Segmented Cleaning Strip for Universal Carpet and Floor Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners require multiple roller brushes with different materials for cleaning carpets and floors, leading to inconvenience, increased consumption, and potential damage to carpets due to limited elasticity and inability to effectively clean hair from carpets.
Innovation Solution
A flexible cleaning strip with protrusions and notches on a roller brush body, allowing it to clean both carpets and floors without damaging them, by extending into carpets to remove hair and dirt.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a whole strap is mounted on the roller brush for floor cleaning, then the cleaning area is increased, but the elasticity is limited and hair cannot be dug out from carpet gaps
Solution Approach 1:
The cleaning strip is segmented into multiple cleaning protrusions separated by notches. Each cleaning protrusion can independently penetrate into carpet gaps to dig out hair, while the notches provide flexibility and prevent the strip from acting as a rigid whole that cannot adapt to carpet surfaces.
Solution Approach 2:
Different regions of the cleaning strip have different structures: the cleaning protrusions have concentrated cleaning force for penetrating carpet gaps, while the notched regions provide flexibility and adaptability. This local differentiation allows the strip to effectively clean both carpet and floor surfaces.
2Adaptability or versatility
If an flocked roller brush is used for carpet cleaning, then carpet cleaning effectiveness is improved, but it may damage smooth finish of floors
Solution Approach 1:
The cleaning strip with protrusions and notches achieves multi-functionality, effectively cleaning both carpet surfaces (by penetrating gaps) and floor surfaces (by maintaining flexibility and avoiding excessive pressure). This eliminates the need for separate roller brushes for different surfaces.
3Adaptability or versatility
If multiple roller brushes with different materials are purchased for different surfaces, then cleaning effectiveness for each surface is improved, but convenience is reduced and consumption cost increases
Solution Approach 1:
A single cleaning strip design with protrusions and notches achieves universal applicability for both carpet and floor cleaning, eliminating the need to purchase and manage multiple specialized roller brushes. The strip maintains effectiveness across different surfaces while simplifying user operation.
4Area of stationary object
If a wide strap structure is used, then broader planar regions can be cleaned, but the strap cannot extend into carpet for effective cleaning
Solution Approach 1:
The wide strap is segmented into multiple cleaning protrusions with notches between them. This segmentation allows the strip to maintain broad coverage while enabling individual protrusions to penetrate into carpet gaps, combining the advantages of wide coverage and deep penetration.
Solution Approach 2:
The cleaning strip transitions from a flat two-dimensional strap to a three-dimensional structure with protrusions having height and depth. This dimensional change enables the strip to penetrate vertically into carpet gaps while maintaining horizontal coverage, effectively addressing both planar cleaning and deep penetration requirements.
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 flexible cleaning strip enables universal cleaning of various surfaces with reduced machining costs, effectively removing hair and dirt from carpets and floors without intertangling or deforming the carpet.
Implementation Method 1
the cleaning strip is a flexible cleaning strip and further includes at least one cleaning protrusion connected with the mounting region
Implementation Method 2
the cleaning protrusions can extend into the carpet to fully dig up hair, dirt and the like in the carpet

AI summary
The present disclosure discloses a cleaning strip, a roller brush body and a vacuum cleaner. The roller brush body of the present application can be used for cleaning a carpet and the like, cleaning protrusions can extend into the carpet to fully dig up hair in the carpet, meanwhile, each notch is formed between every two cleaning protrusions, the cleaning protrusions have certain flexibility, and thus the carpet can be prevented from being damaged and deformed due to pressing during a cleaning process. In the present application, only a cleaning element needs to be arranged on the roller brush body, is capable of extending into the carpet for cleaning, a user does not need to replace different roller brushes according to different ground surfaces, and machining cost of a roller brush is lower.
