Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods for preventing wire harness interference with vehicle body panels are cumbersome due to the need for complex distance adjustments.

Innovation Solution

A bracket is attached to a metal panel forming a housing chamber, featuring a first surface attached to the panel and a second surface that contacts the wire harness to prevent interference, made of resin to reduce friction, and includes notch and receiving surfaces to support the harness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If distance adjustment settings are used to prevent wire harness contact with panel, then contact prevention is achieved, but configuration complexity increases

Engineering Contradiction:

Improvecontact preventionVSAvoidconfiguration complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

A bracket is introduced as an intermediary component between the wire harness and the panel. The bracket includes a first surface attached to the panel and a second surface that contacts the wire harness, creating a physical barrier that prevents direct contact. This mediator approach eliminates the need for complex distance adjustment settings while maintaining reliable contact prevention.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The protection function is segmented into a separate bracket component rather than being integrated into the panel or wire harness themselves. This segmentation allows the bracket to be independently designed and installed, providing a simple solution without complicating the overall system configuration.

Inventive Principle:

Principle #1Segmentation

2Reliability

If complex distance adjustment mechanism is implemented, then contact prevention is improved, but ease of operation deteriorates

Engineering Contradiction:

Improvecontact preventionVSAvoidinstallation simplicity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The bracket serves as a pre-configured intermediary that provides fixed spacing between the wire harness and panel. By attaching the bracket to the panel and allowing the wire harness to contact the bracket's second surface, the system achieves reliable contact prevention without requiring complex adjustment mechanisms or difficult installation procedures.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Device complexity

If wire harness is allowed to contact panel directly, then configuration is simple, but damage risk increases

Engineering Contradiction:

Improveconfiguration simplicityVSAvoiddamage risk

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The bracket provides beforehand cushioning by positioning its second surface between the wire harness and the panel. When vibration occurs, the wire harness contacts the bracket first, which absorbs and distributes the impact forces, preventing direct contact with the panel and reducing damage risk while maintaining a simple configuration.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

AI summary

A bracket (14) includes a first surface (18) and a second surface (19). The first surface (18) is to be attached to a metal panel (2) that forms at least a portion of a housing chamber (3) that accommodates a vibration source (4). The second surface (19) is positioned on the opposite side to the first surface (18), and comes into contact with a wire harness (8) routed inside the housing chamber (3), in order to guard the panel (2) from contact with the wire harness (8) when the wire harness (8) receives vibration of the vibration source (4).
