Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a stationary fast-charging station is established, then charging infrastructure is provided, but the permitting process takes up to two years
Solution Approach 1:
The charging station is implemented as a mobile unit mounted on a trailer that can be transported to different locations, transforming the static charging infrastructure into a dynamic, relocatable system that bypasses lengthy permitting requirements for permanent structures
Solution Approach 2:
The charging infrastructure is divided into modular components including battery packs, charging ports, and mounting equipment that can be independently assembled and deployed, allowing rapid setup without requiring complete infrastructure installation
2Productivity
If multiple electric vehicles are serviced simultaneously, then charging capacity increases, but device complexity increases
Solution Approach 1:
The mobile charging station incorporates multiple charging ports and battery packs that can simultaneously service multiple vehicles of different types, creating a universal charging solution that handles various vehicle requirements through standardized interfaces
Solution Approach 2:
Multiple battery packs and charging systems are combined into a single integrated mobile unit, consolidating what would otherwise be separate charging stations into one cohesive platform that serves multiple vehicles simultaneously
