Vacuum Dust Container Rail Blocking for Smooth Compression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners with dust compression functions face issues where dust accumulates in the rail parts, obstructing the movement of the dust compression part, requiring excessive force to operate, which can lead to component damage and inefficient dust collection.
Innovation Solution
A vacuum cleaner design that includes an elevation groove in the dust container with a blocking mechanism to prevent dust from entering the rail part, allowing smooth operation of the movable and transfer parts, and an elastic member to assist in the dust compression process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a dust compression part is provided inside the dust container to compress dust, then the volume of dust is reduced and the dust container does not need to be emptied frequently, but dust enters the rail part along which the dust compression part moves, obstructing its movement
Solution Approach 1:
The dust container interior is segmented into a dust storage space and a rail part by introducing a partition wall. This partition wall extends from the inner bottom surface of the dust container upward along the rail part, creating a physical barrier that separates the dust compression area from the movement path of the dust compression part, preventing dust from entering the rail part while maintaining the dust compression function.
2Quantity of substance
If the dust compression part descends to compress dust, then dust volume is reduced, but the rail part above the dust compression part is opened to the outside allowing dust to be introduced into the gap
Solution Approach 1:
The partition wall is preliminarily constructed to extend along the rail part before the dust compression operation begins. This pre-established barrier prevents dust from entering the rail part during the compression process, eliminating the need for additional protective measures during operation.
3Ease of operation
If dust enters the rail part, then the dust acts as an obstacle to elevate the dust compression part, requiring large force to be applied by the user, but this large force may damage components such as the dust container or dust compression part
Solution Approach 1:
The partition wall divides the dust container interior to create a dedicated dust storage zone separated from the rail part. This segmentation ensures that dust remains in the storage zone and does not enter the rail part, eliminating obstacles during elevation and reducing the force required by the user while preventing component damage.

Provided is a cleaner. The cleaner includes a housing provided with a dust container at a lower side thereof having a suction opening, a filter part configured to filter dust from air suctioned through the suction opening, the filter being spaced apart from an inner circumferential surface of the housing, an air guide configured to guide the air passing through the filter part in an inner region of the filter part to a suction motor configured to generate suction force, a movable part configured to be elevated between a first position and a second position in a space between the outside of the filter part and the inner circumferential surface of the housing, a manipulation part of which at least a portion is exposed to outside of the housing, the manipulation part being elevated by user's manipulation, and a transfer unit of which at least a portion is accommodated in the housing, the transfer unit being configured to connect the manipulation part to the movable part.
