Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If energy storage systems are configured in independent container units, then each system can be independently controlled and contained, but the systems must be controlled individually which increases operational complexity and reduces efficiency
Solution Approach 1:
The patent merges multiple independent container units into a single integrated energy storage system. Multiple battery containers are connected within one system framework, allowing centralized control through a unified control system rather than requiring separate control for each container. This reduces operational complexity while maintaining the containment and control capabilities of individual units.
Solution Approach 2:
The control system is designed with universal functionality to manage multiple battery containers simultaneously. The single control system can interface with and control various components across different containers, providing multi-functional control capabilities that eliminate the need for separate control systems for each container unit.
2Ease of manufacture
If communication lines are not pre-configured with connection terminals, then system assembly is simpler, but communication stability between components deteriorates
Solution Approach 1:
Connection terminals are pre-configured and built into the communication lines during the manufacturing stage. This preliminary action ensures that when the system is assembled, the communication connections are already established and stable, eliminating the need for complex field wiring while guaranteeing reliable communication between control components.
Solution Approach 2:
The connection terminals act as intermediary elements that facilitate stable communication between different system components. These pre-configured terminals provide standardized interfaces that ensure reliable electrical and data connections, serving as mediators between the control container and battery containers without requiring complex custom wiring arrangements.
3Device complexity
If battery containers cannot be easily expanded, then system configuration is simpler, but scalability and adaptability to different energy storage requirements are reduced
Solution Approach 1:
The energy storage system is divided into modular battery containers that can be independently added or removed. Each container is a self-contained unit with standardized interfaces, allowing the system to be segmented into discrete modules. This segmentation enables easy expansion by simply adding more container units while maintaining system simplicity through standardized configurations.
Solution Approach 2:
The system configuration is made dynamic and adaptable through modular design. The number and arrangement of battery containers can be changed based on energy storage requirements, allowing the system to evolve and scale. This dynamic configuration capability enables adaptability to different applications while maintaining operational simplicity through consistent modular interfaces.
