Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a centralized charging system is used, then charging capacity is concentrated and manageable, but the system cannot efficiently serve multiple parking locations simultaneously
Solution Approach 1:
The charging system is divided into a master charging station and multiple distributed charging posts. The master station handles centralized control, payment, and power distribution, while individual charging posts are distributed across multiple parking locations. This segmentation allows the system to serve multiple locations simultaneously while maintaining centralized management capabilities.
2Productivity
If charging infrastructure is distributed across multiple locations, then parking and charging can occur simultaneously at different spots, but load management becomes more difficult
Solution Approach 1:
The master charging station continuously monitors the status, power consumption, and availability of all distributed charging posts. Based on this real-time feedback, the master station dynamically adjusts power distribution, manages load balancing, and coordinates charging sessions across multiple locations. This feedback mechanism enables efficient load management despite the distributed nature of the infrastructure.
3Ease of operation
If payment and parking services are integrated at the same station, then user convenience is improved, but system complexity increases
Solution Approach 1:
The master charging station integrates multiple services including payment processing, parking management, and charging control into a single unified interface. Users can handle all these functions through one station, eliminating the need to interact with separate systems. This merging of services improves user convenience while the centralized architecture manages the underlying complexity.
4Adaptability or versatility
If voltage conversion is included at charging posts, then compatibility with different vehicle types is improved, but the complexity of individual posts increases
Solution Approach 1:
The voltage conversion functionality is extracted from the distributed charging posts and centralized at the master charging station. The master station handles all voltage conversion and power transformation, while the individual charging posts are simplified to contain only the essential charging interface and local monitoring components. This extraction reduces the complexity of individual posts while maintaining vehicle compatibility through the master station's conversion capabilities.
