Solution Overview
Problem
Existing cleaners face issues with dust compression efficiency due to the dust compression part being located higher than the opening, reducing the internal space for dust separation and causing dust accumulation, which hampers smooth movement and blocks the opening.
Innovation Solution
A cleaner design with a movable part that includes a frame with inclined bodies forming an air flow path, allowing dust to fall into the dust bin even when the movable part is operated downward, and preventing direct airflow to the cyclone path at the standby position, ensuring smooth operation and effective dust collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the dust compression part is located higher than the opening at standby position, then the movable part can be accommodated in the dust bin, but the internal space for dust separation is reduced and dust compression performance deteriorates
Solution Approach 1:
The dust compression part is designed to be movable between a standby position (higher than the opening) and a dust compression position (lower than the opening). This dynamic positioning allows the system to optimize both dust separation space during standby and dust compression performance during operation, resolving the spatial conflict between accommodation and compression functions.
2Productivity
If the movable part is operated downward during suction, then dust compression can be performed, but dust accumulates on the upper side of the compression part blocking movement and the opening
Solution Approach 1:
The guide groove structure extracts and manages the dust accumulation issue by providing a dedicated pathway for dust to be directed away from the upper side of the compression part. The groove geometry ensures that dust is channeled toward the opening rather than accumulating on surfaces that would obstruct movement.

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 enhances dust compression performance by ensuring dust falls into the bin efficiently, reducing blockages and improving the cleanliness of the inner surfaces, while maintaining smooth movement of the movable part.
Implementation Method 1
a cyclone part configured to separate dust from air introduced through the suction opening
Implementation Method 2
a frame with inclined bodies forming an air flow path, allowing dust to fall into the dust bin

AI summary
A cleaner includes a housing including a suction opening, a cyclone part configured to separate air and dust, and a dust bin configured to store dust separated from air in the cyclone part and a frame disposed to surround an axis of a cyclone flow of the cyclone part in the housing and configured to be movable between a first position and a second position in the housing, wherein the frame includes a first body disposed to face the suction opening at the first position and disposed to be inclined with respect to the axis of the cyclone flow, and an upper end of the first body is located to be the same as or higher than an upper end of the suction opening.
