Durability
Layer 2 was added to the product to insure durability.– It will protect the plastic from scratches– Keep the plastic from getting worn out

39
Cost
The cost to make the product is fairly cheap Most of the project’s cost comes from the
prototype machine The cost to produce one spike cover (both
parts) is about $25 (according to Stephen Buchs)
![Page 40: Cleat Covers](https://reader033.fdocuments.in/reader033/viewer/2022061423/5681677c550346895ddc80a6/html5/thumbnails/40.jpg)
40
Refining the design
There should be two layers to the shoe– Plastic: serves as the protection of the spike– Rubber: serves as a safety precaution and
increases durability of the product There was no way of making a solution that
could fit all spikes We chose the Nike Haurachi as our model shoe

Design Development
2 Parts to the solution– The front of the shoe– The sole of the shoe
Each part is divided into 2 layers– Top Layer: made of plastic– Bottom Layer: made of rubber

Test Procedure
Fit Does the spike cover fall off? Do the spikes fit within the holes? Do the covers fit the portion of the shoe?
Safety Is it slippery? Is the cleat still balanced?
Weight Capacity Appearance

50
Test Procedure (Cont’d)
Does the spike cover protect the spikes? Do spikes become damaged when wearing
the spike cover? Does it eliminate the need to change shoes? Is it faster to use the spike cover than to
bring an extra pair of shoes?

Test Results
Failed the fit test Dimensions were not correct Spikes are different sizes Angles were incorrect

53
Fixing the Problem
Redo the measurements and drawings Realized that pressure is not the best way to
make the spike cover stay on. – Over time, it will become loose.
New Solution = Magnets
![Page 54: Cleat Covers](https://reader033.fdocuments.in/reader033/viewer/2022061423/5681677c550346895ddc80a6/html5/thumbnails/54.jpg)

Magnets
Magnets will be implanted into the second layer of the product.
They will make the fit of the product more efficient.
