Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The existing wire harnesses with sheet-shaped functional outer covering members are prone to wire path disturbances and separation when folded, particularly at intersection points, leading to weakened holding forces and potential separation during packaging and transport.

Innovation Solution

A wiring member design that includes a sheet-shaped member with linear transmission members intersecting away from folding tracks, optionally with a vehicle fixing portion, intersection locations near the end of the sheet, and rigidity providing members at these intersections to prevent disturbances and separation during folding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the wire harness is folded to achieve compact packaging, then the packaging efficiency is improved, but the wire paths may be disturbed and separation may occur at intersection portions

Engineering Contradiction:

Improvepackaging volumeVSAvoidwire path stability

Core Design Contradiction:

Volume of moving objectVSReliability

Solution Approach 1:

The patent applies preliminary action by pre-positioning wire intersections away from folding tracks before packaging occurs. The wire harness is designed with predetermined intersection locations that are deliberately placed in regions that will not be subjected to folding during packaging, transport, or storage, thereby preventing wire path disturbance and separation before they can occur.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent applies local quality by creating different functional zones on the sheet-shaped functional outer covering member. Specifically, certain regions are designated as folding tracks for packaging while other regions are designated as wire intersection zones that remain protected from folding. This spatial differentiation ensures that wire intersections occur only in stable, non-folding areas.

Inventive Principle:

Principle #3Local quality

2Area of stationary object

If wires are arranged to intersect on the sheet-shaped functional outer covering member to achieve compact layout, then the space utilization is improved, but the holding force weakens at intersection portions making them prone to separation

Engineering Contradiction:

Improvesheet member area utilizationVSAvoidholding force at intersection

Core Design Contradiction:

Area of stationary objectVSStrength

Solution Approach 1:

The patent applies local quality by designating specific regions of the sheet-shaped functional outer covering member as wire intersection zones with enhanced protective characteristics. These localized regions are positioned away from folding tracks and are specifically intended to accommodate wire intersections while maintaining adequate holding force through their protected location and potential reinforcement structures.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent applies the intermediary principle by introducing the sheet-shaped functional outer covering member as a mediator between the wires and the folding operation. This intermediate structure provides a stable substrate that supports wire intersections away from direct folding stress, thereby protecting the wire holding force while still allowing compact packaging when folded along predetermined tracks.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Volume of moving object

If the functional outer covering member is folded at wire intersection portions to achieve compact form, then the packaging compactness is improved, but wire path disturbance and separation occur

Engineering Contradiction:

Improvepackaging volumeVSAvoidwire path integrity

Core Design Contradiction:

Volume of moving objectVSEase of operation

Solution Approach 1:

The patent applies preliminary action by pre-planning and pre-positioning wire intersections away from folding tracks in the design phase. This preliminary arrangement ensures that when folding occurs during packaging, the wire intersections are already in safe zones that will not be disturbed, thereby maintaining wire path integrity without requiring additional protective measures during the folding operation.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent applies local quality by creating distinct functional zones on the sheet-shaped functional outer covering member: folding tracks for packaging and wire intersection zones for electrical connections. This spatial differentiation ensures that folding operations are confined to specific regions that do not interfere with wire intersections, thereby maintaining wire path integrity while achieving packaging compactness.

Inventive Principle:

Principle #3Local quality

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 the linear transmission members separate from the sheet-shaped member. The 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 track.
