Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If air cooling method is used for battery thermal management, then the cooling structure is simple, but the cooling effect is insufficient when battery temperature is extremely high

Solution Approach 1:

The cooling system is segmented into multiple independent cooling channels formed by alternating arrangement of first cooling plates and second cooling plates. Each cooling plate has through-holes that create separate fluid flow paths, allowing the system to be divided into modular units that can be independently optimized for thermal management efficiency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cooling plates are nested between battery packs in a stacked configuration, with multiple cooling plates interleaved with battery packs to form a compact integrated structure. This nesting approach maximizes heat dissipation surface area within limited space while maintaining structural compactness.

Inventive Principle:

Solution Approach 1:

The cooling plates are merged with the battery pack structure to form an integrated assembly. The cooling channels are formed within the cooling plates themselves rather than requiring separate cooling components, combining the thermal management function with the structural support function in a single integrated design.

Inventive Principle:

Solution Approach 1:

The cooling plates are nested between battery packs in a compact stacked arrangement, with each cooling plate fitting into the interstices of the battery pack assembly. This nesting configuration achieves efficient heat dissipation through multiple cooling surfaces while maintaining a compact overall height by utilizing the vertical space between battery components.
