Solution Overview

Problem

Existing techniques are inadequate for protecting flat wiring members using protection sheet materials, as they are designed for round electrical wire bundles and fail to effectively prevent damage from burrs.

Innovation Solution

A flat wiring member is created by partially fixing a protection sheet material to the main surfaces of the wiring body at intervals, allowing relative movement and reducing the risk of damage from burrs, while also incorporating a sheet-like base material and wire-like transmission members for enhanced protection and flexibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a protection sheet material is fully fixed to the wiring body, then protection properties are improved, but the wiring body cannot relatively move when scraping against burrs, reducing effectiveness

Engineering Contradiction:
Improveprotection propertiesVSAvoidfixing structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The protection sheet material is divided into multiple fixed portions and unfixed portions, creating a segmented structure that allows different regions to serve different functions: fixed regions provide protection while unfixed regions allow relative movement when scraping against burrs

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of fully fixing the protection sheet material, only portions are fixed at intervals, allowing the sheet to partially move relative to the wiring body when needed, while still providing protection where fixed

Inventive Principle:
Principle #16Partial or excessive action

2Reliability

If a protection sheet material is applied to a flat wiring body, then protection is provided, but the technique for round wire bundles cannot be directly applied

Engineering Contradiction:
Improveprotection effectivenessVSAvoidapplication difficulty
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The protection sheet material is configured with different properties in different regions: fixed portions provide stable protection while unfixed portions allow movement, creating local variations in functionality suited to different operational conditions

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The protection sheet material transitions from a static fully-fixed structure to a dynamic structure where portions can move relative to the wiring body, adapting to scraping conditions while maintaining protection

Inventive Principle:
Principle #15Dynamics

AI summary

A wiring member includes a flat wiring body and a protection sheet material partially fixed to at least one main surface of the wiring body in a plurality of positions at intervals. For example, it is considered that the wiring body includes a sheet-like base material and a plurality of wire-like transmission members disposed on one main surface of the base material, and the protection sheet material is partially fixed to the other main surface of the base material.
