Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a vacuum environment is used for evaluation, then detection accuracy of venting gas is improved, but device complexity and testing cost increase
Solution Approach 1:
The patent extracts the sensing function from a complex vacuum environment and implements it within a simple chamber structure. The sensing member is placed inside the chamber to directly detect venting gas, eliminating the need for external vacuum equipment while maintaining detection accuracy.
Solution Approach 2:
The chamber structure serves multiple functions simultaneously: it provides the enclosed space for the battery assembly, contains the sensing member for detection, and maintains the necessary environment for accurate measurement without requiring external vacuum systems. The system is self-sufficient for detection purposes.
2Measurement precision
If a vacuum environment is used for evaluation, then detection accuracy of venting gas is improved, but testing time and productivity decrease
Solution Approach 1:
The patent removes the time-consuming vacuum environment setup and replaces it with a simple chamber structure that allows immediate testing. The sensing member directly detects venting gas within the chamber without requiring prolonged vacuum establishment, significantly reducing testing time.
Solution Approach 2:
The invention skips the lengthy vacuum environment preparation step and proceeds directly to the detection phase. The chamber structure enables immediate placement of the battery assembly and instant monitoring of venting gas, rushing through the testing process while maintaining accuracy.
3Measurement precision
If a vacuum environment is used for evaluation, then venting gas detection is possible, but ease of operation deteriorates
Solution Approach 1:
The patent extracts the detection capability from a complex vacuum environment and relocates it to a simple chamber structure. The sensing member is positioned within the chamber to detect venting gas directly, eliminating the need for operators to manage vacuum systems while preserving detection functionality.
Solution Approach 2:
The chamber structure automatically provides the necessary enclosed environment for detection without requiring manual vacuum adjustment. The system self-regulates the testing conditions, making operation straightforward while maintaining venting gas detection capability.
4Device complexity
If a simple chamber structure is used, then device complexity is reduced, but airtightness and sealing performance may worsen
Solution Approach 1:
The patent employs a sealing member made of flexible material that conforms to the chamber structure to ensure airtightness. The flexible sealing member effectively blocks gas leakage at the interface between the battery assembly and chamber, maintaining reliability despite the simple overall structure.
Solution Approach 2:
The chamber structure combines different materials with complementary properties: a rigid or semi-rigid body member for structural integrity and a flexible sealing member for airtightness. This composite approach achieves both simplicity and reliability without compromising performance.
