Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If various cooling air rectifying members, baffle plates, and guide grooves are provided in cooling air inlets, outlets, and battery case inner surfaces to maintain temperature uniformity, then temperature difference between battery modules is reduced, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent merges the housing structure with the cooling air guide function by forming guide grooves directly on the housing inner surface. This integration eliminates the need for separate cooling air rectifying members and baffle plates, reducing device complexity while maintaining the ability to control cooling air flow and maintain temperature uniformity across battery modules.
Solution Approach 2:
The housing structure serves multiple functions: it provides mechanical support for battery modules and simultaneously acts as a cooling air guide through integrated guide grooves. This multi-functionality reduces the number of separate components needed for both structural support and thermal management, thereby reducing device complexity without compromising temperature control.
2Temperature
If various cooling air rectifying members and support parts are added to cool battery modules uniformly, then temperature uniformity is improved, but weight and manufacturing cost increase
Solution Approach 1:
The patent combines the housing structure with cooling air guidance functionality by forming guide grooves directly on the housing inner surface. This integration eliminates the need for additional separate cooling components, thereby reducing the overall weight of the battery case while maintaining effective cooling air distribution and temperature uniformity across battery modules.
3Temperature
If cooling air flow rate is increased to cool battery modules with small gaps, then cooling performance is improved, but cooling fan power consumption increases
Solution Approach 1:
The patent applies local quality by forming guide grooves at specific locations on the housing inner surface where cooling air needs to be directed. These grooves locally channel cooling air through the gaps between battery modules, improving cooling effectiveness in critical areas without requiring a substantial increase in overall cooling air flow rate, thereby reducing cooling fan power consumption.
Solution Approach 2:
The guide grooves act as intermediaries that efficiently direct cooling air through the battery module gaps. By providing these intermediate guiding structures, the system achieves effective cooling with optimized air flow paths, reducing the energy required by the cooling fan compared to direct high-flow cooling without guidance structures.
4Temperature
If numerous cooling air rectifying members and support parts are used, then cooling performance is improved, but assembly time and manufacturing cost increase
Solution Approach 1:
The patent merges the housing structure with cooling air guidance functionality by forming guide grooves directly on the housing inner surface. This integration eliminates the need for separate cooling air rectifying members and support parts, significantly reducing the number of components that need to be assembled. Consequently, assembly time and manufacturing cost are reduced while maintaining effective cooling performance through the integrated guide grooves.
