Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a binding member is inserted through an insertion hole in the protective member, then the binding member can be positioned for routing the wiring member, but the binding member may become trapped or lost inside the routing space, reducing workability
Solution Approach 1:
The temporary retention projection is provided in advance within the routing space to prepare for receiving the binding member. This preliminary preparation ensures that when the binding member is inserted through the insertion hole, it will be automatically retained by the projection, preventing it from becoming trapped or lost during the routing process.
Solution Approach 2:
The temporary retention projection acts as an intermediary element between the insertion hole and the final binding position. It provides a temporary holding point that facilitates the routing operation by securing the binding member in place during the process, then allows easy detachment when routing is complete.
2Ease of operation
If the binding member is temporarily retained during routing, then the routing process becomes easier and more controlled, but the structure of the protective member becomes more complex
Solution Approach 1:
The protective member is segmented into distinct functional elements: the insertion hole for introducing the binding member, the temporary retention projection for securing it during routing, and the routing space for guiding the wiring member. This segmentation allows each element to perform its specific function efficiently while keeping the overall structure manageable.
Solution Approach 2:
The temporary retention projection is designed to automatically engage with the binding member through its own elastic deformation, without requiring additional mechanisms or external assistance. The projection's elasticity allows it to flex outward to receive the binding member and then automatically retain it, providing a self-service retention function that simplifies the overall structure.
3Manufacturing precision
If the binding member is securely retained during routing, then the binding position is controlled and accurate, but the binding member cannot be easily adjusted or repositioned
Solution Approach 1:
The temporary retention projection is designed with elastic properties that allow it to dynamically adapt to the binding member. During insertion, the projection flexes outward to accommodate the binding member, then automatically retains it in a controlled position. After routing is complete, the binding member can be easily removed by applying slight force to overcome the elastic retention, providing both precision and adjustability.
Solution Approach 2:
The retention force of the temporary retention projection can be adjusted by changing parameters such as the projection's dimensions, material properties, or geometric configuration. This allows optimization of the retention strength to achieve precise positioning during routing while maintaining ease of detachment when adjustment is needed.

AI summary
A wire harness manufacturing method includes: an insertion step (S1) of inserting a binding member through an insertion hole of a protective member; a temporary retention step (S2) of inserting the binding member through a temporary retention notch in a state where the binding member is inserted through the insertion hole, and hooking the binding member, which is in a state of being inserted through the temporary retention notch, to the temporary retention projection to achieve temporary retention of the binding member on the temporary retention projection; a routing step (S3) of routing a wiring member in a routing space in a state where the binding member is temporarily retained on the temporary retention projection; and a binding step (S4) of detaching the binding member.
