Low-Profile Cyclonic Dust Separator for Fine Particle Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cyclonic dust separators are often too bulky and expensive, making it difficult to place them in small workshops, and they fail to efficiently capture fine particles that pose health risks, necessitating the need for a compact, high-efficiency, low-profile dust separator that can effectively remove particulates and small debris from dust-laden air.
Innovation Solution
A cyclonic dust separator with a low-profile design utilizing centrifugal force and inertia to separate particulate matter from air, featuring a unique shape that allows for efficient removal of particles down to 1 μm in size, compatible with standard containers, and scalable for various applications, including woodshops and industrial systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cyclonic dust separators are used, then dust separation function is provided, but the device becomes bulky and expensive
Solution Approach 1:
The patent transitions from conventional three-dimensional cyclonic separators to a two-dimensional planar separator design. The separator plate with its specific geometric configuration achieves dust separation functionality in a flattened, low-profile structure that occupies minimal vertical space while maintaining effective separation performance through optimized inlet/outlet port arrangements and centrifugal force utilization.
Solution Approach 2:
The patent extracts the essential dust separation function from the bulky conventional cyclone chamber and implements it through a simplified separator plate structure. By removing unnecessary three-dimensional volumetric elements and retaining only the critical separation mechanisms (inlet ports, outlet ports, and separator plate geometry), the design achieves high dust separation efficiency with dramatically reduced size and cost.
2Reliability
If conventional cyclonic dust separators are used, then dust separation is achieved, but fine particles are not efficiently captured
Solution Approach 1:
The patent applies local quality by optimizing specific regions of the separator plate for fine particle capture. The inlet ports and outlet ports are strategically positioned and sized to create appropriate flow patterns and centrifugal forces in critical zones, enabling efficient fine particle separation without requiring complex multi-stage structures throughout the entire device.

AI summary
A cyclonic particle separator includes a first member having an arcuate outer wall and an inlet port having a diameter d1 extending from the outer wall in a first direction and an outlet port extending from the wall in a second direction, the first direction being different than the second direction; a separator plate in communication with the first member; and a cyclonic chamber defined by the separator plate and the outer wall, the cyclonic chamber, the separator plate, and the outlet port having a common central axis.
