Solution Overview
Problem
Existing cleaning robots face inefficiencies in edge cleaning due to complex structures and increased soiling of wet cleaning heads, particularly when dealing with dry and wet garbage, and often require additional recycling systems, leading to reduced cleaning effectiveness and increased maintenance.
Innovation Solution
A cleaning device with a dry cleaning module and an auxiliary wet cleaning module, where the main and auxiliary cleaning assemblies are positioned behind the dry cleaning module, allowing for dry sweeping followed by wet mopping, and the auxiliary assembly extends beyond the edge to ensure comprehensive edge cleaning without gaps, eliminating the need for additional recycling systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wet cleaning head is used to clean both dry and wet garbage, then the cleaning effect is improved, but the structure becomes complex due to the need for recycling systems and scraping bars
Solution Approach 1:
The cleaning device is divided into separate functional modules: a dry cleaning module with rolling brushes for dry garbage, and a wet cleaning module with cleaning pads for wet garbage. This segmentation allows each module to be optimized for its specific function without requiring complex recycling systems, resolving the contradiction between cleaning effectiveness and structural complexity
Solution Approach 2:
The patent extracts the dry cleaning function into a separate module positioned in front of the wet cleaning module. The dry cleaning module handles dry garbage independently, preventing it from soiling the wet cleaning head, thus eliminating the need for scraping bars and recycling systems while maintaining comprehensive cleaning effectiveness
2Device complexity
If a wet cleaning head is used without a recycling system, then the structure is simplified, but the cleaning head soils more easily and requires constant cleaning
Solution Approach 1:
The dry cleaning module performs preliminary cleaning of dry garbage before the wet cleaning module operates. By positioning the dry cleaning module in front and having it sweep dry garbage into the dust box first, the wet cleaning head is prevented from contacting dry garbage, eliminating soiling without requiring recycling systems or constant maintenance
3Adaptability or versatility
If the auxiliary cleaning assembly extends beyond the edge of the body for edge cleaning, then edge cleaning capability is improved, but cleaning-missed areas may occur between main and auxiliary assemblies
Solution Approach 1:
The cleaning device employs different cleaning assemblies with specialized functions: the main cleaning assembly covers the central area, while the auxiliary cleaning assembly extends beyond the body edge specifically for edge and corner cleaning. The rolling brushes are positioned to sweep toward the dust box, creating overlapping cleaning zones that eliminate missed areas while maintaining edge cleaning capability
4Reliability
If the dry cleaning module is positioned in front of the wet cleaning module, then dry garbage is prevented from soiling wet cleaning heads, but the overall device size increases
Solution Approach 1:
The patent merges the dry cleaning module and wet cleaning module into a single integrated cleaning device with shared components such as the dust box, control system, and power supply. The modules are positioned sequentially along the length of the device, allowing compact arrangement that minimizes overall size while maintaining the functional separation needed to prevent soiling of the wet cleaning head

AI summary
The present disclosure disclosed a cleaning device, comprises a body, a main cleaning module and an auxiliary cleaning module, the main cleaning module is disposed on the body, the first lift structure is configured to drive the main cleaning assembly to ascend and descend, the auxiliary cleaning assembly is non-swingable relative to the body, at least part of the auxiliary cleaning assembly is always disposed outside the edge of the body, to clean along the edge, under the driving of the first lift structure, the auxiliary cleaning module ascends or descends synchronously with the main cleaning assembly, enabling the main cleaning assembly and the auxiliary cleaning assembly to ascend and descend to stay in the lifting position and the mopping position synchronously. Cleaning along the edge while prevent the cleaning-missed area from existing between the main cleaning assembly and the auxiliary cleaning assembly, enhancing the overall cleaning effect.
