Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple fuel cell systems are integrated into a power plant system, then power generation capacity and reliability are improved, but system complexity and control difficulty increase
Solution Approach 1:
The fuel cell power plant system is divided into multiple independent power units, each containing one or more fuel cell systems. Each power unit can operate independently, allowing the system to maintain power generation capability even if one unit fails, thus improving reliability while managing complexity through modular architecture.
Solution Approach 2:
The controller is designed to universally manage multiple power units with different configurations of fuel cell systems. The controller can adapt to various operation modes (power generation, standby, maintenance, emergency stopped) and monitor multiple parameters across all units, providing a unified control interface that simplifies operation despite system complexity.
2Reliability
If comprehensive monitoring and control mechanisms are implemented, then system reliability and performance are improved, but device complexity and cost increase
Solution Approach 1:
The controller continuously monitors the operation status of all power units and receives feedback on various parameters. Based on this feedback, the controller automatically adjusts system operation, switches between operation modes, and triggers maintenance or emergency stop procedures when fault conditions are detected, ensuring reliable operation without requiring complex manual intervention systems.
Solution Approach 2:
The monitoring circuitry automatically detects fault conditions and the controller autonomously manages system state transitions between operation modes. The system performs self-diagnosis and self-management, reducing the need for additional complex external control mechanisms while maintaining high reliability through automated monitoring and response.
3Reliability
If real-time monitoring of fault conditions is implemented, then system safety and reliability are improved, but measurement and detection difficulty increase
Solution Approach 1:
The monitoring circuitry acts as an intermediary between the complex fuel cell systems and the controller. It consolidates and processes information from multiple sensors and subsystems, translating raw data into meaningful fault condition indicators that the controller can easily interpret and act upon, thereby simplifying fault detection despite the complexity of the underlying systems.
