Engineering Contradiction Analysis
1Measurement precision
If individual calibration of sensor and measuring device is performed, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The calibration process is segmented into two independent phases: sensor calibration (performed once during manufacturing) and system calibration (performed when sensor is paired with measuring device). This segmentation allows the sensor to be pre-calibrated independently without requiring cumulative calibration with the measuring device, thereby reducing overall system complexity while maintaining precision.
Solution Approach 2:
The sensor is calibrated in advance during manufacturing before being paired with the measuring device. The calibration data is stored in the sensor's memory, enabling the sensor to provide corrected measurement values directly to the measuring device without requiring on-site cumulative calibration. This preliminary action eliminates the need for complex cumulative calibration procedures.
2Measurement precision
If cumulative calibration is performed, then measurement precision is improved, but adaptability decreases
Solution Approach 1:
The calibration process is divided into sensor-level calibration (independent and reusable) and system-level calibration (context-specific). This segmentation enables the same calibrated sensor to be used across different measuring devices and applications without requiring re-calibration, significantly improving adaptability while maintaining precision through the stored calibration data.
Solution Approach 2:
Instead of performing cumulative calibration for each specific sensor-device pairing, the sensor's calibration characteristics are copied and stored in its memory. This calibration copy can then be reused across different measuring devices and applications, eliminating the need for repetitive cumulative calibration and enhancing industrial flexibility.
3Measurement precision
If high individual accuracy is required for sensor and measuring device, then measurement precision is improved, but manufacturing cost increases
Solution Approach 1:
The sensor is calibrated in advance during manufacturing and the calibration data is stored in its memory. This preliminary calibration eliminates the need for expensive cumulative calibration procedures at the time of system assembly, reducing manufacturing costs while maintaining high measurement precision through the pre-stored calibration characteristics.
Solution Approach 2:
The sensor performs self-calibration during manufacturing and stores the calibration data in its own memory. This self-service approach eliminates the need for complex cumulative calibration procedures requiring coordination between sensor and measuring device manufacturers, thereby reducing overall manufacturing costs while preserving measurement accuracy.
