Wire Harness Guide With Channel And Bend
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for attaching wire harnesses to components, such as panels in complex machinery and motor vehicles, lack precision and require complex steps, leading to imprecise placement and increased tolerance in the distance of wire harness extension.
Innovation Solution
A wire harness guide featuring an elongated bracket with a channel and transverse bend for accurate placement, combined with an adhesive attachment tab, allows for a predefined wire harness extension and protection from adjacent surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If adhesive methods (tape, glue) are used to attach wire harness to panel, then attachment is achieved, but placement precision is poor and tolerance for extension distance is large
Solution Approach 1:
The patent introduces a wire harness guide as an intermediary component between the wire harness and the panel. This guide includes a channel that receives the wire harness and positioning features (such as tabs or protrusions) that align with corresponding features on the panel, enabling precise placement without relying solely on adhesive methods.
Solution Approach 2:
The wire harness guide is pre-formed with specific geometric features including channels, tabs, and positioning elements during manufacturing. These pre-configured features enable accurate alignment and placement when the guide is installed on the panel, eliminating the need for complex assembly steps during installation.
2Manufacturing precision
If zip ties, brackets, or hook-and-loop fasteners are used to attach wire harness, then attachment is achieved, but proper and accurate placement is imprecise and requires tooling
Solution Approach 1:
The wire harness guide serves as a mediator that combines both positioning and attachment functions. The guide includes positioning features (tabs, protrusions, or alignment elements) that ensure accurate placement, and attachment features (adhesive backing, mechanical fastening elements, or snap-fit components) that enable simple installation without requiring additional tooling.
Solution Approach 2:
The patent merges multiple functions into a single integrated wire harness guide component: positioning (through geometric alignment features), protection (through the channel structure), and attachment (through integrated fastening mechanisms). This consolidation eliminates the need for separate positioning tools and attachment devices, simplifying the installation process.
3Manufacturing precision
If wire harness is routed without guidance, then installation is simple, but accurate positioning relative to panel and component is not achieved
Solution Approach 1:
The wire harness guide incorporates localized geometric features at specific positions: channels at the wire harness interface for reception and alignment, tabs or protrusions at the panel interface for positioning, and protective flanges at areas requiring protection. These locally optimized features provide precise positioning without requiring complex overall structure.
Solution Approach 2:
The guide may incorporate flexible or thin-walled structures that can be easily formed during manufacturing and installed without requiring significant force or complex tooling. The channel portion and flanges can be designed with appropriate wall thicknesses to provide structural integrity while maintaining ease of installation.

AI summary
A wire harness guide for accurate placement of a wire harness onto a component and protection of the wire harness from rubbing against a surface in near proximity thereof is provided. The wire harness guide can include an elongated bracket having a channel portion extending along a length of the bracket, the channel portion located between an upper flange and a lower flange. The upper flange can extend along at least a portion of the elongated bracket, as can the lower flange. A side wall can extend between the upper flange and the lower flange and a bend extending transversely across the elongated bracket can be present.
