Solution Overview
Problem
Current lubricant dilution detection methods in lubrication systems are inadequate, often requiring manual testing and may fail to accurately detect dilution, leading to potential damage to moving components due to reduced viscosity.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual testing methods are used to detect lubricant dilution, then the system complexity is reduced, but the measurement precision and reliability of dilution detection deteriorates
Solution Approach 1:
The patent replaces manual mechanical testing methods with an automated electronic detection system that uses pressure sensors and controllers to automatically monitor lubricant pressure and detect dilution, thereby improving measurement precision while maintaining acceptable system complexity
Solution Approach 2:
The system enables self-service detection by automatically monitoring lubricant pressure and identifying dilution conditions without requiring manual intervention, achieving both high measurement precision and operational simplicity
2Measurement precision
If lubricant pressure is measured during shutdown events only, then the measurement precision for detecting dilution is improved, but the duration of monitoring is reduced
Solution Approach 1:
The system performs preliminary detection by measuring lubricant pressure during shutdown events before the engine is fully stopped, allowing detection of dilution while the pump is still operating and pressure is maintained, thereby improving detection accuracy without requiring continuous long-term monitoring
3Ease of operation
If a pressure threshold is used to determine lubricant dilution, then the ease of operation is improved, but the measurement precision may be reduced due to threshold setting challenges
Solution Approach 1:
The system uses feedback mechanisms where the controller continuously compares measured pressure values against predetermined thresholds and provides output signals when dilution is detected, allowing for easy operation while maintaining precision through automated threshold comparison and adaptive monitoring
