Abstract
Generally the area of the spring's cross section increases from one end to the other. (Or decrease if you start to look from the other end.) It's geting thicker. Therefore the spring has a variable rate(lb/in), which increases from the weaker end to the stronger end, and is linear to the area of the cross section. And it will be used under compression only.
Description
See Picture 1., look at the cross section(with tilted strips) of spring wire, Claim 1 :The cross section is not traditionally a consistant cycle from spring's one end to the other, but a cycle with both top and bottom arches cut off for the spring rings to stack better. Hence less sliding between two adjacent rings, less curvy or bent for the whole spring's center line. And also the cycle could be made oval instead, which doesn't bring much change to the whole spring.
Claim 2: And also the area of the cross section increases through the whole spring, thus bring us the variable spring rate to our spring.
Claim 3: The whole spring coil's diameter doesn't change.
See picture 2a, when force applies to press the spring, the length change between two adjacent rings happens through the whole spring, but at the weaker end the rings has lower spring rate(lb/in) the length change is more obvious. The rings at the stronger end get closer much slower and can endure much stronger force. At one point(see picture 2b), the rings at the weaker end start to "stack together" and become idle; and this process repeat from the weaker end toward the stronger end, untill the spring and the force reach balance.
The weaker end provides spring users with more personable touch. The spring will easily fit in environment. For the same spring's applied model, the spring coil's weak end stacks more or less for different end users according to the different usage. It will help designer avoid the metal fatigue of other parts, reduce the wear and tear of other parts' joints, while the stronger end gives the designers a peace in their mind since this end can stand strong force(without the help of the air spring).
The applicable working range is much wider now. Spring coil could be made a lot wider, lighter, and shorter. These features are all good towards better design.
How fast the spring wire's diameter/gauge/thickness increase is very flexible to suit in every spring's different applied condition. Linear or not, staggering or not, are all fine, but the spring coil's diameter keeps the same to make sure it's weak end stack well. (For staggering design, applying force to the straighten spring wire at same angle as the two spring rings, and test if it breaks under certain force. If break happens, designer could make thickness shift more gradually.
Computer will be very helpful during spring's design and making. Since the formular for the force and stop point is hard to get, a experimental table could be prepared to estimate.
