Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional obstacle avoidance operations are performed after obstacle addition or removal, then the robot can avoid collisions, but the mowing efficiency is greatly reduced due to unnecessary obstacle avoidance operations
Solution Approach 1:
The system implements feedback by continuously monitoring obstacle information and automatically triggering boundary re-planning when obstacle changes are detected. The upper computer receives real-time obstacle data, determines whether re-planning is needed, and updates the boundary information, creating a closed-loop control system that balances safety and efficiency.
Solution Approach 2:
The system performs preliminary action by pre-establishing boundary information and path planning algorithms that can quickly adapt to obstacle changes. When an obstacle is added or removed, the system has pre-configured mechanisms to automatically update boundary data and recalculate paths, avoiding the need for time-consuming manual intervention during operation.
2Manufacturing precision
If manual boundary re-planning is performed after obstacle changes, then the path planning accuracy is improved, but the time consumption and operational complexity increase
Solution Approach 1:
The system implements self-service by enabling automatic boundary re-planning without manual intervention. When obstacle changes are detected, the upper computer automatically triggers the boundary re-planning process, retrieves updated boundary information, and executes path recalculation, making the system self-sufficient in adapting to environmental changes.
Solution Approach 2:
The system replaces manual mechanical boundary adjustment with automated electronic control. Instead of manually modifying boundary parameters, the system uses electronic algorithms to automatically recalculate boundaries and paths based on updated obstacle information, substituting human operation with computational processes.
3Productivity
If complete automatic correction logic is implemented for boundary processing, then the mowing efficiency is improved, but the system complexity increases
Solution Approach 1:
The system segments the automatic correction logic into distinct functional modules: obstacle change detection, boundary information retrieval, path re-planning algorithm execution, and result display. Each module handles a specific aspect of the correction process, making the overall complex system manageable through modular design and clear separation of concerns.
Solution Approach 2:
The upper computer serves as an intermediary between the mower and the boundary re-planning system. It receives obstacle change notifications, coordinates the boundary re-planning process, and manages data flow between different components, simplifying the control architecture by centralizing the coordination function in a dedicated intermediary device.
