Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a non-modular cooled battery pack encloses several cell assemblies in one large liquid tank, then the cooling coverage is improved, but the pack becomes bulky and heavy
Solution Approach 1:
The battery pack is divided into multiple modular battery modules, each with its own integrated cooling channels. This segmentation allows each module to be independently cooled without requiring a large centralized liquid tank, reducing overall pack weight while maintaining adequate cooling coverage across all cell assemblies.
2Volume of moving object
If a modular cooled battery pack uses independent liquid containers for each cell assembly, then the pack size is reduced, but the specific parameters such as overall size, shape, voltage, and current become fixed and not adjustable
Solution Approach 1:
The battery module design incorporates universal standardized interfaces for electrical connections and mechanical assembly. The case frame structure with standardized mounting positions and the modular architecture allow different numbers of modules to be combined to create battery packs with various voltages, currents, and physical dimensions, making the system adaptable to different application requirements while maintaining a compact form factor.
3Ease of manufacture
If conventional cooled battery modules have fixed parameters, then the manufacturing process is simplified, but it becomes difficult to adapt to various application fields
Solution Approach 1:
The battery system employs a dynamic modular architecture where standardized battery modules can be flexibly configured in series or parallel arrangements to achieve different voltage and current specifications. The case frame structure includes standardized mounting interfaces that allow easy reconfiguration for different application fields, maintaining manufacturing simplicity through standardization while enabling adaptability through modular combinatorics.
