Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different structures are used for attaching various exterior components (soundproofing, protection, heat radiation, shielding) to electric wires, then the attachment function is optimized for each specific component, but the number of process types increases
Solution Approach 1:
The patent applies universality by designing a single exterior component that simultaneously performs multiple functions: soundproofing, protection, heat radiation, and shielding. This is achieved by integrating different functional layers or materials within one component structure, allowing it to be attached to electric wires using a unified process rather than requiring separate specialized components for each function.
2Reliability
If multiple process types are used for attaching various exterior components, then specific functional requirements are met, but manufacturing complexity and time increase
Solution Approach 1:
The patent merges multiple attachment processes into a single unified attachment operation. By integrating soundproofing, protection, heat radiation, and shielding functions into one exterior component, the manufacturing process attaches all these functions simultaneously in one step, rather than requiring separate attachment operations for each functional layer, thereby improving productivity while maintaining reliability.
3Ease of manufacture
If a unified attachment method is used for various exterior components, then manufacturing process is simplified, but the ability to optimize for specific component functions may be reduced
Solution Approach 1:
The unified attachment method maintains adaptability for specific component functions by incorporating multi-functional design within the exterior component. The component is structured to provide soundproofing, protection, heat radiation, and shielding capabilities simultaneously, allowing the single attachment process to serve all these functions without compromising their specific optimization requirements.
