Vehicle Battery Mounting Structure With Recessed Wire Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle mounting structures for power storage devices, such as battery systems, result in a large vertical height dimension due to vertical stacking, compressing the passenger compartment and reducing interior space.
Innovation Solution
A vehicle mounting structure where the power storage device is assembled under the vehicle frame with a protrusion that fits into a recess, and electrical wires are routed flat within the device, eliminating the need for exterior protective members and optimizing space usage by routing large-diameter wires in previously wasted space between modules and a cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the power storage device is vertically stacked under the vehicle frame, then the power storage capacity can be maintained, but the vertical height dimension becomes large, compressing the passenger compartment
Solution Approach 1:
The patent repositions the power storage device from a vertical stacking arrangement to a horizontal placement arrangement under the vehicle frame. The protrusion on the power storage device fits into a recess in the vehicle frame, allowing the device to be positioned at the same height level as the frame rather than stacked vertically below it. This dimensional reconfiguration reduces the vertical height occupation while maintaining the power storage capacity through optimized horizontal space utilization.
2Reliability
If electrical wires are routed between the floor panel and vehicle frame with exterior protective members, then the wires are protected, but the vertical height dimension increases and assembly complexity increases
Solution Approach 1:
The patent integrates the electrical wire routing directly within the power storage device structure, eliminating the need for separate exterior protective members. The wires are routed through the internal space of the power storage device, merging the wire protection function with the device housing itself. This integration reduces the vertical height dimension by removing additional protective layers and simplifies assembly by eliminating separate protection components.
3Power
If large-diameter electrical wires are routed between the floor panel and vehicle frame, then sufficient power transmission is achieved, but the vertical height dimension increases due to wire bundle volume
Solution Approach 1:
The patent nests the large-diameter electrical wires within the internal space of the power storage device, specifically utilizing the space between the power storage modules and the power storage cover. This nesting arrangement allows thick power transmission wires to be accommodated without increasing the external vertical height dimension of the mounting structure, as the wires are contained within the existing device envelope rather than extending externally.
