Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If driver intervention is required for inputting charging information and payment, then system reliability is improved through human verification, but ease of operation deteriorates due to driver alighting and manual input requirements
Solution Approach 1:
The charging robot autonomously performs vehicle identification, position recognition, charging connection, and payment processing without requiring driver intervention. The system uses onboard sensors and communication modules to automatically complete the entire charging workflow, transforming a manual process into an automated self-service operation.
Solution Approach 2:
The patent replaces manual driver actions with automated robotic systems. The charging robot uses position recognition devices to detect vehicle location, communication modules to exchange data with the vehicle and payment systems, and automated mechanical arms to connect charging cables, substituting all mechanical driver operations with automated systems.
2Measurement precision
If multiple systems (CCTV, motion sensor bollard, separate payment application) are installed for vehicle identification, obstacle detection, and payment, then measurement precision and safety are improved, but device complexity deteriorates
Solution Approach 1:
The patent integrates vehicle identification, position recognition, obstacle detection, charging control, and payment processing into a single charging robot system. The position recognition device simultaneously performs vehicle location detection and obstacle identification, while the communication module handles both vehicle communication and payment transactions, merging multiple functions into one unified system.
Solution Approach 2:
The charging robot is designed as a multi-functional device that can perform vehicle identification, position recognition, obstacle detection, charging connection, and payment processing. The position recognition device serves dual purposes for both vehicle location and obstacle detection, and the communication module handles multiple communication tasks, embodying universal functionality.
3Reliability
If separate motion sensor bollard and application systems are installed for obstacle detection and payment, then reliability of individual functions is improved, but ease of manufacture deteriorates due to increased installation requirements
Solution Approach 1:
The patent combines obstacle detection capabilities and payment processing functions into the charging robot itself. The position recognition device integrated in the robot performs obstacle detection, and the communication module handles payment transactions, eliminating the need for separate motion sensor bollards and dedicated payment applications, thereby simplifying installation while maintaining functional reliability.
Data Source
AI summary
A charging robot includes a memory storing computer-executable instructions, at least one processor that accesses the memory and executes the instructions, an output device, and a first position recognition device that identifies a vehicle approaching a charging specification. The processor determines at least one of a first distance between the vehicle identified by means of the first position recognition device and the charging robot, a first movement direction of the vehicle, or a first movement speed of the vehicle, or any combination thereof and charges the vehicle, based on that a position of the vehicle is included in a charging position which is a position at which the charging robot is able to charge the vehicle, based on the at least one of the first distance, the first movement direction, or the first movement speed, or the any combination thereof.
