debris tray at the bottom of the
pencil sharpener. This machine can be utilized after simply plugging it into a 120V outlet. The
AFMAT Pencil Sharpener (Model 19), is produced by the company SHENZHEN ZEMIAO NET-
WORK TECHNOLOGY CO., LTD. The AFMAT Pencil Sharpener is an essential for anyone in
need of an excellent, easy-to-use, pencil sharpener. This electric pencil sharpener can sharpen
over 10000 times in only 3 to 5 quick seconds, and a sharp point to a pencil will be produced
every time. However, it must be advised to not push the pencil too hard into the hole when sharp-
ening, or it will make an unintentional humming noise and will not sharpen pencils as a result due
to the clogging of internal machinery production with wood and lead shavings. This complication is

The AFMAT Pencil Sharpener we have chosen for our reverse engineering project has 24
parts and 2 sub-assemblies.

AFMAT PENCIL SHARPENER

Zain D. Alomari, Cristopher J. Salazar & Daniel Vazquez

The AFMAT pencil sharpener is an electric pencil sharpener powerful enough to sharpen
your pencils or colored pencils to a perfect and durable point in only three to five seconds with
ease. It is an automatic pencil sharpener with a heavy-duty helical blade. Do not push the pencil
too hard when sharpening or it can damage the blade. This pencil sharpener has no issues after
sharpening multiple pencils at a time. It is faster, more durable and powerful than any other heli-
cal blade sharpeners due to its bigger and stronger helical blade. Perfect gift for anyone who
needs a heavy-duty pencil sharpener. This pencil sharpener will start sharpening automatically
when you insert a pencil. Take out the pencil when the motor sound changes and the
resistance of sharpening decreases. Great for graphite and colored pencils. Please note that it is
not recommended to sharpen sketch pencils or soft carbon pencils as it may cause jams in the
blade. High efficiency, fast speed and heavy use make it a commercial pencil sharpener. This
pencil sharpener has two safety features: stop working when the shavings box is removed or not
close tightly and stop sharpening when it is overheating. Nonskid feet at the bottom make it more
stable when sharpening. The AFMAT electric pencil sharpener comes with a wall plug, which is
easy to use.

AFMAT ELECTRIC PENCIL SHARPENER

Justin Chou, Richart Ng & Joseph M.Stoveken

The AFMAT Electric Pencil Sharpener, or Model 19, has a cutter connected to a motor
inside of a casing. The cutter spins while in contact with a pencil in order to shave off layers of
wood and the graphite clay mixture in order to create a point the user can write with effectively.
When a pencil is placed inside the Model 19, a switch causes the motor to receive power and
spins the cutter and thus the pencil is sharpened. The Model 19 makes sharpening your pencil
easier by completely automating the sharpening process with the use of motors and gears. The
Model 19 allows the user to sharpen efficiently and in relative comfort compared to mechanical,
hand-powered sharpeners. Unless the Model 19 is damaged in a way that exposes a wire or
moving parts within the container and a person touches the part while the device is running,
there is no reasonable danger associated with the Model 19. This danger is caused by human
error and cannot be rectified by modifications to the device by the company.

The Pencil Sharpener we have chosen for our reverse engineering project has 27 different
parts and 3 sub-assemblies. This Pencil Sharpener is related to a device under the US patent
number 3,678,975 issued in 1970. Since then the patent has been innovated upon many times
over. For instance, the newest model has a switch connected to the Debris Tray to reduce the
risk of having direct access to the Cutter.

ELECTRIC PENCIL SHARPENER

Nicholas A. Garcia, Franco Montes & John Wszolek

The Electric Pencil Sharpener sharpens any type of pencil and color. Even the thinnest lead
pencils used by artists can be sharpened comfortably with this. With an upgraded, more potent
motor, this electric pencil sharpener can easily sharpen over 10,000 times in only 3-5 seconds.
This product will sharpen a beautiful pencil point each time. It’s highly effective for graphite and
colored pencils, such as Prismacolor Premiers, Derwent, Verithins, Faber-castell, and Koh-I-Noor
Progresso (all are different types of colored pencils). One caution people should know about this
product is they don’t recommend sharpening soft-core pencils as it may cause jams in the blade.
While sharpening the pencil, one shouldn’t push too hard when sharpening, as it will make a
“hum” noise and not sharpen properly. It’s faster, more durable, and more effective than the aver-
age sharpener at the convenience store. AFMAT 10,000 times sharpening is due to the upgraded
alloy material. The helical blades sharpen pencils better due to their bigger and stronger helical
blade motor. It has two safety features: it stops working when the shavings box is removed or is
not closed tightly and stops sharpening when it overheats. Another feature is the non-skid feet at
the bottom to make it more stable to sharpen. This model is particularly useful for everyday use in
classrooms and other office facilities.

The AFMAT Electric Pencil Sharpener we have chosen for our project has 27 parts
including around 4 sub-assemblies. In addition, the electric pencil sharpener is covered by a
patent number of 3,134,365 from Hori Takeo issued in Japan in 1964

AFMAT PENCIL SHARPENER

Patryk Adamczyk, Michael A. Jones & Nicholas B. Levchook

This invention features a fully automatic pencil sharpener, which has a base, on which the sharp-
ener is fixed. The Afmat pencil sharpener provides a container to collect pencil shavings on the
bottom of it. On one side of the pencil sharpener there is a pen entering mechanism which makes
use of a rotating blade assembly inside that sharpens the pencil. It does this by using the motor
on the inside which activates when the sharpener is plugged in. This product is silent unless being
used. The Afmat pencil sharpener is sold by the company AFMAT, which is trademarked by
SHENZHEN ZEMIAO NETWORK TECHNOLOGY CO., LTD. The pencil sharpener makes the
sharpening process automatic. The only manual work needed is to pick up the pencil and place it
into the entry hole. Thus, making the process nearly effortless. It is a very simple machine, with a
sleek and simple outer design. The sharper is perfectly safe when used properly, the only poten-
tial danger may come if the pencil sharpener is tampered with, or used incorrectly. This danger is
caused by human error and generally cannot be erased.
The Afmat pencil sharpener we have selected for our final innovation project has 24 parts and 2
sub-assemblies. The Afmat pencil sharpener is covered. By US patent No. 2,615,426 Fryer Oct.
28, 1952 an earlier ensign was patent by U.S patent No 1,943,861 Myers Nov. 12, 1912.

AFMAT MODEL 19 ELECTRIC PENCIL SHARPENER

James M. Mauriello & Layth Younes
The AFMAT Model 19 Electric Pencil Sharpener is a lightweight, heavy-duty electric pencil
sharpener marketed by AFMAT, a leading office supply company. This product can be found in
any office or classroom where frequent use of pencils is required. In addition to standard #2
pencils, this product can also sharpen a variety of colored pencils with sketch and soft carbon
pencils being the exception.
One of the features of the Model 19 is the helical blade, or cutter, assembly. It is larger
than the competitors and constructed of a more durable alloy as opposed to plastic. This design
doubles the lifetime of the blade from 3000 sharpening to 6000. In addition to the improved dura-
bility, the Model 19 sharpens a pencil to a fine point in 3-5 seconds and changes sound when
sharpening is complete. There is a large shavings box near at the bottom of the pencil sharpener
that collects the pencil shavings. On the bottom base of the Model 19, there are four non-skip
footpads which provides stability while the pencil is being sharpened.
In addition to durability and speed, the Model 19 boasts two separate safety features. First,
the Model 19 will not function if the shavings tray is removed or is not closed tightly. Second, it
will not function if it begins to overheat. These two features prevent accidental injury from the
blade and preventing fire from overheating. The footpads on the bottom of the Model 19 also aid
in preventing it from sliding off an edge. Finally, there is a standard wall plug that allows the
Model 19 to be powered by a standard electrical outlet.

DESIGNING AND MANUFACTURING
A METAL SKATEBOARD

Oxford R. Bayley, Braeden J. Goebbert & Kimberly A. Harding

The purpose of our project was to design and manufacture a metal skateboard. A metal
skateboard has the same purpose as a traditional skateboard, except the deck is made of metal
instead of wood. Our group used Creo parametric to design the deck of the skateboard. A Creo
assembly was then made with wheels, trucks, and bearings to create a model of the final skate-
board. Our Creo file was converted to a DXF file for manufacturing the deck using the waterjet.
The prototype was made of steel to ensure rigidity for the board. The steel plate was ¼ inch thick
and was more than capable of withstanding the weight force of the average individual. However,
the steel was dense and heavy, which is why we altered our original Creo design to have cutouts
in the deck to reduce the weight by 46% while retaining strength. Our final weight came out to 7
lbs. while the average wooden deck is 5 lbs. Our metal deck is slightly heavier but is very strong
and durable compared to the average wooden deck. After using the water jets to manufacture the
deck, we assembled the wheels, trucks, and bearings to the deck of the skateboard to create the
final prototype. Testing was done on the final prototype to determine the tightness of the trucks to
improve the control of turning the board.

DESIGN AND FABRICATION OF
A SKATEBOARD USING A MOLD

Gabriel Correa, Raymond Liu & Henry Yao

The purpose of this project is to design and manufacture a mold to create a skateboard. A
skateboard is a board, that someone stands on, with wheels, to either be used as a form of trans-
portation or to perform tricks on. The skateboard itself consists of three main part groups – the
deck, the trucks, and the wheels. Since the project is to create a deck using a mold, we utilized
Creo Parametric for our design. The mold was designed to be simple, lightweight, and cost-
effective to keep the overall price of the skateboard down. The manufacturing process began with
uploading a .stl file up to fusion and using fusion to create the mold surfaces. After the surfaces
were created the file was sent to an Atlas CNC Table Router to create the mold out of a special
type of foam. Once the mold was created, the wooden planks would be pressed onto the mold
inside a vacuum-sealed bag, so a top mold was not required at all. The pressure created inside
the bag allowed the thin planks of wood to fall into shape and become one piece (with an adhe-
sive) gaining strength while maintaining light weight. Finally, we utilized off-the-shelf parts, like
trucks, wheels, and grip tape to finish the skateboard.

DESIGNING, MANUFACTURING, AND TESTING
A METAL SKATEBOARD

Khalil I. Amro, Martin A. Soliman & Daniel Matthews Wensuslaus

The purpose of this project was to design and manufacture a metal skateboard. The design
features an aluminum deck attached to a set of four wheels to transport a rider. Due to its portabil-
ity and ability to transport a rider across a variety of surfaces, the skateboard is a convenient
source of efficient transportation. After developing an initial sketch of the design of the skateboard
based on its requirements, the components of the project were designed by utilizing Creo Para-
metric. After completion, simulations and analyses were completed on the program in order to
ensure the strength, flex, and weight of the assembly was suitable. The CAD models that we
developed were then converted to .drx files and the aluminum sheet (Al6061) was shaped into our
design by the waterjet. In order to decrease the weight of the board, we altered the design and cut
unnecessary parts of the deck, but utilized computations to ensure that the structural integrity of
the board would not be compromised. We drilled holes in our deck to attach the truck, and added
countersunk holes to allow the screws to be flush with the deck. After adding finishing touches as
well as grip tape, we tested the performance and added tweaks to optimize its performance.

DESIGN, FABRICATION, AND TESTING OF
A METAL SKATEBOARD

Peter Z. Varga

The purpose of this project is to make a functional metal longboard that is both durable and
not too heavy. All manufactured components were designed in Creo, those being the board and
the supporting sheet, however, the trucks and wheels were bought off the shelf but also recreated
in Creo for the final assembly. The shape and length picked for the board were done so with sta-
bility and smoothness in mind, the longer the board the more stable it is, and thus would be easier
for people new to skateboarding to use, however, this made it heavier as more material was
needed. The metal was cut using the water jet in the Makerspace using the models that were
previously made in Creo and then drilled for screws. The main board is made of 2 layers of ⅛”
aluminum polycarbonate composite that is about 30 inches in length and 9.5 inches in width. On
its own ⅛” aluminum composite is not strong enough to support the weight of a person but it was
used to save weight and then it was reinforced with an ⅛” aluminum plate for stiffness and
strength. This aluminum plate does not span the whole length of the board but only between the
trucks in order to save weight and to save material as the tips of the board are short enough
where the aluminum composite has enough strength to support the minor loads that would be
applied to them.

DESIGNING, MANUFACTURING, AND TESTING
A WOODEN DROP-THROUGH SKATEBOARD

Youssef B. Salem & Brian D. Solano
The drop-through skateboard is designed for a smooth and stylish ride. The premise of the
skateboard is no matter what road you're on, it will be smooth and brings you from point A to point
B with ease. We used Creo Parametric to design the skateboard deck and rough designs of the
dimensions of the off-shelf trucks and wheels and another software we used was Fusion 360 to
create the mold. The material used for the mold was rigid foam board and for the deck itself, we
used a sheet of ⅛ Baltic birch wood that was cut into 4 pieces in order to make our board and
glue them together which would then be vacuumed into our mold to create the curves needed.
The manufacturing processes we used to create our board were the Atlas CNC Table Router in
order to cut out the shape of our mold on the rigid foam board, the cabinet saw in order to cut out
the large sheet of wood into smaller pieces, we then outlined a sketch of the board on wood and
used the band saw to cut out the shape then we used the combination sander and oscillating
spindle sander to smooth out the edges. Finally, we used the drill press in order to place our
trucks on the nose and tail of the board and assembled all the parts together, and tested the per-
formance. It has come out as it was expected. The wheels make it easy to pass through bumps,
and its flexible body makes the ride very smooth for the rider.

DESIGNING, MANUFACTURING, AND TESTING
PROSTHETIC GRIPPER

Mufti S. Ahmed & Farhan Sufian

The purpose of this project was to design and build a prosthetic gripper. The prosthetic
gripper allows the user to grab and hold onto objects with ease. The prosthetic is designed to
minimize the amount of effort needed to activate the arm by being activated with the flip of a
switch. Creo Parametric was used to design the 3D CAD models and assemblies based on the
conceptual designs. The gripper was designed for convenience, ease of use, and durability. We
used Creo assemblies to analyze interferences and assess the viability of our design. We used
additive manufacturing techniques. We exported the CAD models into CURA and prepared them
to print on the Ultimaker 3 and Ultimaker S5 3D printers. For the material of the parts we mainly
used PLA (Polylactic acid) and TPU (Thermoplastic Polyurethane) filaments for their lightweight
and flexibility. For the assembly, we used fishing lines for their strength and tension springs to
allow the mechanism to open and close. For the motorized pulling action, a 15 rpm, 12V DC mo-
tor is activated by a simple switch. 5m hex screws were also used to fasten it all together. We
then assembled and modified our design as needed to increase efficiency.

DESIGNING, MANUFACTURING, AND TESTING
A CRUISER SKATEBOARD

Michelle Arce & Keyla M. Mejia

The purpose of this project was to design and manufacture a functioning skateboard, spe-
cifically a cruiser. A cruiser is a type of skateboard designed for traveling locally on level pave-
ment. Our skateboard was designed with minimal concave and a kicktail shape with the intention
of being beginner friendly. We started with Creo Parametric to design a 3D CAD model and as-
sembly of the cruiser prototypes. Creo was also used to design a 3D CAD model of the skate-
board mold that would be used to shape the wooden deck. Fusion 360 was then used in order to
accurately bring the 3D model of the skateboard mold into physical form. Its G-code was used to
instruct a CNC table router to accurately cut the 3D mold design out of XPS foam. We then used
Solidworks in order to bring our 3D skateboard model into 2D form, so a template could be laser
cut for reference when cutting the wooden veneers into the shape of the skateboard deck. The
same process was additionally used to laser cut the specific shape of the skateboard onto the grip
tape to save the effort of cutting it physically. For the skateboard to be sturdy and long-lasting, we
will use ⅛ in. Baltic birch plywood and cut it into 4 pieces to glue on top of each other, so the final
skateboard deck would be about ½ in. The skateboard deck is formed through a high-pressure
vacuum sealing process that will press the wood into the shape of the foam mold. This would
conclude the assembly process and the prototype would be ready for testing.

DESIGNING AND MANUFACTURING
THREE ARTHRITIS AIDS

Christian R. Alvarez, Jake G. Mulrenan & Adam N. Wiuff

The purpose of the project was to design and build three arthritis aids to help people with
physical ailments complete daily tasks more easily. Our three arthritis aids were a thumb support
device, a toe spreader, and our own product we call the Phoner. The thumb support is a simple
plastic brace that wraps around the user's thumb to restrict movement so that they do not feel so
much pain when using their hand. The toe spreader is a small device used to space out the toes
of the user so that they can feel relief from being stuck inside shoes all day and increase joint
mobility. The Phoner is a device to hold the user’s ID in a case that is mounted to the back of the
phone. The mechanism uses a simple lever to push an inner channel that houses the id in the
outer case. The device is used so that the user has easy access to their card without having to
reach in and out of their pocket or wallet to access their card. It is also more than a simple phone
wallet because it allows the user to utilize the magnet strip on the card while it is in the Phoner.
The Phoner was designed on Creo while the thumb support and the toe spreader were designed
on meshmixer. The Phoner was assembled with all of its smaller parts and simulated on Creo. All
three were manufactured using additive manufacturing through cura and the Ultimaker 3 3D print-
ers. All three products were made out of PLA. The thumb support and the toe spreader were
tested for size and then reprinted and the Phoner was tested for functionality, tested, redesigned,
and reprinted until our model worked successfully.

DESIGNING, MANUFACTURING, AND TESTING
A WOODEN “NICKEL BOARD”

Juan C. Henriquez & Jaden Perez

The purpose of this project was to design and build a wooden skateboard. The skateboard
would be designed to effectively function in a variety of environments while maximizing the com-
fort of the user. To make this skateboard we first had to make our own design on Creo. Once we
came up with a model, the mold was made using the “Atlas CNC router table”. Next, wood sheets
were used with the mold to get the shape of our mold. After letting it sit and dry for 12 hours we
will take the rectangular board we have made with our mold and cut it into the shape we want.
Once we get the shape we want we then make the holes for the trunks, so we can add the wheels
and trunks. Then the skateboard will be ready to test. We will make sure that it is functional, light,
and could hold a capacity of at least 250lb .

ARTHRITIS AID

Yasser O. Aglaguel, Matthew Ibrahim & Mark Nyevgen

The purpose of our project is to provide arthritis patients the ability to play indoor activities
including pool, ping pong, and cards. This is done by designing products that reduce the need to
use grip strength and reduce the user’s dependence on finger dexterity since these attributes are
negatively affected by arthritis. Our three designs include a pool cue grip, a table tennis glove,
and a playing card holder. The design of the pool cue grip creates a handle around the cue with a
large diameter, which is easier for arthritis patients to grip; in addition, the grip at the front re-
moves the need for players to use their fingers to hold the tip of the pool cue. The table tennis
glove was designed such that the user does not need to tightly grip a handle to control the paddle
faces, instead, they can simply insert their hand into an opening and move their arm to maneuver
the paddle faces. The playing card holder was designed for human hands that have trouble grip-
ping to make it easier. These parts were made using Creo Parametric. The models were then
prepared for 3D printing with CURA. Each component of the models was made with various mate-
rials such as PETG, PLA, and TPU. The components were then combined using heat inserts and
glue. Then they were tested to see if they are comfortable and worked as intended

DESIGN AND MANUFACTURING OF A
3D-PRINTED HAND REHABILITATION DEVICE FOR

STROKE PATIENTS

Anmol S. Doss, Omar A. Elfar & Avanish G. Kulkarni

The purpose of this project was to design a 3D-printed rehabilitation device to help stroke
patients regain finger mobility. The product uses the tendonitis grasp technique and works by
connecting the wrist joint to the motion of the user’s fingers in order to allow them to open and
close their fingers by twisting their wrist. Inspiration was taken from other designs found online for
stroke hand rehabilitation devices, and the emphasis in our project was placed on design for sim-
plicity of manufacturing, in order to address some of the limitations and problems with existing
designs with regard to manufacturability. The design was completed using Creo Parametric and
consisted of 5 basic components: the forearm portion, the palm portion, the finger holder, and two
connector rods. The model was assembled in Creo and the project was manufactured using Ulti-
maker FDM printers with PLA filament for low cost combined with a high degree of rigidity, and the
ability to use the thermoplastic properties to quickly secure the parts together. Heated inserts and
screws were used to secure the different components and joints together and bearings were uti-
lized to ensure smooth and easy movement of the joints. Velcro straps were used to secure the
device to the arms.

IMPROVING AND MANUFACTURING
THE WOLVERINE ARTHRITIS AID

Samantha J. Montalbine, Rachna Pandit & Cynthia L. Vargas

The purpose of this project was to design an assisting device to help people with Arthritis
and those that struggle with mobility. Arthritis is unique to each person, but the Wolverine is a
gadget made to specifically help patients who cannot maneuver their hands as they would like. It’s
worn on the back of the hand, and there are threads attached to each component that work to-
gether to eventually help lift your finger; helping you to move your joints and bend your fingers.
Creo Parametric was used to design the 3D CAD models based on the conceptual designs. The
flanges, forearm, lever, finger holds and handpiece were designed for strength and mobility under
any weight and size. The bolts are designed to fit some holes created in the models and piece
them together. Creo Simulate was used to analyze the performance of the parts altogether and
whether they would fit and function properly in the measurements they were designed in. 3D
printers, soldering irons, and other technology were used in the design and development process
to build the prototypes. The CAD models were processed to be 3D printed using Ultimaker CURA.
The prototypes were printed mainly using Ultimaker-3, but Ultimaker-5 was used to print one of
the parts. The material used was PLA (Polylactic Acid) with a 35% Infill Percentage for additional
strength and durability. After each part was printed, the individual parts were assessed and their
dimensions were compared to each other and the non-3D-printed components. Based on the
results, the CAD models were edited, re-sliced, and re-printed to improve the assembly and over-
all performance.

DESIGNING, MANUFACTURING, AND TESTING
A 3D-PRINTED ASSISTED DEVICES

Andrew M. Ascuas & Kyle M. Garwood

The purpose of this project was to design and build a 3D-printed stethoscope. A stetho-
scope is mostly used by doctors to hear the heartbeat and to make sure there are no abnormali-
ties happening with the patient. Stethoscopes online available to purchase are expensive, our
goal is to make a cost-effective stethoscope that would perform the same way as a standard-
issue stethoscope. Initial designs were developed based on making it functional. Creo Parametric
was used to design the 3D CAD models and assemblies based on designs. The stethoscope was
built to be comfortable and make sure it’s able to hear a heartbeat. Purchasing of other materials
was required such as hose piping, large earbuds, and a document report cover (cut out to be
used for the diaphragm). The CAD models were processed for 3D printing using CURA and the
prototypes were printed using Ultimaker-3, the material used is PETG (Polyethylene terephthalate
-glycol) for additional strength. The stethoscope is still in its manufacturing phase. It is still not fully
built as there have been some minor setbacks. .

DESIGN, MANUFACTURING, AND TESTING OF
MEDICAL ASSISTING DEVICES

Teja Bavanari, Lucas D. Perez & Artim Reci

The purpose of our project was to create devices that would assist people with medical
ailments like arthritis, joint problems, and limited hand use. We designed a device in order to
reduce strain on joints while using a computer mouse along with multiple devices to facilitate the
easier opening of containers like jars, bottles, and cans. We also redesigned a device in order for
people with the use of only one hand to be able to use normal video game controllers without
major modification. The software that we have used for these devices is Creo Parametric. This
software has been very helpful in helping us visualize where and how the parts fit in with each
other. They allow us to edit all the parts easily while we are virtually assembling the device. Creo
has also allowed us to optimize the design for 3D printing. We have also used CURA which is the
software that we used to 3D print all of our designs. This helps us visualize and see how the mod-
el looks on a print bed. It also lets us modify the settings for 3D printing to our liking depending on
what we want it to be. After the designing process in Creo Parametric and CURA, the manufactur-
ing began using our personal 3D printers and printers from the NJIT Makerspace (Ultimaker-3)
with materials such as PETG, PLA, and TPU. After the initial prints, testing made it easier to un-
derstand any modification that must’ve been done on the models. Based on any of these modifi-
cations, the parts were reprinted and tested again in order to achieve their initial goal.

DESIGNING, MANUFACTURING, AND TESTING
AN AUTOMATIC WASHCLOTH WRINGER

Daniel J. Benson & Evan B. Casaleggio

The purpose of this project was to design and build an automatic washcloth wringer. Due to
their arthritis, many people are unable to perform simple tasks we often take for granted, such as
wringing out a washcloth. Our product aims to solve this problem. By gripping the washcloth with
two clamps, and twisting it with the use of a motor on one side, we’re able to easily, effectively,
and comfortably wring out the water contents with the push of a button. Creo Parametric was
used to design the 3D CAD models and assemblies based on the conceptual designs. The two
base arms that stand on each side were designed for strength and stability while the motor spins
and the wet washcloth weighs on the build. Additive manufacturing technology was used in the
design and development process to build the prototypes. The CAD models were processed for 3D
printing using CURA, and the prototypes were printed using Ultimaker-3, the material used is PLA
(polylactic acid). Following this, the automatic washcloth wringer was assembled and tested for
performance. Based on the results of the preliminary testing, the design was slimmed down and
additionally modified to enhance and optimize the overall quality.

DESIGN, MANUFACTURING, AND TESTING OF
A WOODEN SKATEBOARD

Vincent J. DiMeglio, Nikita Gatilov & Lukas Wilowski

The purpose of this project is to design and manufacture a skateboard that can be used for
transportation and entertainment as well as adhere to quality standards. The skateboard is com-
posed of 7 maple veneers glued together by wood glue and pressed into shape by a mold. The
mold is made of hard styrofoam glued to a wooden base and shaped in accordance with dimen-
sions outlined in conceptual design. Creo Parametric was used to design the 3D-models and
assemblies for the proposed designs of the skateboard. The skateboard design was centered
around strength and rigidity during use; making sure that the structure was capable of holding a
person riding it while providing the required stability to make the maneuvering process possible.
Certain manufacturing processes were used throughout the Makerspace to create the prototypes,
including: structural bandsaw, drill press and the sanding process. After creating the prototype, we
finalized our skateboard based on the results from the prototype tests, administering improved
models and features to create our final prototype ready for presentation.

THE SKETCHING, MODELING, AND MANUFACTURING OF
THE ARTHRITIS GRASPER ARM

Qasem Alkhatib, Tristan A. DePrizio & Jonathan W. Hopkins

The purpose of this project was to design a functional and practical motorized claw for
persons suffering from Arthritis or other ailments of the hand and arm, that would prevent them
from holding a cup, water bottle, or picking up small objects. Creo Parametric was used to devel-
op the initial designs based on the conceptual drawings. The mechanism relies on a servo motor
that spins a series of worm gears to acquire the necessary torque and pressure needed to lift
ordinary items. The entire assembly is designed with strength and stability in mind. Additive man-
ufacturing technology was used in the design and development process to build the prototypes.
The CAD models were sliced and printed using CURA and printed on an Ultimaker 3. The materi-
al used was PLA (Polylactic Acid). The mechanism was properly stress tested for peak perfor-
mance, and the testing was able to properly identify design flaws.

DESIGNING, MANUFACTURING, AND TESTING
A HYDROPONICS SYSTEM

John H. Burns, Nimra Chaudhry & Mario A. Rodriguez

The purpose of this project is to design and build a functioning hydroponics system. Hydro-
ponics is a way of growing plants without the use of soil at an affordable price and without using
too much space. The system’s modules were designed and modeled in Creo and other compo-
nents such as the water pump and LED lights were purchased off the shelf. Creo part files were
converted into STL and Gcode files in order to 3D print a prototype. Our team designed a system
that would allow it to be used in small areas, both indoors and outdoors. The system was de-
signed in a vertical position so that it would take up minimal space. The vertical position also
allows water to flow up keeping the plants hydrated. The parts designed in CAD are made out of
PLA a cost-efficient material. The other parts acquired off the shelf include, the water pump with
tubing, the water basin which is essentially a bucket, pool noodles that would hold the plants
without leaking any water, and grow LED lights for assistance for indoor growing.

DESIGNING, MANUFACTURING, AND TESTING
A HYDROPONIC SYSTEM

Erica Camille P. Acio & Natalie T. Kiwanian

The goal of this project was to design, manufacture, and test a hydroponic system. A hydro-
ponic system is a system in which plants are grown without the need for soil. These systems are
useful for growing plants indoors without worrying about debris from having to change plant soil.
In most cases these systems also automatically water said plants and can be linked to a timer so
that all the individual will need to do is refill the nutrient-dense water in the reservoir. Creo Para-
metric was used to design the individual components of the system and its assembly. All the indi-
vidual components were off-the-shelf sourced and adjusted to fit the requirements of the assem-
bly. The base of the system is made from a PVC (polyvinyl chloride) pipe due to its ability to resist
corrosion when met with water for long periods of time. The plant holders that are placed in the
PVC pipe via holes on the surface were chosen for their ability to drain water whilst also allowing
the roots to consume said water. The water pump, air pump, water reservoir, and tubings were
bought online while a piece of poplar wood was used for the manufacturing of the frame for the
PVC pipe to have a stable slope. The model was gradually tested as the parts were received via
testing the angle for water runoff along with the power of the air and water pump respectively.
After these smaller optimization tests, the model was assembled and tested for overall
performance.

DESIGNING, MANUFACTURING, AND TESTING
A VERTICAL-AXIS WIND TURBINE

Nanak E. Chadha, Deev P. Kadakia & Dena B. Sheer

The goal of this project was to design and build a vertical-axis wind turbine that generates
enough voltage to charge an iPhone (5V-9V). A vertical-axis wind turbine contains vertically
mounted blades that harness the wind in order to generate energy through the rotation of its axis.
Strategic placement of the wind turbine in a windy location will cause the turning of the 3D printed
blades designed using Creo Parametric, processed using Cura, and then 3D printed with PLA
using the Ultimaker-2. The blade design was executed as outlined in the conceptual design. The
blades are connected to the generator with a 16mm wooden shaft whose bottom is connected to
the gearbox using couplings with a ball bearing to balance it out on the bottom of the wooden box
base. A gear reduction is used to achieve the required rpm for the motor from the rpm gathered
from the wind. The generator is housed in a laser cut Veneer wooden box with removable sides to
enable easy viewing of the generator and gearbox. The box provides a clean and sleek overall
design for the vertical-axis wind turbine. The final prototype displays a sturdy and effective design
that generates the desired voltage.

Where the Mind Is Without Fear1

Where the mind is without fear and the head is held high
Where knowledge is free

Where the world has not been broken up into fragments
By narrow domestic walls

Where words come out from the depth of truth
Where tireless striving stretches its arms towards perfection

Where the clear stream of reason has not lost its way
Into the dreary desert sand of dead habit
Where the mind is led forward by thee
Into ever-widening thought and action

Into that heaven of freedom, my Father, let my country awake.
