Solution Overview

Problem

Current vacuum cleaners with cyclone dust collecting devices require users to manually remove and clean the dust bin, which is cumbersome, and disposable dust bags lead to economic losses and environmental waste.

Innovation Solution

A device that connects a general garbage bag to the dust bin, using a cylindrical upper and lower cover with a locking mechanism and packing to secure and seal the bag, allowing easy separation and disposal of debris.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a dust bin is used to collect debris, then debris can be discharged, but the user must manually open and clean the dust bin which is cumbersome

Engineering Contradiction:
Improveease of debris dischargeVSAvoidtime for cleaning dust bin
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The dust collecting device is divided into an upper dust collecting chamber and a lower dust bin that can be separated. The dust bin can be detached from the dust collecting chamber, allowing users to easily remove and dispose of debris without manually cleaning the entire device. This segmentation enables the dust bin to be treated as a separate, removable container.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If disposable dust bags are used, then debris can be stored, but additional bags must be purchased continuously causing economic losses

Engineering Contradiction:
Improveease of debris storageVSAvoideconomic loss from buying bags
Core Design Contradiction:
Ease of operationVSLoss of substance

Solution Approach 1:

The dust bin is designed to serve multiple functions: it can hold disposable dust bags when needed, but also function as a permanent reusable container. The universal design allows users to choose between using dust bags or directly disposing of debris in the dust bin, providing flexibility and reducing the need for continuous purchase of disposable bags.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If a locking mechanism is added to secure the bag, then the bag is firmly held, but the device complexity increases

Engineering Contradiction:
Improvebag securing reliabilityVSAvoidcomplexity of locking mechanism
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The locking mechanism is designed as a separate, extractable component that can be easily removed or disassembled. The locking protrusions and grooves are simple geometric features that can be manufactured independently and assembled straightforwardly, minimizing the increase in device complexity while still providing reliable bag securing functionality.

Inventive Principle:
Principle #2Taking out (Extraction)
