That story is apocryphal.OP, not sure if you are familiar with the "story" of NASAs design brief and project for a space pen.....meanwhile the Russians came up with a very cunning solution.
Cable laid ropes have a preferred coiling direction. Perhaps work towards a cable that practically coils itself to a diameter that fits the bag. Maybe some regularly spaced clips too along the length.I was considering this but was thinking how a thick cable would be able to arrange like that (any ideas?), thanks for the help though
For use as my market research could use please re-state the problems you have with your parking holder, many thanksFor your design technology course, may I suggest that you design a better parking holder for the type 2 connector, than any currently on the market. One that latches, provides a degree of rain or snow protection and is easy to mount to typical domestic dwelling exterior wall.
I thought cable cores were spiral wound so there is no shortening/lengthening of the coresWhen you coil a flex that has been lying flat, it likes to acquire one complete rotation of the coil as it gets put into one loop. This way, the individual cores don't get stretched to alonger or shorter lengths. If the coil isn't rotated, and you insist on winding it flat, the outer cores will be at a larger radius than the inner cores, so there's a lot of stress (force) and strain (defoemation, stretching/compressing) going on.
