Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a charging station system is implemented to recharge electric vehicles, then vehicle battery recharging capability is improved, but system complexity increases due to need for access authorization, object tracking, and safety management mechanisms
Solution Approach 1:
A stationary computer acts as an intermediary between sensors, charging stations, and vehicles. It receives sensor data, determines object information, manages access authorization, and controls charging station components, thereby centralizing complexity in a dedicated management unit rather than distributing it across all system elements
Solution Approach 2:
The system continuously monitors the area around charging stations using sensors, tracks objects and vehicles, and uses this feedback information to dynamically authorize access, update risk levels, and control charging operations. This closed-loop feedback mechanism enables adaptive safety management without requiring overly complex predetermined control logic
2Reliability
If access authorization and object tracking mechanisms are implemented, then safety and security of charging operations are improved, but processing time and computational resources increase
Solution Approach 1:
The system performs preliminary actions by pre-authorizing vehicles before they reach the charging station, tracking objects in advance to assess potential risks, and preparing access control decisions beforehand. This allows the system to have authorization and safety assessments ready before actual charging begins, reducing processing delays during critical operations
Solution Approach 2:
The safety and authorization system is segmented into independent functional modules: vehicle identification, object detection, risk assessment, and access control. Each module processes specific tasks independently, allowing parallel processing and reducing overall processing time compared to a monolithic system

AI summary
A plurality of vehicle charging stations and a plurality of stationary sensors with respective fields of view can be disposed within an area. A stationary node computer including a first processor and a first memory and communicatively can be coupled to the charging station and the stationary sensors, the first memory storing instructions executable by the first processor such that the stationary computer is programmed to authorize a request from a vehicle to access the charging station; identify an object, detected in the area in data from one or more of the stationary sensors, to be tracked with respect to the vehicle; wherein the object to be tracked with respect to the vehicle is identified based on a type of the object, an attribute of the object and an attribute of the vehicle; and transmit data about the object to the vehicle.
