Our big idea, by the end of the day, was to create a bracelet that extended itself to cover the wearers arm depending on their heart rate which would display the wearer's temperature and if they needed a sleeve or not. Originally, we wanted to make a bracelet that inflated and deflated with your heart beat. Then, we got the idea to instead make a bracelet that actually helped the wearer by creating a shelter or something for warmth based on one's heart beat. From this emerged and idea for a bracelet that would have extra fabric, or in this case paper, that based on temperature it could extend itself to make a sleeve. Our first thought was to use an accordion fold, but we had trouble using just this fold and making it a circle, so we made our bracelet a hexagon and used a bunch of different pieces of accordion folded paper to create our first prototype. Then, john suggested to us that to make this out of one piece we could use a 3 jointed fold in corners that would expand and be made smaller when the sleeve was no longer needed. But, while John was showing us the 3 jointed fold, I got the idea to only use a 3 jointed fold. I proposed the idea of using a square with multiple 3 jointed folds on it and placing it on the wearers arm in a diamond shape and having bands on both the ends of the diamond. The band further up on the wearers arm would move in whenever a sleeve wasn't wanted which would make the square fold up into a gem type shape on one's wrist. We decided to change our design to that because it looked much better and it was less bulky and more simple.
