Wire Harness with Integrated Soundproofing Sheets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wire harnesses in vehicles face challenges in easy mounting and soundproofing, particularly in preventing wire contact with interior panels, which can generate noise and require complex fixation processes.
Innovation Solution
A wire harness design incorporating two soundproofing sheets with holes indicating the wire's position, combined with binders that secure the wire and soundproofing sheets, facilitating easy mounting and soundproofing while protecting the wire from noise-induced contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wire protection member is added to protect the wire from contact with surrounding members, then the wire is protected from breakage, but the device complexity increases
Solution Approach 1:
The patent combines the wire protection function and soundproofing function into a single integrated component. The soundproofing material serves dual purposes: it provides acoustic insulation for the interior panel and simultaneously protects the wire from contact with surrounding members. This merging eliminates the need for separate wire protection members, reducing device complexity while maintaining reliability.
Solution Approach 2:
The soundproofing material is designed to perform multiple functions simultaneously. It acts as both a soundproofing layer for the interior panel and a protective covering for the wire. This multi-functionality approach allows a single component to address both wire protection and acoustic insulation requirements, simplifying the overall structure.
2Ease of manufacture
If separate mounting processes are used for wire harness and soundproofing material, then each component can be optimized independently, but the ease of operation deteriorates due to complex fixation processes
Solution Approach 1:
The wire harness and soundproofing material are integrated into a single assembly that is mounted together as one unit. The soundproofing material is positioned to cover the wire along its entire route, and both are fixed to the interior panel simultaneously using a single mounting process. This eliminates the need for separate fixation operations, significantly improving ease of operation during installation.
3Reliability
If the wire route is not clearly identifiable on the soundproofing material, then the soundproofing material provides complete coverage, but the ease of operation worsens due to difficulty in identifying wire position
Solution Approach 1:
The patent incorporates visual indicators (such as colored markings or contrasting patterns) on the soundproofing material at locations corresponding to the wire route. These visual cues allow installers to easily identify the wire position beneath the soundproofing material without compromising the material's protective or soundproofing functions. The markings are strategically placed to guide proper installation while maintaining complete coverage.

AI summary
An object is to provide a wire harness capable of protecting a wire, and also capable of facilitating the mounting of the wire and a soundproofing material to a place where soundproofing (e.g., sound absorption or sound insulation) is required. The wire harness includes a wire and a soundproofing sheet. The soundproofing sheet includes a sheet-like soundproofing material that is combined integrally with the wire along the wire. A plurality of holes are formed in the soundproofing sheet at positions along a route of the wire.
