Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional measurement methods are used to measure battery module strain, then measurement accuracy may be sufficient, but the measurement process becomes complex and difficult to implement
Solution Approach 1:
The patent replaces traditional mechanical strain measurement systems with an electrical measurement system. Electrical sensors and circuits are used to detect and measure strain, converting mechanical deformation into electrical signals that are easier to process and analyze, thereby reducing system complexity while maintaining measurement accuracy
Solution Approach 2:
The patent introduces electrical sensors as intermediary elements between the battery module and the measurement system. These sensors act as mediators that convert physical strain into electrical signals, simplifying the overall measurement process and reducing the complexity of direct mechanical measurement systems
2Measurement precision
If comprehensive numerical information is collected from the battery module, then strain estimation accuracy improves, but the amount of data processing and system complexity increases
Solution Approach 1:
The patent segments the strain estimation process into distinct functional modules: data acquisition from multiple sensors, data processing and filtering, strain calculation algorithms, and result output. This modular approach allows comprehensive numerical information to be processed systematically, improving accuracy while managing complexity through organized data flow
Solution Approach 2:
The patent creates a multi-functional measurement system that simultaneously collects various numerical information (temperature, pressure, electrical parameters) and processes them to estimate strain. This universal system handles multiple types of data through integrated processing routines, reducing overall system complexity compared to separate specialized systems
