Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing simulation systems are used to simulate hydrogen production by water electrolysis, then partial processes can be simulated, but the complete process involving power system, chemical system, and control cannot be simulated
Solution Approach 1:
The simulation system is divided into three independent simulation units: a first simulation unit for the power system, a second simulation unit for the chemical system, and a controller unit. Each unit can be developed and tested independently, then integrated through the data interaction unit to achieve complete process simulation without requiring complete system redesign.
Solution Approach 2:
A data interaction unit is introduced as an intermediary component to enable communication and data exchange between the first simulation unit, second simulation unit, and controller unit. This mediator handles data conversion and coordination, allowing the integrated simulation of the complete hydrogen production process while managing system complexity.
2Measurement precision
If multiple simulation units are integrated to simulate complete process, then simulation accuracy improves, but data interaction and coordination become complex
Solution Approach 1:
The data interaction unit is designed with universal functionality to handle multiple types of data exchange between different simulation units and the controller. It provides standardized interfaces and data conversion capabilities that work across all components, reducing the need for custom integration logic and simplifying data coordination while maintaining high simulation accuracy.
3Manufacturing precision
If simulation step sizes differ between first simulation unit and second simulation unit, then each unit can operate at optimal resolution, but coordination timing becomes problematic
Solution Approach 1:
The data interaction unit implements periodic data exchange between the first simulation unit and second simulation unit, allowing each to operate at their optimal simulation step sizes. The controller unit coordinates these periodic exchanges, enabling high-resolution simulations in both units without requiring synchronized time steps, thus avoiding time loss while maintaining precision.
