Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If system integration (SI) development is performed to build a PMS with components from different manufacturers, then the PMS can integrate diverse energy storage devices, but development man-hours and costs increase significantly
Solution Approach 1:
The gateway engine is designed with universal data mapping capabilities that can handle multiple communication protocols (Modbus TCP, Modbus RTU, BACnet IP, BACnet MS/TP) through a single unified interface. This multi-functional design allows the PMS to integrate diverse energy storage devices from different manufacturers without requiring separate integration development for each protocol, thereby reducing development man-hours while maintaining high adaptability
Solution Approach 2:
The gateway engine acts as an intermediary layer between the PMS and various energy storage devices. It provides automatic data mapping and protocol conversion, mediating between different communication standards and the PMS internal interface. This intermediary function eliminates the need for custom SI development for each device type, reducing development time while enabling broad integration capability
2Productivity
If demand controller disconnects loads to manage peak demand, then power consumption is controlled, but manufacturing processes and quality may be affected
Solution Approach 1:
The system implements self-service through automatic data mapping and protocol recognition. The gateway engine automatically identifies communication protocols and maps data without manual configuration, enabling the system to serve itself during integration. This automation reduces the need for manual intervention and maintains system reliability during operations
Solution Approach 2:
The system incorporates feedback mechanisms where the gateway engine continuously monitors communication protocols and data flow from energy storage devices. This feedback enables dynamic adjustment of data mapping and protocol handling, ensuring reliable operation while managing power demand. The feedback loop allows the system to respond to changing conditions without compromising manufacturing process continuity
