Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a custom mounting structure is designed to align with battery and vehicle features, then the battery can be mounted to the vehicle body, but the design and machining difficulties of both the vehicle and battery are increased
Solution Approach 1:
The patent introduces a mounting frame as an intermediary component between the battery and vehicle body. The mounting frame includes a first mounting portion that connects to the vehicle body and a second mounting portion that connects to the battery, serving as a mediator that simplifies the overall mounting structure while ensuring reliable connection.
Solution Approach 2:
The mounting structure is segmented into distinct components: the mounting frame, the first mounting portion for vehicle body connection, and the second mounting portion for battery connection. This segmentation allows each component to be optimized independently, reducing overall design and machining complexity.
2Quantity of substance
If the side frame portion is positioned to make full use of underbody space, then the battery capacity can be increased, but the side frame portion is more exposed to corrosion and impacts
Solution Approach 1:
The middle frame portion acts as a protective intermediary that shields the side frame portions from direct exposure to corrosive environments and impacts. The middle frame portion is positioned between the side frame portions and the external environment, reducing harmful factor exposure while allowing the side frame portions to extend into underbody spaces for increased battery capacity.
3Adaptability or versatility
If the side frame portion extends in the length direction of the underbody longitudinal beam, then the space utilization rate is improved, but the dimension in width direction becomes smaller increasing breakage risk
Solution Approach 1:
The mounting frame integrates the side frame portions and middle frame portion into a unified structural system. The middle frame portion connects the side frame portions, creating a combined structure that distributes mechanical loads and reduces breakage risk in the side frame portions while maintaining their extended configuration for optimal space utilization.
Solution Approach 2:
The middle frame portion provides structural support and protection to the side frame portions before they are subjected to external forces. This beforehand cushioning effect reduces the risk of breakage by distributing stresses and preventing concentrated loads on the narrower side frame portions.
