Wire Harness Assembly Structure for Stable Wire Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wire harness assemblies lack a structure to stably hold electric wires, leading to deformation of the wire arrangement shape and misalignment of connectors when the base and cover are integrated.
Innovation Solution
Incorporating a holding portion, such as a groove, into the base or cover of the assembly member to securely hold the electric wire, maintaining its arrangement shape and preventing movement between the base and cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the base and cover are integrated without a holding portion, then the assembly structure is simple, but the electric wire moves and the arrangement shape is deformed
Solution Approach 1:
The holding portion is formed on the base or cover in advance during manufacturing, creating a pre-prepared structure that guides and constrains the electric wire during assembly. This preliminary structural preparation prevents wire movement without requiring complex assembly procedures.
Solution Approach 2:
The holding portion acts as an intermediary element between the base/cover and the electric wire. It provides a mechanical interface that secures the wire in place while maintaining the simplicity of the overall assembly structure, resolving the contradiction between structural simplicity and wire stability.
2Ease of operation
If the electric wire is not held securely, then the assembly process is easy, but the connector alignment is poor and fitting is difficult
Solution Approach 1:
The holding portion is pre-formed on the base or cover during manufacturing, establishing the correct wire position before assembly. This preliminary positioning ensures that connectors align properly during the assembly process, achieving both ease of operation and manufacturing precision.
Solution Approach 2:
The holding portion structure enables the assembly member to self-position the electric wire correctly during assembly. The wire naturally settles into the holding portion, providing self-alignment functionality that ensures connector precision without requiring complex external positioning mechanisms.

AI summary
A wire harness assembly includes: a wire harness including an electric wire and a connector electrically connected to an end of the electric wire; and an assembly member in which the wire harness is arranged. The assembly member includes: a base; and a cover integrally provided on one surface side of the base. At least one of the base or the cover includes a holding portion configured to hold the electric wire.
