Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a liquid composition is stored in the aerosol generating device, then aerosol can be generated by heating the liquid composition, but the liquid composition has to be additionally injected or a new device has to be purchased when exhausted

Engineering Contradiction:

Improveflavor varietyVSAvoidrefilling convenience

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The aerosol generating article is divided into multiple segments (first segment, second segment, etc.), where each segment can be independently impregnated with different liquid compositions. This segmentation allows the article to provide various flavors while enabling easy replacement of individual segments when liquid composition is exhausted, eliminating the need for refilling or purchasing new devices.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The aerosol generating article is designed as a disposable unit that is pre-impregnated with liquid compositions. When the liquid composition in a segment is exhausted, the entire article can be easily discarded and replaced, or individual segments can be replaced, providing convenient usage without the complexity of refilling systems.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

2Reliability

If the filter is made with high density to filter aerosol, then filtration efficiency is improved, but the absorption resistance becomes too high providing unsatisfactory smoking impression

Engineering Contradiction:

Improvefiltration efficiencyVSAvoidabsorption quality

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The filter is designed with non-uniform density, where different portions of the filter have different densities. This local quality variation allows the filter to provide sufficient filtration efficiency in certain areas while maintaining lower absorption resistance in other areas, ensuring both effective filtration and satisfactory smoking impression.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The filter utilizes porous materials with controlled pore structures to achieve effective aerosol filtration while maintaining appropriate permeability. The porous structure allows aerosol to pass through efficiently while filtering harmful particles, balancing filtration efficiency with absorption quality.

Inventive Principle:

Principle #31Porous materials

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 cooler configured to cool aerosol by allowing the aerosol, generated from the first segment or the second segment, to pass through the cooler; and a filter configured to filter the aerosol by allowing the aerosol having passed through the cooler to pass through the filter, wherein at least a portion of the filter is recessed to thereby form a cavity in the filter.
