Movable Cover Conductive Connection Assembly for Compact Battery Packs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conductive connection assemblies for battery packs are inefficient in space usage during maintenance, as they do not adequately prevent worker safety hazards from live electrical components.
Innovation Solution
A conductive connection assembly featuring a cover that transitions between two positions, with a tool access hole facing or not facing the fastening member, ensuring safety during maintenance and reducing space by positioning closer to the conductive connection member after use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cover is provided with an insertion hole to allow tool access for fastening the fastening member, then ease of operation during maintenance is improved, but the space required for the battery pack increases due to the need for safety distance from live parts
Solution Approach 1:
The cover is designed to be movable between a first position during maintenance (where the insertion hole allows tool access to the fastening member) and a second position during normal operation (where the cover moves closer to the conductive connection member). This dynamic positioning enables the same component to satisfy both safety requirements during operation and accessibility requirements during maintenance, resolving the contradiction between ease of operation and space consumption.
2Reliability
If the cover is spaced apart from the fastening member to prevent accidental contact with live parts, then worker safety is improved, but the space usage efficiency deteriorates
Solution Approach 1:
The cover transitions between two positions: during maintenance, it maintains a safety distance from the fastening member to prevent accidental contact with live parts; during normal operation, it moves closer to the conductive connection member to optimize space usage. This dynamic adjustment allows the system to satisfy both safety requirements and space efficiency requirements at different operational stages.
3Volume of moving object
If the cover transitions between first and second positions, then space saving is achieved, but the device complexity increases
Solution Approach 1:
The cover is designed with movable characteristics, transitioning between a first position (during maintenance) and a second position (during normal operation). This dynamic positioning enables the same component to satisfy both safety requirements during operation and accessibility requirements during maintenance, resolving the contradiction between ease of operation and space consumption.
4Volume of moving object
If the cover is positioned closer to the conductive connection member in the second position, then space saving is achieved, but the ease of operation during maintenance deteriorates if the insertion hole does not face the fastening member
Solution Approach 1:
The cover transitions between a first position where the insertion hole faces the fastening member (enabling tool access during maintenance) and a second position where the cover moves closer to the conductive connection member (optimizing space usage). This dynamic repositioning allows the system to achieve both space efficiency and operational accessibility at different times.
