Cleaning Robot Modules With Lifted Mopping and Reciprocating Head
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cleaning robots are limited in their ability to simultaneously sweep and mop effectively, as they often require separate devices and struggle with heavy stains and uneven surfaces, and their cleaning components cannot be lifted or lowered, restricting their mobility.
Innovation Solution
An automatic cleaning apparatus with a mobile platform, integrated dry-cleaning and wet-cleaning modules, and a lifting and lowering structure that allows the cleaning modules to move vertically, enabling comprehensive cleaning and improved surface contact and mobility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cleaning component is always closely attached to the cleaned surface, then the cleaning effect is improved, but the mobility and freedom of movement of the apparatus deteriorates
Solution Approach 1:
The cleaning component is designed to be dynamically adjustable between a lowered cleaning state and a raised movement state. The lifting and lowering structure enables the cleaning component to move vertically, allowing it to be closely attached to the surface during cleaning operations for effective cleaning, and lifted away during movement to reduce resistance and improve mobility.
2Speed
If the mop cloth translates on the ground in a moving manner, then the apparatus can move continuously, but the cleaning efficiency and effectiveness deteriorates due to only single-pass cleaning
Solution Approach 1:
The cleaning component implements periodic reciprocating motion along the cleaning trajectory. Instead of continuous unidirectional movement, the cleaning component moves forward to clean a section, then reciprocates backward to clean the same section again, creating a periodic cleaning pattern that ensures thorough cleaning of heavily soiled areas while maintaining continuous apparatus movement.
3Reliability
If separate ground-sweeping robot and ground-mopping robot are used, then each robot can be optimized for its specific function, but the device complexity and space requirement increases
Solution Approach 1:
The invention merges the ground-sweeping robot and ground-mopping robot into a single integrated apparatus. The cleaning apparatus includes both a dry-cleaning module for sweeping and a wet-cleaning module for mopping, allowing both cleaning functions to be performed by one device rather than requiring separate robots, thereby reducing device complexity and space requirements while maintaining function-specific optimization.
Solution Approach 2:
The cleaning apparatus is designed with multi-functionality, capable of performing both dry cleaning (sweeping) and wet cleaning (mopping) operations. The apparatus includes a dry-cleaning module and a wet-cleaning module with cleaning components that can be lowered to the surface, enabling a single device to handle multiple cleaning tasks that previously required separate specialized robots.
4Duration of action of stationary object
If the cleaning component is always in contact with the surface, then continuous cleaning is maintained, but the resistance during movement increases
Solution Approach 1:
The cleaning component's contact with the surface is dynamically controlled through the lifting and lowering structure. During cleaning operations, the component is lowered to maintain continuous contact for sustained cleaning. During movement between cleaning zones, the component is lifted to reduce friction and movement resistance, enabling more efficient traversal while maintaining cleaning capability when needed.
