Yes, I think that this design project is interesting, but suffers from "wealthy person syndrome". If a couple bamboo poles can be easily lashed in a different way to deal with the back issues, that will likely suffice and solve the specified problem without creating an over engineered expensive "solution".

In order to be successful, as mentioned in other comments, such a project would need more end-users as active co-designers / field testers. Otherwise, it's a pure "design for design's" sake that won't get used. And that would be sad if some extra attention were the difference between a large, branded product company that would be able to reduce the damage and discomfort to millions vs. a concept on a shelf.

I ... don't think that the end users are going to care about buying a branded product. I think the best possible outcome is a simple adjustment that reduces the damage and discomfort. Seriously. Look at the the pictures of the end users. It's a stick of a certain size and diameter. The replacement has to be... a different kind of rope & stick arrangement, equally cheap, equally trivial to put together.
