Solution Overview

Problem

Existing aerosol-generating articles for heating-type devices lack a segmented design that effectively combines nicotine and non-nicotine aerosol-generating materials, leading to inadequate atomization and smoking experience.

Innovation Solution

An aerosol-generating article comprising a first segment with a moisturizing material (at least 30 mg by weight) excluding nicotine and a second segment containing nicotine, where both segments are heated by a single heater, with the second segment's unheated portion filtering the aerosol to enhance the smoking experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single heater is used to heat both nicotine and non-nicotine aerosol-generating materials, then device complexity is reduced, but aerosol quality and atomization effectiveness deteriorate

Engineering Contradiction:

Improveheater structureVSAvoidaerosol quality

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The aerosol-generating article is divided into multiple segments: a first segment containing non-nicotine aerosol-generating material and a second segment containing nicotine aerosol-generating material. This segmentation allows each material to be heated and processed separately, maintaining aerosol quality while using a single heater structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the aerosol-generating article are designed with different material compositions and properties. The first segment uses moisturizing materials for smooth atomization, while the second segment contains nicotine for pharmacological effect. This local differentiation ensures optimal performance for each function within a single heater system.

Inventive Principle:

Principle #3Local quality

2Productivity

If aerosol-generating material is heated to high temperature for effective atomization, then atomization effectiveness is improved, but harmful factors generated during heating increase

Engineering Contradiction:

Improveatomization effectivenessVSAvoidheating byproducts

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent optimizes the composition parameters of the aerosol-generating material, specifically incorporating moisturizing materials in controlled amounts. This parameter optimization enables effective atomization at reduced heating temperatures, minimizing harmful byproducts while maintaining productivity.

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If nicotine content is increased to satisfy user demand, then user satisfaction is improved, but harmful factors in the aerosol increase

Engineering Contradiction:

Improveuser satisfactionVSAvoidnicotine-related harm

Core Design Contradiction:

Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The article separates nicotine-containing material into a distinct second segment, isolated from the non-nicotine first segment. This segmentation allows controlled delivery of nicotine to satisfy user demand while maintaining separate processing conditions that minimize harmful factor generation.

Inventive Principle:

Principle #1Segmentation

4Reliability

If moisturizing material amount is increased to improve aerosol quality, then aerosol quality is improved, but material cost and weight increase

Engineering Contradiction:

Improveaerosol qualityVSAvoidarticle weight

Core Design Contradiction:

ReliabilityVSWeight of moving object

Solution Approach 1:

The patent determines the optimal amount of moisturizing material through parameter optimization. By precisely controlling the moisturizing material content in the first segment, the patent achieves excellent aerosol quality without excessive weight gain, balancing performance and portability.

Inventive Principle:

Principle #35Parameter changes
