Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a complex configuration with additional components is used for reference measurements, then measurement precision can be improved, but device complexity increases
Solution Approach 1:
The patent merges the reference measurement function into the existing sample measurement optical system by placing the reference material at the observation window or in the tube covering it. This eliminates the need for separate reference measurement optical systems and additional components, thereby reducing device complexity while maintaining measurement precision through the use of the reference material for calibration.
2Measurement precision
If a large separation between sample and reference measurement optical systems is used, then measurement precision can be improved, but device complexity and size increase
Solution Approach 1:
The patent combines the sample and reference measurement paths into a single optical system. The reference material is positioned at the observation window or in the tube covering it, allowing the same optical path used for sample measurement to also serve for reference measurement. This eliminates the need for large separation between optical systems while maintaining measurement precision.
Solution Approach 2:
The observation window and tube structure serve multiple functions: they act as both the sample measurement interface and the reference material mounting position. This multi-functionality allows the system to perform both sample and reference measurements without requiring separate dedicated spaces, thereby reducing overall device complexity and size.
3Measurement precision
If additional components are added for reference measurements, then measurement precision can be improved, but ease of operation deteriorates
Solution Approach 1:
By integrating the reference material into the existing tube structure or observation window, the patent eliminates the need for separate calibration procedures and additional components. The system can switch between sample and reference measurement modes through the existing optical path, simplifying operation while maintaining calibration accuracy.
Solution Approach 2:
The reference material is positioned within the existing optical system structure, allowing the system to automatically perform reference measurements without requiring manual intervention to replace components or adjust separate calibration systems. This self-service approach simplifies operation while ensuring accurate calibration.
