Battery Pack Guide Member Layout for Stronger Compact Wiring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guide members face a trade-off between reducing size and enhancing strength, as increasing the width of the partition wall for locking mechanisms compromises the guide member's size, while decreasing its width compromises strength.
Innovation Solution
The guide member features a partition wall with locking mechanisms displaced from each other in the predetermined direction, incorporating deflectable locking parts and bundled wiring, positioned between battery modules to enhance strength and reduce size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the width of the partition wall is increased to maintain strength around the locking mechanism, then the strength is improved, but the guide member size increases
Solution Approach 1:
The locking mechanisms are arranged in the width direction of the partition wall rather than being aligned in the longitudinal direction. This dimensional repositioning allows the locking mechanisms to be distributed across the width of the partition wall, eliminating the need to increase the longitudinal width of the partition wall while maintaining sufficient strength around each locking mechanism.
2Volume of moving object
If the width of the partition wall is decreased to reduce guide member size, then the size is reduced, but the strength around the locking mechanism decreases
Solution Approach 1:
By relocating the locking mechanisms to be arranged in the width direction of the partition wall, the partition wall can be made narrower in the longitudinal direction without compromising strength. The width direction arrangement distributes the locking mechanisms across the available width, maintaining structural integrity while reducing overall guide member size.
3Device complexity
If the locking mechanisms are aligned in the predetermined direction, then the guide member structure is simplified, but the partition wall width must be increased to maintain strength
Solution Approach 1:
The locking mechanisms are arranged in the width direction of the partition wall instead of being aligned in the longitudinal direction. This arrangement maintains relative simplicity in the guide member structure while avoiding the need to increase the longitudinal width of the partition wall, thus reducing overall guide member size.

AI summary
A first guide member (300A) includes a first partition wall (308A) separating a first right guide groove (310A) and a first left guide groove (320A) that extend in the X direction, a pair of first locking parts (312A) to lock a first low-voltage wiring member (510A) inserted into the first right guide groove (310A) with at least part of the pair provided at the first partition wall (308A), and a pair of second locking parts (322A) to lock a first lower high-voltage wiring member (520A) inserted into the first left guide groove (320A) with at least part of the pair provided at the first partition wall (308A). The pair of first locking parts (312A) of the first right guide groove (310A) and the pair of second locking parts (322A) of the first left guide groove (320A) are displaced from each other in the X direction.
