Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cyclone type dust collecting units in vacuum cleaners suffer from low density of accumulated foreign substances, leading to frequent emptying needs, dust generation, and aesthetic issues due to loose accumulation, which complicates cleaning and user convenience.
Innovation Solution
A dust compressing apparatus with a compartment plate and negative pressure system that separates and compresses foreign substances within the dust collecting unit, utilizing airflow passages to efficiently increase the density of collected dust and prevent spreading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If foreign substances are accumulated by gravity in the dust collection container, then the dust collecting unit can separate and collect foreign substances, but the density of accumulated foreign substances is low
Solution Approach 1:
The dust collection container is divided into a first compartment for collecting foreign substances and a second compartment for storing compressed foreign substances, separated by a compartment plate. This segmentation allows the system to first collect dust through gravity in the first compartment, then compress it into the second compartment, thereby increasing the density of stored foreign substances while maintaining the collection function.
Solution Approach 2:
The invention uses a motor to generate negative pressure (suction force) that acts on the compartment plate to compress the foreign substances in the first compartment. This pneumatic approach replaces manual compression and enables high-density storage of foreign substances in the second compartment, resolving the contradiction between collection quantity and storage density.
2Volume of stationary object
If the dust collection container is emptied frequently due to low density accumulation, then the container capacity is maintained, but user convenience is reduced and cleaning becomes more difficult
Solution Approach 1:
The system performs preliminary compression of foreign substances into the second compartment during the normal operation phase. By compressing dust before the container needs to be emptied, the system reduces the frequency of emptying operations and makes subsequent cleaning easier, as compressed dust is less likely to generate airborne particles during removal.
3Device complexity
If foreign substances are loosely accumulated in the dust collection container, then gravity-based collection is simple, but dust is generated during cleaning and appearance becomes unpleasant
Solution Approach 1:
The invention extracts the compression function from the simple gravity-based collection system by introducing a motor-driven compression mechanism. Foreign substances are first collected loosely in the first compartment, then compressed into the second compartment, separating the collection simplicity from the storage density requirement and eliminating dust generation issues.
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 apparatus allows for less frequent and easier removal of collected dust, maintaining cleaner appearance and improving user convenience by compressing dust through a simple manipulation of airflow control.
Implementation Method 1
a compression unit compressing the accumulated foreign substances by moving the compartment plate toward the foreign substance storing compartment
Implementation Method 2
the foreign substances are collected from the air by the cyclone effect
Implementation Method 3
Since the cyclone type dust collecting unit utilizes the gravity to drop the foreign substances

AI summary
There is provided a dust compressing apparatus for a dust collecting unit of a vacuum cleaner. In the dust compressing apparatus, a compartment plate divides an inner space of a dust collection container into an upper foreign substance separating compartment and a lower foreign substance storing compartment, and a branching unit guides airflow. The branching unit includes a motor connection passage directed to a motor generating a negative pressure, a dust collection passage directed to the foreign substance separating compartment, and a compression passage directed to the foreign substance storing compartment. A flow passage control unit controls connections between the passages of the branching unit. A compression unit compresses foreign substances stored in the foreign substance storing compartment by moving the compartment plate to the foreign substance storing compartment using the negative pressure transmitted through the compression passage.
