I have an idea (I can't tell you what the invention is because I can't shoot you from here.) which employs a disk or dome spring of a type that has two stable states. Actually, several applications for such a spring come to mind. Anyway, all the springs I've found on line pop back when released; I need one that has to be pushed back from the other side. Obviously, such a spring can be made; we've all seen dents in sheet metal that pop back when pushed the other way; ask any auto body mechanic. I'd like to know exactly how such a spring would be manufactured and how to calculate its force to distance characteristics, durability, etc. I expect that the graph of force to distance will rise to a maximum, level off briefly, then drop steeply to a negative value, level off briefly and return to zero. Depending on construction details, it may or may not be symmetrical about zero force. Is anyone aware of a manufacturer who makes such a spring? Do I have to invent the spring, myself? Are you all running to the patent office ahead of me? I haven't even found a detailed description of the geometry of existing dome or disk springs. Anyone know of a good source? |

There are many spring configurations that in essence provide an overtoggle force and which are simple to calculate. Is it necessary to to have a disk shape? |
