Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a battery pack is mounted on a vehicle with a convex installation floor or round-shaped components present, then the battery pack can be installed, but dead spaces are generated between the battery pack and the installation site, deteriorating space efficiency
Solution Approach 1:
The cooling unit is designed with convex and concave parts that correspond to the installation environment. The convex parts fit into concave spaces formed by round-shaped components or convex installation floors, eliminating dead spaces and improving space efficiency without requiring complex adaptive mounting structures
Solution Approach 2:
The cooling unit extends in the vertical direction with convex and concave parts, utilizing the third dimension to accommodate installation site irregularities. This vertical dimensionality allows the battery pack to fit into spaces with convex floors or round components without compromising horizontal space utilization
2Volume of moving object
If the cooling unit includes convex and concave parts to accommodate installation site irregularities, then space efficiency is improved, but the structural complexity of the cooling unit increases
Solution Approach 1:
The cooling unit with convex and concave parts serves multiple functions: it provides thermal management for the battery modules, acts as a mounting structure that accommodates various installation site irregularities, and eliminates dead spaces. This multi-functionality reduces the need for separate components and simplifies the overall system
Solution Approach 2:
The cooling unit integrates the thermal management function with the structural mounting function. By combining these functions into a single component with convex and concave parts, the design eliminates the need for separate mounting brackets or adapters, reducing overall structural complexity despite the enhanced geometry
