Solution Overview

Problem

Existing smoking articles and hybrid devices face challenges in handling and processing amorphous solid aerosolizable materials due to their tacky surfaces, which lead to handling difficulties and inefficient aerosol generation.

Innovation Solution

A laminate aerosol generating material is developed, comprising an aerosol-forming amorphous solid layer attached to a carrier layer that does not adhere to any other surface, using anti-adhesive agents and optimized thickness and density to improve handleability and aerosol delivery.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If amorphous solid aerosolizable material is used, then aerosol generation efficiency is improved, but handling and processing becomes difficult due to tacky surfaces

Engineering Contradiction:

Improveaerosol generation efficiencyVSAvoidhandling difficulty

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

A release liner is introduced as an intermediary between the tacky amorphous solid material and the external environment. The liner provides a non-stick surface that allows the material to be handled, transported, and processed without adhering to surfaces, while still enabling efficient aerosol generation when the liner is removed or pierced during use

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If amorphous solid material is used for aerosol generation, then aerosol formation is enhanced, but manufacturing and processing efficiency decreases

Engineering Contradiction:

Improveaerosol formationVSAvoidmanufacturing efficiency

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The release liner serves as a manufacturing intermediary that enables standard fabrication processes. The liner protects the material during cutting, lamination, and assembly operations, allowing manufacturers to use conventional equipment and techniques while maintaining the integrity of the tacky amorphous solid material

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The product is divided into separate functional layers: the amorphous solid aerosolizable material layer and the release liner layer. This segmentation allows each layer to be optimized independently - the material for aerosol performance and the liner for handling and manufacturing - while being easily combined into a single integrated product

Inventive Principle:

Principle #1Segmentation
