Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a charging robot performs autonomous charging operations, then user convenience is improved, but system reliability deteriorates due to malfunctions in vehicle recognition, cable coupling, and charging management
Solution Approach 1:
The patent implements comprehensive feedback mechanisms including vehicle recognition feedback through camera systems, charging port detection feedback, cable coupling status feedback, and battery level feedback. The control apparatus continuously monitors operation status and provides real-time feedback to adjust charging operations, ensuring reliable autonomous operation while maintaining user convenience.
Solution Approach 2:
The charging robot is designed to perform self-service functions including autonomous navigation to vehicles, self-recognition of charging ports, automatic cable coupling and decoupling, and autonomous charging management. The system independently completes the entire charging process without user intervention, improving convenience while maintaining reliability through automated control.
2Object-affected harmful factors
If the charging robot performs comprehensive safety inspections, then safety is improved, but operation time increases due to obstacle detection and safety function verification
Solution Approach 1:
The patent implements preliminary safety inspections before charging operations begin, including obstacle detection in the operation area, vehicle recognition verification, and charging port accessibility checks. By performing these safety checks in advance, the system ensures safety without significantly increasing overall operation time, as the inspections are integrated into the autonomous navigation and positioning processes.

AI summary
A charging robot control apparatus includes a memory storing computer-executable instructions and at least one processor that accesses the memory and executes the instructions. The at least one processor identifies at least one of a vehicle type of a vehicle or a vehicle information number (VIN) of the vehicle, or any combination thereof by means of a vehicle's number, based on recognizing the vehicle's number, controls a charging robot to perform charging of the vehicle, when a parking state of the vehicle is a parking completion state and receiving a charging request from the vehicle, and controls the charging robot to end the charging of the vehicle, based on a target battery amount of the vehicle.
