Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional power switch with power adjustment function is used, then the power adjustment function is achieved, but the size becomes large and operation becomes laborious
Solution Approach 1:
The patent employs a movable contact that can dynamically adjust between different power levels (first power level when separated, second power level when contacted) by simple linear movement along the inclined surface, eliminating the need for complex multi-position switches while maintaining power adjustment functionality with minimal operator effort
Solution Approach 2:
The patent changes the electrical connection parameter by utilizing the inclined surface geometry to automatically adjust contact pressure and electrical connection state, where the moving contact's position on the inclined surface directly determines the power level, achieving power adjustment through geometric parameter variation rather than complex mechanical positioning
2Adaptability or versatility
If a conventional power switch with power adjustment function is used, then the power adjustment function is achieved, but the size becomes large
Solution Approach 1:
The patent merges the power adjustment function with the basic circuit switching function into a single integrated mechanism. The moving contact simultaneously performs both circuit opening/closing and power level adjustment, eliminating the need for separate control mechanisms and reducing overall switch size
Solution Approach 2:
The moving contact serves multiple functions: it acts as the circuit breaker contact, the power adjustment element, and the electrical connector all in one component. This multi-functionality eliminates redundant parts and reduces the overall footprint of the switch device
