Solution Overview

Problem

Existing vacuum cleaners face challenges such as difficulty in separating and emptying the dust container, complex structure leading to fabrication issues, poor dust separation efficiency due to dust flying back, and different cleaning frequencies for the dust container and separator, making it hard to inspect the dust separator and reduce air flow resistance.

Innovation Solution

A vacuum cleaner design with a detachable dust container and dust separator that can be easily coupled and decoupled, featuring a cyclone unit and filter as a single assembly, with a transparent dust container for easy dust inspection and a simplified air flow path to reduce resistance and noise, allowing for separate mounting directions and a body cover for exterior appearance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the dust container and dust separator are formed as one unit, then the structure is integrated, but the weight increases and emptying becomes difficult

Engineering Contradiction:
Improvestructural integrationVSAvoidweight of dust container
Core Design Contradiction:
Stability of the object's compositionVSWeight of moving object

Solution Approach 1:

The dust container is divided into a container body and a lid that can be separated from each other. The lid can be detached from the container body to empty dust, while the container body remains attached to the cyclone separator. This segmentation allows easy emptying without moving the entire heavy unit.

Inventive Principle:
Principle #1Segmentation

2Stability of the object's composition

If the dust container and dust separator are formed as one unit, then the structure is integrated, but the complexity of fabrication increases

Engineering Contradiction:
Improvestructural integrationVSAvoidfabrication complexity
Core Design Contradiction:
Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The dust container is divided into a container body and a lid that can be separated from each other. The lid can be detached from the container body to empty dust, while the container body remains attached to the cyclone separator. This segmentation allows easy emptying without moving the entire heavy unit.

Inventive Principle:
Principle #1Segmentation

3Stability of the object's composition

If the dust container and dust separator are formed as one unit, then the structure is integrated, but dust flying back reduces separation efficiency

Engineering Contradiction:
Improvestructural integrationVSAvoiddust separation efficiency
Core Design Contradiction:
Stability of the object's compositionVSReliability

Solution Approach 1:

The lid is extracted as a separate component from the container body. The lid can be removed to empty dust from the container body, preventing dust from flying back into the cyclone separator during emptying operations.

Inventive Principle:
Principle #2Taking out (Extraction)

4Stability of the object's composition

If the dust container and dust separator are formed as one unit, then the structure is integrated, but different cleaning frequencies make maintenance difficult

Engineering Contradiction:
Improvestructural integrationVSAvoidmaintenance convenience
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The dust container is divided into a container body and a lid that can be separated from each other. The lid can be detached from the container body to empty dust, while the container body remains attached to the cyclone separator. This segmentation allows easy emptying without moving the entire heavy unit.

Inventive Principle:

5Stability of the object's composition

If the dust container and dust separator are formed as one unit, then the structure is integrated, but air flow resistance increases

Engineering Contradiction:

Core Design Contradiction:
Stability of the object's compositionVSLoss of energy

Solution Approach 1:

The lid is extracted as a separate component from the container body. The lid can be removed to empty dust from the container body, preventing dust from flying back into the cyclone separator during emptying operations.

AI summary

A vacuum cleaner is provided, and in particular, a vacuum cleaner having a dust container that holds dust, and a dust separator that separates the dust from air. The vacuum cleaner may, include a body including a fan mounting portion configured to receive a fan mounted thereto, a dust separator provided to one side of the fan mounting portion that draws in air by a suction force of the fan to separate dust from the air by a cyclone principle, and a dust container provided to or at an outside of the dust separator and separable from the dust separator, that holds the dust separated at the dust separator.
