Patent ID: 8145454

Claim:
A method for improving the fatigue life of a flexible wobblefram, comprising: forming a flexible wobblefram with a fixed outer edge and a solid center region utilizing a punch and a die, wherein said flexible wobblefram is modeled with at least one shell element; adding at least one corrugation between said fixed outer edge and said solid center region of said flexible wobblefram, wherein said solid center region is brazed with at least one external lever; precisely evaluating and optimizing a profile, a number and a height of said at least one corrugation utilizing a finite element analysis model in order to achieve a higher fatigue lifetime with respect to said flexible wobblefram without affecting one or more operating characteristics of a micro switch thereof; and optimizing said flexible wobblefram with respect to a rotational stiffness of said flexible wobblefram and said height of said at least one corrugation in accordance with said finite element analysis model.
