Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If traditional recharging solutions are used, then recharging functionality is provided, but device complexity and cost increase
Solution Approach 1:
The recharging unit is divided into distinct functional components: a hollow supporting and containment body for housing the cable, a receiving seat for the electrical connector, and a coiled charging cable. This segmentation allows each component to be optimized independently while maintaining overall simplicity and reliability
Solution Approach 2:
The electrical connector is received within the hollow supporting and containment body, which itself is integrated into the vehicle's existing structure. The coiled cable is nested within the containment body, allowing compact storage while maintaining full functionality
2Ease of operation
If more space is allocated for recharging equipment, then connector access and cable management improve, but available vehicle space decreases
Solution Approach 1:
The charging cable is designed in a coiled configuration that allows dynamic expansion when needed for connection and automatic retraction to a compact form when not in use. The receiving seat allows the connector to be easily accessed and removed when required
Solution Approach 2:
The hollow supporting and containment body utilizes three-dimensional space efficiently by creating a nested structure that houses the cable and connector components vertically rather than requiring extensive horizontal space in the engine compartment
3Ease of manufacture
If a fixed connector design is used, then manufacturing is simpler, but adaptability to different recharging standards is reduced
Solution Approach 1:
The receiving seat is designed with a generic cup-shaped structure that can accommodate different types of electrical connectors. The hollow supporting and containment body provides a universal mounting solution that can be adapted to various connector standards without requiring complex customization
Solution Approach 2:
The receiving seat geometry can be modified through parameter changes in the molding process to accommodate different connector shapes and sizes, allowing the same basic structure to serve multiple connector types while maintaining manufacturing simplicity
