Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a complex cooling structure and intensive internal component arrangement are used, then cooling efficiency is improved, but assembly process efficiency and space utilization deteriorate
Solution Approach 1:
The patent merges the cooling structure with the battery module structure by integrating the heat sink directly into the module frame and positioning refrigerant pipes to serve multiple modules simultaneously. This integration reduces the number of separate cooling components and simplifies the assembly process while maintaining effective cooling of battery cells.
2Temperature
If a complex cooling structure and intensive internal component arrangement are used, then cooling efficiency is improved, but space utilization deteriorates
Solution Approach 1:
The patent utilizes three-dimensional space arrangement by positioning refrigerant pipes to extend between battery modules and arranging cooling components in vertical and horizontal dimensions. This multi-dimensional layout optimizes space utilization by efficiently routing cooling pathways through available gaps and surfaces without requiring excessive lateral space.
3Productivity
If a simplified cooling structure is used, then assembly process efficiency is improved, but cooling efficiency deteriorates
Solution Approach 1:
The integrated cooling structure serves multiple functions: the heat sink cools battery cells while the module frame provides structural support, and the refrigerant pipes simultaneously cool multiple battery modules. This multi-functionality allows a simplified structure to achieve effective cooling by maximizing the utility of each component.
4Quantity of substance
If intensive arrangement of internal components and battery modules is used, then capacity is increased, but assembly complexity increases
Solution Approach 1:
The patent divides the battery pack into modular units with standardized battery modules that can be systematically arranged. This segmentation allows for intensive packing of modules to increase capacity while maintaining assembly simplicity through repetitive, standardized module placement and integration with the cooling structure.
