Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional positioning methods are used for robot docking, then the system complexity is low, but the docking precision and accuracy deteriorate
Solution Approach 1:
The positioning system is segmented into multiple independent positioning circuits (first positioning circuit, second positioning circuit, third positioning circuit) distributed at different locations. Each circuit independently measures distance to the robot, and the results are combined to calculate the robot's position through triangulation, thereby improving measurement precision while keeping each individual circuit relatively simple
Solution Approach 2:
The patent introduces positioning circuits as intermediary components that facilitate distance measurement between the robot and charging pile. These circuits act as mediators by transmitting positioning messages and calculating time delays, enabling accurate position determination without requiring direct complex interaction between the robot and charging pile control systems
2Productivity
If the robot moves quickly to the charging pile, then the charging time is reduced, but the risk of collision increases
Solution Approach 1:
The system implements continuous feedback through real-time position tracking. The positioning circuits continuously measure the robot's position and provide feedback to the control system. Based on this feedback, the robot can dynamically adjust its speed and trajectory, allowing fast movement when safe and slow movement when approaching the docking point, thereby maintaining both high productivity and safety
Solution Approach 2:
The robot's movement parameters (speed, direction) are made dynamic rather than static. The system continuously calculates the robot's position and adjusts movement parameters in real-time based on the calculated position and distance to the charging pile, enabling the robot to optimize its path and speed dynamically to balance charging efficiency and collision avoidance
3Reliability
If the robot moves slowly to the charging pile, then collision risk is reduced, but the docking time increases
Solution Approach 1:
Continuous position feedback enables the system to determine when the robot is on a safe collision-free path versus when it needs to slow down. The feedback mechanism allows the robot to maintain higher speeds during safe segments of the journey and only reduce speed when necessary, optimizing the balance between safety and time efficiency
4Measurement precision
If multiple positioning circuits are used to improve positioning accuracy, then the docking precision is improved, but the device complexity increases
Solution Approach 1:
The positioning function is segmented across multiple independent circuits rather than using one complex centralized system. Each positioning circuit is relatively simple, performing basic distance measurement and message transmission, while the complexity of combining results is managed through standardized triangulation algorithms
Solution Approach 2:
Each positioning circuit is designed to be universal and multi-functional, capable of performing distance measurement, message transmission, and position calculation. This universality reduces overall system complexity by using identical standardized components rather than specialized circuits for each function
