Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If current monitoring techniques are used, then the monitoring system is simple, but the detection precision and reliability are insufficient
Solution Approach 1:
The monitoring system is divided into three independent functional modules: a sensor unit for acquiring oil quality parameters, an analysis unit for processing and comparing data against thresholds, and a detection unit for identifying malfunctions. This segmentation allows each module to be optimized for its specific function, improving overall detection precision while maintaining manageable system complexity through modular design.
Solution Approach 2:
The monitoring system is designed to detect multiple types of engine malfunctions (fuel injection problems, lubrication issues, overheating, wear) through a single multi-functional platform that analyzes various oil quality parameters including viscosity, contaminants, and chemical composition. This universal approach improves detection precision across different failure modes without requiring separate specialized systems for each malfunction type.
2Reliability
If monitoring is performed continuously, then the reliability of engine operation is improved, but the energy consumption increases
Solution Approach 1:
The system uses the engine's existing lubricating oil circuit to provide monitoring functionality. The sensor unit taps into the oil flow already circulating through the engine, and the oil serves as both the lubricant and the medium carrying diagnostic information about engine health. This self-service approach enables continuous monitoring without requiring separate power-intensive sensing systems or additional fluid circulation.
Solution Approach 2:
The analysis unit monitors changes in oil quality parameters over time and compares them against threshold values to detect malfunctions. By tracking parameter evolution rather than requiring constant high-power active sensing, the system maintains high operational reliability through continuous passive monitoring while minimizing energy consumption. The system can adjust monitoring intensity based on detected parameter trends.
