Flat Harness Attachment Structure for Variable Width Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flat harness attachment structures are not capable of accommodating flat harnesses of varying widths, limiting their attachment flexibility to attachment target portions.
Innovation Solution
A flat harness attachment structure comprising a fixing portion and a pressing portion, where the pressing portion extends from the fixing portion to securely press the flat harness against the attachment target surface, regardless of the harness's width, allowing for the attachment of flat harnesses of varying widths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a clip with a pair of fixing claws is used to attach the flat wiring member, then the flat wiring member can be fixed to the panel, but the structure cannot accommodate flat harnesses of varying widths
Solution Approach 1:
The pressing portion is designed to be elastically deformable, allowing it to dynamically adapt to different flat harness widths. When the pressing portion presses the flat harness against the panel, it elastically deforms to accommodate various widths while maintaining reliable attachment. This dynamic property resolves the contradiction between fixed-structure reliability and width adaptability.
Solution Approach 2:
The pressing portion's width is made variable through elastic deformation, allowing the attachment structure to change its dimensional parameter (width) based on the flat harness being attached. This parameter change enables the same attachment structure to reliably secure flat harnesses of different widths.
2Device complexity
If a fixed-width clip structure is used, then the attachment structure is simple, but it cannot attach flat harnesses of different widths
Solution Approach 1:
Instead of creating multiple fixed-width clips for different harness sizes, the invention uses a single clip structure with a pressing portion that can elastically deform to match different widths. This dynamic adaptation maintains structural simplicity while achieving width versatility.
3Stability of the object's composition
If the pressing portion is made rigid, then the attachment structure is stable, but it cannot adapt to varying flat harness widths
Solution Approach 1:
The pressing portion is designed with elastic deformability, allowing it to dynamically adjust its width to match different flat harness sizes while maintaining stable attachment. The elastic property enables both adaptability during attachment and stability during operation.
Solution Approach 2:
The pressing portion's width parameter is made changeable through elastic deformation, allowing the structure to adapt to different flat harness widths while maintaining stable attachment force. The material's elastic properties enable parameter adjustment without sacrificing attachment stability.

AI summary
An object of the invention is to be able to attach flat harnesses of varying widths to an attachment target portion. A flat harness attachment structure to be attached to an attachment target member having an attachment target surface includes: a flat harness to be installed on the attachment target surface; a fixing portion to be fixed to the attachment target member on one side portion side of the flat harness; and a pressing portion extending from the fixing portion over the flat harness so as to press the flat harness against the attachment target surface.
