Integrated Roller and Disc Brush Cleaning Head for Mixed Floor Debris
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaning machines can only be equipped with either a roller brush or a disk brush, leading to reduced efficiency and high maintenance costs due to complex replacement processes and limitations in handling various types of floor dirt.
Innovation Solution
A cleaning apparatus integrating a roller brush and a disk brush with a control rod, brush tray, and squeegee, where the disk brush and roller brush are connected to motors and a debris hopper, allowing for simultaneous operation and easy adjustment, enabling effective removal of all types of dirt without pre-sweeping and reducing component replacement needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a cleaning machine is equipped with only a roller brush, then it is simple in structure and easy to operate, but it cannot effectively remove stubborn stains from the floor
Solution Approach 1:
The patent combines a roller brush and a disc brush into a single cleaning machine, allowing the device to handle both general dust removal and stubborn stain removal. The roller brush is positioned for general cleaning while the disc brush targets stubborn stains, resolving the contradiction between structural simplicity and cleaning effectiveness.
Solution Approach 2:
The cleaning machine is designed with multi-functionality by incorporating both roller brush and disc brush mechanisms. This allows a single device to perform multiple cleaning tasks (general dust removal and stubborn stain removal) that previously required separate devices, thereby improving cleaning effectiveness without significantly complicating the overall structure.
2Reliability
If a cleaning machine is equipped with only a disc brush, then it can effectively remove stubborn stains, but it becomes tangled and damaged when encountering large numbers of stone pieces, leaves or plastic bags
Solution Approach 1:
By merging the roller brush and disc brush in one machine, the system can use the appropriate brush type for different conditions. The roller brush handles general debris while the disc brush targets stains, preventing the disc brush from being damaged by large debris and maintaining operational reliability.
Solution Approach 2:
The patent incorporates a movable brush tray that can be adjusted or removed, allowing the operator to adapt the machine's configuration based on the cleaning task. This dynamic adjustment capability prevents damage to the disc brush when encountering unsuitable debris while maintaining its effectiveness for stain removal when appropriate.
3Adaptability or versatility
If a cleaning machine supports both roller and disk brushes, then it can remove all kinds of dirt, but the replacement process is too complicated for the operator to perform alone
Solution Approach 1:
The patent divides the brush system into separate, independently replaceable modules (roller brush and disc brush) mounted on a movable brush tray. This segmentation allows each brush to be replaced individually without affecting the other components, simplifying the replacement process while maintaining cleaning versatility.
Solution Approach 2:
The movable brush tray design allows for easy adjustment and replacement of brushes. The tray can be moved to access and replace either the roller brush or disc brush independently, making the replacement process simple enough for a single operator to perform while maintaining the ability to handle all kinds of dirt.
4Productivity
If a cleaning machine integrates both roller brush and disc brush, then it enhances cleaning efficiency and reduces maintenance costs, but it increases device complexity
Solution Approach 1:
The patent merges the roller brush and disc brush systems into a single integrated cleaning machine with a shared motor, control system, and movable brush tray. This merging approach enables the device to handle all types of dirt (dust, stains, and debris) simultaneously, enhancing cleaning efficiency while managing structural complexity through shared components.

AI summary
The present invention is a cleaning appliance equipped both a roller brush and a disc brush, and belongs to the field of floor washing and cleaning equipment. It includes a control rod with a brush plate hinged below; the latter includes a base plate and a squeegee is attached below it; the working ends of both the disc brush and the roller brush are set below the brush plate. The disk brush includes a first motor fixed on the upper surface of the base plate; the roller brush includes a bearing hinge connected to the upper surface of the base plate. The invention can be applied to a variety of floors with stubborn and complex stains; its operation process is simple and does not require the user to replace any parts, thus greatly improving the efficiency; the combination of the roller brush and the disc brush allows the user to apply the product to clean complex stains directly without having to sweep the floor in advance, making the cleaning efficiency much higher.
