Vacuum Brush Bristle Layout for Low-Dispersion Dust Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dust removal methods often require separate steps to sweep and collect dust, leading to inefficient dust dispersion into the air and potential health hazards, especially for individuals with asthma or allergies.
Innovation Solution
A cleaning brush apparatus with rows of bristles and suction holes that can be attached to a vacuum, allowing dust to be trapped between bristles and collected without airborne dispersion, featuring protective bristles to prevent surface damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional sweeping methods are used to remove dust, then dust can be collected, but dust particles frequently become airborne and disperse into the air during the process
Solution Approach 1:
The patent combines the dust stirring function (bristles) and dust collection function (suction) into a single integrated device. The bristles agitate dust particles while the suction holes simultaneously capture them, preventing airborne dispersion while maintaining efficient collection.
Solution Approach 2:
The suction holes are positioned to capture dust particles at the moment they are stirred up by the bristles, before they can become airborne and disperse. This preliminary capture action prevents the harmful effect of airborne dust while the stirring action continues to be effective.
2Device complexity
If separate sweeping and collecting steps are used, then dust can be removed, but the process requires additional cleaning steps and devices
Solution Approach 1:
The patent merges two separate functions (sweeping/stirring and collecting) into one integrated device. The bristle assembly stirs dust while the attached suction system collects it simultaneously, eliminating the need for separate sweeping and collecting operations.
Solution Approach 2:
The cleaning device performs multiple functions: the bristles stir and agitate dust particles, the suction holes capture and collect dust, and the overall structure serves as both a stirring tool and a collection device, reducing the need for multiple specialized tools.
3Ease of operation
If bristles are used to sweep dust, then dust can be moved, but protective surfaces may be damaged or scratched
Solution Approach 1:
The patent uses bristles of varying lengths and materials in different zones of the brush head. Softer, shorter bristles contact the surface for gentle dust agitation, while harder, longer bristles reach into crevices for effective dust stirring, providing both surface protection and cleaning effectiveness.
Solution Approach 2:
The brush assembly combines different materials with complementary properties: soft bristles for surface contact and protection, harder bristles for effective dust stirring, and suction components for dust capture. This composite structure achieves both ease of operation and surface protection.
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
Effectively collects dust in a central location while minimizing airborne dispersion, enhancing safety and efficiency in dust removal.
Implementation Method 1
To account for the venturi effect, the suction holes closer to the first end of the handle are smaller than those at the second end

AI summary
A brush for dusting and cleaning includes a handle having a first end and a second end, an outer rail of bristles along an outer portion of the brush having a first row of outer bristles and a second row of outer bristles; an inner rail of bristles along an inner portion of the brush having a first row of inner bristles and a second row of inner bristles; at least one row of suction holes located between the first row of outer bristles and the second row of outer bristles to remove materials trapped within the brush; and a front row of bristles located along the second end of the handle.
