Prototype 31

Prototype 31:
This prototype you can close with push buttons. Because the first test with this one was really clear that it is just to difficult to use, this one isn’t going to be tested on the client.

Elements of experience:
Positive expected:
Positive unexpected:
Negative expected: not easy to close. Sewing on the buttons take a lot of time
Negative unexpected: When sewing the buttons on, the fabric don’t stay in place, it wrinkles a lot.The spaces between the buttons have the tendency to break.

Prototype 35

Prototype 35:
Here we test the first kind of filling. Here she made a shape in the foam by pressing down onto it with her knee. This way we knew the points where the pressure is highest. Here we just cut a hole around it, the next prototypes are going to test if making a whole in the place where the knee comes is better




Elements of experience:
Positive expected: sits good
Positive unexpected: not to hard 
Negative expected: 
Negative unexpected: the PU compresses and becomes thinner after a while

Prototype 30

Prototype 30:
Here the bandages are again sewed on the envelope. One closing method is one you can find on bra’s the other is a velco connection where one piece is split in two to have more choice on the length of the bandages.



Elements of experience:
Positive expected: bra elements are less noticable
Positive unexpected: the bra element is easy to sew on , easily reachable
Negative expected: 
Negative unexpected: not a lot difference on the different use of Velcro

Results from testing on 21/03

For the bandage locking the order from bad to good is:

  • basic velcro stips 
  • velcro strips where one end in bigger that the other 
  • velcro strips sewed together and pult though a hole
  • bra closing
The next steps on the envelop are going to be on the fabric that touches the ground and the skin. These prototypes will be made in pairs, one with the velcro strips sewed together and one with the bra closing.


For the filling the order from bad to good is:
  • PU with fabric, with the fabric on top (prototype 41)
  • rubber band with filling( prototype 39)
  • foam with sizes from feline with hole (prototype 36)
  • foam with size from Timothy with hole and filled whole( prototype 37 & 38)
  • PU with fabric, with the fabric on the ground (prototype 40)
  • foam without the whole in it (prototype 35)
  •  
     

Prototype 29

Prototype 29:
This prototype has the bandages sewed to the envelope (not like 28). Here you can close the straps with: 1. Velcro at the side, both strips evenly large
2. where the Velcro is used in a different way. The two connective strips are sewed together, a hole is made in one side of the envelope where you can pull the strips though and adjust the bandage at your preferences.



Elements of experience:
Positive expected: easier to use
Positive unexpected:
Negative expected: hole must be bigger for an easy use and there is a stronger grip needed
Negative unexpected:

Prototype 28

Prototype 28:
The next few prototypes are envelopes to put filling in. Most of them are made from compression sock bandages, every time there are two different ways to close the prototype.
Prototype 28 you close at the back of the leg with velcro and the filling isn't immediately connected to the bandages. This connection is made with velcro




Elements of experience:
Positive expected: easy to make
Positive unexpected: 
Negative expected: 
Negative unexpected: the velcro used is connected with special glue to the fabric, but this one doesn't connect well to the jeans fabric.

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

comparing filling

We asked to put the filling in the order she liked best.


This was a difficult question but it was clear that de silicone and the donut shapes had the most succes. She asked for combine these two (prototype 5 and 19).
1) silicone prototype5 (not the hard shell)
2) donuts prototype 19
3) sponge prototype15
the mousse was the least favorite

Comparing the connections

Here we asked to put the three different ways of connection in the order she likes best.
From left to right the best until the least favorite.
prototype 27, 23 and last 9

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: 
Negative unexpected: 
   

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: 
Negative unexpected: 
 

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 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 18 and prototype 19

Prototype 18: test prototype 8

Elements of experience:
Positive expected: 
Positive unexpected: 
Negative expected: a bit to hard, not comfortable
Negative unexpected: silicone doesn't stay in place

Prototype 19: test prototype 8 with some changes

Elements of experience:
Positive expected: is softer than prototype 18 
Positive unexpected: 
Negative expected: the shell is to small
Negative unexpected: 

Prototype 17

Prototype 17:
While searching on the internet we noticed that knee braces are shaped like a donut around the knee. So when we saw these donuts normally used for hairdots, we got the idea to use these.

Elements of experience:
Positive expected: force is distributed around the knee
Positive unexpected: 
Negative expected: a hard material if squeezed together
Negative unexpected: weird feeling from the materials , knee touches ground in the middle
