Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If actively measured sensor data is used to evaluate a battery charge meter, then accurate results on actual IC hardware are obtained, but testing time and costs increase significantly
Solution Approach 1:
The patent applies preliminary action by pre-generating battery measurement data (voltage, current, temperature values) before actual testing. These pre-generated datasets simulate real battery behavior under various conditions, allowing the charge state controller to be evaluated without performing time-consuming active measurements during the testing phase. This resolves the contradiction by providing accurate evaluation results through pre-computed data while significantly reducing testing time.
2Reliability
If actively measured sensor data is used to evaluate a battery charge meter, then comprehensive testing is performed, but proprietary algorithms may be exposed to competitors
Solution Approach 1:
The patent applies copying by creating synthetic copies of battery measurement data that replicate the characteristics of real sensor readings without using actual proprietary algorithms. The pre-generated datasets include voltage, current, and temperature values that mimic real battery behavior, allowing comprehensive testing of the charge state controller while keeping the proprietary charge state algorithms confidential. This resolves the contradiction by providing testing completeness through data copies while maintaining algorithm security.
3Productivity
If pregenerated data is used to simulate charge states, then testing time and costs are reduced, but the complexity of data generation and management increases
Solution Approach 1:
The patent applies universality by designing a multi-functional system where the charge state controller can operate in both normal mode (using real sensor data) and testing mode (using pre-generated data). The communication interface and processing logic are universal, handling both real and simulated data seamlessly. This resolves the contradiction by improving testing efficiency through pre-generated data while managing complexity through a unified, multi-functional architecture that doesn't require separate systems for different operating modes.
