Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual calibration is used to set the set-off value, then the system can operate with simple hardware, but measurement precision deteriorates due to variability and potential false positives
Solution Approach 1:
The system automatically determines the set-off value by measuring the baseline conductivity of the fluid without user intervention. The microprocessor calculates the set-off value based on initial measurements, eliminating the need for manual calibration while improving measurement precision and reducing false positives.
Solution Approach 2:
The system performs preliminary measurements of the fluid's baseline conductivity before actual measurements begin. These preliminary actions establish the reference set-off value that will be used for subsequent conductivity measurements, ensuring accuracy without requiring manual setup.
2Adaptability or versatility
If a fixed set-off value is used, then the system operation is simple, but adaptability deteriorates when fluid properties vary
Solution Approach 1:
The set-off value transitions from a fixed parameter to a dynamic one that automatically adjusts based on the measured fluid properties. The system continuously adapts the set-off value according to the baseline conductivity measurements, allowing the system to handle variations in fluid composition without requiring manual reconfiguration.
Solution Approach 2:
The system uses feedback from baseline measurements to automatically adjust the set-off value. By continuously monitoring the fluid's conductivity characteristics and adjusting the reference value accordingly, the system maintains adaptability to different fluid conditions while preserving ease of operation through automation.
3Measurement precision
If sensitivity correction factor is applied, then measurement precision improves, but device complexity increases due to additional control mechanisms
Solution Approach 1:
The system adjusts the sensitivity correction factor by modifying the set-off value parameter based on measured baseline conductivity. This parameter change allows the system to compensate for variations in fluid properties and improve measurement precision without requiring complex hardware modifications, as the adjustment is achieved through software-based parameter optimization.

AI summary
This disclosure relates to an autosensitive detector and an autosensitive measurement system with a self-adjustable set-off value, and more specifically, to a probe for adaptation to an environmental parameter such as liquids adapted to reset its measured sensitivity each time the probe is enabled or turned on, which can be further desensitized by adjusting a sensitivity correction factor by a factor (F) within the range of 0.05<F<2.01 of the reset sensitivity or of up to ten times or ten percent of the reset sensitivity but most likely of 10 to 20% from the initial value using a remote control system such as a handheld programmer or programming function of the sensor board.
