Virtual Boundary Mapping for Adaptive Lawn Mower Edge Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automatic lawn mowers often fail to clean grass in parts of the work area due to complex and changing environments, leading to inefficient mowing operations and the need for reworking.
Innovation Solution
Generate a working map by recording position information of path points and determining boundary attributes to create a virtual boundary, allowing for different working modes based on these attributes, ensuring efficient mowing operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single preset working mode is used for boundary mowing, then the device complexity is reduced, but the mowing quality and completeness deteriorate
Solution Approach 1:
The patent applies dynamics by making the working mode adjustable and adaptive rather than fixed. The control unit dynamically selects different working modes (first working mode for extending beyond boundary, second working mode for mowing along boundary) based on the detected boundary attribute configuration information, allowing the system to adapt to different boundary conditions and improve mowing quality without excessive complexity
Solution Approach 2:
The patent applies local quality by configuring different boundary attributes for different segments of the work area boundary. Each boundary segment can have its own attribute configuration information, allowing the automatic lawn mower to apply different working modes to different local areas based on their specific characteristics, thereby improving overall mowing quality
2Ease of operation
If a single preset working mode is used for boundary mowing, then the ease of operation is improved, but the productivity deteriorates due to reworking
Solution Approach 1:
The patent applies feedback by detecting boundary attribute configuration information during the mowing process and using this information to adjust the working mode. The control unit continuously monitors boundary conditions and feedback from sensors, then automatically selects the appropriate working mode to prevent incomplete mowing and eliminate the need for reworking, thereby improving productivity while maintaining ease of operation
Solution Approach 2:
The patent applies preliminary action by detecting and configuring boundary attributes before completing the mowing operation. The system identifies boundary characteristics in advance and pre-plans the appropriate working mode selection, preventing incomplete mowing before it occurs and avoiding the need for subsequent reworking passes
3Adaptability or versatility
If boundary attributes are configured for different path points, then the adaptability to complex environments is improved, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the work area boundary into multiple path points and configuring boundary attributes for different segments. Each path point or boundary segment can have its own attribute configuration information, allowing the system to handle complex and changing environments by processing boundary conditions in manageable segments rather than as a single complex whole

AI summary
Embodiments of the application provide a method for generating a working map, an operation method, a control method, and a related apparatus. The method for generating a working map includes the following operations. The automatic operation apparatus is controlled to move, to record position information of multiple path points on a movement path of the automatic operation apparatus. Boundary attribute configuration information is received, and boundary attributes of at least a part of the path points are determined according to the boundary attribute configuration information. A working map including position information of multiple boundary points and boundary attributes of at least a part of the boundary points is generated. The position information of multiple boundary points are determined according to the position information of multiple path points, the boundary attribute of the boundary point is determined according to the boundary attribute of the path point, multiple boundary points are configured to indicate a virtual boundary surrounding a preset area, and when the automatic operation apparatus performs operations along the virtual boundary, working modes when the automatic operation apparatus moves to boundary points corresponding to different boundary attributes are different. This solution may improve work efficiency of the automatic operation apparatus.
