Floor Cleaner Edge Brush Design for Corner Debris Pick-Up
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor cleaners struggle to efficiently pick up debris from the edges and corners of surfaces, leaving behind dirt and dust.
Innovation Solution
The floor cleaner design incorporates a brushroll chamber with a suction inlet and an edge brush mounted on a mounting plate, which directs debris from the lateral sides towards the suction inlet, ensuring effective pick-up.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional brushroll and suction inlet configuration is used, then the device structure is simple, but debris from edges and corners cannot be effectively picked up
Solution Approach 1:
The cleaning device is segmented into distinct functional zones: a central brushroll chamber for general surface cleaning and lateral edge brush assemblies for edge and corner cleaning. This segmentation allows each component to specialize in specific cleaning tasks, improving overall productivity at edges and corners without requiring a complete redesign of the entire device structure.
Solution Approach 2:
The invention extends the cleaning function from the central horizontal plane to the lateral edges by adding edge brushes that operate in a different spatial dimension. The edge brushes are positioned at the lateral edges and angled to direct debris toward the suction inlet, effectively utilizing the lateral dimension to capture debris that would otherwise escape traditional central suction systems.
2Productivity
If the suction inlet is positioned only in the center, then the device structure is simple, but debris from lateral edges cannot be directed into the suction path
Solution Approach 1:
The edge brushes act as intermediary elements between the lateral edges and the central suction inlet. These brushes are mounted on lateral extensions and angled to sweep debris from the edges toward the center, effectively mediating the transfer of debris from areas that would otherwise be inaccessible to the suction path.
Solution Approach 2:
The edge brushes perform preliminary action by pre-sweeping and directing debris toward the suction inlet before the main suction force acts on it. This preliminary directional guidance ensures that debris from lateral edges is already positioned within the suction path, improving pick-up capability without requiring the suction inlet itself to be repositioned.
3Area of stationary object
If edge cleaning is added to the traditional design, then cleaning coverage is improved, but the device structure becomes more complex
Solution Approach 1:
The edge brush assemblies are designed to perform multiple functions: they clean lateral edges and corners, direct debris toward the suction inlet, and can be integrated with the existing housing structure. This multi-functionality increases cleaning coverage area while minimizing the addition of separate dedicated components for each function.
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
This configuration enhances the cleaning efficiency by guiding debris towards the suction inlet, facilitating the pick-up of dirt and dust from hard-to-reach areas like edges and corners.
Implementation Method 1
a suction source and a distribution nozzle configured to dispense a fluid onto a surface to be cleaned... A suction inlet is formed between the brushroll and the rear edge. The floor cleaner further includes a recovery tank in fluid communication with the suction source and the suction inlet. The recovery tank is configured to contain the fluid drawn by the suction source through the suction inlet from the surface to be cleaned
