Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual auxiliary input interface is used to collect terrain data and draw working path, then the robot can perform work according to planned path, but the operation process becomes cumbersome and labor-intensive
Solution Approach 1:
The robot performs self-positioning and self-mapping by automatically collecting terrain data through its own movement and processing the data to generate working paths without manual intervention. The system uses the robot's own positioning module and processor to complete the path planning task independently.
Solution Approach 2:
The patent replaces the manual mechanical operation of drawing paths on an input interface with an automated computational system. The processor automatically generates the working path based on collected terrain data, substituting manual mechanical path drawing with algorithmic path generation.
2Loss of information
If cameras and auxiliary equipment are added to acquire terrain data, then the robot can collect terrain information, but the equipment cost and system complexity increase
Solution Approach 1:
The robot's positioning module serves multiple functions: it not only determines the robot's position for navigation but also collects terrain data for path planning. This multi-functional use of the positioning module eliminates the need for separate cameras or specialized sensing equipment.
Solution Approach 2:
The robot uses its own positioning module to simultaneously achieve positioning and terrain mapping functions. The system serves itself by using existing hardware components for multiple purposes, avoiding the need for additional dedicated equipment.
3Adaptability or versatility
If manual auxiliary path planning is performed, then the working path can be customized according to terrain, but the production and use cost increases due to additional equipment and manual labor
Solution Approach 1:
The patent replaces manual path planning with an automated computational algorithm that processes terrain data and generates optimized working paths. This substitution eliminates the need for manual intervention while maintaining the ability to adapt paths to terrain characteristics.
Solution Approach 2:
The robot's processor automatically generates customized working paths based on the collected terrain data, enabling the system to adapt to different terrains without requiring manual path design or additional equipment.

AI summary
Disclosed are a method and system for generating a virtual boundary of a working region of a self-moving robot, and a self-moving robot and a readable storage medium. The method comprises the following steps: acquiring several recording points of a mobile positioning module circling along a patrol path; storing recording points corresponding to the first circle walked in a first storage linked list, and storing the remaining recording points in a second storage linked list; successively retrieving each recording point in the first storage linked list and taking the recording point as a basic coordinate point, and querying the second storage linked list to successively select m recording point groups corresponding to each basic coordinate point; according to each basic coordinate point and the m recording point groups corresponding thereto, respectively acquiring a boundary fitting point corresponding to the basic coordinate point, and forming a boundary fitting point sequence; acquiring boundary points according to the boundary fitting point sequence; and successively connecting the boundary points to generate a virtual boundary of a working region. In the present invention, a virtual boundary is generated according to recording points corresponding to a patrol path, such that human labor costs are reduced and the working efficiency is improved.
