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 deterioration of performance, as well as difficulty in cleaning and potential deformation of the compression member due to dust accumulation and friction with the dust container.
Innovation Solution
A cleaner design featuring a guide fence and connection bracket with a discharge inclining surface, along with a reinforcement plate, to prevent dust accumulation on the upper surface and enhance the strength of the connection between the cleaning unit and manipulation unit, ensuring efficient airflow and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a compression member is mounted to surround the filter part and scrape off dust while moving toward the base, 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 patent extracts the harmful dust accumulation problem by introducing a separate air ejection path that removes dust-laden air from the compression member area. The air ejection path includes an ejection hole positioned to receive air from the compression member, preventing dust from accumulating on the compression member and connection parts while maintaining the dust compression function.
Solution Approach 2:
The patent introduces air as an intermediary substance to remove dust from the compression member area. Air flows through the dust collection part, picks up dust particles, and ejects them through the ejection hole, preventing dust accumulation that would otherwise hinder the compression member's restoration.
2Productivity
If air flows to the gap between the compression member and inner surface of the dust container, then air circulation is maintained, but dust accumulates on the connection part between the compression member and manipulation lever
Solution Approach 1:
The patent applies local quality by positioning the ejection hole at a specific location that targets the connection part area where dust accumulates. The air flow is directed locally to the connection part through the ejection hole, cleaning dust from this specific area while maintaining overall air circulation in the dust container.
3Productivity
If the compression member is raised and lowered frequently, then dust compression is performed regularly, but dust accumulates on the upper side of the compression member due to falling dust during movement
Solution Approach 1:
The patent implements continuous air flow through the dust collection part and ejection path, maintaining constant dust removal action. This continuous air circulation prevents dust accumulation on the compression member during and between compression operations, ensuring the compression member can always restore to its initial position regardless of operation frequency.
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 allows for effective compression of dust within the dust container without opening it, maintaining airflow and preventing the cleaning unit from failing to return to its initial position, thus improving the cleaner's performance and durability.
Implementation Method 1
The separating device includes a centrifuge that generates one or more cyclones
Implementation Method 2
the compression member may be restored to an initial position thereof by an elastic force of an elastic member such as a spring

AI summary
A cleaner is disclosed. The cleaner includes: a housing having an introduction opening through which air is introduced; a filtering unit configured to be mounted in an inner space of the housing, and defining a dust collection space between the filtering unit and an inner surface of the housing; and a cleaning unit configured to surround the filtering unit, and configured to be raised and lowered inside the dust collection space along with a manipulation unit, wherein, when the cleaning unit is in an initial position, at least a portion of the cleaning unit is connected to an air introduction path extending from the introduction opening to form a guide flow path to guide a flow of introduced air.
