Movable Output End Protection Support for Battery Pack Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In battery packs, the inaccurate positioning between the output pole and the protection support results in dimensional deviations, leading to increased contact resistance, heat generation, and safety risks due to poor fitting.
Innovation Solution
The implementation of a battery pack design featuring a box body with two movably arranged output end protection supports, allowing for precise alignment and connection of the output poles, ensuring accurate fitting and reduced contact resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the output pole and protection support are rigidly fixed without movable arrangement, then the structural stability is improved, but the positioning accuracy deteriorates due to dimensional deviations
Solution Approach 1:
The protection support is designed with movable arrangement between the first and second output end protection supports, allowing them to move relative to each other. This dynamic structure enables automatic adjustment to accommodate dimensional variations while maintaining accurate positioning of the output pole connection, thereby resolving the contradiction between manufacturing precision and structural stability.
2Reliability
If the output pole and protection support are closely fitted, then the contact resistance is reduced, but the heat generation increases due to poor fitting in conventional designs
Solution Approach 1:
The movable arrangement of the first and second output end protection supports enables them to dynamically adjust their positions to achieve close fitting with the output pole. This ensures low contact resistance and reliable electrical connection, thereby reducing heat generation from poor fitting while maintaining connection reliability.
3Productivity
If the protection support uses fixed positioning, then the assembly process is simplified, but the assembly efficiency deteriorates due to need for precise manual positioning
Solution Approach 1:
The movable arrangement between the first and second output end protection supports allows them to automatically adjust during assembly, eliminating the need for precise manual positioning. This dynamic adjustment mechanism simplifies the assembly process while improving assembly efficiency, as the supports self-align to achieve accurate positioning without complex manual intervention.
