Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the calorific value of gas source changes, then the gas use efficiency changes, but the gas pressure and flow become unstable
Solution Approach 1:
The system implements a closed-loop feedback mechanism where the calorific value detection device continuously monitors the calorific value of gas, and the pressure regulation device automatically adjusts pressure regulation parameters based on the detected changes. This feedback loop ensures that when calorific value changes affect gas use efficiency, the system responds by adjusting pressure to maintain stable operation, thereby resolving the contradiction between efficiency changes and pressure stability.
Solution Approach 2:
The system dynamically changes the pressure regulation parameters (such as opening degree of regulation valves, pump frequency, or valve position) in response to detected calorific value changes. By adjusting these parameters adaptively, the system compensates for the impact of calorific value variations on gas use efficiency while maintaining stable gas pressure and flow, thus resolving the technical contradiction.
2Reliability
If pressure regulation parameters are manually adjusted, then gas pressure can be controlled, but the system cannot adapt to real-time calorific value changes
Solution Approach 1:
The system enables self-service operation where the pressure regulation device autonomously adjusts pressure regulation parameters based on real-time calorific value detection without requiring manual intervention. The detection device continuously monitors calorific value, and the control system automatically processes this information to adjust pressure parameters, making the system both reliable for pressure control and adaptable to real-time changes.
Solution Approach 2:
The system replaces manual mechanical adjustment with an automated control system that uses detection devices and control algorithms to adjust pressure regulation parameters. This substitution of manual operation with an intelligent control system enables both reliable pressure control and real-time adaptability to calorific value changes.
3Productivity
If the calorific value of gas is high, then the gas use efficiency is high, but when the calorific value is low, the gas use efficiency decreases
Solution Approach 1:
The system implements dynamic pressure regulation that adapts to varying calorific values. When calorific value is high, the system adjusts pressure parameters to optimize for high efficiency; when calorific value is low, it adjusts parameters to maintain stable operation. This dynamic adjustment ensures that gas use efficiency is maximized under high calorific value conditions while maintaining reliability and stability under low calorific value conditions.
