Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If battery containers are made large to increase charge and discharge capacity, then energy storage capacity is improved, but transportation and installation become extremely cumbersome
Solution Approach 1:
The battery system is divided into multiple standardized battery containers that can be independently transported and installed. Each container houses battery racks with series-connected batteries, allowing the overall system to be assembled from manageable modular units rather than requiring movement of extremely large single-unit batteries.
2Quantity of substance
If multiple battery containers are connected to increase capacity, then energy storage is improved, but installation process becomes complex and time-consuming
Solution Approach 1:
Battery racks are pre-assembled with batteries connected in series within each container before delivery to the installation site. This preliminary configuration reduces on-site complexity, as workers only need to connect pre-configured containers rather than assembling individual batteries and managing complex wiring during installation.
Solution Approach 2:
The battery containers are designed with standardized interfaces and configurations that can be universally connected in various arrangements. This standardization allows flexible system expansion while maintaining consistent installation procedures, reducing the need for custom process design for each expansion scenario.
3Quantity of substance
If battery containers are made large to accommodate more batteries, then energy density is improved, but post-positioning mobility becomes extremely cumbersome
Solution Approach 1:
The system uses multiple standardized-sized containers rather than one or few extremely large containers. This segmentation maintains high energy density through efficient battery rack configurations while ensuring each container remains manageable for repositioning and relocation after installation.
4Ease of manufacture
If conventional battery containers are used, then manufacturing simplicity is maintained, but adaptability for additional connections and expansion is hindered
Solution Approach 1:
The battery containers incorporate standardized connection interfaces and modular designs that enable easy expansion and additional connections. The universal design allows new containers to be integrated into existing systems without requiring custom modifications, maintaining manufacturing simplicity while significantly improving adaptability.
Solution Approach 2:
The system design allows dynamic expansion by enabling addition of new battery containers to existing configurations. The standardized interfaces and modular architecture support flexible system evolution, allowing the battery system to adapt to changing energy storage requirements while maintaining consistent manufacturing processes.
