Removable Driven Agitator Assembly for Easy Debris Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vacuum cleaners face difficulties in removing debris from mechanical agitators, such as rotating brush rolls, which can lead to decreased performance and potential damage, and these agitators are often not suitable for all surfaces, limiting the versatility of the vacuum cleaner.
Innovation Solution
A removable rotatable agitator assembly with an openable agitator chamber and a drive mechanism that allows for easy access and removal of the agitator, featuring a splined driven member for engagement with a splined drive member, enabling easy inspection, cleaning, and replacement, and allowing for interchangeable agitator elements suited for different surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rotating brush roll is used as a mechanical agitator, then agitation function is provided for carpet cleaning, but debris removal becomes difficult and performance decreases
Solution Approach 1:
The brush roll is segmented into multiple independent bristle sections that can be easily separated and removed. Each section can be independently accessed and cleaned, allowing debris to be removed without disassembling the entire agitator assembly or inverting the cleaning head.
Solution Approach 2:
The bristle sections are extracted as removable components from the brush roll assembly. This allows users to pull out and clean individual sections that contain debris, eliminating the need to invert the entire cleaning head or disassemble complex mechanisms.
2Device complexity
If the agitator is located inside the surface cleaning head, then the structure is compact, but debris removal requires inverting the head and is difficult
Solution Approach 1:
The compact internal structure is maintained while the bristle sections are segmented for easy removal. Users can access and remove debris-loaded bristle sections through the existing opening without inverting the head, combining structural compactness with ease of maintenance.
Solution Approach 2:
The bristle sections are extracted as removable components that can be pulled through the opening in the cleaning head housing. This allows debris removal without inverting the head or disassembling the compact structure, maintaining both compactness and ease of maintenance.

AI summary
A removable rotatable driven agitator is used in a surface cleaning head and is driven by a drive mechanism that axially engages a driven end of the agitator. The removable rotatable driven agitator may be located in an openable agitator chamber for purposes of removing debris and/or removing the agitator. The openable agitator chamber may be covered by an external cover that is movable between an open position and a closed position. The removable agitator may be secured in the agitator chamber by the external cover. The removable rotatable agitator may have an end cap mounted on a rotatable bushing at a non-driven end and may have a splined driven member at the driven end to engage a splined drive member on the drive mechanism.
