Solution Overview

Problem

Current non-combustible aerosol provision systems face challenges in efficiently heating aerosol-generating materials without combustion, particularly in achieving uniform heat distribution and minimizing the risk of flammability in components.

Innovation Solution

The aerosol-generating component comprises a first sheet of aerosol-generating material and a second sheet of heating material heatable by a varying magnetic field, wrapped in a paper wrapper with low permeability to prevent combustion, and can be formed into strips or layers for enhanced heat transfer and safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If conventional heating methods are used, then heating efficiency may be improved, but uniform heat distribution and flammability risk control deteriorate

Engineering Contradiction:

Improveheating efficiencyVSAvoiduniform heat distribution and flammability control

Core Design Contradiction:

PowerVSReliability

Solution Approach 1:

The heating element is divided into multiple separate strips distributed throughout the aerosol-generating material, rather than using a single centralized heating source. This segmentation allows heat to be distributed more uniformly across the material, preventing localized overheating and combustion while maintaining overall heating efficiency.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the aerosol-generating material are heated independently through distributed heating strips, allowing each local area to reach appropriate heating temperatures without causing combustion. This enables non-uniform heating patterns that are safe and effective for aerosol generation.

Inventive Principle:

Principle #3Local quality

2Ease of operation

If permeable wrapper material is used, then breathability and aerosol delivery are improved, but flammability risk increases

Engineering Contradiction:

Improvebreathability and aerosol deliveryVSAvoidflammability risk

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The wrapper material's permeability parameter is optimized to a specific range (10-500 Coresta units) that balances breathability for aerosol delivery with sufficient flammability resistance. This parameter change allows the wrapper to perform its protective function while still enabling proper aerosol generation and user inhalation.
