Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple base assembly structures are provided to accommodate different wiper driving arms, then the adaptability is improved, but the device complexity and cost increase
Solution Approach 1:
The patent implements a universal base assembly structure that can accommodate multiple types of wiper driving arms through standardized coupling interfaces. The base assembly includes a main body with a coupling hole and positioning protrusions that work with corresponding positioning grooves and abutting surfaces on different wiper driving arm types, allowing a single base assembly design to serve multiple functions across different automobile models.
2Adaptability or versatility
If multiple base assembly structures are provided to accommodate different wiper driving arms, then the adaptability is improved, but the loss of substance increases due to component waste
Solution Approach 1:
The universal base assembly structure eliminates the need to manufacture and stock multiple different base assembly types for different wiper driving arms. By designing a single standardized base assembly that can interface with various wiper driving arm types through standardized coupling mechanisms, the system reduces material consumption and prevents component waste that would result from producing multiple specialized base assemblies.
3Adaptability or versatility
If multiple base assembly structures are provided to accommodate different wiper driving arms, then the adaptability is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The patent simplifies manufacturing by establishing a universal base assembly design with standardized features such as the coupling hole, positioning protrusions, and engagement interfaces. This standardized design can be mass-produced using the same tooling and processes for all wiper assemblies, regardless of the specific wiper driving arm type, thereby improving ease of manufacture while maintaining adaptability to different configurations.
