Solution Overview

Problem

Current vacuum cleaners lack convenience in the dust discharge process, often scattering dust or requiring complex procedures, as they fail to effectively separate and discharge large and fine dust simultaneously.

Innovation Solution

A dust collector with separate first and second dust storing units, utilizing cyclones for separation, and a compression device that rotates to compress dust, allowing simultaneous discharge through a lower cover part that opens both units in the same direction, preventing scattering and simplifying the discharge process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If dust is discharged from a single dust container, then the discharge process is simple, but dust may be scattered to unexpected places and the discharge control is difficult

Engineering Contradiction:
Improvedust discharge processVSAvoiddust scattering
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The dust container is divided into two separate compartments: a first dust container for collecting large dust particles and a second dust container for collecting fine dust particles. This segmentation allows independent control and discharge of different dust types, preventing scattering while maintaining operational simplicity.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If a single dust container is used, then the device structure is simple, but the ability to separate and discharge different dust types is insufficient

Engineering Contradiction:
Improvedust separation and discharge capabilityVSAvoiddust container structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The dust container is segmented into two distinct compartments with separate discharge mechanisms. The first dust container stores large particles and the second stores fine particles, allowing versatile discharge options while maintaining a relatively simple overall structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The second dust container is positioned within or adjacent to the first dust container, creating a nested or integrated structure. This nesting approach increases functional versatility without significantly increasing the overall device footprint or structural complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Ease of operation

If dust is compressed, then the discharge volume is reduced and control is improved, but the compression mechanism adds complexity

Engineering Contradiction:
Improvedust discharge controlVSAvoidcompression device structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The compression device incorporates a rotatable component that can dynamically adjust the compression force applied to the dust in the first dust container. This dynamic mechanism allows flexible control of dust compression while maintaining a relatively simple structural design.

Inventive Principle:
Principle #15Dynamics

AI summary

A dust collector disclosed herein includes a first dust storing unit to collect dust firstly-separated from air by a first cyclone, a second dust storing unit to collect fine dust secondly-separated from the air by second cyclones located above the first cyclone, a lower cover part coupled to a first dust container to form a bottom surface of the first dust storing unit and the second dust storing unit, and rotatable based on the hinge to simultaneously open the first and second dust storing units, such that the dust and the fine dust are simultaneously discharged, and a compression device rotatably connected to the lower cover part so as to rotate in a reciprocating manner to compress the dust collected in the first dust storing unit.
