Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional wire harness designs are used with fixed holding members, then the structure is simple and easy to manufacture, but the versatility to accommodate various vehicle models and specifications is limited
Solution Approach 1:
The wire harness system is divided into modular components: holding members, fixing members, and tubular members that can be independently configured and assembled. This segmentation allows different combinations to be used for different vehicle models while maintaining a standardized base design, thereby improving versatility without proportionally increasing overall complexity.
Solution Approach 2:
The holding members and fixing members are designed with universal interfaces and standardized dimensions that can accommodate multiple vehicle models and specifications. The tubular members serve multiple functions by providing both structural support and routing pathways, reducing the need for model-specific custom components and enhancing adaptability.
2Adaptability or versatility
If multiple custom designs are created for different vehicle models, then versatility is improved, but design and molding costs increase
Solution Approach 1:
A standardized family of holding members, fixing members, and tubular members is designed with universal mounting interfaces and dimensions that work across multiple vehicle models. This allows a single set of tooling and molds to produce components for various applications, significantly reducing design and molding costs while maintaining compatibility with different vehicle specifications.
Solution Approach 2:
The design allows for parameter variations (such as length, positioning, and orientation) of the holding and fixing members within a standardized framework. By adjusting these parameters rather than creating entirely custom designs, the system achieves model-specific adaptability using the same base component family, thereby controlling manufacturing costs.
3Adaptability or versatility
If more components are added to achieve customizable configurations, then versatility is enhanced, but weight increases
Solution Approach 1:
The system uses segmented, modular components that can be selectively assembled based on specific vehicle requirements. Rather than using a single heavy custom-designed harness for each model, only the necessary holding members, fixing members, and tubular members are installed, optimizing the weight-to-versatility ratio by including only what is needed for each application.

AI summary
A wire harness includes a wiring member, an exterior member through which the wiring member is inserted, and a protector that is fixed to a vehicle and holds the exterior member. The protector includes a holding member that holds the exterior member, a fixing member that is fixed to the vehicle, and a tubular member that is formed in a tubular shape and on which the holding member and the fixing member are disposed. At least one of the holding member or the fixing member includes a columnar structure that is formed in a columnar shape and is slidingly fittable into the tubular member.
