Vacuum Cleaner Compression Unit with Air-Guided Dust Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaners face issues with dust accumulation on the upper portion of the compression member, leading to interference with the air cyclone flow and deformation of the compression member, making it difficult to restore to the initial position and affecting cleaning performance.
Innovation Solution
A cleaner design featuring a cleaning unit with a guide fence and connection bracket that blocks air flow to prevent dust accumulation, a discharge inclining surface to slide dust downward, and a reinforced connection part to maintain the cleaning unit's position and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a compression member is mounted to surround the filter part and raise/lower to compress dust, then dust can be compressed in the dust collection part, but dust accumulates on the upper portion of the compression member and connection parts, causing the compression member to fail to restore to its initial position
Solution Approach 1:
The guide flow path is designed to guide air flow downward along the inner surface of the dust collection part before the compression member operates, preventing dust from accumulating on the upper portion of the compression member and connection parts in advance. This preliminary air flow arrangement ensures that when the compression member raises and lowers, dust does not interfere with its restoration to the initial position.
2Productivity
If the compression member is raised and lowered frequently to compress dust, then dust collection performance is maintained, but the connection part between the compression member and manipulation lever becomes deformed due to dust accumulation and mechanical stress
Solution Approach 1:
The guide flow path extracts the harmful air flow that would otherwise carry dust to the connection part. By redirecting the air flow along the inner surface of the dust collection part, the connection part is isolated from dust accumulation, preventing deformation and maintaining structural integrity even with frequent raising and lowering operations.
3Use of energy by moving object
If air flow is allowed to reach the upper side of the compression member during cleaner operation, then air circulation is maintained, but dust accumulates on the connection part between the compression member and manipulation lever
Solution Approach 1:
The guide flow path creates a localized air flow pattern where air moves downward along the inner surface of the dust collection part rather than reaching the upper side of the compression member. This local redirection of air flow maintains necessary air circulation while preventing dust from being carried to the connection part, thus eliminating the harmful effect of dust accumulation.
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 design effectively compresses dust within the dust container without opening it, maintains air cyclone flow, and prevents deformation of the connection part, enhancing the cleaner's performance and durability.
Implementation Method 1
at least a portion of the cleaning unit at an initial position may be connected to an air introduction path of the housing, and thus the cleaning unit may guide a flow path of air
Implementation Method 2
a discharge inclining surface to slide dust downward
Implementation Method 3
a compression member (a cleaning part) that can compress dust accumulated in a dust collection part is mounted inside the dust collection part, and the dust is compressed by lowering the compression member
Implementation Method 4
may be restored to an initial position thereof by an elastic force of an elastic member such as a spring
Implementation Method 5
a cleaner which has a cleaning unit capable of compressing dust accumulated inside a dust container without opening the dust container
