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 efficient dust separation and easy maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a grill part with air through holes is disposed in the outlet part, 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
Solution Approach 1:
The patent applies the dynamics principle by making the grill part rotatable instead of stationary. The grill is connected to the fan and rotates together with it, allowing dust accumulated on the outer circumferential surface to be automatically removed by the rotating motion. This dynamic solution prevents clogging of air through holes while maintaining dust filtration effectiveness and inhalation force.
2Reliability
If a grill part is disposed in the outlet part to filter dust, then dust separation is improved, but manual cleaning is required when dust accumulates on the outer circumferential surface, which is inconvenient
Solution Approach 1:
The patent applies the self-service principle by enabling the grill to automatically remove dust through its own rotation. The dust removal function is integrated into the normal operation of the vacuum cleaner - the fan-driven rotation of the grill automatically clears accumulated dust without requiring manual intervention. This makes the system self-maintaining during operation.
3Productivity
If the grill is made rotatable mounted on a fan, then dust accumulation on the grill surface is prevented and inhalation force is maintained, but the device complexity increases
Solution Approach 1:
The patent applies the merging principle by combining the grill with the fan assembly. The grill is mounted on the fan housing and rotates together with the fan, sharing the same rotational mechanism. This integration eliminates the need for separate rotation mechanisms or additional driving components, reducing overall device complexity while achieving the benefit of automatic dust removal and consistent inhalation force.
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 maintains a consistent inhalation force by preventing dust accumulation on the grill surface, enhancing cleaning efficiency and simplifying maintenance by allowing easy removal of collected dust without manual intervention.
Implementation Method 1
a cyclone type dust collecting unit in which foreign substances are filtered during a cyclone flow of air
Implementation Method 2
a cyclone chamber, coupled to the inlet part, to circulate the air and to separate dust from the air
Implementation Method 3
Vacuum cleaning devices are devices that inhale (or intake) air by an inhalation (or intake) force generated by a fan and a motor
Implementation Method 4
a grill, rotatably disposed in the outlet part, to rotate and to filter the dust from the air

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.
