This client would frequently bite themselves on the arms around the wrist with such force and frequency that the skin would break.
Any solution would have to be easy to put on in the event of an episode. Traditional solutions involve large arm braces that draw attention to the wearer in public.
How do you design something that is lightweight and stylish that does not draw attention to the wearer?
The final design was made of leather and velcro. Versions could be adapted to different clients depending on if they need protection farther up the arm or covering more of the hand.
The great thing about leather is that it is easy to work, safe for the end user, very tough and stylish all at the same time. This allows for a lot of rapid prototyping to workout size, coverage, and placement on the arm.
We cut the leather both manually and on a CNC crafting cutter. We found that manual was the easiest and we simply did not gain anything by adding to the complexity of the production process.
