Engineering Contradiction Analysis
1Quantity of substance
If multiple different measuring devices are used to measure battery resistance, then measurement coverage and data quantity are improved, but measurement precision deteriorates due to device-specific deviations
Solution Approach 1:
The system measures the same battery sample with multiple devices, compares the results, and uses the measured deviations as feedback to automatically calibrate each device's measurements. This closed-loop feedback mechanism ensures that while multiple devices are used for data quantity, the precision is maintained through continuous calibration based on actual measurement discrepancies.
Solution Approach 2:
The invention changes the measurement parameters by introducing deviation values and calibration factors for each measuring device. By measuring resistance multiple times with different devices and calculating the statistical deviations, the system transforms raw measurements into calibrated values that compensate for device-specific characteristics, thus maintaining precision across multiple devices.
2Measurement precision
If calibration data is collected and stored for each measuring device, then measurement precision is improved through calibration, but device complexity increases due to additional calibration procedures
Solution Approach 1:
The system performs self-calibration by automatically measuring the same battery sample with multiple devices, calculating the deviations, and storing calibration data without requiring external intervention or complex manual calibration procedures. This self-service approach simplifies the overall process while achieving precise calibration.
Solution Approach 2:
The invention performs preliminary calibration measurements by collecting resistance data from multiple devices on the same battery sample before actual use. These preliminary actions establish the baseline deviation values that are stored and applied for subsequent measurements, reducing the need for repeated complex calibration procedures.
