Jellypods Zipper Mk II/III under way

It has been a pretty quiet few weeks on the Jellypods blog, but behind the scenes there is lots of work going on to fix the zipper issues we discovered in the first prototypes revealed in the last few blog posts from the China trip.

Below you can see a shot of the first zipper molded in hard silicone, which was very bulky, unwieldy and despite looking good in CAD, did not work at all.

So after a few days of hard thinking, we went back  to an original concept from a few months back and our friends in China molded a protoype of that old deisgn to see if some new ideas and materials would work in practise.

The Mark II zipper has been moulded in a special mix of hard plastics and other special materials, and bonded to a rough of the top of a Jellypods body. This zipper was never really expected to work fully functionally, it was what Formula One teams call a “mule” – a development half-breed between a racehorse and a donkey:

Although never expected to be brought to life in final form, this mule gives us is enough solid information to move forward with the Mk III zipper, which will hopefully be a big step forward and close-to-final.

And the sketches for that design, which were worked up in a notebook  on an airplane flying between Sydney and San Francisco, are already sent to our partners for working up in to CAD and moving forward to the next steps.
