Sealed Battery Test Chamber With Tilting Opening Tools
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing secondary battery testing apparatuses lack the capability to perform tests on batteries of various sizes and types, as they are limited to forming openings only at specific positions on the outer housing, which restricts their general-purpose application and can lead to electrical short-circuiting or inefficient gas release.
Innovation Solution
A secondary battery testing apparatus with a sealed container, a fixing device, a first tool with a tilting mechanism for forming openings at desired positions, and a release outlet for gas, along with a gas measurement system and trap apparatus to prevent contamination, allowing for comprehensive testing of various battery sizes and forms while maintaining airtightness and preventing short-circuiting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-position opening tool is used, then the device structure is simple, but the adaptability to different battery sizes and types is poor
Solution Approach 1:
The opening tool is designed with dynamic positioning capability, allowing it to move along the battery surface and tilt at various angles. The tool can be positioned at different locations based on battery size and type, transforming a static fixed-position tool into a dynamic adaptable tool without significantly increasing overall device complexity
Solution Approach 2:
The opening tool is designed as a universal tool that can accommodate different battery types and sizes through adjustable positioning mechanisms. A single tool design serves multiple functions across different battery configurations, eliminating the need for multiple specialized tools for different battery types
2Manufacturing precision
If openings are formed only at specific positions, then the device complexity is low, but the manufacturing precision of opening location is insufficient
Solution Approach 1:
The positioning mechanism provides different positioning characteristics for different regions of the battery. The system allows precise positioning at critical locations (such as avoiding electrode areas) while maintaining flexibility for other regions, applying localized precision where needed rather than uniform precision across all positions
3Measurement precision
If the sealed container maintains strict airtightness, then gas measurement accuracy is improved, but the ease of operation for tool manipulation is reduced
Solution Approach 1:
A sealed transfer mechanism acts as an intermediary between the external environment and the sealed container interior. This intermediary allows the opening tool to be manipulated from outside the sealed container while maintaining the airtight seal, enabling both precise gas measurement and easy tool operation through the intermediary interface

AI summary
A secondary battery is fixed in a sealed container. A first tool unit and a second tool unit are provided on the sealed container. The first tool unit is formed from a first tool and a first holder. The second tool unit is formed from a second tool and a second holder. The first holder holds the first tool while maintaining airtightness of the sealed container, while allowing an advancing/retreating movement and a tilting movement of the first tool. The second holder has a structure similar to that of the first holder.
