Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the robot uses simple navigation methods to return to the charging pile, then the system complexity is reduced, but the positioning accuracy and docking precision deteriorate
Solution Approach 1:
The positioning system is segmented into multiple independent positioning circuits distributed at different locations within the charging pile. Each positioning circuit independently transmits request messages and calculates distance based on time delay, allowing the robot to determine its position through triangulation using multiple reference points, thereby achieving high positioning accuracy without requiring a complex centralized system
Solution Approach 2:
The patent introduces positioning circuits as intermediary components that facilitate communication between the robot and the charging pile control system. These circuits transmit request messages and receive response messages, enabling precise position calculation through time delay measurement without requiring direct complex interaction between the robot and the main control system
2Measurement precision
If the robot uses complex navigation algorithms to improve positioning accuracy, then the positioning precision is improved, but the time required for returning to charge increases
Solution Approach 1:
The positioning circuits continuously transmit request messages at preset intervals before the robot actually needs to dock, maintaining an updated position map in advance. This allows the robot to receive real-time position information and calculate the optimal return path proactively, reducing the time spent on complex real-time calculations during the actual return journey
Solution Approach 2:
The system implements feedback mechanisms where the charging pile continuously provides position information to the robot through response messages containing distance and position data. The robot uses this feedback to dynamically adjust its navigation path, ensuring efficient and accurate return to the charging pile without requiring overly complex onboard algorithms
3Device complexity
If the robot navigates without precise position information, then the navigation system is simpler, but the docking efficiency and charging reliability deteriorate
Solution Approach 1:
The robot autonomously determines its position by receiving request messages from multiple positioning circuits, calculating time delays, and computing its coordinates using the intersection of circular trajectories. This self-service positioning capability eliminates the need for complex external navigation infrastructure while ensuring high docking efficiency through accurate real-time position awareness
