Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If simple voltage measurement is used to test battery condition, then the testing process is simple and quick, but the accuracy of determining battery condition is insufficient
Solution Approach 1:
The patent combines multiple testing methods (dynamic parameter measurement and load resistance response measurement) into a single integrated testing system. The electronic battery tester simultaneously performs both types of measurements and correlates the results to achieve accurate battery condition assessment while maintaining operational simplicity.
Solution Approach 2:
The electronic battery tester is designed to perform multiple functions: measuring dynamic parameters, measuring load resistance responses, and providing an integrated assessment of battery condition. This multi-functional approach enables accurate testing without requiring separate specialized devices for each measurement type.
2Measurement precision
If dynamic parameter measurement is used to improve battery testing accuracy, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The patent integrates dynamic parameter measurement capabilities directly into the electronic battery tester, combining multiple measurement functions into a single unified device. This integration reduces the need for separate specialized equipment and simplifies the overall testing system while maintaining high measurement precision.
3Measurement precision
If load test with known load is used to discharge the battery, then the battery condition can be assessed, but the testing time and energy consumption increase
Solution Approach 1:
The patent applies a controlled load to the battery for a limited duration to obtain sufficient data for condition assessment without requiring complete battery discharge. This partial action approach provides accurate battery condition information while minimizing testing time and energy consumption compared to full discharge tests.
