Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If complex mathematical formulas are used to calculate blood parameters, then measurement coverage is expanded, but measurement accuracy deteriorates due to inability to account for conduit variations
Solution Approach 1:
The device performs self-calibration by automatically detecting conduit characteristics and adjusting measurement parameters accordingly. The control unit autonomously adapts to different conduits without requiring manual user calibration, thereby maintaining high accuracy across varying conduit types while expanding measurement coverage.
Solution Approach 2:
The system dynamically changes measurement parameters based on detected conduit properties. By monitoring conduit characteristics and adjusting optical or electrical parameters in real-time, the device maintains measurement accuracy across different conduit formulations, hardness levels, and colors.
2Measurement precision
If user calibration is required before measurement, then measurement accuracy can be maintained, but measurement speed and ease of operation deteriorate
Solution Approach 1:
The device performs self-calibration by automatically detecting conduit characteristics and adjusting measurement parameters accordingly. The control unit autonomously adapts to different conduits without requiring manual user calibration, thereby maintaining high accuracy across varying conduit types while expanding measurement coverage.
Solution Approach 2:
The device performs preliminary calibration automatically upon insertion into a conduit, before actual measurements are taken. This preliminary self-adjustment ensures that the system is already optimized for the specific conduit being used, eliminating the need for manual calibration steps and improving measurement speed.
3Measurement precision
If manual calibration by end user is performed, then measurement accuracy is maintained, but device complexity and operation complexity increase
Solution Approach 1:
The device performs self-calibration by automatically detecting conduit characteristics and adjusting measurement parameters accordingly. The control unit autonomously adapts to different conduits without requiring manual user calibration, thereby maintaining high accuracy across varying conduit types while expanding measurement coverage.
Solution Approach 2:
The system continuously monitors conduit characteristics and provides feedback to adjust measurement parameters automatically. This closed-loop control ensures accurate measurements while simplifying operation, as the device self-adjusts without requiring user intervention or complex manual calibration procedures.
