Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If calibration routines are performed to ensure accurate analyte sensor readings, then measurement precision is improved, but system complexity and potential for calibration failures increase
Solution Approach 1:
The system implements automated feedback mechanisms that monitor calibration parameters and sensor readings, automatically detecting calibration failures and triggering appropriate responses without requiring complex manual intervention systems
Solution Approach 2:
The calibration system performs self-diagnosis and self-correction through automated failure detection and notification mechanisms, reducing the need for complex external monitoring and manual calibration management
2Reliability
If calibration failure detection mechanisms are implemented, then reliability is improved, but device complexity increases
Solution Approach 1:
Automated feedback loops continuously monitor calibration parameters and sensor performance, enabling reliable failure detection through simple comparison of measured values against expected ranges without requiring complex diagnostic algorithms
Solution Approach 2:
The system uses intermediate notification mechanisms that translate complex calibration failure conditions into simple, actionable alerts, separating the complexity of failure detection from the user interface
3Productivity
If automated calibration monitoring is implemented, then productivity is improved, but use of energy increases
Solution Approach 1:
The calibration monitoring system operates periodically rather than continuously, checking calibration parameters at scheduled intervals to maintain productivity benefits while minimizing energy consumption during battery-powered operation
Solution Approach 2:
The system leverages existing sensor readings and calibration data already being collected for normal operation, performing failure detection as a byproduct of routine measurements without requiring additional energy-intensive dedicated monitoring hardware
