Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual refrigerant level measurement methods are used, then diagnostic capability is provided, but measurement accuracy deteriorates due to system variation and refrigerant collection issues
Solution Approach 1:
The patent replaces manual mechanical measurement methods with electronic sensors that automatically measure temperature, pressure, and humidity. This substitution eliminates the reliability issues of manual methods while providing continuous, accurate data for refrigerant level determination.
Solution Approach 2:
The patent introduces electronic sensors as intermediaries between the refrigerant system and the diagnostic process. These sensors indirectly measure refrigerant levels through temperature, pressure, and humidity readings, providing accurate measurements without direct observation challenges.
2Ease of operation
If external power sources and manual calibration are required, then sensor functionality is maintained, but system complexity and ease of operation deteriorate
Solution Approach 1:
The patent implements self-service through automatic calibration capabilities and integrated power management. The system calibrates itself without manual intervention and manages its own power requirements, eliminating the need for external power sources and manual calibration procedures.
Solution Approach 2:
The patent merges the power source, calibration system, and sensor functions into an integrated unit. This combination eliminates the need for separate external components, reducing system complexity while maintaining full functionality.
3Measurement precision
If multiple separate components are used for data collection, then measurement capability is provided, but data accuracy deteriorates due to calibration issues
Solution Approach 1:
The patent combines temperature, pressure, and humidity sensors into an integrated measurement system. This merging ensures consistent calibration across all sensors and eliminates the accuracy issues that arise from multiple separate calibrated components.
Solution Approach 2:
The patent creates a multi-functional sensor system that performs temperature, pressure, and humidity measurements simultaneously. This universal system provides accurate data across multiple parameters while reducing the complexity of managing separate calibrated devices.
4Ease of operation
If simple viewing windows are used for refrigerant observation, then diagnostic capability is provided, but measurement reliability deteriorates due to system operation variations
Solution Approach 1:
The patent replaces simple visual viewing windows with electronic sensing systems. This substitution provides accurate, objective measurements of refrigerant levels through temperature, pressure, and humidity data, eliminating the subjectivity and inaccuracy of visual observation.
Solution Approach 2:
The patent implements feedback through continuous electronic monitoring of system parameters. This feedback mechanism provides real-time, accurate information about refrigerant levels, replacing the static and unreliable visual indication from viewing windows.
