Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the number of battery cells is increased, then the heat dissipation capacity is improved, but the assembly process becomes complicated and installation efficiency decreases
Solution Approach 1:
The liquid-cooled plate is divided into multiple modular plate bodies that can be independently manufactured and then assembled together. Each plate body can be separately produced and then quickly connected using the protrusion-recess structure, allowing parallel manufacturing and simplified assembly processes even as the overall system scales to accommodate more battery cells.
2Temperature
If the number of liquid-cooled plates is increased, then the heat dissipation performance is improved, but the assembly process becomes complicated
Solution Approach 1:
Multiple plate bodies are merged into a unified liquid-cooled plate structure through the protrusion-recess connection mechanism. This allows the system to achieve the heat dissipation performance of multiple plates while maintaining a simplified assembly process that treats them as a single integrated component, eliminating the need for complex multi-plate assembly procedures.
Solution Approach 2:
The protrusion and recess structures act as intermediary connection elements that facilitate the assembly process. These features serve as mechanical guides and connectors that simplify the joining of multiple plate bodies, reducing assembly complexity while enabling the construction of large-scale liquid-cooled plate systems.
3Ease of manufacture
If conventional chassis splicing structure is used, then the liquid-cooled plates can be connected, but installing shift and misalignment occur
Solution Approach 1:
The connection interface uses asymmetric protrusion and recess structures that are complementary to each other. This asymmetric design provides built-in alignment guidance, ensuring that plate bodies can only be assembled in the correct orientation and position, thereby eliminating installing shift and misalignment while maintaining ease of manufacture.
