Solution Overview

Problem

Existing aerosol generating devices that use liquid compositions face inconvenience when the liquid is depleted, requiring refilling or replacement, and there is a need for a device that can provide various flavors and be conveniently reused.

Innovation Solution

An aerosol generating article impregnated with different liquid compositions, featuring segments for generating aerosol, a cooling portion, and a filter portion, which can be removably inserted into an aerosol generating device with a heater.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If liquid composition is stored in the aerosol generating device, then aerosol can be generated continuously, but the device becomes inconvenient when liquid is depleted requiring refilling or replacement

Engineering Contradiction:

Improvecontinuous aerosol generationVSAvoidconvenience when liquid is depleted

Core Design Contradiction:

Duration of action of moving objectVSEase of operation

Solution Approach 1:

The aerosol generating article is divided into multiple segments (first segment, second segment, third segment) where each segment contains different liquid compositions. This segmentation allows the article to provide multiple flavors and extends usage duration without requiring device refilling, as the entire article can be removed and replaced as a single unit when depleted.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention uses disposable aerosol generating articles that are pre-filled with liquid compositions. When the liquid is depleted, the entire article is discarded and replaced with a new pre-filled article, eliminating the need for user refilling operations and improving convenience despite the short lifespan of each individual article.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

2Adaptability or versatility

If multiple liquid compositions are stored to provide various flavors, then flavor variety is improved, but liquid leakage risk increases

Engineering Contradiction:

Improveflavor varietyVSAvoidliquid leakage risk

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

Different liquid compositions are stored in separate segments (first segment for first liquid composition, second segment for second liquid composition, etc.). This physical segmentation isolates different liquids, preventing them from mixing and reducing leakage risk between flavors while still providing variety when the article is used.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Each segment is enclosed by a wrapper (first wrapper, second wrapper) that acts as a flexible barrier. These wrappers contain the liquid compositions and prevent leakage while allowing the article to be inserted into and removed from the heating device. The flexible sealing structure maintains integrity during handling and use.

Inventive Principle:

Principle #30Flexible shells and thin films

3Ease of operation

If the aerosol generating article is made removable for convenient replacement, then ease of operation is improved, but device complexity increases

Engineering Contradiction:

Improveconvenient replacementVSAvoidreceiving space structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The receiving space in the aerosol generating device is designed with universal functionality to accommodate the removable aerosol generating article. It provides both the heating function (containing the heater) and the reception function (holding the removable article), eliminating the need for separate complex mechanisms while enabling convenient replacement.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

An aerosol generating article includes: a first segment impregnated with a first liquid composition; a second segment impregnated with a second liquid composition that is different from the first liquid composition; a cooling portion configured to allow an aerosol generated in the first segment or the second segment, to pass therethrough and cool the aerosol; and a filter portion having a hollow through which the aerosol that passed through the cooling portion flows.
