Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cleaning agents are delivered into the combustion chamber, then cleaning effectiveness is improved, but component damage risk increases due to high temperature
Solution Approach 1:
The system performs preliminary temperature monitoring and waits for the combustion chamber to cool down to a safe temperature before delivering cleaning agents. The control unit receives temperature information from the temperature sensor and only controls the driver mechanism to deliver cleaning agents when the temperature is at or below the predetermined temperature, preventing thermal damage to components.
Solution Approach 2:
The system uses a temperature sensor to continuously monitor the temperature within the combustion chamber and provides feedback to the control unit. The control unit adjusts the cleaning agent delivery based on this temperature feedback, creating a closed-loop control system that ensures cleaning only occurs when temperature conditions are safe.
2Object-affected harmful factors
If temperature monitoring and control systems are added, then component protection is improved, but device complexity increases
Solution Approach 1:
The system uses the turbine engine's own operational characteristics (temperature changes after shutdown) to perform the protection function. Instead of adding complex active cooling or heating systems, the system simply monitors the natural temperature decline and triggers cleaning when appropriate, leveraging the engine's self-cooling property.
