Prototyping Round 2

In this case, the team is not ready to prototype with more expensive materials. Instead, they decide that doing one or two more iterations with cardboard to get the right cuff length would be useful. This is cheap and quick prototyping that will give the team a better idea of how to create a more expensive and time-consuming prototype.

The team builds two more prototypes until an arm cuff shape has been finalized, using input from the co-designer. It is time to try out more realistic prototyping. Here are the three major components:

1. The arm cuff is now made out of wood with the design decided on from the cardboard prototypes.
2. The team decides to outsource the ball joint design, buying an off-the-shelf component and designing a connector between the clamp and ball joint and arm cuff.
3. Due to metal working expertise in the team, the clamp was prototyped in parallel with the arm cuff using cheap metal scraps.

The team assembles the arm cuff, ball joint, and clamp for the next prototype.
