Wiring Member Temporary Joint for Bending Form Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire harnesses with sheet-like functional exterior members face difficulties in maintaining a compact bending form during packing and transportation, as tape winding methods make it troublesome to detach and develop the harness.
Innovation Solution
A wiring member with a temporary joint part that joins overlapping portions of a wire-like transmission member and a base member, allowing for easy separation and maintaining the bending form, using adhesive or direct fixing methods to resolve the joint state with less force than required for holding the sheet and wire transmission member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If tape winding is used to maintain the bending form of the wire harness, then the compact form is maintained, but it becomes troublesome to detach the tape and develop the harness
Solution Approach 1:
The jointing member is divided into multiple pressing parts that can independently press different portions of the wiring body. Each pressing part can be detached separately, allowing selective development of different sections without requiring complete detachment of the entire tape winding structure.
Solution Approach 2:
The jointing member transitions from a static tape winding to a dynamic structure with multiple detachable pressing parts. The pressing parts can be selectively detached and reattached, providing flexible control over the bending form maintenance and development operations.
2Stability of the object's composition
If strong adhesion is used to maintain the bending form, then the bending state is maintained, but it requires excessive force to resolve the joint state for development
Solution Approach 1:
Different pressing parts of the jointing member have different pressing forces applied to different portions of the wiring body. The pressing force is distributed locally rather than uniformly applied, allowing the bending form to be maintained with optimized force distribution that reduces the total force required for detachment.
Solution Approach 2:
The jointing member applies pressing force only to the necessary portions of the wiring body required to maintain the bending form, rather than applying excessive force across the entire structure. This partial action maintains stability while minimizing the force required for later detachment.
3Volume of moving object
If the wiring body is bent for compact packing, then the packing efficiency is improved, but the wiring body may deform during transportation
Solution Approach 1:
The jointing member is positioned and attached to the wiring body in advance before transportation, establishing the desired bending form and compact configuration. This preliminary action ensures that the wiring body maintains its shape throughout transportation without requiring additional support structures.
Solution Approach 2:
The jointing member acts as an intermediary element between the wiring body and the external environment during transportation. It mediates the mechanical stresses and forces applied to the bent wiring body, preventing deformation while maintaining the compact packing configuration.
Applied Scientific Principles

Function Achieved in This Case
Enables easy development of the wiring member while maintaining its bending form, suppressing debonding of the wire transmission member from the sheet and cover, and allowing for efficient deployment without re-adhesion issues.

AI summary
A wiring body includes a wire-like transmission member and a base member to which the wire-like transmission member is fixed. A temporary joint part joins portions where a first part and a second part mutually extending in an opposite side from a bending position in the wiring body overlap with each other in a state where the wiring body is bended in an intermediate portion of the wire-like transmission member in an extension direction to maintain a bending state of the wiring body. The temporary joint part is formed to be able to resolve a state of joining the first part and the second part by a relative separation movement of the first part and the second part.
