Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners with multi-cyclone structures face issues such as increased height, reduced dust collection volume, inefficient air introduction between cyclones, and poor separation of fine dust due to interference and decreased suction power, as well as inconvenient dust discharge processes.
Innovation Solution
A dust collector design that accommodates a second cyclone within a first cyclone, utilizing first and second guide vanes to enhance rotational flow and air introduction, and a mesh filter for separate dust and fine dust collection, with a lower cover for simultaneous discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a multi-cyclone structure with vertically disposed cyclones is used, then fine dust separation performance is improved, but the height of the dust collector increases
Solution Approach 1:
The patent applies nesting by placing the second cyclone inside the first cyclone, with the second cyclone positioned in the central region of the first cyclone. This nested configuration allows multiple cyclones to occupy the same vertical space, reducing the overall height of the dust collector while maintaining the fine dust separation capability provided by the multi-cyclone structure.
Solution Approach 2:
The patent transitions from a vertical stacking arrangement to a radial/concentric arrangement by positioning cyclones at different radial distances from the central axis. The first cyclone is disposed at a first radial distance and the second cyclone at a second radial distance, utilizing the radial dimension to accommodate multiple cyclones without increasing height.
2Length of stationary object
If the dust collector is designed with a slim profile to reduce height, then the height is reduced, but the volume for collecting dust decreases
Solution Approach 1:
By nesting the second cyclone inside the first cyclone, the patent maximizes the utilization of the available internal volume without increasing the external dimensions. The dust collection chambers of both cyclones are arranged concentrically, allowing both to contribute to dust collection within the same vertical envelope, thereby maintaining collection volume while reducing height.
Solution Approach 2:
The patent segments the dust collection function into multiple cyclones operating at different radial positions. Each cyclone has its own dust collection chamber, and the segmented arrangement allows efficient use of space, maintaining total collection volume while compacting the vertical profile.
3Quantity of substance
If air passes through the first cyclone before entering the second cyclone, then large dust is removed, but the flow speed decreases and fine dust separation efficiency is reduced
Solution Approach 1:
The patent applies local quality by providing different functional characteristics to different regions of the cyclone system. The first cyclone handles large dust particles with its larger separation capacity, while the second cyclone positioned at a different radial distance handles fine dust particles. The guide passages are specifically designed to maintain appropriate flow speeds in each region, with the second guide passage optimized for fine dust separation despite the reduced flow speed after the first cyclone.
4Measurement precision
If a tangential inhalation type cyclone structure is used, then dust separation is achieved, but guide passages are required which increase complexity and passage loss
Solution Approach 1:
The patent merges the functions of the cyclone body and the guide passages by forming the guide passages as integral parts of the cyclone structure. The first guide passage is formed in the first cyclone and the second guide passage is formed in the second cyclone, eliminating the need for separate, complex guide passage components and reducing passage loss through streamlined design.
