Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cyclone dust collectors in vacuum cleaning devices face issues with reduced inhalation force due to clogged air holes in the grill part, requiring manual cleaning which is inconvenient and inefficient.
Innovation Solution
A cyclone dust collector design featuring a rotatable grill mounted on a fan, with a second fan generating an opposing air current to prevent dust from entering gaps and a fine filter for additional purification, ensuring easy maintenance and sustained suction power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a grill part with air through holes is disposed in the outlet part, then dust of predetermined size cannot escape from the outlet part, but dust accumulates on the outer circumferential surface of the grill part causing air holes to clog and inhalation force to lower
Solution Approach 1:
The patent applies the dynamics principle by making the grill part rotatable instead of stationary. The grill part rotates in response to air flow, creating dynamic motion that prevents dust accumulation on its outer circumferential surface. This rotation ensures that air holes remain unclogged while maintaining dust filtration precision, thereby preserving inhalation force without requiring manual cleaning interventions.
2Manufacturing precision
If a grill part is disposed in the outlet part to filter dust, then dust cannot escape from the outlet part, but the user must directly remove dust from the grill part which is inconvenient
Solution Approach 1:
The patent implements the self-service principle by enabling the grill part to automatically remove dust through rotation driven by air flow. The system serves itself by using the existing air current to rotate the grill part, which automatically prevents dust accumulation and eliminates the need for user intervention in dust removal. This maintains dust filtration precision while significantly improving maintenance convenience.
3Manufacturing precision
If the air through holes are clogged by dust, then dust filtration is maintained, but the inhalation force of the vacuum cleaning device is lowered
Solution Approach 1:
The patent applies dynamics by implementing a rotatable grill part that moves in response to air flow. This rotation prevents dust from clogging the air through holes, ensuring that the inhalation force remains high. The system dynamically adapts to dust accumulation tendencies by rotating the grill part, thereby maintaining both dust filtration precision and powerful inhalation force without trade-offs.
Applied Scientific Principles
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 design prevents dust accumulation on the grill surface, maintains suction force, and simplifies cleaning by rotating dust away from the grill, enhancing user convenience and cleaning efficiency.

AI summary
A vacuum cleaning device 1 having a cyclone dust collector 40 . Foreign substances can be prevented from being attached on an outer circumferential surface of a grill 63 located at an outlet part 85, so that an inhalation force of the vacuum cleaning device 1 can be prevented from being lowered. Also, foreign substances collected in the cyclone dust collector 40 can be easily removed. The cyclone dust collector 40 includes a cyclone chamber 53 in which air introduced through an inlet part 91 is whirled and dust is separated from the air; an outlet part 85 disposed so that the air from which the dust is separated is discharged from the cyclone chamber 53; and a grill 63 that is rotatably disposed in the outlet part 85.
