Switch Operation Device Overlapping Holding Members

The patent applies dimensionality change by overlapping the holding members for the click spring and speed change spring in the thickness direction (vertical arrangement) rather than placing them side-by-side in the horizontal direction. This vertical stacking approach reduces the horizontal footprint of the switch operation device while maintaining all necessary spring functions, directly resolving the contradiction between device size and spatial arrangement complexity.

The patent implements nesting by positioning the holding members one above the other in the thickness direction, creating a nested-like vertical arrangement where the click spring holding member and speed change spring holding member occupy overlapping horizontal spaces at different vertical levels. This nesting strategy allows both springs to coexist in a compact configuration, reducing overall device volume without increasing structural complexity.

The patent applies self-service by designing the holding members to automatically position and secure both the click spring and speed change spring through their overlapping vertical arrangement. The holding members themselves provide the positioning function without requiring separate latching mechanisms, as the vertical stacking configuration inherently guides and secures the springs in their correct positions, thereby maintaining reliability while reducing overall device complexity.

The patent merges the positioning and holding functions into the primary holding members themselves, rather than separating these functions into additional latching mechanisms. By combining the spring-holding function with the positional guidance function in the vertically stacked holding members, the patent achieves reliable spring positioning without adding extra latching components, thus resolving the contradiction between reliability and device complexity.
