Foldable Wiring Member Layout for Stable Wire Intersections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wire harnesses face issues with wire paths being disturbed or separating when folded, particularly at intersection points, leading to potential weakening of the holding force and risk of separation during packaging and transport.
Innovation Solution
A wiring member design where linear transmission members are fixed on a sheet-shaped member such that their intersection points are located away from folding positions, and path bending portions are positioned to avoid folding locations, ensuring stability and preventing separation during packaging and transport.

If the wire harness is folded to achieve compact packaging, then the packaging efficiency is improved, but the wire paths may be disturbed or separation may occur at intersection portions
Solution Approach 1:
The patent applies preliminary action by pre-positioning wire intersection portions away from folding lines before packaging occurs. The wire harness is designed with predetermined intersection locations that are strategically placed in regions that will not be subjected to folding stress, thereby preventing path disturbance and separation before the actual folding action takes place.
Solution Approach 2:
The patent applies local quality by creating different functional zones within the wire harness structure. Specific regions are designated as folding zones (where folding occurs) and non-folding zones (where wire intersections are located). This spatial differentiation ensures that critical wire intersection portions are protected from folding stress while allowing the overall harness to be compacted effectively.
2Productivity
If wires are positioned to span over other wires for routing efficiency, then the routing efficiency is improved, but the holding force weakens at intersection portions
Solution Approach 1:
The patent applies the intermediary principle by introducing a sheet member as a mediating structure between wires at intersection portions. The sheet member provides additional support and distributes mechanical stress, preventing direct wire-to-wire contact that would weaken holding force. This intermediary structure allows wires to maintain their spanning configuration for routing efficiency while the sheet member reinforces the intersection areas.
Solution Approach 2:
The patent applies composite materials by combining the wire harness with a sheet member to create a composite structure. The sheet member, made from materials with appropriate mechanical properties, reinforces the wire intersections and provides enhanced holding force. This composite construction maintains the spanning configuration of wires for efficient routing while adding structural strength at critical intersection points.

AI summary
A wiring member includes a sheet-shaped member and multiple linear transmission members that are fixed on the sheet-shaped member. The multiple linear transmission members are fixed on the sheet-shaped member such that a portion of the multiple linear transmission members intersects with respect to another said linear transmission member. An intersection location of the multiple linear transmission members is located away from a folding position.
