Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no control mechanism for state-of-health is implemented, then the electrolysis apparatus can operate freely, but the progression of deterioration cannot be managed and business planning becomes difficult
Solution Approach 1:
The system changes operational parameters (current, voltage, flow rate, temperature) based on the target state-of-health value to control deterioration. The control parameter calculating unit adjusts these parameters dynamically to maintain the apparatus within desired health thresholds while enabling business planning.
Solution Approach 2:
The system implements a feedback loop where the actual state-of-health is continuously monitored and compared against the target state-of-health value. The control unit adjusts operational parameters based on this feedback to prevent excessive deterioration, enabling reliable long-term operation planning.
2Reliability
If control parameters are adjusted to slow deterioration, then state-of-health is improved, but hydrogen production efficiency may be reduced
Solution Approach 1:
The system dynamically adjusts control parameters based on real-time state-of-health monitoring and target values. Rather than using fixed conservative parameters, the system optimizes parameters dynamically to balance deterioration control with hydrogen production efficiency, allowing maximum productivity within health constraints.
Solution Approach 2:
The control parameter calculating unit adjusts multiple operational parameters (current, voltage, flow rate, temperature) in combination to achieve the target state-of-health while minimizing impact on hydrogen production. This multi-parameter optimization allows maintaining efficiency while controlling deterioration.
3Adaptability or versatility
If users can customize target state-of-health values, then adaptability to different business needs is improved, but system complexity increases
Solution Approach 1:
The system allows users to pre-set target state-of-health values based on their specific business needs and requirements. This preliminary configuration enables the control system to automatically adjust parameters according to user-defined goals without requiring complex real-time decision-making interfaces.
Solution Approach 2:
The control parameter calculating unit automatically computes and adjusts operational parameters based on the user-defined target state-of-health value, without requiring continuous user intervention. The system serves itself by autonomously translating user preferences into optimal control parameters.
