Prototype 15

Prototype 15:

This one is a filling made by sponges. It has three parts so that its a bit more flexible, because it's rather hard and would be difficult to use if the parts where pasted together.

Elements of experience:

Positive expected: 

Positive unexpected: 

Negative expected:

Prototype 14

Prototype 14:

This one is the combination of prototypes 12 and 13, so it has it soft qualities for more comfort and a harder shell so that hard objects are difficult to feel through it.

Elements of experience:

Positive expected: 

Positive unexpected: 

Negative expected: 

Negative unexpected: a bit to hard

Prototype 13

Prototype 13:

This is a collection of 7 layers of plastic with ribs which are oriented in different directions.

Elements of experience:

Positive expected: 

Positive unexpected: with the different directions of ribs it becomes a stronger whole

Negative expected: 

Negative unexpected:

prototype 12

prototype 12:

The next number of prototypes are the ones that concern the filling of the previous prototypes 9,10 and 11.

This filling is made from layering fabric ant stitching it down in a square pattern.

Elements of experience:

Positive expected: the stitching make it less thick 

Positive unexpected: 

Negative expected: you can still feel hard object through it 

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

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
