Wire Harness Branch Support Structure for Easier Vehicle Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing assembly process for flat wiring members, such as wire harnesses, is complex and requires a more simplified operation for easier integration into vehicles.
Innovation Solution
A wiring member design featuring a main wire part and branch wire part, with a sheet material that includes a main wire fixing part and a branch wire fixing part, where the branch wire support part is integrated to provide higher rigidity and can be bent or deformed for easier handling and assembly, potentially being magnetic for attraction during transport.

Engineering Contradiction Analysis
1Ease of operation
If a flat wiring member (wire harness) is assembled to a vehicle using conventional methods, then the wiring member can be installed, but the assembly operation becomes complex and difficult
Solution Approach 1:
The wiring member is segmented into a main body portion and multiple protruding portions, each serving specific functions. The protruding portions are further divided into first and second protruding portions with different configurations, allowing modular assembly and simplifying the overall installation process to basic alignment and engagement actions.
Solution Approach 2:
The first and second protruding portions act as intermediary elements that facilitate the connection between the wiring member and the vehicle body. These protrusions provide intermediate alignment and positioning functions, mediating the complex assembly operation into simple insert-and-lock actions.
2Ease of operation
If the branch wire part is made flexible for handling, then it can be easily manipulated, but it bends during transport and assembly causing positioning errors
Solution Approach 1:
The wiring member exhibits different mechanical properties in different regions. The main body portion maintains a standard configuration for stability, while the protruding portions are designed with specific geometries (first protrusion with larger dimensions, second protrusion with smaller dimensions) to provide localized support and maintain orientation without compromising overall flexibility during assembly.
Solution Approach 2:
The protruding portions are pre-formed during manufacturing with specific orientations and dimensions. This preliminary shaping ensures that during transport and assembly, the wiring member naturally maintains its intended configuration, preventing bending-induced positioning errors before assembly begins.

AI summary
A wiring member includes: a plurality of wire-like transmission members wired in a form including a main wire part and a branch wire part; and a sheet material including a main wire fixing part to which the main wire part is fixed and a branch wire fixing part to which the branch wire part is fixed, wherein the branch wire fixing part is branched from the main wire fixing part, a branch wire support part is provided in the branch wire fixing part, and the branch wire support part extends along a longitudinal direction of the branch wire part, and is formed to have higher rigidity than each of the wire-like transmission members constituting the branch wire part.
