Partially Cylindrical Wire Harness Support for Flat Bar Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire harness support systems are not suitable for supporting wire harnesses with a flat configuration on bar-shaped members, as they are designed primarily for round cross-sections.
Innovation Solution
A support member-attached wire harness system featuring a partially cylindrical fitting portion and support portions such as locking projections, recesses, and connector locking portions to securely fasten the wire harness to a bar-shaped member, ensuring stability and flat positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wire harness support member with a protective portion covering the wire harness is used, then the wire harness is protected and held, but it is not suitable for supporting the wire harness flatly
Solution Approach 1:
The support portion is provided at specific locations (both end sides in the circumferential direction) rather than uniformly across the entire support member. This localized support structure allows the wire harness to be held in a flat state at critical positions while maintaining the overall protective function, resolving the contradiction between protection and flat positioning capability
Solution Approach 2:
The support member is divided into distinct functional portions: a fitting portion for mounting on the bar-shaped member and support portions at the ends for holding the wire harness. This segmentation allows each portion to be optimized for its specific function, enabling both protection and flat positioning simultaneously
2Ease of manufacture
If the wire harness is supported without pre-fixing electrical wires to the sheet material, then installation is easier and more flexible, but positioning precision and stability may be compromised
Solution Approach 1:
The support portion structure enables the wire harness to self-position and self-stabilize when installed on the bar-shaped member. The geometric constraints of the support portions automatically maintain the flat state of the wire harness without requiring pre-fixing operations, achieving both installation ease and positioning precision
Solution Approach 2:
The support portions are pre-configured with specific geometries that inherently guide and constrain the wire harness into the correct flat position during installation. This preliminary structural design ensures positioning precision is achieved automatically during the installation process, eliminating the need for pre-fixing while maintaining accuracy

AI summary
A support member-attached wire harness includes a wire harness including an electrical wire and a support member that includes a fitting portion formed in a partially cylindrical shape that is opened partially in a circumferential direction so as to be capable of being fitted to an outer peripheral portion of a bar-shaped member. On at least one of the wire harness and the support member, a support portion for supporting the wire harness disposed along an outer periphery of the fitting portion at a fixed position with respect to the fitting portion is formed.
