Robot Cleaning System with Automatic Mop Replacement Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaning robots with mopping functions require manual intervention for mop replacement, leading to suboptimal cleaning effectiveness, noise pollution, and user dissatisfaction due to sewage residue and loud cleaning processes.
Innovation Solution
A robot cleaning system with a mop that can automatically switch between operational and replacement states, utilizing a cleaning layer replacement mechanism to facilitate quick, quiet, and pollution-free mop replacement at a base station.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual mop cleaning or replacement is used, then the cleaning robot can maintain cleaning function, but it requires user intervention and is troublesome
Solution Approach 1:
The base station is equipped with an automatic mop cleaning mechanism that includes a cleaning drum and water tank. The cleaning drum rotates to squeeze and clean the mop automatically when the robot returns to the base station, eliminating the need for manual user intervention in mop maintenance
Solution Approach 2:
The patent replaces manual mechanical mop replacement with an automated cleaning system. The cleaning drum uses rotational mechanical action to automatically clean and squeeze the mop, substituting the need for users to manually remove and replace mop heads
2Extent of automation
If automatic water washing solution is used, then manual intervention is reduced, but the cleaning effect is not ideal and sewage residue remains
Solution Approach 1:
The cleaning drum rotates at different speeds and directions to dynamically adjust the cleaning process. The rotation creates varying pressure and friction forces that effectively remove dirt from the mop, improving cleaning effectiveness compared to static cleaning methods
Solution Approach 2:
The base station performs preliminary cleaning of the mop before the robot departs again. By cleaning the mop at the base station after each use, the system prevents sewage residue accumulation and maintains cleaning effectiveness for subsequent tasks
3Ease of manufacture
If conventional cleaning drum rotation method is used, then mop is cleaned through squeezing, but noise is relatively loud affecting user experience
Solution Approach 1:
The patent uses a flexible mop structure that can be effectively cleaned through rotational squeezing. The flexible nature of the mop allows for effective cleaning with lower noise compared to rigid mechanical scraping methods, while maintaining cleaning effectiveness

AI summary
A robot cleaning system includes a cleaning robot, and a base station. The cleaning robot includes: a main body, a mover, and a mopping module, movably connected to the main body and including a replaceable cleaning layer. When the mopping module is in the first state, the cleaning layer is fitted to the working surface, and when it is in the second state, the cleaning layer is separated from the working surface, so that a working surface of the cleaning layer is exposed and is in contact with a cleaning layer removal mechanism. The cleaning robot also includes a driving mechanism configured to drive the mopping module to switch between the first state and the second state; and a controller configured to at least control the driving mechanism to drive the mopping module to switch from the first state to the second state when the cleaning layer needs to be replaced.
