Conductive Path Protection Structure with Nested Identifiers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing conductive path protection structures for vehicle wire harnesses require costly color-coded protectors to differentiate high-voltage and low-voltage electric wires, leading to increased costs and susceptibility to damage due to inadequate protection at visual hole positions.
Innovation Solution
A conductive path protection structure featuring a first protector with an identification mark on its surface and a second protector with openings along the insertion path, allowing visual confirmation of the wire specification without additional markings on the second protector, while ensuring the entire conductive path is protected by the first protector, thus reducing costs and preventing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If color-coded protectors are used to differentiate high-voltage and low-voltage electric wires, then identification of wire specifications is improved, but manufacturing cost increases
Solution Approach 1:
The patent uses a visual hole as a simple copy or indicator that reveals the identification mark on the inner protector through the outer protector. This allows specification identification without requiring the outer protector itself to be color-coded, thereby reducing manufacturing complexity and cost while maintaining clear visual identification of wire specifications
Solution Approach 2:
The patent applies identification marks with different colors directly on the protectors to indicate wire specifications. The visual hole system allows these colored marks to be visible through the outer protector, providing clear specification differentiation without requiring the entire outer protector to be color-coded, thus reducing manufacturing cost
2Loss of information
If visual holes are provided in protectors for identification, then specification identification is improved, but protection reliability deteriorates due to exposed positions
Solution Approach 1:
The patent employs a nested structure where the inner protector contains the conductive path and the outer protector contains the inner protector. The visual hole is formed only in the outer protector, allowing identification marks on the inner protector to be visible through the outer protector while maintaining continuous protection of the conductive path by the inner protector without any exposure
Solution Approach 2:
The outer protector acts as an intermediary that provides the visual hole for identification purposes while the inner protector maintains continuous protection of the conductive path. The identification mark on the inner protector is made visible through the outer protector's visual hole, allowing specification identification without compromising the protective function
3Loss of information
If separate protectors are used for high-voltage and low-voltage wires, then identification is improved, but device complexity increases
Solution Approach 1:
The outer protector is designed as a universal component that can accommodate both high-voltage and low-voltage inner protectors. The visual hole in the outer protector allows identification marks on any inner protector to be visible, eliminating the need for different outer protector designs for different voltage levels and thereby reducing device complexity

AI summary
A conductive path protection structure includes a first protector configured to accommodate a conductive path therein and to protect the conductive path, and a second protector configured to accommodate the first protector therein. An identification mark for identifying a specification of the conductive path is provided on a peripheral surface of the first protector. The second protector is formed with an opening configured to expose the identification mark therethrough to an outside of the second protector.
