Solution Overview
Problem
Cyclonic vacuum cleaners face challenges in achieving high separation performance without compromising suction power, as particles can be re-entrained due to turbulence and small air movements, and maintaining cleanliness while optimizing water usage for effective filtration.
Innovation Solution
A bagless vacuum cleaner design featuring a cyclone tube with a mushroom-shaped bucket containing liquid, where the bucket's diameter is at least twice that of the cyclone, and a rim to regulate water entry, preventing water from entering the cyclone during startup and minimizing contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a cyclone tube is used for particle separation, then separation performance is improved, but particles can be re-entrained due to turbulence and small air movements
Solution Approach 1:
A liquid pool is introduced as an intermediary substance between the cyclone tube and the collection container. The liquid pool captures particles that would otherwise be re-entrained by turbulence, allowing them to settle before entering the collection space. This mediator prevents re-entrainment while maintaining separation performance.
Solution Approach 2:
The invention changes the physical state and flow characteristics by introducing a liquid phase. The liquid pool creates a damping effect on air movements and turbulence, altering the flow parameters to prevent particle re-entrainment while maintaining effective separation.
2Measurement precision
If water is used for filtration, then filtration effectiveness is improved, but water contamination and cleanliness maintenance become problematic
Solution Approach 1:
The liquid pool serves as an intermediary filtration stage that captures particles before they can contaminate the main collection space. By having particles settle in the liquid pool first, the amount of contamination reaching the collection container is significantly reduced, maintaining cleanliness while preserving filtration effectiveness.
Solution Approach 2:
The system allows liquid to be discarded and replaced periodically. The liquid pool accumulates contaminants over time, and when saturated, the liquid can be emptied and replaced with fresh liquid, restoring filtration effectiveness without permanent contamination of the collection space.
3Stability of the object's composition
If the bucket diameter is increased to prevent particle re-entrainment, then separation stability is improved, but device size and complexity increase
Solution Approach 1:
The liquid pool is nested within the existing vacuum cleaner structure, utilizing the space between the cyclone tube and the collection container. This nested arrangement provides the stability benefits of a larger diameter without significantly increasing the overall device size, as the liquid pool occupies otherwise unused space.
Solution Approach 2:
Instead of increasing the horizontal diameter of the collection container, the invention utilizes the vertical dimension by creating a liquid pool at the bottom of the cyclone tube. This dimensional shift achieves separation stability without proportionally increasing overall device complexity and size.
