Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If multiple fuel cell systems are installed in a vehicle to increase power supply capacity, then the power supply capability is improved, but the system efficiency deteriorates due to lack of optimized control
Solution Approach 1:
The control system dynamically adjusts the power generation allocation among multiple fuel cell systems based on real-time operational data including deterioration degrees, power generation time periods, activation counts, and stop counts. This dynamic optimization ensures that the system operates at peak efficiency while meeting power demands, preventing energy loss despite having multiple systems running.
Solution Approach 2:
The system monitors and responds to changes in operational parameters such as deterioration degree, power generation time period, number of activations, and number of stops. By adjusting power generation allocation based on these parameter changes, the system maintains optimal efficiency across varying operating conditions while utilizing multiple fuel cell systems.
2Power
If power generation is distributed among multiple fuel cell systems, then the power supply capacity is increased, but the deterioration of individual systems accelerates
Solution Approach 1:
The control system applies differentiated control strategies to each individual fuel cell system based on its specific operational state and deterioration level. Systems with lower deterioration degrees are allocated higher power generation tasks, while systems showing signs of wear are given reduced loads or maintenance priorities, optimizing both capacity and longevity.
Solution Approach 2:
The system continuously monitors operational data from each fuel cell system including deterioration degree, power generation time period, activation count, and stop count. This feedback is used to adjust power generation allocation in real-time, preventing any single system from being overworked and extending the overall system lifespan while maintaining power supply capacity.
3Productivity
If all fuel cell systems operate at full capacity to meet power demand, then the power supply efficiency is improved, but the deterioration degree increases
Solution Approach 1:
The control system selectively activates only the necessary number of fuel cell systems based on current power demands and individual system states. Rather than running all systems at full capacity, it optimizes the combination of active systems to meet demand efficiently while minimizing overall deterioration across the fleet.
Solution Approach 2:
The system dynamically determines the optimal number and configuration of active fuel cell systems based on real-time conditions. This dynamic adjustment allows the system to maintain high power supply efficiency when needed while reducing the operational burden on individual systems to control deterioration, balancing productivity and reliability.
