Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaning devices with external separating devices suffer from rapid clogging and reduced service life due to dust accumulation, leading to cumbersome attachment and increased size, which compromises their functionality and ease of use.
Innovation Solution
A compact separating device integrated with the vacuum cleaning device, featuring a cyclone separator with axial design and accumulators for continuous dirt particle discharge, preventing clogging and extending service life, and allowing modular retrofitting into existing systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If a separator is used to remove dirt particles from intake air, then the filter's lifespan is extended, but the separator becomes completely filled with dust and dirt particles after only a relatively short time
Solution Approach 1:
The separator is divided into multiple separation chambers (first and second chambers) that can be independently filled and emptied. This segmentation allows one chamber to be in use while another is being emptied or is available as backup, preventing the entire separator from becoming full and non-functional after a short time.
Solution Approach 2:
The system automatically discards accumulated dirt particles from one separation chamber while continuing to operate with other chambers. The emptied chamber can then be reused, effectively recovering the separator's capacity and maintaining continuous operation without complete filler clogging.
2Reliability
If a separator is attached to the outside of the vacuum cleaner as a separate component, then the filter is protected from dust, but the vacuum cleaner becomes larger and more difficult to handle
Solution Approach 1:
The separator is merged with the vacuum cleaner's existing collection container, forming an integrated system. The separation chambers are positioned within or alongside the collection container, eliminating the need for a separate external separator attachment. This combining approach maintains filter protection functionality while reducing overall device size and improving handling.
3Duration of action of stationary object
If multiple separation chambers are used to extend service life, then the separator can be continuously emptied, but the device complexity increases
Solution Approach 1:
Multiple separation chambers share common structural elements and operational mechanisms. The chambers can be configured in series or parallel, allowing the system to handle varying dust loads while maintaining a relatively simple overall structure. The multi-chamber design provides extended service life without proportionally increasing complexity through standardized, interchangeable components.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents clogging, extends the service life of the separating device, and enhances usability by maintaining a clear airflow path while being compact and easily integratable with existing vacuum cleaning devices.
Implementation Method 1
the cyclone separator is designed in the form of an axial separator with a first and a second tube
Implementation Method 2
a significant portion of the particles are removed from the air before it passes through the filter

AI summary
The invention relates to a separating device (2), which can be connected to a vacuuming device (1) in order to separate dirt particles from an air flow (LS) suctioned by the vacuuming device (1), said separating device containing at least one separator (21, 22). The at least one separator (21, 22) contains an inlet opening (23) for the air flow (LS) and a first and a second outlet opening (21c, 22c), the first outlet opening (21c, 22c) being used for the exit of suctioned dirt particles from the separator (21, 22) and the second outlet opening (21d, 22d) being used for the exit of the suctioned air flow (LS) and the suctioned dirt particles from the separator (21, 22), and a first and a second collecting store (12, 13, 14, 15) for collecting the dirt particles separated from the separator (21, 22) being contained, and the first collecting store (12, 14) being positioned below the first outlet opening (21c, 22c) in a direction (B) and the second collecting store (13, 15) being positioned below the second outlet opening (21d, 22d) in a direction (B).
