Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electric vehicle charging robot systems have complex structures, leading to potential damage during malfunctions and may not efficiently charge vehicles while the robot is being charged, resulting in delayed charging for parked electric vehicles.
Innovation Solution
A robot system with a simple structure utilizing a guide rail, slider, and rotation arm to maximize service reach, equipped with sensors and a controller to manage charging operations, allowing the robot to move around the vehicle and charge it efficiently without requiring separate wheels, thus simplifying the structure and reducing manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electric vehicle charging robot is equipped with a driving unit for unmanned driving, then the robot can autonomously navigate to vehicles, but the structure becomes complicated and the risk of damage during malfunction increases
Solution Approach 1:
The patent extracts the driving unit from the robot system, separating the navigation function from the charging function. The robot is positioned on a fixed guide rail that handles movement, while the robot itself only performs charging operations. This extraction eliminates complex driving components while maintaining autonomous navigation capability through external rail guidance.
Solution Approach 2:
The guide rail acts as an intermediary between the charging station and the robot, handling the complex movement and positioning tasks. The rail system mediates the navigation function, allowing the robot to reach vehicles without requiring its own driving unit, thus simplifying the robot's structure while maintaining autonomous operation.
2Duration of action of stationary object
If the robot moves to the charging station to be charged, then the robot can be recharged, but the electric vehicle in the parking line cannot be charged during this time
Solution Approach 1:
The guide rail system serves multiple functions: it positions the robot for charging at the charging station, enables the robot to reach multiple different vehicles at various locations around the parking area, and facilitates smooth transitions between charging and service modes. This multi-functionality allows continuous vehicle charging service while the robot alternates between charging and serving different vehicles.
Solution Approach 2:
The robot's position and orientation are dynamically adjustable through the guide rail system and rotation mechanism. The robot can dynamically switch between being stationary at the charging station for recharging and moving to various vehicles for charging service, optimizing the balance between robot maintenance and service continuity.
3Ease of manufacture
If the robot uses a simple structure with guide rail and rotation arm, then manufacturing costs are reduced, but the service reach around the vehicle must be maximized
Solution Approach 1:
The patent adds rotational movement as another dimension to the robot's positioning capability. The rotation arm enables the robot to reach different locations around the vehicle (front, rear, left, right sides) without requiring complex multi-axis robotic manipulators. This dimensional addition maximizes service reach while maintaining a simple, cost-effective structure.
