Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional button configurations are used, then device simplicity is maintained, but input operation versatility is limited
Solution Approach 1:
The operation button is designed to perform multiple functions: it can be pushed to detect push operations, rotated to detect rotation operations, and the rotation amount can be detected to provide analog input. This multi-functional design allows a single component to replace what would traditionally require multiple separate controls, thereby improving input versatility without proportionally increasing device complexity
Solution Approach 2:
The patent replaces traditional mechanical switch-based detection with a resistance detection system. A conductive member with elastic properties contacts a resistance element, and the contact area changes based on rotation amount, converting mechanical rotation into analog electrical signals. This substitution enables more nuanced input detection while maintaining relatively simple device structure
2Measurement precision
If analog input detection is implemented, then input precision is improved, but device complexity increases
Solution Approach 1:
The patent utilizes changes in electrical resistance parameters to detect rotation amount. As the operation button rotates, the contact area between the conductive member and resistance element changes, altering the resistance value. This parameter-based detection method provides precise analog input information about rotation magnitude without requiring complex mechanical measurement mechanisms
Solution Approach 2:
The conductive member with elastic properties serves as an intermediary between the mechanical rotation operation and the electrical resistance detection. It translates rotational movement into varying contact area and corresponding resistance changes, enabling precise analog detection while keeping the overall system structure relatively simple through this mediating component
