Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sweeping robots with single roller brushes are inconvenient to switch between sweeping modes for different surfaces, requiring manual removal and installation of different brushes.
Innovation Solution
A roller brush component with an adjusting mechanism that includes a rotatable frame, a hard-bristle roller brush, and a soft-bristle roller brush, where the adjusting mechanism, comprising an elastic element and a cam, allows the brushes to change ground clearance, enabling automatic switching between carpet and floor sweeping modes without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single roller brush is used, then the device structure is simple, but the sweeping mode cannot be switched between different surfaces
Solution Approach 1:
The roller brush is divided into two independent segments: a first roller brush for hard floors and a second roller brush for carpets. These segments are mounted on a rotatable frame that can switch between positions, allowing the device to adapt to different sweeping surfaces without requiring a completely different brush configuration for each surface type.
Solution Approach 2:
The roller brush frame is designed to be rotatable rather than fixed, enabling dynamic switching between different brush configurations. The adjusting mechanism allows the frame to rotate between a first position (hard floor mode) and a second position (carpet mode), providing adaptability while maintaining a relatively simple overall structure.
2Ease of operation
If different roller brushes are used for different surfaces, then the sweeping performance is optimized, but manual removal and installation is required
Solution Approach 1:
The device performs the brush switching operation automatically through its own adjusting mechanism without requiring external manual intervention. The control system activates the adjusting mechanism to rotate the roller brush frame between positions, enabling the device to service itself by switching between hard floor and carpet modes autonomously.
Solution Approach 2:
The rotatable frame design enables automatic switching between different brush configurations. The adjusting mechanism, driven by the control system, rotates the frame to bring the appropriate brush into contact with the surface, eliminating the need for manual removal and installation of brushes.
3Extent of automation
If an adjusting mechanism is added to enable brush switching, then automatic mode switching is achieved, but the device complexity increases
Solution Approach 1:
The adjusting mechanism utilizes a rotatable frame design that provides automatic brush switching through rotational motion. This dynamic configuration allows the mechanism to transition between hard floor and carpet modes by simply rotating the frame to different positions, achieving automation with relatively simple mechanical components rather than complex multi-stage adjustment systems.

AI summary
The embodiments of the present application provide a cleaning device and a roller brush component. The roller brush component includes a mounting base, a roller brush frame, an adjusting mechanism, a first roller brush and a second roller brush. A notch is formed on one side of the mounting base. The roller brush frame is rotatablely connected with the mounting base. The adjusting mechanism is in driving connection with the roller brush frame to drive the roller brush frame to rotate. The first roller brush and the second roller brush are connected with the roller brush frame, and the roller brushes are positioned in the notch. The roller brush frame, the first roller brush and the second roller brush are configured such that the first roller brush and the second roller brush may have different ground clearances during rotation of the roller brush frame. The first roller brush may correspond to a sweeping mode, and the second roller brush may correspond to another sweeping mode. The adjusting mechanism drives the roller brush frame to rotate to enable the first roller brush or the second roller brush to be in contact with the ground, so that the sweeping modes are switched without manual replacement operations such as disassembly and installation.
