Hinged Wiring Module for Bent Door Harness Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
It is difficult to arrange and hold a door harness in a bended state along the arrangement target part of a door trim, making it challenging to manage the wiring effectively.
Innovation Solution
A wiring member integrated module comprising a first base member and a second base member, where the second base member can change its state from holding the wiring member on an extension of the arrangement target part to a bended state, allowing easy holding of the wiring member in a bended configuration using a hinge part or weakened connection, and optionally with a fixing part to maintain the bended state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the door harness is routed along the main surface of the door trim, then the wiring member can be arranged in a straight line, but it is difficult to arrange the door harness when the arrangement target part is bent
Solution Approach 1:
The base member is divided into a first base member and a second base member that can be bent relative to each other. This segmentation allows the wiring member arrangement path to adapt to bent surfaces while maintaining ease of arrangement in straight sections.
Solution Approach 2:
The second base member is configured to be bendable relative to the first base member, creating a dynamic structure that can adapt to different surface geometries. This dynamic capability enables the wiring member to be arranged on both straight and bent surfaces.
2Adaptability or versatility
If a fixed rigid structure is used to hold the wiring member, then the structure is simple and stable, but it cannot accommodate bended arrangements
Solution Approach 1:
The hinge part enables the second base member to be bent relative to the first base member, providing the necessary adaptability to hold wiring members in bended states while maintaining a relatively simple overall structure.
Solution Approach 2:
The hinge part is provided locally at specific positions where bending is needed, rather than making the entire structure complex. This localized approach provides the necessary adaptability while minimizing overall structural complexity.
3Adaptability or versatility
If additional holes are made in the door trim to arrange the wiring member, then the wiring can be routed through the bent parts, but it complicates the installation process
Solution Approach 1:
Instead of creating holes through the door trim (penetrating arrangement), the wiring member is arranged on the surface of the base member (surface arrangement). This dimensional change from through-hole to surface mounting simplifies installation while maintaining arrangement flexibility.
Solution Approach 2:
The base member with its hinge part acts as a flexible support structure that can conform to bent surfaces without requiring penetration into the door trim. This flexible surface arrangement eliminates the need for additional holes while maintaining adaptability.

AI summary
An object of the present disclosure is to provide a technique capable of holding a wiring member in a bended state. A wiring member integrated module includes: a wiring member, a first base member including an arrangement target part holding a part of the wiring member; and a second base member whose state can be changed from a first state where a part of the wiring member extending from the arrangement target part is held on an extension of the arrangement target part to a second state where the part is held in a bended state with respect to the arrangement target part.
