Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If charging stations are permanently connected to power grid infrastructure, then reliable power supply is ensured, but installation flexibility and deployment speed are reduced
Solution Approach 1:
The charging station employs dynamic power sourcing that can switch between grid connection mode and battery assembly mode. The system adapts its power supply configuration based on operational needs, allowing it to be permanently installed with grid connection for reliability, or deployed temporarily using only the battery assembly for flexibility. This dynamic adaptability resolves the contradiction between reliable power supply and installation flexibility.
2Device complexity
If charging stations use single power source, then system complexity is reduced, but power output flexibility and charging speed options are limited
Solution Approach 1:
The charging station is designed with multi-functionality to operate with multiple power sources: it can use the power grid as a single power source, the onboard battery assembly as a single power source, or combine both power sources simultaneously. This universal design allows the system to adapt to different operational requirements and provides flexible power output options without requiring complex additional infrastructure.
3Device complexity
If charging stations operate independently, then system simplicity is maintained, but energy distribution efficiency and utilization rate decrease
Solution Approach 1:
The charging station merges with the power grid infrastructure and can combine multiple power sources (grid power and battery assembly power) to operate. This merging enables the station to participate in a networked system where energy can be distributed efficiently across multiple stations, improving overall utilization rates while maintaining operational simplicity through standardized interfaces and control protocols.
