Solution Overview
Problem
Existing cleaners face issues with dust compression and discharge efficiency, as well as smooth operation and maintenance, due to design flaws such as clogged air flow paths and cumbersome manipulation mechanisms in prior art references.
Innovation Solution
A cleaner design featuring a cyclone part for dust separation, a movable part for easy dust discharge, a filter part for air filtration, and a transfer part connecting the manipulation mechanism to the movable part, which minimizes eddy currents and allows for smooth vertical movement, enhancing dust collection and filtration efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If multiple holes are provided in the cyclone cover for air flow, then air circulation is improved, but dust plugs the holes causing reduced separation performance
Solution Approach 1:
The patent extracts the air flow path from the cover holes and relocates it to the side wall of the cyclone chamber. This eliminates the problem of dust plugging the holes while maintaining air circulation, as the side wall opening is positioned where dust concentration is lower and does not obstruct airflow.
Solution Approach 2:
The patent introduces an intermediary structure (the side wall opening) that mediates between the need for air flow and the prevention of dust accumulation. This opening serves as an alternative pathway that avoids the dust-prone area near the bottom where the original holes were located.
2Ease of operation
If the base rotates to open the dust collector for cleaning, then access to the cover is enabled, but the cleaning operation becomes cumbersome and difficult
Solution Approach 1:
The patent implements a self-cleaning mechanism where the cyclone chamber structure itself facilitates easy access. The side wall opening is designed to be accessible without requiring base rotation, allowing users to clean the cover directly while the cleaner is in its normal operating position, thus eliminating the time-consuming rotation step.
3Reliability
If dust is collected at low density in the dust collector, then dust separation is effective, but dust must be frequently removed to maintain performance
Solution Approach 1:
The patent applies a compression mechanism that dynamically changes the dust storage conditions. The movable part can be lowered to compress the accumulated dust, increasing its density and reducing the volume occupied. This allows the dust collector to maintain high separation efficiency while also increasing the effective storage capacity, reducing the frequency of dust removal.
4Ease of operation
If the manipulation lever is disposed outside the dust separation chamber, then external manipulation is enabled, but a slot must be provided in the chamber allowing internal air and dust leakage
Solution Approach 1:
The patent nests the manipulation lever within the handle structure, which itself is part of the cleaner body. This nested arrangement allows the lever to be accessible from the outside while being protected by the handle housing, eliminating the need for a slot in the dust separation chamber and preventing air and dust leakage.
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 cleaner effectively compresses and discharges dust with reduced maintenance needs, improving air flow efficiency and user convenience by allowing easy manipulation of the movable part and minimizing interference with peripheral structures.

AI summary
A vacuum cleaner includes a suctioning unit, a main body including a cyclone unit for separating dust from the air suctioned through the suctioning unit, a body forming a dust container for storing the dust separated by the cyclone unit, and a body cover for opening and closing the lower side of the body. A filter unit is arranged in the body for filtering air. An actuating unit is configured to move in the body along a space between the outside of the filter unit and the inner circumferential surface of the body.
