Engineering Contradiction Analysis
1Reliability
If a charging infrastructure is equipped in large parking garages and areas, then the need for sector coupling and control of charging processes is met, but the economic incentives are low due to low utilization and high downtimes
Solution Approach 1:
The charging infrastructure is divided into modular charging modules that can be independently connected to a common head assembly. Each module can serve vehicles independently, and the modular design allows for flexible configuration and maintenance without shutting down the entire system, thereby maintaining high utilization rates while ensuring reliable charging process control.
2Quantity of substance
If multiple charging points are equipped in parking garages, then charging capacity is increased, but the technical complexity for each charging point increases
Solution Approach 1:
The head assembly serves as a universal component that can connect to and control multiple different charging modules. The standardized interface and common control unit allow the same head assembly to manage various types of charging modules, reducing the technical complexity at each individual charging point while enabling multiple charging points to be deployed.
