Engineering Contradiction Analysis
1Ease of manufacture
If a single common calibration reference is used for multiple spectrometer systems, then calibration cost is reduced, but measurement precision deteriorates due to system-to-system variations
Solution Approach 1:
The calibration reference is segmented into multiple individual references, each uniquely identified and tailored to specific spectrometer systems or components. This allows each spectrometer to use its own customized calibration reference, maintaining measurement precision while enabling independent calibration of each system rather than requiring a single universal reference.
Solution Approach 2:
Each calibration reference is customized with local quality characteristics specific to its associated spectrometer system or component. The calibration data stored in the database contains system-specific parameters and corrections that are locally optimized for each spectrometer, ensuring accurate spectral measurements while accommodating manufacturing variations among individual systems.
2Measurement precision
If highly matching calibration references are manufactured for each spectrometer system, then measurement precision is improved, but manufacturing cost increases
Solution Approach 1:
Instead of manufacturing physically identical calibration references for each spectrometer, the system creates digital copies of calibration data stored in a database. Each calibration reference can be replicated as digital information and associated with unique identifiers, providing customized calibration without the cost of manufacturing multiple physical references with high precision matching.
Solution Approach 2:
The calibration references utilize parameter changes in the digital domain rather than physical manufacturing variations. By storing calibration data with system-specific parameters in a database and retrieving them based on unique identifiers, the system achieves customized calibration for each spectrometer through data parameter adjustment rather than expensive physical manufacturing processes.
3Measurement precision
If spectrometer systems with unique identifiers and individual calibration data are implemented, then spectral data consistency across systems is improved, but device complexity increases
Solution Approach 1:
The calibration system achieves universality through a centralized database that can serve multiple spectrometer systems. The same database infrastructure and calibration data format can be used across different spectrometers, while unique identifiers enable system-specific calibration retrieval. This multi-functional approach maintains spectral data consistency without requiring separate calibration systems for each spectrometer.
Solution Approach 2:
A database acts as an intermediary between spectrometer systems and calibration references. The database receives calibration data, stores it with unique identifiers, and retrieves appropriate calibration references based on system identification. This intermediary layer manages the complexity of individualized calibration while presenting a simplified interface to users and maintaining spectral data consistency across multiple systems.
