Vacuum Suction Tool Brush Cleaner for Hygienic Dust Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners with rotating brushes face issues in safely and hygienically removing entangled dust, as previous solutions either spread dust or require high pull-out forces, and may not effectively prevent dust from escaping during the removal process.
Innovation Solution
A suction tool design featuring a rotating brush with a dust removing mechanism that includes a first remover guided axially within a gap and a second remover that contacts the brush tip, allowing for efficient and sanitary removal of dust without spreading it, and reducing the pull-out force required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the rotating brush is removed to remove dust, then dust can be removed, but dust may be spread or directly touched by hand which is not sanitary, and the cutter blade may be touched which is not safe
Solution Approach 1:
The dust removing means acts as an intermediary tool between the user's hand and the dust/cutter blade. It includes a holder with a dust removing portion that contacts the rotating brush to remove dust, allowing dust removal without direct hand contact with dust or the cutter blade, thus solving the sanitation and safety issues.
2Ease of operation
If the dust removing means is brush bristles, then dust can be removed, but the bristles bend in pull-out direction which causes dust to flow out and increases pull-out force
Solution Approach 1:
The dust removing portion is designed with specific physical parameters: it has a predetermined shape that fits within gaps of the rotating brush, and its material hardness is controlled to be harder than the rotating brush material. This allows effective dust removal without bending, reducing pull-out force and preventing dust escape.
3Productivity
If the cutter blade is used to remove thread-like dust, then dust can be removed, but the cutter blade may be touched which is not safe
Solution Approach 1:
The dust removing means serves as a safe intermediary that performs the dust removal function without exposing the user to the cutter blade. The holder structure allows the dust removing portion to contact the rotating brush while keeping the cutter blade retracted or protected, eliminating direct user contact with the sharp blade.
4Ease of operation
If the rotating brush is pulled out for dust removal, then dust can be removed, but the rotating brush is pulled in an unstable manner which increases pull-out force
Solution Approach 1:
The dust removing means is designed to work with the rotating brush in its installed position, utilizing the brush's own structure (gaps between cleaning bodies) to guide and stabilize the removal process. The predetermined shape of the dust removing portion fits within these gaps, providing stability and reducing the force needed for operation.
