Sheet Wiring Member Retention Structure for Simple Harness Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire harness systems lack a simple and effective method for attaching regulation members, which is necessary for securing and routing wiring bodies efficiently.
Innovation Solution
A wiring member design that incorporates a sheet with a wire-like transmission member and a regulation member with a housing part and retaining piece, where the wiring body is bended to fit within the housing part and locked by the retaining piece, allowing for easy attachment and increased rigidity of the end portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a regulation member is attached to a wire harness, then the wiring body can be secured and routed efficiently, but the attachment process becomes complex and time-consuming
Solution Approach 1:
The patent combines the housing part and retaining piece into a single integrated regulation member. The housing part accommodates the wiring body while the retaining piece secures it, merging two functional elements into one component that simplifies the attachment process and reduces the number of parts needed.
Solution Approach 2:
The regulation member is divided into distinct functional segments: the housing part for accommodating the wiring body and the retaining piece for securing it. This segmentation allows each part to perform its specific function efficiently while maintaining overall simplicity of the attachment mechanism.
2Ease of operation
If the wiring body is bended to fit in the housing part, then the regulation member can be simply attached, but the wire-like transmission member may bend excessively
Solution Approach 1:
The patent applies local quality by providing the retaining piece at specific locations (tip end portions of sidewall parts) to secure the wiring body. This localized retention ensures that only necessary portions of the wiring body are constrained, allowing the wire-like transmission member to maintain its stability while enabling simple attachment through controlled bending.
3Reliability
If the retaining piece presses the end portion of the wiring body, then the attachment is secured, but the wiring body may be damaged or deformed
Solution Approach 1:
The retaining piece is designed to press the end portion of the wiring body in a controlled manner, creating a dynamic balance between securing the attachment and preserving the wiring body's integrity. The pressing force is applied locally at the end portion, providing reliable attachment while distributing stress to prevent damage to the overall wiring body structure.

AI summary
A wiring member includes: at least one wiring body including a sheet and a wire-like transmission member fixed to the sheet; and a regulation member including a housing part and a retaining piece and attached to the wiring body. The housing part includes a bottom part and two sidewall parts protruding from the bottom part. The wiring body is housed in the housing part while both end portions along a width direction are bended with respect to an intermediate portion and extend toward a tip end portion of each of the two sidewall parts. The retaining piece protrudes above the housing part from the tip end portion of each of the two sidewall parts to press the end portions of the wiring body.
