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

VSEngineering 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

Engineering Contradiction:
Improvedust filtration precisionVSAvoidinhalation force
Core Design Contradiction:
Manufacturing precisionVSReliability

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.

Inventive Principle:
Principle #15Dynamics

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

Engineering Contradiction:
Improvedust filtration precisionVSAvoidmaintenance convenience
Core Design Contradiction:
Manufacturing precisionVSEase of operation

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.

Inventive Principle:
Principle #25Self-service

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

Engineering Contradiction:
Improvedust filtration precisionVSAvoidinhalation force
Core Design Contradiction:
Manufacturing precisionVSPower

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.

Inventive Principle:
Principle #15Dynamics

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.
