Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If proven or recalibration is performed to correct measurement characteristics, then measurement precision is improved, but device complexity and operator skill requirements increase
Solution Approach 1:
The flow meter system performs self-diagnosis and self-calibration by automatically detecting measurement characteristic changes and executing recalibration procedures without requiring external intervention or complex operator actions. The system serves itself by monitoring its own performance and initiating corrective measures.
Solution Approach 2:
The system continuously monitors measurement characteristics and provides feedback to detect deviations caused by corrosion, erosion, or coating deposition. This feedback loop triggers automatic recalibration when measurement accuracy deteriorates, creating a closed-loop control system that maintains precision without manual intervention.
2Measurement precision
If proven or recalibration is performed to correct measurement characteristics, then measurement precision is improved, but loss of time occurs due to complex procedures
Solution Approach 1:
The system performs preliminary monitoring of measurement characteristics continuously during normal operation, detecting changes before they significantly impact accuracy. This early detection allows for timely recalibration at optimal moments, preventing excessive time loss and maintaining precision proactively rather than reactively.
Solution Approach 2:
The automated self-calibration system executes recalibration procedures without requiring operator intervention, eliminating the time operators would spend on manual calibration tasks. The system performs all necessary measurements and adjustments autonomously, significantly reducing the time required for maintaining measurement precision.
3Measurement precision
If manual verification by experienced operators is used, then measurement precision is maintained, but ease of operation deteriorates due to skill requirements
Solution Approach 1:
The flow meter system performs self-diagnosis and self-calibration by automatically detecting measurement characteristic changes and executing recalibration procedures without requiring external intervention or complex operator actions. The system serves itself by monitoring its own performance and initiating corrective measures.
Solution Approach 2:
The system introduces an automated control system as an intermediary between the measurement process and the operator. This intermediary handles all complex calibration and verification tasks automatically, eliminating the need for operators to possess specialized skills while maintaining measurement precision through automated monitoring and adjustment.
