Solution Overview

Problem

Existing heat-not-burn devices lack user control over the composition of generated aerosol and suffer from uneven release of aerosol-modifying agents, leading to inconsistent sensory experiences.

Innovation Solution

An article for a non-combustible aerosol provision system featuring an aerosol-generating portion with an encapsulated first aerosol-modifying agent and a filter with a selectively releasable second aerosol-modifying agent, allowing for controlled release of these agents through temperature thresholds and user-actuated mechanisms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If an encapsulated aerosol-modifying agent is used in the aerosol-generating portion, then sustained release is achieved, but the release temperature is fixed and cannot be adjusted by the user

Engineering Contradiction:

Improverelease durationVSAvoidrelease control flexibility

Core Design Contradiction:

Duration of action of moving objectVSAdaptability or versatility

Solution Approach 1:

The aerosol-modifying agents are segmented into two distinct types: an encapsulated first agent in the aerosol-generating portion for sustained release, and a second agent in the filter portion for selective release. This segmentation allows each agent to serve a different functional purpose and be controlled independently.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The filter portion acts as an intermediary component that houses the second aerosol-modifying agent in a separate compartment. This intermediary structure enables selective release of the second agent independent of the heating process, providing user control over when and how the agent is released.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Device complexity

If a single aerosol-modifying agent is used, then the device structure is simple, but user control over aerosol composition is limited

Engineering Contradiction:

Improvearticle structureVSAvoidaerosol composition control

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The article is divided into two functional segments: the aerosol-generating portion containing the first aerosol-modifying agent and the filter portion containing the second agent. This segmentation enables independent control and release of each agent, providing users with the ability to adjust aerosol composition without significantly increasing overall device complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the article are assigned different qualities and functions: the aerosol-generating portion is optimized for sustained release through encapsulation, while the filter portion is designed for selective release. This local differentiation allows each component to contribute uniquely to aerosol composition control.

Inventive Principle:

Principle #3Local quality

3Speed

If aerosol-modifying agents are released without encapsulation, then immediate release occurs, but sustained release and consistent sensory experience are not achieved

Engineering Contradiction:

Improverelease speedVSAvoidsensory experience consistency

Core Design Contradiction:

SpeedVSStability of the object's composition

Solution Approach 1:

The first aerosol-modifying agent is pre-encapsulated in the aerosol-generating portion before use. This preliminary encapsulation ensures that the agent is released slowly and sustainably during the heating process, maintaining consistent sensory experience throughout the product's usage life rather than releasing all at once.

Inventive Principle:

Principle #10Preliminary action
