Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If pericritical fluids are used in engine systems, then engine efficiency and performance are improved, but monitoring and controlling phase properties becomes difficult
Solution Approach 1:
The patent replaces mechanical phase detection methods with optical detection. The optical detector uses light transmission properties to identify phase changes in the pericritical fluid, eliminating the need for complex mechanical sensors that would be difficult to implement in the high-temperature, high-pressure engine environment.
Solution Approach 2:
The patent introduces an intermediary optical detection system that indirectly measures phase properties through light transmission characteristics. Rather than directly measuring pressure, temperature, or density, the system uses optical properties as a mediator to infer phase state, simplifying monitoring while maintaining accuracy.
2Productivity
If phase state control is implemented, then engine operations are optimized, but system complexity increases
Solution Approach 1:
The patent implements a feedback control system where the optical detector continuously monitors phase state and provides signals to the controller. The controller automatically adjusts engine parameters to maintain optimal phase conditions, creating a closed-loop system that optimizes performance without requiring complex manual intervention.
Solution Approach 2:
The patent designs the control system to serve multiple functions: the optical detector not only identifies phase changes but also provides data for performance optimization, and the controller manages both phase state maintenance and engine parameter adjustment. This multi-functionality reduces overall system complexity despite the added control capabilities.
