Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the number and size of ignition promoter droplets are not controlled, then the system is simple to operate, but fuel combustion becomes incomplete and emissions increase
Solution Approach 1:
The system employs feedback control where sensors monitor combustion parameters and the controller adjusts droplet generation accordingly. The controller receives feedback signals and modifies the number and size of droplets to optimize combustion while preventing excessive emissions, resolving the contradiction between combustion reliability and system complexity.
Solution Approach 2:
The system dynamically changes parameters such as droplet number, droplet size, and injection timing based on operating conditions. By adjusting these parameters in real-time, the system achieves complete combustion and reduces emissions without requiring a fundamentally complex system architecture.
2Reliability
If too much ignition promoter material is added, then combustion is improved, but particulate matter generation increases
Solution Approach 1:
The feedback control system monitors combustion quality and adjusts the amount of ignition promoter material accordingly. When combustion is sufficient, the system reduces the promoter material to minimize particulate matter generation, while maintaining reliable combustion when needed.
Solution Approach 2:
The system applies partial action by providing just enough ignition promoter material to achieve complete combustion rather than excessive amounts. This optimized approach ensures combustion reliability while minimizing harmful particulate matter emissions.
3Loss of energy
If droplet size is not controlled, then the system is easier to operate, but thermal efficiency decreases
Solution Approach 1:
The system uses feedback control to monitor thermal efficiency parameters and adjusts droplet size accordingly. By controlling droplet size within an optimal range, the system maximizes thermal efficiency while the feedback mechanism manages the complexity of droplet generation.
Solution Approach 2:
The system dynamically adjusts droplet size parameters based on operating conditions to optimize thermal efficiency. This parameter control ensures energy is not lost through incomplete combustion or excessive promoter material, while the feedback system manages the complexity of precise droplet control.
