Solution Overview

Problem

Existing non-combustible aerosol provision systems face challenges in producing aerosols with desirable properties, such as body and mouthfeel, due to limitations in nicotine delivery and flavor consistency, often resulting in inefficient heating and potential leakage of aerosol-former materials.

Innovation Solution

Incorporating a section of amorphous solid material with high aerosol-former content, which can be heated to a specific temperature to generate aerosol, combined with a portion of aerosol-generating material like tobacco, allowing for separate and optimized heating profiles to enhance aerosol production and flavor release.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If aerosol-former material is used in conventional forms, then aerosol generation is achieved, but leakage occurs and heating efficiency is poor

Engineering Contradiction:

Improveaerosol generation consistencyVSAvoidaerosol-former material leakage

Core Design Contradiction:

ReliabilityVSLoss of substance

Solution Approach 1:

The patent changes the physical state parameter of the aerosol-former material from liquid or crystalline to amorphous solid form. This parameter change eliminates leakage issues while maintaining aerosol generation capability, as the amorphous solid material can be heated to release aerosol without requiring containment structures that prevent leakage.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent utilizes phase transition by heating the amorphous solid material to transform it into aerosol form. The amorphous solid material undergoes a phase transition when heated, releasing the aerosol-forming compounds without requiring liquid handling or containment, thereby preventing leakage while enabling controlled aerosol generation.

Inventive Principle:

Principle #36Phase transitions

2Productivity

If single material is heated, then heating process is simple, but aerosol body and mouthfeel are insufficient

Engineering Contradiction:

Improveaerosol production efficiencyVSAvoidpoor mouthfeel and body

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent segments the consumable into distinct portions: an amorphous solid material portion containing aerosol-forming compounds and a separate tobacco material portion. Each portion can be heated independently or simultaneously, allowing optimization of heating parameters for each material type to achieve both efficient aerosol production and desirable sensory characteristics.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent creates a composite consumable structure combining amorphous solid material with tobacco material. This composite approach allows the system to leverage the aerosol-forming properties of the amorphous solid while simultaneously utilizing the flavor and sensory properties of tobacco, achieving both productivity and sensory quality.

Inventive Principle:

Principle #40Composite materials

3Quantity of substance

If tobacco material is heated alone, then flavor is released, but nicotine delivery is insufficient and odor remains

Engineering Contradiction:

Improvenicotine deliveryVSAvoidodor

Core Design Contradiction:

Quantity of substanceVSObject-generated harmful factors

Solution Approach 1:

The patent merges the amorphous solid material portion with the tobacco material portion into a single integrated consumable. This merging allows simultaneous heating of both materials, combining the nicotine delivery capability of tobacco with the aerosol-forming properties of the amorphous solid, while the controlled heating reduces odor compared to traditional combustion.

Inventive Principle:

Principle #5Merging (Combining)

4Reliability

If conventional aerosol systems are used, then aerosol is generated, but energy consumption is high

Engineering Contradiction:

Improveaerosol generationVSAvoidheating energy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent changes the physical state of the aerosol-former to amorphous solid, which requires less energy to vaporize compared to liquid systems. The amorphous solid material can be heated more efficiently to release aerosol, reducing overall energy consumption while maintaining reliable aerosol generation.

Inventive Principle:

Principle #35Parameter changes
