Wire Harness Path Control via Movable and Fixing Supports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing techniques for controlling the path of electric lines in vehicles are complex due to the cumbersome connection methods between corrugated tubes and path control members, which require multiple holding portions and bolts, making installation and design changes difficult.
Innovation Solution
A wire harness system that includes a corrugated tube with annular ridges and valleys, a path control member shaped to conform to the electric line path, and a support system with movable and fixing supports that allow easy connection and positioning of the path control member relative to the corrugated tube, enabling flexible installation and design adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a corrugated tube-equipped electric line and a bone member are connected by sandwiching them between a pair of holding portions and fastening with bolts, then the path control is achieved, but the connection operation becomes complex
Solution Approach 1:
The support is divided into a first support portion that engages with the bone member and a second support portion that engages with the corrugated tube. This segmentation allows each portion to be optimized for its specific function and enables easier assembly by allowing the path control member to be positioned between the two support portions independently before final attachment
Solution Approach 2:
The support acts as an intermediary component between the bone member and the corrugated tube. Instead of directly connecting these two components with multiple holding portions and bolts, the support provides a simplified interface that facilitates easier attachment while maintaining reliable path control
2Reliability
If multiple holding portions and bolts are used to connect path control members, then secure attachment is achieved, but the number of parts and assembly complexity increases
Solution Approach 1:
The first support portion and the second support portion are merged into a single integrated support component. This merging reduces the total number of parts needed for connection while maintaining secure attachment, as the support simultaneously engages with both the bone member and the corrugated tube through its different portions
Solution Approach 2:
The support serves multiple functions: it provides structural connection between the bone member and corrugated tube, maintains the positional relationship of these components, and enables easy attachment through its designed engagement features. This multi-functionality reduces the need for separate specialized components

AI summary
A wire harness that includes an electric line; a corrugated tube that includes annular ridges and annular valleys alternately formed along an extension direction, and that covers the electric line; a path control that is arranged in at least one section that extends in the extension direction of the electric line so as to be parallel to the corrugated tube, and that is shaped so as to conform to a path along which the electric line is arranged in the section and to control the path in the section; and a support that includes a first support that supports the path control and a second support that is fitted into the annular valleys of the corrugated tube so as to support the corrugated tube, the support being configured to connect the path control to the corrugated tube.
