Solution Overview

Problem

Existing cleaners, particularly horizontal types, suffer from inadequate separation of large-particle garbage and fine dust, leading to entanglement and blockage in dust-collecting cups, resulting in inefficient cleaning.

Innovation Solution

An inverted cone separation device with double dust-collecting cups, featuring a separator with an inverted cone filter and an air duct connecting the cups, effectively separates large-particle garbage from fine dust, preventing entanglement and improving cleaning efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a single dust-collecting cup with simple filtering is used, then the device complexity is low, but the separation effect of large-particle garbage is insufficient and entanglement occurs

Engineering Contradiction:
Improveseparation effectVSAvoiddevice complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The dust collection system is segmented into two separate dust-collecting cups (first and second cups) with distinct functions. The first cup collects large-particle garbage through an inverted cone filter, while the second cup collects fine dust through a regular filter. This segmentation allows each cup to specialize in collecting specific particle sizes, improving separation effectiveness while preventing entanglement of large particles.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The first dust-collecting cup is nested within the second dust-collecting cup, forming a concentric structure. The air duct connects the inner first cup to the outer second cup, allowing airflow from the filter to carry fine dust into the second cup while large particles remain in the first cup. This nested arrangement maximizes space utilization and enables multi-stage separation.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Manufacturing precision

If the filtering system has few filtering layers, then the device complexity is low, but large-particle garbage and fine dust are mixed and cannot be separated

Engineering Contradiction:
Improveseparation effectVSAvoidfiltering layers
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The filtering system is segmented into two distinct filtering stages located in separate cups. The first filtering layer (inverted cone filter) is dedicated to large-particle separation, while the second filtering layer (regular filter) handles fine dust. This segmentation of filtering functions across spatially separated cups achieves effective multi-layer separation without requiring multiple stacked filters in a single location.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If large-particle garbage is collected in the dust-collecting cup, then the cleaning function is simple, but the large-particle garbage is entangled and blocked

Engineering Contradiction:
Improvecleaning efficiencyVSAvoidblockage prevention
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The first dust-collecting cup uses an inverted cone filter configuration where the filter surface is positioned to receive large-particle garbage directly from the airflow. The inverted cone shape directs large particles to the outer wall where they are deposited and collected in the first cup, preventing them from entering the central air duct and causing blockages. This inverted configuration reverses the typical filter arrangement to specifically address large-particle handling.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

Large-particle garbage is extracted from the main airflow stream by the inverted cone filter in the first cup before the air reaches the second cup. By removing large particles in the first stage, the system prevents them from traveling further and causing entanglement or blockage in the air duct or second cup, thereby improving reliability and reducing maintenance needs.

Inventive Principle:
Principle #2Taking out (Extraction)
