Detachable Wet-Cleaning Module for Adjustable Robot Mopping Width
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning robots are limited to single functions, requiring multiple devices for sweeping and mopping, which occupy space and cause inefficiencies due to structural design limitations, and integrated systems fail to adjust cleaning widths, leading to incomplete cleaning.
Innovation Solution
An automatic cleaning device with a mobile platform featuring a detachable connection between a driving platform and a supporting platform, allowing for a dry-cleaning and wet-cleaning module with a reciprocating cleaning head, enabling adjustable cleaning widths and facilitating maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sweeping robot and mopping robot are combined into integrated cleaning device, then cleaning function is improved, but device complexity increases
Solution Approach 1:
The cleaning device is divided into separate functional modules: a sweeping module and a mopping module. Each module can be independently assembled, disassembled, and maintained. The mopping module includes a mopping cloth that can be detached from the robot body, allowing users to easily replace or clean the mopping cloth without disassembling the entire device.
Solution Approach 2:
The robot body is designed with universal interfaces and standardized connection structures that can accommodate different cleaning modules. The control system and navigation system serve both sweeping and mopping functions, making the base unit multi-functional while allowing specialized modules to be added or removed based on user needs.
2Adaptability or versatility
If mopping module is integrated into robot body, then cleaning function is improved, but ease of repair deteriorates
Solution Approach 1:
The mopping module is designed as a separate, detachable component from the robot body. The mopping cloth can be easily removed and replaced by users without requiring technical expertise. Internal components of the mopping module such as the motor and transmission mechanisms can be independently accessed and replaced.
Solution Approach 2:
The mopping module is extracted as an independent functional unit that can be completely removed from the robot body. This extraction design allows the mopping module to be separately maintained, repaired, or replaced without affecting the sweeping functionality of the robot body.
3Productivity
If mopping cloth width is made equal to robot bottom surface width, then cleaning coverage is improved, but harmful factors increase
Solution Approach 1:
The mopping cloth width and position are made dynamically adjustable rather than fixed. The control system can adjust the mopping cloth width to match the effective sweeping width, ensuring that the mopping cloth only cleans areas that have been previously swept. The position of the mopping module can also be dynamically adjusted during operation.
Solution Approach 2:
The control system uses feedback from sensors and navigation data to dynamically adjust the mopping cloth parameters. The system monitors the sweeping path and width, and automatically adjusts the mopping cloth configuration to ensure proper sequencing - sweeping first, then mopping - preventing the harmful effect of mopping before sweeping.
