Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a secondary power device is used to prevent data loss during sudden power-offs, then reliability is improved, but device complexity increases due to the need for monitoring and calibration systems
Solution Approach 1:
The system performs preliminary calibration of reference parameters (first reference parameter during first calibration interval, second reference parameter during second calibration interval) before actual monitoring begins. This preliminary action ensures that the monitoring system is properly configured with accurate baseline values, reducing the need for complex real-time adjustments and improving overall system reliability without adding operational complexity.
Solution Approach 2:
The monitoring system continuously compares the voltage of the secondary power device against the calibrated reference parameters and reference levels. When deviations are detected, the system generates feedback signals to indicate abnormal states. This feedback mechanism enables automatic detection and reporting of issues without requiring complex manual monitoring procedures, thus improving reliability while keeping the system manageable.
2Measurement precision
If reference parameters are calibrated using voltage measurements, then measurement precision is improved, but device complexity increases due to multiple calibration intervals and reference levels
Solution Approach 1:
The calibration process is divided into distinct segments: a first calibration interval for setting the first reference parameter, and a second calibration interval for setting the second reference parameter. Each interval focuses on specific calibration tasks, allowing for precise voltage measurements to be established systematically. This segmentation reduces the complexity of simultaneous multi-parameter calibration while maintaining high measurement precision.
Solution Approach 2:
The system changes calibration parameters over time by using different reference parameters for different calibration intervals. The first reference parameter is established during the first calibration interval, and the second reference parameter is established during the second calibration interval. This temporal separation of parameter changes allows for accurate voltage measurements without requiring all parameters to be calibrated simultaneously, reducing the overall complexity of the calibration process.
3Reliability
If continuous monitoring is performed to detect abnormal states in real-time, then reliability is improved, but use of energy increases due to ongoing calibration and monitoring operations
Solution Approach 1:
The system performs calibration and monitoring operations periodically rather than continuously. The first calibration interval and second calibration interval are separated by time, and monitoring occurs at scheduled intervals. This periodic action reduces energy consumption compared to continuous operation while still providing real-time detection capability when needed, as the system can quickly detect abnormal states during monitoring windows and alert users between monitoring cycles.
