In the Summer of 2014, I had this idea idea for the first time. I will create a machine that pushes on my maxilla to move it forward. This force can be replicated by sticking your thumb on your palate, and pushing forward. If you do it for several seconds, with a high enough force, you feel a strain on your cheek area, just below the eyes. I simply needed to create a machine that will replicate this force, and I would wear when sleeping or at home. The concept is simple, but implementation has turned out to be pretty challenging.
I got my hands on a meccano set, and immediately built this contraption. It was heavy, uncomfortable and impossible to sleep with. It put so much reciprocal force on my forehead that it would wrinkle my skin and give me headaches. I still tried to wear it as much as possible, but it needed a lot of improvement.
I also found the initial design sketches I made, when I first got this idea. This is what I tried to build with the meccano set.
