Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaners face issues with dust accumulation in dust containers, requiring frequent emptying and affecting performance due to the design of compression members that block air intake and are prone to deformation, leading to inefficient operation and potential damage.
Innovation Solution
A cleaner design with a cleaning unit that compresses dust within the dust container without opening it, featuring a guide edge that maintains air flow and prevents foreign matter blockage, along with a support rib to stabilize the cleaning ring and reinforce the connection between the cleaning unit and manipulation unit, ensuring efficient operation and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a compression member is mounted to surround the filter part and compress dust, then dust compression is achieved, but air introduction is blocked
Solution Approach 1:
The compression member is divided into multiple compression units arranged along the dust collection chamber. Each compression unit can independently compress dust in different zones, allowing air to pass through gaps between units while still achieving effective dust compression throughout the chamber.
Solution Approach 2:
The compression member is designed to move along the longitudinal axis of the dust collection chamber, maintaining a consistent compression force distribution. This allows the compression member to compress dust effectively while preserving adequate spacing for air flow paths throughout its movement range.
2Productivity
If the compression member is positioned close to the air introduction opening, then dust compression efficiency is improved, but the opening becomes easily blocked by foreign matter
Solution Approach 1:
The compression member is positioned and moves along the longitudinal axis of the dust collection chamber, utilizing the depth dimension rather than blocking the cross-sectional air introduction opening. This spatial arrangement allows the compression member to operate effectively in the dust accumulation zone without interfering with the air intake path.
3Quantity of substance
If the compression member surrounds the entire filter part, then dust compression coverage is maximized, but the structure becomes complex and prone to deformation
Solution Approach 1:
The compression member is segmented into multiple independent compression units distributed along the dust collection chamber. Each unit has a simplified structure that can be easily manufactured and maintained, while the collective arrangement of multiple units provides comprehensive dust compression coverage throughout the chamber.
4Ease of manufacture
If the compression member is designed with a simple structure, then manufacturing is easier, but it becomes prone to deformation and damage
Solution Approach 1:
The compression member is divided into multiple compression units with simple, standardized structures that are easy to manufacture. Each unit can be produced using conventional manufacturing processes, while the modular design allows for easy replacement if deformation or damage occurs, maintaining system durability without requiring complex individual components.

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 surrounding the filtering unit and configured to be raised and lowered. 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 such that the cleaning unit guides a flow of introduced air. A guide edge extends from a lower portion of the cleaning unit toward a bottom of the dust collection space, and a surface of the guide edge facing the inner surface of the housing is inclined.
