Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional wire harness routing structure is used, then the basic routing function is achieved, but the assemblability to the vehicle is insufficient
Solution Approach 1:
The patent combines the routing member, sound insulation member, and heat insulation member into a single integrated assembly. The routing member is sandwiched between elastic members that are coupled to sound and heat insulation layers, creating a unified structure that performs multiple functions simultaneously. This merging improves assemblability by reducing the number of separate components that need to be installed individually.
Solution Approach 2:
The routing structure is designed to serve multiple purposes: guiding the wire harness, providing sound insulation, and offering heat insulation. The elastic members not only hold the routing member but also provide cushioning and insulation properties. This multi-functionality addresses the assemblability issue by consolidating multiple protective and insulating functions into a single installable unit.
2Manufacturing precision
If the routing member is fixed rigidly to the dash panel, then positioning precision is improved, but flexibility and adaptability are reduced
Solution Approach 1:
The patent employs elastic members instead of rigid fasteners to attach the routing member to the dash panel. These elastic members can deform and adapt to variations in the dash panel surface and routing member position, providing both positioning precision and flexibility. The elastic properties allow the structure to accommodate manufacturing tolerances and installation variations while maintaining stable positioning.
Solution Approach 2:
The elastic members change their physical state from a relaxed condition to a compressed condition when夹持 the routing member, allowing them to adapt to different positioning requirements. This parameter change enables the same elastic member to provide both precise positioning when compressed and flexibility when deforming, resolving the contradiction between positioning precision and adaptability.
