Branching Wiring Member Layout for Stable Folding Wire Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wire harness designs face issues with wire paths being disturbed or separating when folded, particularly at intersection points, leading to weakened holding forces and potential separation during packaging and transport.
Innovation Solution
A wiring member configuration where intersection locations of linear transmission members are restricted to branching portions, with specific branching and alignment sequences, and optionally covered by additional sheets to prevent disturbance and separation during folding.

Engineering Contradiction Analysis
1Volume of moving object
If the wire harness is folded during packaging or transport, then compact form is achieved, but the paths of the wires may be disturbed and separation may occur at the wire intersection portion
Solution Approach 1:
The wire harness is divided into modular units with standardized intersection portions that can be folded independently. Each intersection portion is designed as a separate functional unit with specific folding characteristics, allowing the overall harness to be compacted without compromising wire path integrity at critical junctions.
Solution Approach 2:
The wires are pre-positioned and fixed at intersection portions before folding occurs. The intersection portions are prepared in advance with proper wire routing and securing mechanisms, so that when folding happens during packaging, the wires maintain their correct paths and connections without disturbance or separation.
2Adaptability or versatility
If wires are disposed intersecting to span over other wires on the sheet-shaped functional outer covering member, then routing flexibility is improved, but the holding force weakens at the wire intersection portion
Solution Approach 1:
Different regions of the wire harness are designed with different properties. At intersection portions, the structure is reinforced with enhanced holding mechanisms, while other regions maintain flexibility for routing. This local differentiation allows wires to span over each other for routing flexibility while ensuring strong holding force at critical intersection points through localized structural enhancements.

AI summary
The present invention aims to suppress a case in which paths of linear transmission members are disturbed on a sheet-shaped member or linear transmission members separate from a sheet-shaped member when a wiring member obtained by fixing linear transmission members on a sheet-shaped member is folded. The wiring member includes a sheet-shaped member and multiple linear transmission members that are fixed on the sheet-shaped member. The plurality of linear transmission members are fixed on the sheet-shaped member such that a portion of the plurality of linear transmission members branches with respect to another said linear transmission member at a branching portion. An intersection location of the plurality of linear transmission members is located at only the branching portion.
