Cyclone Cleaner Movable Dust Compression Frame to Prevent Bin Blockage
Find Innovative SolutionsGenerate Solutions
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 when dust accumulates on the upper side of the compression part.
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 air from directly moving into the airflow 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 dust compression part can be accommodated in the dust bin, but the internal space of the dust bin is reduced and dust separation space is reduced
Solution Approach 1:
The dust compression part is designed to be movable between a standby position (higher, outside the dust bin) and a compression position (lower, inside the dust bin). This dynamic positioning allows the system to optimize both dust bin internal space during normal operation and dust compression functionality when needed, resolving the contradiction between accommodation and space utilization.
Solution Approach 2:
The dust compression part is divided into multiple segments including a frame, compression members, and guiding members. This segmentation allows the compression mechanism to be compact when retracted at standby position, minimizing the space it occupies outside the dust bin, while still providing effective compression when deployed inside the dust bin.
2Device complexity
If the dust compression part is located higher than the opening, then the dust compression part structure is simplified, but the distance for vertical movement is reduced resulting in reduced dust compression performance
Solution Approach 1:
The movable design allows the dust compression part to achieve a long vertical movement distance by traveling from a standby position above the dust bin opening to a compression position deep inside the dust bin. This dynamic range provides sufficient compression distance for effective dust compression while keeping the structure relatively simple through the use of guiding members and linkages.
3Ease of operation
If the dust compression part moves in contact with the inner circumferential surface of the dust bin, then the inner circumferential surface is cleaned, but dust may be caught between the dust compression part and the inner circumferential surface causing rough vertical movement
Solution Approach 1:
Guiding members are introduced as intermediary components between the dust compression part and the dust bin inner circumferential surface. These guiding members provide a dedicated track or pathway for the compression part to move along, ensuring smooth vertical movement while preventing dust from becoming trapped between the compression part and the bin wall. The guiding members effectively mediate the interaction between the moving compression mechanism and the stationary bin structure.
4Productivity
If the dust compression part is lowered and rises during suction, then dust accumulation on the upper side of the dust compression part occurs, but this can block the opening and prevent smooth movement
Solution Approach 1:
The guiding members extract or separate the movement function from the compression part itself, providing a dedicated pathway that prevents dust accumulation from interfering with the vertical movement. By taking out the guiding function as a separate component, the system ensures that the movable part can rise and fall smoothly during suction operations even when dust accumulates on its upper surface, preventing blockages and maintaining reliable operation.

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 and prevents blockages, maintaining smooth operation even when dust accumulates on the movable part, improving the overall cleaning efficiency.
Implementation Method 1
a cyclone part configured to separate dust from air introduced through the suction opening
Implementation Method 2
an air flow path through which air flows so that dust accumulated in the frame falls from the movable part in the process of moving to the second position or returning from the second position to the first position
