Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire harness routing structures in vehicles face reliability issues due to connector wear from vibrations and require complex installation processes, increasing the number of components and work procedures.
Innovation Solution
A wire harness routing member with continuous electric wires fixed to a base plate below the vehicle's floor panel, eliminating the need for connectors and through holes, and incorporating a power storage cover for electromagnetic shielding and reduced component count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connectors are used to connect wire harnesses at through holes in panels, then wire harness routing is achieved, but connection reliability deteriorates due to wear from vehicle vibrations
Solution Approach 1:
The patent removes connectors and through holes from the wire harness routing structure. Instead of connecting wire harnesses through panels using connectors, the wire harness is routed continuously through the passenger compartment without interruption, eliminating the connection points that are subject to wear from vibrations.
Solution Approach 2:
The patent integrates the wire harness routing path directly through the passenger compartment space, merging the routing function with the structural panels without requiring separate connector components. The wire harness passes through the compartment in a continuous manner, combining the routing and structural functions.
2Ease of manufacture
If through holes and connectors are installed in panels for wire harness routing, then wire connection is achieved, but the number of work procedures increases
Solution Approach 1:
The patent eliminates the need for drilling through holes and installing connectors in the panels. The wire harness is routed through the passenger compartment in a continuous manner, removing the time-consuming steps of hole drilling, connector installation, and sealing from the manufacturing process.
3Device complexity
If connectors and seal members are installed in through holes for wire harness routing, then wire protection and sealing are achieved, but the number of components increases
Solution Approach 1:
The patent removes connectors and seal members from the wire harness routing system. By routing the wire harness continuously through the passenger compartment without interruption, the system eliminates the need for these separate components, reducing both component count and potential failure points.
