Prototype 45

Prototype 45:

Because with prototype 44 there where problems with fillings that didn't stay in place an other method of sewing it on is used. This 'final' prototype for testing stayed with the client afterward to test it some more on her own.

Elements of experience:

Positive expected: it moves less then prototype 43

Positive unexpected: 

Negative expected: the filling still becomes thinner every time it is used. You can see on the film that when feline moves around the velcro strip on the side loosen up a bit

Prototype 43

Prototype 43:

Like in the video of prototype 42 is quoted , its hard to walk on one. So we took her second favourite envelope prototype 29 and combined it with the other filling from prototype 35. Here we didn't use extra filling on top of that.

Elements of experience:

Positive expected: its better with less filling on top

Positive unexpected: 

Negative expected:  a little bit off filling is needed

Negative unexpected:

Prototype 44

Prototype 44:

The combination of prototype 43 is again used here with the difference that the filling on top of the envelope(the part that doesn't touch the ground) is from prototype 12

Elements of experience:

Positive expected: 

Positive unexpected: 

Negative expected: filling becomes thinner every time it is used

Negative unexpected: there is a movement of the filling

Prototype 20 and 21

Prototype 20: testing prototype 9 in combination with prototype 14

Elements of experience:

Positive expected: 

Positive unexpected: 

Negative expected: first strip still goes down to the popliteal, too hard

Negative unexpected: 

Prototype 21: testing prototype 9 in combination with 15

Elements of experience:

Positive expected: better (softer) than prototype 20

Positive unexpected: 

Negative expected: 

Negative unexpected: 

prototype 9

prototype 9:

Different envelops were made, each one has different straps, so that the straps can be tested with different fillings. Each envelop is made by stitching two patches of fabric and a velcro closure.

This one is made with elastics with two different widths: 20mm and 30mm

Elements of experience:

Positive expected: stays on the leg

Positive unexpected: 

Negative expected: too wide

Negative unexpected: the top elastic keeps going into the popliteal
