Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a battery module is formed as a unibody with a fixed number of battery cells, then the structural integrity is maintained, but the overall capacity cannot be reconfigured in response to changing requirements
Solution Approach 1:
The battery pack is divided into multiple independent battery cell assemblies, each with its own cover part and cooling member. These assemblies can be independently installed or removed from the battery pack, allowing flexible reconfiguration of the overall capacity without affecting the structural integrity of individual modules.
Solution Approach 2:
The battery pack design allows dynamic adjustment of the number of battery cell assemblies installed based on changing requirements. The frame structure with guide parts and insertion holes enables easy addition or removal of assemblies, providing adaptability while maintaining structural stability through standardized interfaces.
2Temperature
If battery cells are connected in series to form a battery cell assembly, then the voltage requirements are met, but the cooling efficiency is insufficient without dedicated cooling mechanisms
Solution Approach 1:
The cooling member is integrated into the cover part structure, merging the cooling function with the protective housing. This combination provides effective cooling for the battery cells while avoiding the need for separate cooling systems, thus improving thermal management without proportionally increasing overall structural complexity.
Solution Approach 2:
The cooling member is positioned to directly contact the battery cell assembly at specific locations where heat generation occurs. This localized cooling approach targets the thermal management needs of individual cell assemblies, improving cooling efficiency without requiring a complex system-wide cooling infrastructure.
3Quantity of substance
If multiple battery cell assemblies are installed in the battery pack, then the overall capacity increases, but the heat dissipation becomes more challenging
Solution Approach 1:
Each battery cell assembly has its own dedicated cooling member within the cover part, providing localized thermal management. This segmentation of cooling functions ensures that heat dissipation is handled effectively at each assembly level, preventing heat accumulation even when multiple assemblies are installed in the battery pack.
