Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If ammonia decomposition is performed in the cracker, then hydrogen is produced for the fuel cell, but the ammonia decomposition rate is unstable and residual ammonia remains
Solution Approach 1:
The system performs preliminary actions by predicting future hydrogen consumption amounts based on driving patterns before actually needing the hydrogen. The controller calculates predicted hydrogen consumption amounts at specific future time points and adjusts ammonia supply and cracker conditions in advance, ensuring stable decomposition rates are maintained before fluctuations occur.
Solution Approach 2:
The system dynamically adjusts operating parameters based on real-time conditions. The controller modifies ammonia supply amounts and cracker internal conditions (temperature, pressure) dynamically according to predicted hydrogen consumption patterns, allowing the decomposition rate to adapt continuously rather than remaining fixed, thereby maintaining stability across varying operational demands.
2Productivity
If real-time driving information and driving pattern information are used to predict hydrogen consumption, then ammonia supply can be optimized, but system complexity increases
Solution Approach 1:
The system implements feedback mechanisms by continuously monitoring real-time driving information and comparing it with stored driving pattern information. The controller uses this feedback loop to calculate predicted hydrogen consumption amounts and adjust ammonia supply accordingly, creating a closed-loop control system that optimizes performance while managing complexity through systematic information processing.
Solution Approach 2:
The controller performs preliminary calculations of hydrogen consumption amounts based on analyzed driving patterns before actual hydrogen demand occurs. By pre-processing driving information and predicting future needs, the system reduces the complexity of real-time decision-making while maintaining optimized ammonia supply control.
