Engineering Contradiction Analysis
1Measurement precision
If complex calibration procedures using additional external systems and equipment are used, then calibration accuracy may be improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent combines the calibration function with the sensor device itself by integrating a temperature sensor and using spectroscopic information from the analyte. This eliminates the need for separate external calibration systems and equipment, allowing calibration to be performed using only the implanted sensor device and its integrated components.
Solution Approach 2:
The sensor device performs self-calibration by using its own temperature sensor and spectroscopic measurements of the analyte. The device automatically derives temperature information from spectroscopic data and uses this for calibration without requiring external systems, making the calibration process self-contained and eliminating manual intervention.
2Measurement precision
If complex calibration procedures with additional external systems are used, then calibration may be performed, but ease of operation deteriorates due to manual errors and hassle
Solution Approach 1:

The device automatically derives temperature information from spectroscopic data and uses this for calibration without requiring external systems, making the calibration process self-contained and eliminating manual intervention.
Solution Approach 2:
The system uses feedback from the temperature sensor and spectroscopic measurements to automatically adjust and calibrate the sensor. The derived temperature information from spectroscopic data is fed back into the calibration process, enabling automatic correction and eliminating manual calibration steps that are prone to human error.
