Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual judgement is used to test float liquid level transmitter, then the testing process is simple and fast, but the reliability of testing is poor due to potential erroneous qualification judgments
Solution Approach 1:
The patent replaces the manual mechanical judgement process with an automated computational system. The computation unit automatically compares measured values with standard values, calculates error ranges, and generates qualification determinations, eliminating human subjectivity and error in the testing process.
Solution Approach 2:
The patent introduces a testing device as an intermediary between the float liquid level transmitter and the final qualification judgment. This intermediary object (testing device) objectively mediates the comparison between measured and standard values, providing a reliable basis for qualification determination without direct human intervention.
2Measurement precision
If automated computation and analysis are implemented, then testing reliability is improved, but the device complexity increases
Solution Approach 1:
The testing device integrates multiple functions into a single universal system: data acquisition from the transmitter, computation of standard values, comparison analysis, error calculation, and qualification determination. This multi-functional integration improves measurement precision while managing overall system complexity through consolidation.
Solution Approach 2:
The computation unit performs self-service by automatically computing standard values from input parameters and autonomously comparing measured values against these standards. The system serves itself by generating calibration curves and qualification determinations without requiring external manual analysis, thereby improving measurement precision.

AI summary
A testing system for float liquid level transmitter includes a computation unit, an operation interface, a storage unit and a display unit. The computation unit computes basic data associated with the float liquid level transmitter to obtain corresponding standard values and the display unit displays the standard values. After a float liquid level transmitter performs measurement, the computation unit fetches displayed values measured by the float liquid level transmitter and obtain an error range by comparing the displayed values with the standard values; the computation unit analyzes the error range to provide analyzed data and determines whether the float liquid level transmitter is qualified based on the error range.
