Vehicle Wire Harness Standardized Trunk Line Simplification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire harnesses for vehicles have complex wiring paths that are not optimized for simplification across different vehicle types, leading to increased complexity and reduced versatility.
Innovation Solution
A wire harness design featuring a standardized linear trunk line section with bundled power and communication lines, distributors connected to both ends, and a ground plate buried in the resin flooring, allowing for simplified wiring and improved versatility by standardizing the trunk line and varying the middle wiring bodies based on vehicle type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wire harness is designed to be applicable to multiple vehicle types (right-hand drive, left-hand drive, sedan, van), then versatility is improved, but wiring path complexity increases
Solution Approach 1:
The wire harness is divided into a standardized trunk line section and vehicle-specific middle wiring bodies. The trunk line section includes a common power supply line and communication line that remain identical across all vehicle types, while the middle wiring bodies are customized for each vehicle configuration. This segmentation allows the complex wiring to be broken down into manageable, standardized modules.
Solution Approach 2:
The trunk line section is designed as a universal component that can be applied to all vehicle types (right-hand drive, left-hand drive, sedan, van). By creating a common standardized section that performs the same power supply and communication functions across different vehicle configurations, the patent achieves versatility without requiring complete customization of the entire wire harness.
2Ease of manufacture
If the connection part between front harness and integrated harness is arranged on the same side (left or right), then ease of assembly is improved, but adaptability to different vehicle types deteriorates
Solution Approach 1:
The connection part position is made configurable rather than fixed. The system allows the connection part between the front harness and integrated harness to be arranged on different sides (left or right) depending on the vehicle type, while maintaining the same standardized trunk line section. This dynamic positioning capability enables easy assembly for each specific vehicle configuration without sacrificing adaptability.

AI summary
A wire harness includes a trunk line section including a power line for power supply as a wiring body wired in a vehicle, a distributor that is connected to the trunk line section and distributes electric power from a power supply mounted on the vehicle to an appliance to be connected, and a ground plate for grounding buried in a resin flooring material of the vehicle separately from the trunk line section. Thus, with the wire harness, a wiring path can be simplified by combining the trunk line section, the distributor, and the ground plate.
