Vehicle Wire Harness Sheath with Molded Resin Branching

Solution Overview

Problem

Conventional vehicle wire harnesses face issues with increased cable length and potential contact with vehicle components when branching cables to multiple connection targets, leading to inefficient routing and increased man-hours for cable management.

Innovation Solution

A vehicle wire harness design featuring first to third cables connected to different connection targets, with a sheath covering all cables and a molded resin member that directs each cable in distinct directions, reducing cable length and preventing contact with vehicle components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If cables are branched to multiple connection targets using conventional methods, then the wire harness can connect to multiple electronic devices, but the cable length increases and cables may contact vehicle components

Engineering Contradiction:

Improveconnection capability to multiple electronic devicesVSAvoidcable length

Core Design Contradiction:

Adaptability or versatilityVSLength of moving object

Solution Approach 1:

The patent combines multiple cables and their routing paths into a single integrated sheath structure. The sheath houses all cables together and provides a unified protection and routing solution, preventing individual cables from contacting vehicle components while reducing overall cable length and improving routing efficiency.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The sheath serves multiple functions simultaneously: it protects individual cables, provides structured routing for multiple connection targets, prevents cable contact with vehicle components, and maintains organization throughout the wire harness system. This multi-functional design eliminates the need for separate protective measures for each cable.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If cables are branched to multiple connection targets using conventional methods, then the wire harness can connect to multiple electronic devices, but the number of cable clips increases and routing time increases

AI summary

A vehicle wire harness includes first to third cables to be respectively connected to different connection target objects, a sheath covering all the first to third cables together, and a molded resin member covering a portion of the sheath and a portion of each of the first to third cables. The first to third cables are led out of the molded resin member in different directions from each other.
