Battery Pack Bracket Layout for High-Mounted Disconnect Switch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery packs face challenges in efficiently mounting components around the disconnect switch due to limited space, particularly when the switch is locally arranged, and in arranging the switch at a higher position without compromising mounting efficiency.
Innovation Solution
A battery pack design featuring multiple overlapping brackets with a disconnect switch and a breather positioned on opposite sides, allowing the switch to be locally arranged at a high position while improving mounting efficiency through the use of larger areas for other components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the support member is locally arranged in a region where the service plug is arranged, then the service plug can be mounted, but the area of the support member is relatively small making it difficult to mount other components
Solution Approach 1:
The patent transitions from a two-dimensional planar support member to a three-dimensional bracket structure that extends vertically. The bracket has a first bracket portion and a second bracket portion arranged at different heights, creating a multi-level mounting surface that increases the effective area for component placement without expanding the horizontal footprint.
2Ease of operation
If the SD/SW and another electronic component are mounted on the middle base, then both components can be accommodated, but it is difficult to arrange the SD/SW at a higher position than the another electronic component
Solution Approach 1:
The support structure is segmented into multiple functional portions: a first bracket portion for mounting the disconnect switch and a second bracket portion for mounting other electronic components. This segmentation allows independent positioning of each component at optimal heights, with the disconnect switch placed higher for accessibility and other components placed lower for efficient use of space.
3Ease of operation
If the disconnect switch is arranged at a higher position for accessibility, then ease of operation is improved, but the area available for mounting other components is reduced
Solution Approach 1:
The patent utilizes the vertical dimension to resolve the space conflict. By arranging the disconnect switch higher on the first bracket portion and placing other components on the second bracket portion at a lower level, the design achieves both high accessibility for the disconnect switch and adequate mounting area for other components through three-dimensional spatial organization.
