Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the coolant delivery pipe is arranged in the conventional manner, then the cooling system can function, but the pipe cost increases and space utilization deteriorates
Solution Approach 1:
The second transition section extends in the first direction (perpendicular to the cooling plates) rather than only in the plane of the cooling plates, creating a three-dimensional arrangement that reduces in-plane space occupation while maintaining cooling functionality
Solution Approach 2:
The liquid cooling joint is divided into multiple transition sections (first, second, and third transition sections) with distinct functions, allowing optimized spatial arrangement and reducing overall pipe length and cost
2Volume of stationary object
If the distance between liquid cooling joints is reduced, then space utilization improves, but the bending radius of external cooling pipes becomes insufficient
Solution Approach 1:
The second transition section extends perpendicular to the cooling plates in the first direction, utilizing the third dimension to achieve adequate bending radius for external cooling pipes while maintaining compact in-plane footprint
Solution Approach 2:
The liquid cooling joint has an asymmetric structure where the second transition section extends in a different direction (first direction perpendicular to cooling plates) compared to other sections, optimizing both space utilization and pipe routing

AI summary
A box body assembly and a battery pack are provided in the present application. The box body assembly (100) includes a box body and liquid cooling joint groups. The box body comprises a first cooling plate (11) and a second cooling plate (12). The liquid cooling joint groups include a first liquid cooling joint (21) and a second liquid cooling joint (22). The second liquid cooling joint includes a first transition section, a second transition section, and a third transition section. A distance between an orthographic projection of the first liquid cooling joint on a plane where the second cooling plat is located and an orthographic projection of the first transition section on the plane where the second cooling plate is located is D1, a distance from the first transition section to a side edge is D2, and D2 is greater than D1, so as to reduce space and cost on a front panel.
