Solution Overview
Problem
Existing cleaning robots face inefficiencies in cleaning areas near walls due to displacement mechanisms that require avoidance troughs, leading to debris accumulation and increased user burden.
Innovation Solution
A cleaning device with a rotating plate and eccentrically mounted cleaning plate, driven by dual mechanisms for rotation and displacement, which avoids debris accumulation and expands cleaning coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If an oscillating mechanism with displacement avoidance trough is used to enable the cleaning rotating plate to move for displacement, then the cleaning coverage is improved, but debris accumulates in the avoidance trough increasing user burden
Solution Approach 1:
The patent removes the avoidance trough structure from the cleaning device. Instead of creating a dedicated space for the oscillating mechanism's movement trace, the design allows the cleaning rotating plate to oscillate directly on the cleaning surface without requiring a separate avoidance area, thereby eliminating the debris accumulation problem while maintaining cleaning coverage
Solution Approach 2:
Rather than designing a static avoidance trough and accepting debris accumulation, the patent inverts the approach by making the cleaning rotating plate itself movable through oscillation. This allows the cleaning surface to be dynamically adjusted to cover wall areas without creating a separate problematic structure
2Ease of operation
If a displacement avoidance trough is formed in the robot bottom to accommodate the movement trace of the cleaning rotating plate, then the oscillating mechanism can function properly, but the device complexity increases and aesthetics deteriorate
Solution Approach 1:
The patent extracts and eliminates the avoidance trough from the device structure. By removing this unnecessary structural element, the design simplifies the overall construction, reduces manufacturing complexity, and improves aesthetic appearance while still enabling the oscillating mechanism to function through direct mounting of the cleaning rotating plate
Solution Approach 2:
The cleaning rotating plate serves dual functions: it performs cleaning operations and simultaneously provides the oscillating movement mechanism. This eliminates the need for separate structural components like avoidance troughs, reducing device complexity while maintaining functionality
3Productivity
If the cleaning rotating plate is mounted to move for displacement to clean wall areas, then the productivity is improved, but the loss of time for user maintenance increases
Solution Approach 1:
The cleaning rotating plate is designed to be removable and washable by the user. This self-service design allows users to easily clean the plate themselves without requiring professional maintenance or complex disassembly procedures, thereby reducing the time and effort needed for maintenance while maintaining high cleaning productivity

Implementation Method 1
a transmission structure (5), an input end of which is in transmitting connection with the first drive mechanism (2), an output end of which is in transmitting connection with the cleaning plate (4) to drive the cleaning plate (4) to rotate
Implementation Method 2
the cleaning plate (4) being eccentrically mounted on the rotating plate (3), so that the rotating plate (3) drives, through rotation thereof, the cleaning plate (4) to move for displacement

AI summary
A cleaning device includes a chassis defining a trough; a first drive mechanism; a rotating plate fitted in the trough, a cleaning plate eccentrically mounted on the rotating plate, the rotating plate being provided with a transmission structure, an input end of the transmission structure being in transmitting connection with the first drive mechanism, an output end of the transmission structure being in transmitting connection with the cleaning plate to drive the cleaning plate to rotate; a second drive mechanism connected with the rotating plate for driving the rotating plate to rotate and thereby driving the cleaning plate to move for displacement. The trough allows the rotating plate to be fitted therein and the trough is shielded by the rotating plate to prevent contaminants from passing through the trough to get into the cleaning device, reducing occurrence of a situation of contaminant depositing and hiding in the transmitting connection site.
