Vacuum Bulb Self-Centering Coil Spring Assembly

The patent applies this principle by using a flexible membrane with integrated elastic fingers instead of rigid elastic strips. The membrane structure eliminates triple points and openings that compromise dielectric strength, while the elastic fingers provide the necessary centering force through controlled flexibility. This resolves the contradiction by maintaining centering precision without creating weak points in the dielectric barrier.

The patent employs composite construction by integrating multiple functional elements (membrane, elastic fingers, centering protrusions) into a unified structure. The combination of flexible membrane material with elastic finger elements creates a composite system that simultaneously provides mechanical centering and maintains dielectric integrity, avoiding the need for separate centering components that would create openings.

The patent merges the centering function with the bulb element structure itself by integrating elastic fingers directly into the membrane that forms part of the bulb assembly. This eliminates the need for separate centering components and costly installation steps like soldering, as the centering elements are factory-integrated and require no additional assembly operations.

The integrated elastic fingers provide self-centering functionality that automatically adjusts during assembly without requiring external intervention or costly installation procedures. The centering action occurs naturally through the elastic deformation of the pre-positioned fingers, eliminating the need for skilled labor or expensive soldering steps.

The patent applies dynamics by using elastic fingers that can dynamically adjust their deformation state based on temperature and mechanical conditions. During cold transport, the fingers remain flexible enough to accommodate shocks and maintain centering. During hot cycles, the same fingers adapt to thermal expansion while maintaining centering precision, providing reliable centering across all operational conditions.

The patent utilizes parameter changes by designing elastic fingers with specific material and geometric properties that allow them to function effectively across a wide temperature range. The elastic modulus and dimensional parameters are optimized so that the fingers provide adequate centering force both at ambient temperature during transport and at elevated temperatures during operation, eliminating the need for separate cold and hot centering mechanisms.
