Electric Storage Device Wire Harness Gap Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing size of wire harnesses in electric vehicles due to enhanced vehicle performance and growing occupant comfort demands, coupled with limited interior spaces, necessitates a reduction in the overall size of electric storage devices, including wire harnesses.
Innovation Solution
The electric storage device configuration includes an electric storage module with a bracket-mounted electric junction box and wire harnesses disposed in a gap defined by imaginary planes extending from the module's peripheral surfaces, allowing for reduced device size and improved work efficiency through connector fitting and routing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wire harnesses are increased in size to meet enhanced vehicle performance and occupant comfort demands, then vehicle performance and comfort are improved, but the overall size of electric storage devices increases and interior space is consumed
Solution Approach 1:
The wire harness is nested within the gap between the electric storage module and the electric junction box. The connector is received by the connector receiving portion formed in the electric junction box, creating a nested arrangement where the wire harness and connector are accommodated within the existing structural gap rather than occupying additional space.
Solution Approach 2:
The wire harness is routed through the gap dimension between the electric storage module and electric junction box, utilizing the vertical or lateral space between components rather than extending horizontally. This dimensional repositioning reduces the overall footprint of the electric storage device while maintaining necessary wire harness length for electrical connections.
2Adaptability or versatility
If wire harnesses are increased in size to accommodate more connections, then electrical connectivity is improved, but the complexity of routing and positioning wire harnesses increases
Solution Approach 1:
The connector receiving portion is pre-formed in the electric junction box at the appropriate position and orientation. This preliminary preparation of the receiving structure guides the wire harness routing process and simplifies assembly by providing a predetermined path and destination for the wire harness and connector.
Solution Approach 2:
The gap between the electric storage module and electric junction box serves as an intermediary space that facilitates wire harness routing. This intermediate region provides a natural channel for the wire harness to connect the two components, reducing routing complexity by utilizing the existing spatial relationship between mounted components.
3Volume of moving object
If the electric junction box is mounted close to the electric storage module, then device compactness is improved, but wire harness routing space is reduced
Solution Approach 1:
The connector receiving portion is locally formed in the electric junction box at a specific position that optimizes both compactness and routing ease. This localized structural feature provides a dedicated receiving space that accommodates the connector while maintaining the overall compact arrangement of the electric storage device.
Solution Approach 2:
The connector is nested within the connector receiving portion of the electric junction box, allowing the wire harness to be accommodated within the existing structural gap. This nested arrangement enables close mounting of the electric junction box to the electric storage module while still providing adequate space for wire harness routing and connection.

AI summary
An electric storage device includes an electric storage module, a bracket, an electric junction box, and a wire harness. The electric storage module includes electric storage components. The electric storage module includes an end surface and peripheral surfaces perpendicular to the end surface. The bracket is mounted to the electric storage module and includes a first surface opposed to the end surface of the electric storage module and a second surface opposite from the first surface. The electric junction box is mounted to the bracket to be opposed to the second surface of the bracket with a gap between the electric junction box and the second surface of the bracket. The wire harness is connected to the electric storage module and disposed in a section of the gap in which the end surface of the electric storage module is opposed to the electric junction box.
