Innovation Solution
The charging station features connection terminals positioned at different surfaces, allowing the boundary wire to be connected in distinct directions, ensuring clear and correct polarity indication, preventing miswiring and facilitating accurate docking and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the charging station uses traditional terminal connection design without clear polarity indication, then the device complexity is reduced, but the ease of operation deteriorates due to difficulty in distinguishing terminals during wire connection
Solution Approach 1:
The patent applies color coding to the terminals of the charging station, where different colors indicate different polarities (positive and negative). This allows users to easily distinguish between terminals during wire connection without adding complex identification mechanisms, directly resolving the contradiction between ease of operation and device complexity
Solution Approach 2:
The patent segments the terminal identification function by providing distinct visual markers (colors) for each terminal type. This segmentation allows users to quickly identify the correct terminal for connection without having to understand complex electrical characteristics, improving ease of operation while maintaining simple device structure
2Reliability
If the charging station lacks clear terminal polarity indication, then the manufacturing process is simplified, but the reliability deteriorates due to high likelihood of incorrect wire connection
Solution Approach 1:
By incorporating color-coded terminals, the patent provides clear polarity indication that prevents incorrect wire connections. This simple visual enhancement significantly improves connection reliability without complicating the manufacturing process, as color coding can be applied during standard production
Solution Approach 2:
The patent implements preliminary action by pre-marking terminals with colors before the user performs the connection operation. This advance preparation eliminates the need for users to analyze or determine polarity during installation, ensuring correct connection and improving reliability while requiring minimal additional manufacturing steps
3Measurement precision
If the charging station uses simple terminal design without directional connection capability, then the device complexity is low, but the measurement precision deteriorates due to inaccurate boundary recognition by the robot
Solution Approach 1:
The patent introduces asymmetry in the terminal design by positioning terminals at different locations on the charging station body and assigning different colors to different terminals. This asymmetric design provides directional information that helps the robot accurately recognize boundaries and orientation, improving measurement precision without requiring complex sensing systems
Solution Approach 2:
The color coding of terminals provides visual directional information that assists the robot in accurately identifying the correct connection points and understanding the spatial orientation of the charging station. This simple visual enhancement improves boundary recognition precision while maintaining device simplicity
