Alternating Bristle and Rubber Roller Brush for Carpet Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices with roller brushes struggle to thoroughly clean tufted wool carpets as hair and debris get caught in the carpet tufts, leading to incomplete cleaning due to the brush's inability to extend deep enough into the carpet tufts.
Innovation Solution
A roller brush design featuring alternating bristle and rubber strips, with bristle strips higher than rubber strips, enhances cleaning by extending deep into the carpet, supported by a bristle layer with greater hardness to reduce hair entanglement, and a tapered structure at the driving end facilitates hair collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the roller brush uses only rubber strips for cleaning, then the brush can sweep the surface and support separated hair, but the cleaning effect on deep carpet tufts is insufficient
Solution Approach 1:
The patent combines rubber strips and bristle strips into a single brush assembly, where rubber strips provide surface sweeping and hair support, while bristle strips penetrate deep into carpet tufts. This merging of different cleaning mechanisms resolves the contradiction between surface sweeping capability and cleaning depth.
Solution Approach 2:
Different parts of the brush have different properties: rubber strips are positioned for surface contact and hair support, while taller bristle strips are positioned to reach deep into carpet tufts. This local differentiation of cleaning properties allows the brush to simultaneously address both surface and deep cleaning needs.
2Manufacturing precision
If the roller brush uses only bristle strips for cleaning, then the brush can extend deep into carpet tufts, but hair entanglement increases
Solution Approach 1:
The patent merges rubber strips with bristle strips in alternating arrangement, where rubber strips continuously sweep the surface and support separated hair, preventing it from becoming entangled in the bristle strips. This combination maintains deep cleaning capability while reducing hair entanglement.
Solution Approach 2:
The patent converts the potential harm of hair entanglement in bristle strips into a benefit by using rubber strips to sweep and support hair, guiding it away from the bristle strips. The harm of hair getting caught is transformed into an organized flow of hair along the rubber strips to the collection end.
3Ease of manufacture
If uniform bristle density is used throughout the brush, then manufacturing is simplified, but hair entanglement cannot be effectively reduced
Solution Approach 1:
The patent applies different bristle densities in different regions: the first bristle layer has lower density to reduce hair entanglement, while the second bristle layer has higher density for effective cleaning. This local differentiation resolves the contradiction between manufacturing simplicity and hair entanglement reduction.
Solution Approach 2:
The bristle strips are segmented into two distinct layers with different densities and functions. The first layer focuses on hair entanglement reduction, while the second layer focuses on cleaning effectiveness, allowing each segment to optimize its specific function.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design achieves thorough cleaning by reducing hair entanglement and facilitating centralized hair collection, ensuring effective removal of debris and hair from carpets.
Implementation Method 1
the roller brush rolls such that the rubber strips and the bristle strips alternately come into contact with the surface to be cleaned during cleaning
Implementation Method 2
the rubber strips can sweep the surface to be cleaned and support the separated hair to reduce hair entanglement

AI summary
A roller brush (10) and a cleaning device (100). The roller brush (10) comprises a roller body (11) and a plurality of brush strip groups (12). The plurality of brush strip groups (12) are arranged at intervals around the roller body (11), and each brush strip group (11) includes at least one bristle strip (121) and at least one flexible rubber strip (122); in each brush strip group (12), the rubber strip (122) and the bristle strip (121) are alternately arranged side by side, curvedly extending along an axis of the roller body (11). By providing both the rubber strip (122) and the bristle strip (121) to form the brush strip group (12), hair entanglement can be reduced while the cleaning effect is enhanced.
