Piezo Ignition Switch Layout for Short-Travel Vehicle Operation

The patent replaces the conventional mechanical switch contact system with a piezoelectric sensor system. Instead of using mechanical contacts that require long insertion paths and complex mechanical structures, the invention uses a piezoelectric element that generates an electrical signal in response to mechanical stress. This substitution eliminates the need for complex mechanical switching mechanisms while maintaining the switching function, directly resolving the contradiction between ease of operation and device complexity.

The patent changes the fundamental parameter of switching detection from mechanical position (insertion depth) to mechanical stress (pressure). The piezoelectric element responds to the applied force regardless of the exact insertion depth, allowing for a shorter, more user-friendly insertion path while maintaining reliable switching detection. This parameter change from position-based to force-based detection resolves the contradiction between reliability and ease of operation.

The patent replaces the mechanical contact and moving component system with a piezoelectric sensing system that has no moving parts. The piezoelectric element is a solid-state component that generates an electrical charge in response to applied stress, eliminating mechanical wear, contact bounce, and susceptibility to environmental contamination. This substitution directly addresses the contradiction by reducing mechanical complexity while improving environmental resistance.
