Vacuum Brush-Roll Cleaning Element for Hair Entanglement Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Elongate items such as threads, wool fibers, and hairs tend to entangle with the brush-heads of vacuum cleaners, impairing their functioning and cleaning efficiency.
Innovation Solution
A cleaning arrangement with a moveable cleaning element that selectively engages and disengages with the rotatable brush-roll, using a cleaning edge to loosen and remove entangled debris, and can be manually or automatically moved along a guiding shaft to avoid damaging the bristles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a cleaning element continuously engages with the rotatable cleaning member to remove entangled debris, then cleaning effectiveness is improved, but bristle wear increases
Solution Approach 1:
The cleaning element is designed to repeatedly engage and disengage from the rotatable cleaning member in periodic cycles. During engagement phases, the cleaning element removes entangled debris; during disengagement phases, the bristles are relieved from contact stress. This periodic action pattern allows effective debris removal while preventing continuous wear that would occur with constant engagement.
Solution Approach 2:
The cleaning element is made moveable between engaged and disengaged configurations, transforming a static cleaning system into a dynamic one. This movability allows the cleaning element to adapt its position based on operational needs, engaging when debris removal is required and disengaging to protect bristles, thereby optimizing both cleaning effectiveness and component longevity.
2Duration of action of moving object
If the cleaning element selectively engages only in bristle-free sections, then bristle wear is reduced, but cleaning coverage is limited
Solution Approach 1:
The cleaning element's movability along the rotatable cleaning member enables it to dynamically access different sections, including bristle-free areas. By moving to and from these sections, the system can perform cleaning actions on the drum surface without continuously contacting the bristles, thus protecting them while still achieving meaningful cleaning coverage.
Solution Approach 2:
The bristle-free sections of the rotatable cleaning member serve as intermediary zones where the cleaning element can perform maintenance functions. These sections act as intermediate work areas that allow the cleaning element to operate without directly impacting the bristles, enabling a form of indirect cleaning that protects the primary cleaning components while still maintaining overall system hygiene.
