Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If boundary edge detection is performed manually or with simple sensors, then the system structure remains simple, but the measurement precision and reliability of boundary detection deteriorates
Solution Approach 1:
The patent introduces a boundary edge detection device as an intermediary component that专门 detects boundary edges and provides detection results to the control unit. This mediator handles the complex detection task, allowing the main robot system to remain relatively simple while achieving high detection precision through the specialized detection device.
Solution Approach 2:
The patent replaces manual mechanical boundary detection with electronic/optical detection systems. The boundary edge detection device uses sensors (such as optical sensors or cameras) to detect boundary edges, substituting manual mechanical methods with automated electronic detection to improve precision while managing system complexity.
2Productivity
If autonomous mobile robots are used for green space processing, then productivity increases, but the difficulty of detecting and measuring boundary edges worsens due to autonomous operation requirements
Solution Approach 1:
The patent implements a feedback mechanism where the boundary edge detection device continuously monitors the robot's position relative to boundary edges and provides real-time feedback to the control unit. The control unit adjusts the robot's movement based on this feedback, enabling autonomous operation while accurately maintaining boundary detection despite the increased complexity of autonomous navigation.
3Ease of operation
If the robot operates autonomously without human intervention, then ease of operation improves, but the reliability of boundary detection and processing deteriorates
Solution Approach 1:
The patent enables the robot to perform self-service through autonomous operation. The control unit automatically controls the robot's movement and processing operations based on boundary detection results, without requiring continuous human intervention. The system maintains reliability by integrating the specialized boundary edge detection device that provides accurate detection data for autonomous decision-making.
