Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heat pump or electric heater is added to an electric vehicle, then heating capability is improved, but device complexity and product size increase
Solution Approach 1:
The heating element is integrated directly into the battery pack structure, merging the thermal management function with the structural framework. This eliminates the need for separate heat pumps or heaters, reducing device complexity while maintaining heating capability.
Solution Approach 2:
The battery pack structure serves multiple functions: it provides structural support, houses electrical components, and acts as the heating system. The heating elements are embedded within the battery pack, allowing the same structure to perform both structural and thermal management functions.
2Temperature
If a heat pump or electric heater is added to an electric vehicle, then heating capability is improved, but product size increases
Solution Approach 1:
The heating elements are nested within the battery pack structure itself, utilizing the existing space between battery cells and structural components. This nesting approach allows the heating system to occupy no additional volume beyond what is already allocated for battery packaging.
Solution Approach 2:
By combining the heating function with the battery pack structure, the system eliminates the need for separate heating components that would increase product size. The heating elements are embedded within the same volume that houses the battery cells.
3Volume of moving object
If the heating plate is made compact, then product size is minimized, but gap formation between heating plate and electrical terminal increases
Solution Approach 1:
The bus bar is designed with flexible or adjustable sections that can adapt to variations in heating plate position and dimensions. This dynamic design allows the electrical connection to maintain reliable contact even when the heating plate is compact or experiences thermal expansion during operation.
Solution Approach 2:
The bus bar configuration uses asymmetric routing and connection points that accommodate the compact heating plate geometry. The electrical terminal arrangement is specifically designed to bridge potential gaps created by the compact heating element layout, ensuring reliable connectivity despite space constraints.
