Cleaning cloth switching device and method, and sweeping and mopping robot
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sweeping and mopping robots face issues with stains from cleaning cloths contaminating carpets due to strong water absorption, limiting their cleaning effectiveness on different surfaces.
Innovation Solution
A cleaning cloth switching device with a mop comprising first and second cleaning portions made of different materials, controlled by a roller assembly and detection members to adapt to various surfaces, ensuring effective stain removal without carpet contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a cleaning cloth with strong water absorption capacity is used, then water absorption capacity is improved, but stains on the cleaning cloth contaminate the carpet
Solution Approach 1:
The cleaning cloth is divided into multiple independent cleaning portions with different materials. Each portion can be independently selected and switched to the bottom surface based on the cleaning object, allowing the robot to use different portions for different surfaces (e.g., hard floor vs. carpet) to avoid stain contamination while maintaining water absorption capacity when needed
Solution Approach 2:
The cleaning cloth is designed to be dynamically switchable between different cleaning portions through the roller assembly. The system can adjust which portion contacts the bottom surface in real-time based on detection of the cleaning surface type, transforming a static single-material cloth into a dynamic multi-material system that adapts to different cleaning scenarios
2Ease of manufacture
If a single material cleaning cloth is used, then manufacturing simplicity is maintained, but cleaning effectiveness on different surfaces is limited
Solution Approach 1:
The cleaning cloth assembly is designed to perform multiple functions by incorporating different cleaning portions made of different materials. This universal design allows a single cleaning cloth assembly to effectively clean various surfaces including hard floors, carpets, and other surfaces by switching to the appropriate portion, thereby achieving multi-functionality without requiring separate cleaning cloths for each surface type
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances cleaning versatility by preventing water stains from reaching carpets while maintaining effective floor cleaning, improving the applicability of the robot on diverse surfaces.
Implementation Method 1
the roller assembly rolls so as to drive the first cleaning portion or the second cleaning portion to move to the bottom of the housing
