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 28:

de banden worden bevestigd met bh haakjes (bovenste band)

Elements of experience:

Positive expected:minder voelbaar

Positive unexpected: goeie locatie aan de zijkant, makkelijk te bereiken

Negative expected:

Negative unexpected: 
door verslechterende motoriek kan dit wel moeilijker worden in latere stadia van MS

Prototype 26 and 27

Prototype 26: testing prototype 10

Elements of experience:

Positive expected: 

Positive unexpected: 

Negative expected: 

Negative unexpected: band still slips down between the knee

Prototype 27: testing prototype 26 with a cut in so it doesn't slip between the knee

Elements of experience:

Positive expected: The problem of 26 is helped by cutting a half circle in it 

Positive unexpected: 

Negative expected:

Prototype 24 and 25

Prototype 24: testing prototype 23 with 17

Elements of experience:

Positive expected: softer

Positive unexpected: 

Negative expected: 

Negative unexpected: weird feeling, when moving the knee touches the ground

Prototype 25: testing prototype 24 in combination with 12

Elements of experience:

Positive expected: the problem with your knee touches the ground is solved

Positive unexpected: 

Negative expected:

Prototype 22 and 23

Prototype 22: testing prototype 11

Elements of experience:

Positive expected: 

Positive unexpected: 

Negative expected: to big

Negative unexpected: the stitching made that sock was too tight

Prototype 23: testing prototype 22 with a little snit to make less tension

Elements of experience:

Positive expected: less tension 

Positive unexpected: 

Negative expected: 

Negative unexpected: 

prototype 11

prototype 11:

In this prototype, the compression stockings were used in a different way. Here you need to put the envelop on just like you would do with a sock.
There is a whole made so that there is no irritation in the popliteal. This is stitched around so that there is no fluff coming loose from the sock.

Elements of experience:

Positive expected: the hole leaves enough place for the knee 

Positive unexpected: 

Negative expected: 

Negative unexpected: by stitching the border of the hole it becomes less flexible and less stretchable

prototype 10

prototype 10:

This prototype is based on 9 with the difference that the elastic straps are replaced by compression socks.

Elements of experience:

Positive expected: these are also easy to tighten

Positive unexpected: 

Negative expected: the socks fluff off

Negative unexpected: difficult to estimate the length of the socks
