Cleaning Device Path Planning to Prevent Carpet Wetting During Mopping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices wet carpets when mopping, affecting user experience.
Innovation Solution
A control method for cleaning devices that prioritizes cleaning target carpet regions first and maintains an unwetted cleaning component during this process, followed by cleaning non-target regions, with adaptive operation modes and path planning to minimize carpet wetting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cleaning device uses a wet cleaning component to clean the floor, then the cleaning effect is improved, but the carpet gets wet which deteriorates user experience
Solution Approach 1:
The cleaning process is segmented into distinct phases: carpet cleaning phase (dry cleaning only) and floor cleaning phase (wet cleaning allowed). The cleaning component's operation mode is segmented based on the surface type being cleaned, enabling dry cleaning for carpets and wet cleaning for hard floors, thus resolving the contradiction between cleaning effectiveness and carpet protection
Solution Approach 2:
The cleaning component applies different cleaning qualities to different regions. When detecting carpet regions, the cleaning component switches to dry cleaning mode with reduced or zero moisture output. When detecting hard floor regions, it switches to wet cleaning mode with full moisture output, thereby achieving effective cleaning of floors while preventing carpet wetting
2Productivity
If the cleaning device cleans all regions including carpet areas, then the overall cleaning coverage is improved, but the carpet wetting probability increases
Solution Approach 1:
The cleaning device incorporates real-time feedback through sensors that detect surface type (carpet vs. hard floor) and cleaning component status (wet vs. dry). Based on this feedback, the control system dynamically adjusts the cleaning component's operation mode and the device's navigation path, enabling full area coverage while preventing carpet wetting through continuous monitoring and adaptive response
Solution Approach 2:
The cleaning device dynamically transitions between different operation modes based on real-time conditions. The cleaning component can switch between dry and wet modes, and the device can adjust its cleaning path dynamically to avoid wetting carpets while ensuring complete coverage of hard floors, making the system adaptable rather than static
3Object-affected harmful factors
If the cleaning device prioritizes carpet region cleaning first, then the carpet dryness is improved, but the overall cleaning time increases
Solution Approach 1:
The cleaning device performs preliminary identification and mapping of carpet regions before executing the cleaning task. By pre-segmenting the cleaning area into carpet zones and non-carpet zones, the device can plan an optimized cleaning path that efficiently sequences dry cleaning of carpets followed by wet cleaning of floors, reducing overall cleaning time while ensuring carpet dryness through advance preparation

AI summary
The present application disclose a control method for a cleaning device and related devices. After receiving a first cleaning instruction, the cleaning device is controlled to first clean a target carpet region, and then to clean a non-target region in an operation region other than the target carpet region, and a cleaning component of the cleaning device is unwetted while the target carpet region is cleaned.
