Floor brush structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional floor brushes face challenges in simultaneously addressing hair tangling issues and maintaining effective cleaning performance, especially when cleaning carpets and floors with different bristle types.
Innovation Solution
A floor brush structure featuring a housing with a rolling brush that includes both hard and soft bristles, along with comb teeth, is designed. The hard bristles are shorter than the soft bristles, and the comb teeth are positioned to effectively untangle hairs, optimizing the height difference and insertion depth for efficient cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If hard bristles are used on the rolling brush, then carpet cleaning effect is improved, but hair tangling problem worsens
Solution Approach 1:
The rolling brush is segmented into two distinct bristle layers: a first bristle layer with hard bristles for carpet cleaning, and a second bristle layer with soft bristles for floor cleaning. This segmentation allows each layer to perform its specialized function without the hard bristles causing excessive hair tangling on smooth floors.
Solution Approach 2:
Different regions of the rolling brush are assigned different bristle properties. The first bristle layer uses hard bristles specifically positioned for carpet cleaning areas, while the second bristle layer uses soft bristles for floor areas. This local quality differentiation optimizes cleaning performance for each surface type while minimizing hair tangling on floors.
2Object-generated harmful factors
If soft bristles are used on the rolling brush, then hair tangling problem is reduced, but carpet cleaning effect worsens
Solution Approach 1:
The rolling brush is divided into functional zones with the first bristle layer containing hard bristles specifically for carpet cleaning tasks, while the second bristle layer with soft bristles handles floor cleaning. This ensures carpets receive adequate mechanical action from hard bristles while floors are cleaned by soft bristles that minimize hair tangling.
Solution Approach 2:
The brush head incorporates spatially varying bristle characteristics where hard bristles are positioned to contact carpet surfaces and soft bristles contact floor surfaces. This local quality assignment allows the system to achieve both effective carpet cleaning and reduced hair tangling on floors simultaneously.
3Productivity
If hard bristles directly contact the floor, then cleaning effect is improved, but floor damage risk increases
Solution Approach 1:
The second bristle layer uses soft bristles specifically for floor contact areas to provide gentle cleaning without damaging floor surfaces. The hard bristles in the first layer are positioned to primarily contact carpets, reducing their direct contact with delicate floor surfaces while maintaining effective carpet cleaning capability.

AI summary
The present disclosure discloses a floor brush structure. A rolling brush includes a rolling body, hard bristles and soft bristles, the rolling body is rotatably disposed in a housing, a plurality of hard bristles are disposed on an outer surface of the rolling body, a plurality of soft bristles are disposed on the outer surface of the rolling body, a height of the hard bristles is lower than a height of the soft bristles, and a height difference range of the hard bristles and the soft bristles is 0.2 mm to 5 mm. Comb teeth are disposed in the housing and correspond to the rolling brush, when the rolling brush rotates, tooth tips of the comb teeth are able to be inserted into the hard bristles and/or the soft bristles to comb hairs tangled on the rolling brush, and a depth range is 0.1 mm to 5 mm. In this solution, by installing the hard bristles and the soft bristles on the rolling body, when hairs on a floor are cleaned away, direct contact between the hairs and the hard bristles is reduced, at the same time, the hairs tangled on the rolling brush are combed by cooperating with the comb teeth, and installation parameters and structures of the bristles and the comb teeth are matched at high precision during installation, so that a floor brush achieves an efficient cleaning function.
