Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional button structure with large volume is used, then reliability and indicating function are ensured, but device space is excessively occupied
Solution Approach 1:
The patent transitions from a conventional single-layer electrode structure to a multi-layer stacked electrode structure. The first and second electrode layers are arranged in different spatial dimensions (layers) with a predetermined interval between them, allowing the button mechanism to achieve reliable electrical connection while reducing the overall planar footprint and occupying less device space.
Solution Approach 2:
The patent employs a nested arrangement where the conductive portion is positioned to simultaneously contact multiple electrode layers (first and second electrode layers) through the predetermined interval. This nested configuration allows the actuating structure to trigger multiple electrode layers in a compact arrangement, reducing the button mechanism volume while maintaining conductive reliability.
2Adaptability or versatility
If conventional button structure with large volume is used, then reliable electrical connection is achieved, but arrangement flexibility in limited space is reduced
Solution Approach 1:
By arranging electrode layers in multiple dimensions (stacked configuration with predetermined intervals), the patent enables more flexible placement options within limited mechanical spaces. The multi-layer structure allows designers to optimize button arrangement flexibility while maintaining smaller overall volume compared to conventional single-layer structures.
3Ease of operation
If indicating function with light emission is added, then user feedback is improved, but mechanical space occupation increases
Solution Approach 1:
The patent integrates the indicating function by emitting light from the button structure itself, merging the indication capability with the existing button components. This approach eliminates the need for separate indicating modules, thereby providing user feedback through light emission while occupying minimal additional mechanical space.
