TECHNIQUES

Union Technique Subtract

Union technique are the Subtract a part of the
combination of two things cardboard and bottles that
into one. For example, the we don’t use. We use scissors
plastic bottle and the to cut the cardboard and the
cardboard will union to bottles. We cut the cupboard
produce eco cooler. into the circle shape and cut
the bottles into half along the
body.

INSTRUCTIONS AND SEQUENCES

● Measure the size of the table fan

1 ● Draw the circle on card box using compass
according the size of the table fan then cut the
circle using scissors

● Using a pair of scissors, cut the bottle in

2 half along the body of the bottle

INSTRUCTIONS AND SEQUENCES

● Draw a circle on the cardbox section based

3 on the size of the bottle cut in half then cut
the circle using scissors

4 ● Place each bottle on the circle of the
cardbox that has been cut. Then glue it

INSTRUCTIONS AND SEQUENCES

● Make a small hole in the cardbox by using

5 scissors
● Tie the cardbox to the table fan by using a
cable tie.

DISCUSSION

Why we choose plastic bottle ? How warm and cold air How many blades should a

- It easy to be shaped.
- It become soft when heated When blow with wide open mouth, The more blades a fan has, the

environment will not polluted.

DISCUSSION

For the best result :

1) Use in a room that is
not too spacious

2) Suitable for use when
studying in the room

3) Distance within two and
half feet from the fan

CONCLUSION

In conclusion, this eco cooler is an interesting idea to try and design. This is because
the items to create and produce are items that are very easy to find especially around
our homes. Therefore, this eco cooler becomes an eco-friendly design because we only
need to use used items. In addition, we can also reduce waste and waste disposal
because the items to produce this eco cooler can be used and recycled. The eco cooler
also has a role to increase the coolness without having to use a lot of electrical
energy. Therefore, the eco cooler also has a cooling function without having to waste
electricity consumption.
