Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld vacuum cleaners with single cyclones and filter or bag systems require frequent maintenance and suffer from reduced suction power over time, limiting their performance and pick-up capability.
Innovation Solution
A handheld cleaning appliance featuring a cyclonic separator with multiple second cyclones arranged in parallel, eliminating the need for barrier means like filters and allowing for sustained high suction power and reduced maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single cyclone followed by a filter or bag is used, then the device can separate dirt and dust, but the filter requires frequent maintenance and performance decreases over time
Solution Approach 1:
The cyclonic separator is divided into multiple parallel cyclones (typically 3-5) instead of using a single cyclone followed by a filter. Each cyclone independently separates particles, and the combined effect provides sustained separation performance without filter clogging or maintenance requirements.
2Reliability
If a cyclonic separator with multiple second cyclones in parallel is used, then fine dirt and dust can be separated without filters, but the space occupied becomes bulky and heavy
Solution Approach 1:
The multiple second cyclones are arranged concentrically around the first cyclone, with each subsequent cyclone nested within the envelope of the previous one. This nested configuration minimizes the overall volume and weight while maintaining the separation effectiveness of multiple parallel cyclones.
3Reliability
If a cyclonic separator with multiple second cyclones in parallel is used, then fine dirt and dust can be separated without filters, but the space occupied becomes bulky and heavy
Solution Approach 1:
The multiple second cyclones are arranged concentrically around the first cyclone, with each subsequent cyclone nested within the envelope of the previous one. This nested configuration minimizes the overall volume and weight while maintaining the separation effectiveness of multiple parallel cyclones.
4Power
If barrier-type filter means are used, then dirt and dust can be separated, but suction power and pick-up capability reduce over time
Solution Approach 1:
The filter or bag (barrier means) is completely removed from the system. Instead, multiple parallel cyclones are used to separate fine particles through centrifugal force alone, eliminating the component that causes suction power degradation over time.

AI summary
A handheld cleaning appliance includes a dirty air inlet, a clean air outlet and separating apparatus for separating dirt and dust from an airflow in an airflow path leading from the air inlet to the air outlet. The separating apparatus includes a cyclonic separator having at least one first cyclone and a plurality of second cyclones arranged in parallel with one another and located downstream of the first cyclone. By providing a cyclonic separator having a plurality of second cyclones in parallel, the handheld cleaning appliance is capable of separating fine dirt and dust particles without using barriers such as filters or bags which need maintenance to ensure that performance remains high over a period of time.
