Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current non-combustible aerosol provision devices face challenges in providing a consumable that efficiently generates aerosol with varying compositions of gelling agents, aerosol-formers, active substances, flavorants, and acids, as existing solutions often result in inconsistent aerosol quality and user experience.
Innovation Solution
A consumable comprising two distinct amorphous solid aerosol-generating materials, each with different compositions of gelling agents, aerosol-formers, and active substances or flavorants, attached to a support for optimal aerosol generation, allowing for separate control of aerosol production based on user preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a single aerosol-generating material is used, then the device structure is simple, but the aerosol composition consistency and quality are poor
Solution Approach 1:
The consumable is divided into two distinct aerosol-generating materials with different compositions. Each material contains specific ratios of gelling agent, aerosol-former, and active substance/flavorant, allowing independent optimization of aerosol generation properties. This segmentation enables consistent aerosol quality by separating functional requirements into dedicated material zones.
2Adaptability or versatility
If multiple aerosol-generating materials with different compositions are used, then the aerosol quality and customization are improved, but the manufacturing complexity increases
Solution Approach 1:
Each aerosol-generating material is formulated with specific local compositions tailored to particular aerosol generation requirements. The first material may optimize for active substance delivery while the second material optimizes for flavorant delivery or aerosol density. This local quality approach enables customization without requiring complex multi-step manufacturing processes.
