Solution Overview
Problem
Conventional power-generating modules for wireless switches require a large pressing force when the end of a push button is pressed, leading to variations in touch-operation feeling, decreased operability, and increased production costs due to complex driving mechanisms.
Innovation Solution
A power-generating module with a simplified configuration using a plunger and interlocking links that transmit pressing force evenly to the power-generating unit, eliminating variations in touch-operation feeling and reducing production costs by ensuring consistent force transmission through a drive section with elastic biasing and interlocking links.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a rack arm engaging with the center of the push button is used to drive the power-generating section, then the pressing force is transmitted efficiently when the center is pressed, but a large pressing force is required when an end portion is pressed, causing variation in touch-operation feeling and degrading operability
Solution Approach 1:
The drive section is divided into multiple links (first link, second link, third link) that work together to transmit force. This segmentation allows the force transmission path to be optimized so that pressing any portion of the push button results in effective force transmission to the power-generating unit, eliminating the variation in touch-operation feeling while maintaining efficiency.
2Reliability
If a complex driving mechanism is used to ensure consistent force transmission, then operability and reliability are improved, but production cost increases
Solution Approach 1:
The drive section with multiple links serves multiple functions: it transmits force from any pressing location on the push button, provides mechanical advantage through the interlocking link mechanism, and ensures consistent operation of the power-generating unit. This multi-functional design achieves reliable and consistent operability without requiring an overly complex mechanism, as the links work together in a coordinated manner to accomplish all necessary functions.
3Device complexity
If a simple driving mechanism is used to reduce production cost, then device complexity is reduced, but variation in touch-operation feeling occurs and reliability decreases
Solution Approach 1:
The drive section employs dynamic links that can rotate and adjust their positions relative to each other. The first link, second link, and third link are interconnected in such a way that they dynamically adapt to pressing forces applied at different locations on the push button. This dynamic configuration ensures consistent force transmission and reliable operation while maintaining relative simplicity in the mechanism design.

AI summary
A power-generating module has a base, a power-generating unit that is placed in the base, a plunger that is placed in the base and that vertically reciprocates, and a drive section that interlocks with the reciprocation of the plunger and starts up the power-generating unit. The drive section is biased to a boost-up position where the plunger is boosted up. The drive section has at least two links that turn between the boost-up position and a press-in position where the power-generating unit is started up. Both ends of one of the links are turnably supported by the base. Both ends of another link are turnably supported by the plunger. The links turn in an interlocking manner by coupling to each other.
