Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electronics and energy storage device are integrated into the key bow, then the key can provide wireless communication and user feedback functions, but the key structure becomes more complex and assembly becomes more difficult
Solution Approach 1:
The housing is nested within the frame structure, with the electronics and energy storage device arranged inside the housing. This nested arrangement allows the key to provide wireless communication and user feedback functions while maintaining a compact and manageable structure, reducing overall complexity despite the added functionality.
2Strength
If the frame is rigidly connected to the key shank, then torque transmission strength is improved, but the manufacturing and assembly process becomes more difficult
Solution Approach 1:
The key is divided into separate components: the frame, the housing, and the key shank. The frame and key shank are designed as separate parts that can be manufactured independently and then assembled together through rigid connection. This segmentation allows for optimized manufacturing of each component while achieving the required torque transmission strength through the connection between parts.
3Reliability
If the frame encloses the housing containing electronics, then the key provides stable torque transmission and protected electronics, but the assembly process becomes more complex
Solution Approach 1:
The frame and housing are designed as complementary components that fit together to enclose the electronics and energy storage device. This merging of structural elements provides stable torque transmission and protected electronics while the integrated design reduces assembly complexity by minimizing the number of separate components and simplifying their integration.
