Cyclone Cleaner Movable Frame Design to Reduce Dust 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 to accumulate, leading to poor movement and potential blockage of 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 air from directly moving into the air flow path at the standby position, ensuring smooth movement and efficient 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 of the dust bin is reduced resulting in reduction of dust separation space
Solution Approach 1:
The dust compression part is designed to move between a standby position (first position) where it does not block the opening and a compression position (second position) where it compresses dust. This dynamic positioning resolves the contradiction by allowing the part to be out of the way during normal operation while still enabling compression when needed.
Solution Approach 2:
The movable part is divided into a frame portion and a dust compression portion that can move relative to each other. The frame portion remains at the standby position to maintain dust bin space, while the dust compression portion can extend to perform compression, separating the spatial requirements of each function.
2Length of moving object
If the dust compression part is located higher than the opening, then the movable part can be accommodated, but the distance for vertical movement is reduced resulting in reduction of dust compression performance
Solution Approach 1:
The dust compression part is designed to move not only vertically but also horizontally toward the cyclone part. This multi-dimensional movement allows the compression portion to reach the dust accumulation area without requiring the entire structure to be positioned lower, maintaining both accommodation and compression performance.
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 can be cleaned, but dust may be caught between the dust compression part and the inner circumferential surface causing rough vertical movement
Solution Approach 1:
The dust compression part is extracted from direct contact with the dust bin's inner circumferential surface. Instead, it compresses dust through contact with the dust accumulation area itself or through airflow, eliminating the harmful friction and dust trapping while maintaining cleaning functionality.
Solution Approach 2:
Airflow serves as an intermediary between the dust compression part and the dust bin inner surface. The airflow carries dust particles away while the compression part operates, preventing direct contact that would cause dust accumulation and movement resistance.
4Productivity
If the movable part is operated downward during suction, then dust compression can be performed, but dust accumulates on the upper side of the movable part causing blockage of the opening
Solution Approach 1:
The system performs preliminary dust removal from the upper side of the movable part before compression occurs. The airflow path is designed to prevent dust accumulation in advance, ensuring that when compression happens, the opening remains clear and blockage is prevented.
Solution Approach 2:
The airflow path maintains continuous operation throughout the compression cycle. Airflow continues to move dust particles away from the opening area even when the compression part moves downward, ensuring uninterrupted dust removal and preventing blockage during compression operations.
