Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a voltage sensor is used to convert analog voltage to digital value using a predefined correlation, then the digital voltage output can be obtained for control purposes, but measurement errors occur affecting electric power control precision
Solution Approach 1:
The patent performs preliminary calibration of the voltage sensor during the charging process. The control unit calibrates the voltage sensor by comparing the sensor output with the known charging voltage from the power source, and stores the calibration data for future use. This preliminary action eliminates measurement errors before they affect the electric power control during vaporization operations.
Solution Approach 2:
The patent implements a feedback mechanism where the control unit continuously monitors the voltage sensor output during charging and operation. The system uses the calibration feedback from charging processes to adjust and correct the voltage measurements, ensuring accurate electric power control. The feedback loop maintains measurement precision by compensating for drift and errors in real-time.
2Measurement precision
If calibration is performed during charging of the electric power source, then the voltage sensor accuracy is improved, but the charging process time is extended
Solution Approach 1:
The patent implements periodic calibration during the charging process rather than continuous calibration. The control unit performs voltage sensor calibration at specific intervals or at key points during charging (such as when the battery reaches certain charge levels). This periodic approach maintains measurement precision while minimizing the impact on overall charging time, as calibration is performed only when necessary rather than continuously.
3Manufacturing precision
If the voltage sensor is calibrated based on charging dynamics, then the precision of electric power control is enhanced, but the control system complexity increases
Solution Approach 1:
The patent implements a self-service calibration system where the control unit automatically performs voltage sensor calibration using the known charging voltage from the power source. The system calibrates itself without requiring external calibration equipment or manual intervention. The control unit stores calibration data in memory and automatically applies corrections during operation, enhancing precision while keeping the system relatively simple by eliminating the need for complex external calibration apparatus.
