Solution Overview

Problem

Conventional dust collecting apparatuses face issues with reduced suction force due to accumulation of large volumes of dirt, lack of visibility into the cyclone chamber without disconnection, and increased size requirements for larger dust collection capacity.

Innovation Solution

A compact dust collecting apparatus with a cyclone body arranged eccentrically within a dust canister body, featuring a transparent common or protruded portion for visibility and a helical guide for enhanced rotating force, allowing for easy observation of dirt flow and increased dust collection capacity without enlarging the apparatus size.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If the dust collection chamber is made larger to increase dust collection capacity, then the amount of dust collected increases, but the size of the dust collecting apparatus increases

Engineering Contradiction:
Improveamount of dust collectedVSAvoidsize of dust collecting apparatus
Core Design Contradiction:
Quantity of substanceVSVolume of stationary object

Solution Approach 1:

The cyclone body is nested within the dust canister body, with the cyclone chamber positioned inside the dust collection chamber. This nested configuration allows the dust collection chamber to be enlarged for increased capacity while maintaining a compact overall apparatus size, as the components utilize shared spatial volume efficiently

Inventive Principle:
Principle #7Nested doll (Nesting)

2Productivity

If the cyclone chamber is positioned in the center of the dust collection chamber, then the dust flow path is optimized, but the visibility into the cyclone chamber from outside becomes poor

Engineering Contradiction:
Improvedust flow efficiencyVSAvoidvisibility into cyclone chamber
Core Design Contradiction:
ProductivityVSDifficulty of detecting and measuring

Solution Approach 1:

The cyclone body is positioned eccentrically within the dust collection chamber rather than at the center. This asymmetric positioning creates a common portion between the cyclone body and dust canister body that is exposed to the outside, enabling visibility into the cyclone chamber while maintaining optimized dust flow paths through the cyclone structure

Inventive Principle:
Principle #4Asymmetry

3Quantity of substance

If a large volume of dirt accumulates in the cyclone chamber, then the dust collection capacity increases, but the suction force decreases due to pressure loss

Engineering Contradiction:
Improvevolume of dirt collectedVSAvoidsuction force
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The transparent common portion of the cyclone body enables visual feedback about the dirt accumulation level in the cyclone chamber. Users can observe when the cyclone chamber needs emptying, allowing timely maintenance to prevent suction force degradation while maximizing dust collection capacity

Inventive Principle:
Principle #23Feedback

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

AI summary

A dust collecting apparatus which is removably connected to a cleaner body is provided. The apparatus includes a cyclone body which forms a cyclone chamber and is in fluid communication with an air inlet passage on one side thereof; an exit pipe which is protruded from a bottom of the cyclone body to an upper side of the cyclone chamber; and a dust canister body which forms a dust collection chamber between the cyclone body and the dust canister body . The cyclone body is arranged eccentrically within the dust collection chamber so that a portion of the cyclone body has a common portion in contact with a portion of the dust canister body. The common portion is made of transparent materials to see through the cyclone chamber.
