Solution Overview
Problem
Existing autonomous cleaning devices struggle to accurately map and clean areas with complex geometries, such as corners and boundaries, leading to incomplete cleaning and inefficient navigation.
Innovation Solution
The method involves detecting a second surface media area during room mapping, entering a boundary drawing mode, determining the distance to the wall, and scanning the boundary to draw a detailed map of the second surface media area, enhancing the cleaning device's ability to navigate and clean complex areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the autonomous cleaning device draws the room map by ignoring the second surface media area during wall-following mode, then the room map drawing continues without interruption, but the second surface media area (such as carpets) is not cleaned
Solution Approach 1:
The patent segments the cleaning process into two distinct phases: room map drawing phase (where carpets are temporarily ignored to maintain drawing efficiency) and boundary drawing mode (where carpets are specifically targeted). This segmentation allows the system to optimize for different objectives in different phases, resolving the contradiction between drawing efficiency and cleaning coverage.
Solution Approach 2:
The patent performs preliminary room map drawing by ignoring carpets, establishes the overall layout first, and then performs a second pass in boundary drawing mode to clean the previously ignored carpet areas. This preliminary action approach ensures complete cleaning coverage without compromising the initial mapping efficiency.
2Ease of operation
If the autonomous cleaning device enters boundary drawing mode to clean the second surface media area, then the cleaning coverage is improved, but the cleaning process requires additional mode switching and time
Solution Approach 1:
The patent performs preliminary room map drawing before entering boundary drawing mode. By establishing the overall layout first, the system can efficiently plan and execute the boundary drawing phase, minimizing unnecessary movements and reducing the time penalty associated with mode switching.
Solution Approach 2:
The patent maintains continuous useful action by seamlessly transitioning between room map drawing mode and boundary drawing mode. The boundary drawing mode is activated only when necessary (when carpets are detected), and the system continues to draw the map and clean areas without complete interruption, maintaining overall process continuity.
3Measurement precision
If the autonomous cleaning device scans the near-wall boundary of the second surface media area in the opposite direction, then the boundary mapping precision is improved, but the navigation complexity increases
Solution Approach 1:
The patent inverts the scanning direction when drawing boundaries of the second surface media area. Instead of continuing in the original wall-following direction, the device scans in the opposite direction along the boundary. This inversion technique improves boundary mapping precision by providing better geometric constraints, and the patent manages the increased navigation complexity through systematic control logic that activates this mode only during boundary drawing operations.

AI summary
The present disclosure relates to a regional map drawing method, a computer readable storage medium, and an electronic device. The method includes: when an automatic cleaning device draws a room map along a wall in a first surface medium region, if a second surface medium region is detected, ignoring the second surface medium region and continuing to draw the room map; after the room map is completely drawn, controlling the automatic cleaning device to enter a boundary drawing mode for the second surface medium region, and determining a distance between a near-wall boundary of the second surface medium region and a wall surface; and if the distance is within a preset range, controlling the automatic cleaning device to scan the near-wall boundary of the second surface medium region in a direction opposite to a wall-edge cleaning direction.
