Floor Brush Assembly with Bump Channels to Prevent Dirt Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor scrubbers face challenges with inconvenient use and unsatisfactory cleaning performance, particularly in effectively clearing dirt and water stains without leaving behind a line of dirt or requiring frequent lifting of the brush assembly.
Innovation Solution
A floor brush assembly with a second scraping piece featuring bumps that form a channel to direct dirt to the suction inlet, allowing the roller brush to abut the surface while the bumps on the scraping piece switch positions to ensure dirt is collected, and a first scraping piece that scrapes and directs water stains into the suction inlet, enhancing cleaning efficiency and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the floor brush assembly moves forward with the roller brush abutting the surface, then cleaning coverage is improved, but dirt accumulates in front of the brush forming a line of dirt
Solution Approach 1:
The scraping piece is segmented with multiple bumps distributed along its length, creating multiple channels that divide and direct dirt flow. This segmentation prevents dirt accumulation by distributing the dirt redirection function across multiple points, allowing dirt to be continuously channeled to the suction inlet without forming a continuous line of dirt.
Solution Approach 2:
The bumps on the scraping piece act as intermediaries between the roller brush and the suction inlet. These bumps create channels that mediate the transport of dirt from the cleaning surface to the suction inlet, facilitating efficient dirt removal while the roller brush maintains continuous contact with the surface for thorough cleaning.
2Object-generated harmful factors
If the scraping bar is lifted to clear rubbish, then dirt removal is improved, but operation convenience deteriorates
Solution Approach 1:
The scraping piece with bumps automatically performs the dirt redirection function during normal forward movement without requiring user intervention. The bumps self-adjust to create channels as dirt encounters them, and the vacuum suction naturally draws dirt through these channels, eliminating the need for manual lifting or adjustment of the brush assembly.
Solution Approach 2:
The bumps are pre-positioned on the scraping piece to proactively create channels before dirt accumulation becomes problematic. This preliminary structural arrangement ensures that dirt is continuously directed toward the suction inlet throughout the cleaning process, preventing line of dirt formation before it occurs.
3Productivity
If the roller brush rotates to clean the floor, then cleaning effectiveness is improved, but water stains and dirt are left behind
Solution Approach 1:
The bumps on the scraping piece serve as intermediaries that bridge the gap between the roller brush cleaning action and the vacuum suction. They create controlled channels that efficiently transport water stains and fine dirt particles from the cleaned surface directly to the suction inlet, ensuring complete removal rather than leaving residues behind.

AI summary
A floor brush assembly and cleaning equipment with the floor brush assembly for cleaning surfaces to be cleaned. The forward direction of the floor brush assembly is the front and the opposite direction is the back. The floor brush assembly comprises a floor brush base, a roller brush with a roller being arranged on the floor brush base, and a second scraping piece which is arranged on the bottom of the floor brush base and in front of the roller brush and is provided with at least two second bumps distributed at intervals along its length direction. At least the roller brush abuts on the surface to be cleaned when the roller brush abuts on the surface to be cleaned, with a second channel for dirt passing through being formed between the adjacent second bumps to make dirt reach the suction inlet of the floor brush base.
