prototype 4

 prototype 4:

by combining prototype 2 and 3 we get prototype , a flexible but harder front and a soft foam as backing. the harder material distributes the forces more across the foam, while the foam adjusts to the shape of the knee.

Elements of experience:

Positive expected: forces are distributed more

Positive unexpected: 

Negative expected:thick

Negative unexpected:debris is still noticeable
