Pulleys and Release Mechanisms

We needed to make some progress with our form, so we whipped together a quick cardboard prototype. At first we were testing movement by swinging them against each other, side to side. This looked unintentional and was rather impossible to control. Prof. John Marshall mentioned that the duality in the form looked like a joint, and suggested that we explore the movement in terms of this interpretation. By rigging up a pulley system with string and human power we began exploring this idea.



This worked great, but the system needs to be self contained. Ideas were thrown around, winches, spools, gears, releasing mechanisms.... and we came up with this:


By shaving off part of the gear, we were able to create a release mechanism. When the larger gear (connected to the panel) came in contact with the bare area of the small gear, the weight of the panel will cause the large gear to drop, or release. I drew up a few ways to possibly create smoother movement.
