Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a tactile switch structure is used, then the switch can be operated, but it cannot supply sufficient mass power due to structural vulnerability
Solution Approach 1:
The spring electrode is divided into multiple directions (e.g., four-way division) to create multiple independent contact paths. Each division can independently conduct power, allowing the switch to supply mass power through parallel conduction paths while maintaining structural integrity through the distributed design.
Solution Approach 2:
The spring electrode is pre-formed with a divided plate shape and elastic properties before assembly. This preliminary structuring ensures that the electrode can immediately withstand and distribute mechanical stress from multiple directions, enabling both high power supply capability and structural reliability from the outset of operation.
2Power
If a P-type switch with complex structure is used, then power can be supplied, but mass production is not possible and durability is poor
Solution Approach 1:
The invention merges the P-type switch mechanism with the spring electrode structure into a single integrated component. The P-type switch is supported by the curved surface of the fastening bolt and directly presses the divided spring electrode, eliminating the need for separate complex mechanisms and enabling simplified mass production while maintaining power supply capability.
Solution Approach 2:
The divided spring electrode serves multiple functions simultaneously: it acts as the power conduction path, the mechanical switching element, and the structural support framework. This multi-functionality reduces the overall device complexity while maintaining the ability to supply mass power through its integrated design.
3Adaptability or versatility
If a separated type four-way switch is used, then four-axis movement can be operated, but the structure becomes complex with three separate components and 12 electrical circuits
Solution Approach 1:
The spring electrode is segmented into multiple directional divisions (e.g., four-way) within a single continuous plate structure. This segmentation enables multi-axis operation by providing independent contact paths in each direction while maintaining the electrode as one integrated component, thereby reducing the overall component count from three separate pieces to a single divided structure.
Solution Approach 2:
The single divided spring electrode structure performs multiple functions: it provides the mechanical framework for four-axis movement, serves as all electrical conduction paths (replacing 12 separate circuits), and maintains structural integrity. This universal design eliminates the need for multiple separate components while achieving full multi-directional operation capability.
4Ease of operation
If electrical conduction route is maintained only by pushing force on P-type spring, then the switch can operate, but wear and corrosion occur requiring additional plating process
Solution Approach 1:
The spring electrode is pre-formed with a divided plate shape that inherently provides both mechanical strength and electrical conductivity. This preliminary structuring ensures that the conduction routes are built into the electrode's geometry itself, requiring no additional plating processes while maintaining reliability against wear and corrosion through the robust divided structure.
