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 efficient dust separation and easy maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a grill part is disposed in the outlet part with air through holes, then dust having more than a predetermined size cannot escape from the outlet part, but the air through holes become clogged by dust attached to the outer circumferential surface of the grill part, causing inhalation force to be lowered

Engineering Contradiction:
Improvedust filtration effectivenessVSAvoidinhalation force
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The grill is made rotatable around the rotational axis of the fan, transforming from a static structure to a dynamic one. The inhalation force generated by the fan rotates the grill, causing the air through holes to continuously change orientation and prevent dust accumulation that would clog the holes, thereby maintaining both filtration effectiveness and inhalation force.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The rotational movement of the grill creates periodic action where the air through holes continuously sweep through different angular positions. This periodic motion prevents dust from settling and clogging the holes, as the holes are constantly moving relative to the dust particles, maintaining consistent airflow and filtration performance.

Inventive Principle:
Principle #19Periodic action

2Reliability

If a grill part is disposed in the outlet part to filter dust, then dust is filtered from the air, but dust accumulates on the outer circumferential surface of the grill part requiring manual cleaning by the user

Engineering Contradiction:
Improvedust filtration effectivenessVSAvoidmaintenance convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The grill rotates automatically due to the inhalation force generated by the fan during operation. This dynamic rotation prevents dust from accumulating on the outer circumferential surface, as the surface is continuously moving and dust particles cannot settle. Users no longer need to manually clean the grill, significantly improving maintenance convenience while maintaining filtration effectiveness.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system performs self-cleaning through the rotational movement of the grill. The inhalation force that drives the fan also rotates the grill, creating a self-service mechanism where the system automatically prevents dust accumulation without requiring user intervention for maintenance, thereby improving ease of operation.

Inventive Principle:
Principle #25Self-service

3Device complexity

If the grill is fixed in the outlet part, then the structure is simple, but dust accumulates on the grill surface reducing inhalation force and requiring frequent cleaning

Engineering Contradiction:
Improvegrill mounting structureVSAvoidinhalation force
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The grill is designed to rotate around the fan's rotational axis, adding only one degree of freedom to the structure. This simple dynamic modification allows the grill to self-clean through rotation driven by the existing inhalation force, preventing dust accumulation and maintaining high productivity without significantly increasing device complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The grill uses the inhalation force generated by the fan to rotate itself, creating a self-service mechanism. The system leverages its own operational force to prevent dust accumulation, eliminating the need for separate cleaning mechanisms or complex structures while maintaining consistent inhalation force and productivity.

Inventive Principle:
Principle #25Self-service

AI summary

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