Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a monitoring device operates for an extended period, then productivity is improved, but measurement precision deteriorates due to calibration drift
Solution Approach 1:
The system performs preliminary calibration by storing calibration data in the probe's memory before the probe is installed. This pre-calibration data is then used by the monitoring device to maintain measurement precision throughout the extended monitoring period without requiring recalibration during operation.
Solution Approach 2:
The calibration information is copied from an external calibration source into the probe's memory during the calibration phase. This copied calibration data is then used by the monitoring device to maintain accurate measurements over extended periods without needing to access the original calibration source or perform recalibration.
2Measurement precision
If a monitoring device is removed for recalibration, then measurement precision is maintained, but loss of time occurs due to monitoring gaps
Solution Approach 1:
The calibration information is extracted and stored in the probe's memory during an initial calibration phase. This allows the probe to operate independently for extended periods without needing to be removed from the monitoring position for recalibration, thus eliminating monitoring gaps while maintaining measurement precision.
Solution Approach 2:
The calibration is performed in advance and the calibration data is stored in the probe's memory before the probe is installed for extended monitoring. This preliminary calibration action enables the probe to maintain measurement precision throughout the extended monitoring period without requiring removal for recalibration.
3Reliability
If calibration information is stored in the probe memory, then reliability is improved, but device complexity increases
Solution Approach 1:
The calibration information is copied into the probe's memory during an initial calibration phase. This approach improves reliability by ensuring calibration data is available throughout the probe's operational life without requiring complex recalibration mechanisms, while the copying process itself is simple and does not significantly increase probe complexity.
Solution Approach 2:
The probe with stored calibration information in its memory serves itself by using the pre-stored calibration data to maintain measurement accuracy throughout its operational life. This self-service capability improves reliability without requiring complex external calibration systems or frequent interventions, thus not significantly increasing overall system complexity.
