Bagless Vacuum Dust Bin Emptying With Guided Coarse Separator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Emptying the dust collection device of bagless vacuum cleaners with a central filter system is not optimally solved, leading to uncontrolled dust dispersion, discomfort, and unhygienic conditions, as well as complex handling of the coarse dirt separator collar, which results in reduced suction power and unhygienic conditions due to infrequent cleaning.
Innovation Solution
A vacuum cleaner design featuring a dust collection container with a pivotable bottom flap and a vertically movable coarse dirt separator on a guide, allowing for controlled access and easy emptying by pressing an external opening button, eliminating the need for manual handling of dirt-laden parts and simplifying the cleaning process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cover is removed from the dust collection container to empty it, then the dust collection container can be emptied, but dust falls down in an uncontrolled manner causing discomfort and unhygienic conditions
Solution Approach 1:
The dust collection device is segmented into multiple functional components: a dust collection container, a separately removable coarse dirt separator, and a bottom flap system. This segmentation allows the coarse dirt separator to be removed independently through the bottom flap opening, enabling controlled emptying of different dirt types through separate access points rather than removing the entire cover.
Solution Approach 2:
The coarse dirt separator is extracted as a separate removable component from the dust collection container. It can be removed through the bottom flap opening without removing the main cover, allowing dirt to be discharged in a controlled manner through the bottom flap area rather than uncontrolled dispersion when the cover is removed.
2Ease of repair
If the circumferential coarse dirt separator collar is removed separately by hand, then it can be cleaned, but dust falls down from the collar in an uncontrolled manner causing discomfort and unhygienic conditions
Solution Approach 1:
The coarse dirt separator including the collar is extracted as a separate removable component that can be taken out through the bottom flap opening. This allows the collar to be removed and cleaned without manually handling it inside the container, and dirt falls in a controlled manner through the bottom flap area rather than uncontrolled dispersion.
Solution Approach 2:
The bottom flap opening serves as an intermediary access point for removing the coarse dirt separator collar. Instead of directly reaching into the container to remove the collar, the user opens the bottom flap and uses this intermediate opening to extract the collar, which controls the path of falling dirt and reduces uncontrolled dispersion.
3Productivity
If the bottom of the dust collection container is opened to dispose of fine dust, then fine dust can be emptied, but dirt separated by the coarse dirt separator collar remains above the collar
Solution Approach 1:
The emptying process is segmented into two independent operations: fine dust is emptied through the bottom flap opening, and coarse dirt is removed by extracting the coarse dirt separator through the same opening. This segmentation allows both types of dirt to be emptied without requiring separate access points or complex handling procedures.
Solution Approach 2:
The bottom flap opening is designed as a multi-functional access point that serves both for disposing fine dust and for removing the coarse dirt separator. This universal opening eliminates the need for separate access points, simplifying the overall handling procedure while maintaining efficient emptying of both dirt types.
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
Enables simple and hygienic emptying of the dust collection container with minimal user intervention, reducing dust dispersion and promoting regular cleaning, thus maintaining suction power and ensuring cleanliness.
Implementation Method 1
the coarse dirt separator, which is vertically movable on its guide, moves downwards and slides out of the interior of the dust collection container

AI summary
The vacuum cleaner has a dust collecting device (10), which has a dust collection container (12) and a cover (14) that closes at first side of the dust collection container. A bottom flap (16) is provided, which is closed at second side of the dust collection container and is pivotable to open the dust collection container. A coarse sediment bowl (22) is located inside the dust collection container and is vertically movable on a guide. An independent claim is included for a method for using a vacuum cleaner.
