Side Brush Bristle Positioning in Robot Mopping Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cleaning robots, the bristles of the side brush assembly often rotate and exceed the designated area during mopping mode, causing contamination and affecting user experience by touching external objects or the mopping assembly, and the driving wheel, and failing to be cleaned by the mopping assembly timely.
Innovation Solution
A controller is used to limit the target bristle of the side brush assembly within a designated area or separate it from the ground, ensuring it does not exceed the mopping area, thereby preventing contamination and maintaining the cleanliness of the surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the side brush assembly is provided with long bristles to improve cleaning coverage, then the cleaning ability is enhanced, but the bristles exceed the robot body and cause contamination to clean surfaces and affect appearance
Solution Approach 1:
The side brush assembly is designed to be rotatable relative to the robot body, allowing the bristles to dynamically adjust their position. During mopping mode, the side brush rotates to a predetermined angle that limits bristle extension beyond the robot body, while during sweeping mode, it rotates to a different angle for optimal cleaning performance. This dynamic adjustment resolves the contradiction by adapting bristle position to different operational requirements.
Solution Approach 2:
The system changes the operational parameter of the side brush assembly by controlling its rotation angle based on the working mode. The controller receives signals about the current mode (sweeping or mopping) and adjusts the side brush rotation angle accordingly, thereby changing the spatial parameter of bristle extension to prevent contamination while maintaining cleaning effectiveness.
2Device complexity
If the side brush assembly rotates freely during mopping mode, then the structure is simple, but the bristles affect the appearance and may damage external objects or the mopping assembly
Solution Approach 1:
The side brush assembly incorporates a rotation mechanism that allows it to dynamically change its angular position. During mopping mode, it rotates to a predetermined angle that prevents bristles from interfering with external objects or the mopping assembly, thereby improving reliability without significantly complicating the overall structure.
Solution Approach 2:
The controller receives feedback about the working mode and automatically adjusts the side brush rotation angle accordingly. This feedback mechanism ensures that the side brush is positioned appropriately for each mode, preventing damage to external objects and the mopping assembly while maintaining relatively simple structural design.
3Adaptability or versatility
If the side brush bristles are kept long to clean hard-to-reach areas, then cleaning versatility is improved, but the bristles cannot be cleaned by the mopping assembly timely and may pollute clean surfaces
Solution Approach 1:
The rotatable side brush assembly allows long bristles to be dynamically positioned during mopping mode to a predetermined angle where they are limited from exceeding the robot body. This ensures that even though the bristles are long for versatility, they can be controlled to prevent pollution of clean surfaces while still being accessible for cleaning by the mopping assembly.
Solution Approach 2:
The system changes the rotation angle parameter of the side brush assembly based on working mode. During mopping mode, the angle is adjusted to limit bristle extension, preventing pollution while maintaining the benefit of long bristles for cleaning versatility in other modes.

AI summary
A cleaning robot, a bristle control method and a bristle control device, and a computer storage medium are provided. The cleaning robot includes a robot body, an side brush assembly disposed on the robot body, and a controller disposed on the robot body and configured to control a target bristle of the side brush assembly to be limited in a designated area. In embodiments of this application, the target bristle of the side brush assembly is limited in the designated area to prevent, as much as possible, the target bristle from exceeding out of the cleaning robot and affecting the appearance of the cleaning robot.
