Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a thermal management member is placed between two battery modules to regulate temperatures, then temperature control efficiency is improved, but device complexity increases
Solution Approach 1:
The thermal management member combines multiple functions: it serves as a thermal management component with thermally conductive surfaces for temperature regulation, while simultaneously functioning as a load-bearing structure supporting the battery modules. This merging of thermal management and structural support functions reduces overall device complexity despite adding thermal management capability.
Solution Approach 2:
The thermal management member is designed as a multi-functional component that performs both thermal regulation and mechanical support. The first and second thermally conductive surfaces regulate temperatures of adjacent battery modules, while the member's load-bearing capacity provides structural support, eliminating the need for separate structural components.
2Volume of moving object
If battery modules are arranged on opposite sides of a thermal management member, then packaging efficiency is improved, but manufacturing complexity increases
Solution Approach 1:
The battery pack is segmented into modular units with battery modules arranged on opposite sides of the thermal management member. This segmentation allows for standardized module designs that can be manufactured independently and assembled systematically, reducing overall manufacturing complexity despite the sophisticated spatial arrangement.
Solution Approach 2:
The arrangement transitions from conventional single-sided battery module placement to a three-dimensional configuration where modules are positioned on opposite sides of the thermal management member. This dimensional change optimizes space utilization while maintaining manufacturability through standardized interfaces and modular assembly procedures.
3Stability of the object's composition
If a suspension attachment is used to mount the battery pack to the vehicle frame, then mechanical stability is improved, but device complexity increases
Solution Approach 1:
The suspension attachment merges the mounting function with the thermal management structure. The attachment points are integrated into the thermal management member or battery module housings, combining the suspension mounting function with existing structural and thermal management components, thereby minimizing additional complexity.
Solution Approach 2:
The thermal management member and battery module housings serve multiple functions: they provide thermal regulation, structural support, and mounting interfaces for the suspension attachment. This multi-functionality reduces the need for separate dedicated mounting components, balancing stability requirements with device complexity.
