Wiring Member Shape Maintaining Member Stiffness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing technique of sandwiching a wire harness with a single-sided adhesive sheet results in a lack of stiffness, causing the end side portion to hang down when the intermediate side portion is raised, which deteriorates assembling operability.
Innovation Solution
A wiring member with a sheet-like member and a wire-like transmission member, along with a shape maintaining member of higher stiffness that covers at least one side of the wiring body to maintain its shape, reducing the likelihood of hanging and improving assemblability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a single-sided adhesive sheet is used to sandwich the wire harness, then the wire harness can be externally mounted and retain its routing form, but the wire harness lacks stiffness and the end side portion significantly hangs down when the intermediate side portion is raised
Solution Approach 1:
The patent combines a flexible sheet-like member with a rigid shape maintaining member to create a composite structure. The sheet-like member provides flexibility for routing, while the shape maintaining member (made of rigid material such as resin or metal) provides the necessary stiffness to prevent hanging down. This composite approach resolves the contradiction by integrating both flexible and rigid properties in a single wiring member assembly.
2Ease of manufacture
If a single-sided adhesive sheet is used to sandwich the wire harness, then the wire harness can be externally mounted, but assembling operability deteriorates due to the hanging end side portion
Solution Approach 1:
By creating a composite structure with integrated shape maintaining properties, the wiring member maintains its routing form during assembly operations. The rigid shape maintaining member prevents the end side portion from hanging down, allowing assembly personnel to easily manipulate and position the wiring member without dealing with sagging or deformation, thus improving assembling operability while retaining external mounting capability.
3Device complexity
If no shape maintaining member is provided, then the wiring member structure remains simple, but the end side portion hangs down when the intermediate side portion is raised
Solution Approach 1:
The patent introduces a shape maintaining member made of rigid material to create a composite structure. This addition provides the necessary shape stability to prevent the end side portion from hanging down when the intermediate side portion is raised. The shape maintaining member is designed to be integrated with the sheet-like member, maintaining relative structural simplicity while achieving the required shape stability.

AI summary
The wiring member includes a wiring body and a shape maintaining member. The wiring body includes a sheet-like member and a wire-like transmission member fixed on the sheet-like member. The shape maintaining member is formed into a sheet-like shape having higher stiffness than the sheet-like member and covers at least one side of the wiring body along a front-back direction of the wiring body to maintain a shape of the wiring body.
