Wire Harness Router Clip Structure to Prevent Cable Slippage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for attaching a wiring harness to a vehicle component are inefficient, as they rely on cables being wrapped with tape and secured by cable ties, which can lead to slippage and require additional fastening means, complicating the routing and securing of cables.
Innovation Solution
A router clip with a holder, connecting section, and counter-holder design that creates two laterally open receiving spaces for cables, featuring toothing for enhanced engagement and adhesion, and a mold for producing the harness that allows easy cable insertion and secure embedding of the clip within a foam casing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cables are wrapped with tape and secured by cable ties, then the wiring harness can be attached to the vehicle component, but the attachment is prone to slippage and requires additional fastening means
Solution Approach 1:
The patent combines the holder and counter-holder into a single integrated router clip structure that simultaneously provides both support and fastening functions. The holder portion engages with the vehicle component while the counter-holder secures the cable arrangement, eliminating the need for separate cable ties and tape wrapping.
Solution Approach 2:
The router clip is divided into distinct functional portions: a holder portion for engaging the vehicle component, a connecting portion for structural linkage, and a counter-holder portion for securing the cable arrangement. This segmentation allows each portion to be optimized for its specific function while working together as a unified fastening system.
2Device complexity
If a simple holder design is used, then the device complexity is reduced, but the cable arrangement cannot be securely fastened to prevent slippage
Solution Approach 1:
The router clip incorporates elastic portions in both the holder and counter-holder that provide dynamic engagement. The holder portion has elasticity in a first direction to accommodate assembly variations, while the counter-holder has elasticity in a second direction to maintain continuous clamping force on the cable arrangement, preventing slippage under vibration and thermal expansion.
3Volume of moving object
If the holder and counter-holder are positioned close together, then the device size is reduced, but cables cannot be properly inserted into the receiving space
Solution Approach 1:
The router clip design positions the holder and counter-holder to define a receiving space that is accessible from multiple directions. The connecting portion is arranged to allow cable insertion from the side while maintaining a compact overall footprint, utilizing three-dimensional spatial arrangement to resolve the conflict between size and accessibility.
4Ease of operation
If the router clip uses elastic material for the holder and counter-holder, then the ease of assembly is improved, but the precision of cable positioning may be reduced
Solution Approach 1:
The router clip employs different material properties in different regions: the holder and counter-holder portions use elastic materials for easy assembly and accommodation of tolerances, while the connecting portion uses a more rigid material to maintain precise geometric relationships and positioning accuracy during operation.
