Aerosol Generating Material Volatile Component Nicotine Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol generating materials for heat-not-burn products experience inconsistent nicotine release due to rapid initial volatilization followed by a sharp drop-off, leading to an inconsistent user experience.
Innovation Solution
Incorporating a volatile component with a vapor pressure greater than or equal to that of nicotine at 20°C in liquid form into the aerosol generating material, which competes with nicotine for release, thereby controlling and extending the release of nicotine through the material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If aerosol generating material is heated to volatilize nicotine, then nicotine release is achieved, but the release is inconsistent with rapid initial volatilization followed by sharp drop-off
Solution Approach 1:
A volatile component with higher vapor pressure than nicotine is introduced as an intermediary substance. This volatile component competes with nicotine for release during heating, effectively mediating the nicotine release process. The volatile component's faster volatilization rate creates a competitive environment that suppresses rapid nicotine release initially, then allows sustained release as the volatile component depletes, thereby achieving consistent nicotine delivery throughout the heating cycle.
2Stability of the object's composition
If volatile component is added to control nicotine release, then release consistency is improved, but material composition complexity increases
Solution Approach 1:
The invention changes the vapor pressure parameter of the aerosol generating material by incorporating a volatile component with higher vapor pressure than nicotine. This parameter change creates a competitive volatilization environment that controls nicotine release kinetics. By selecting volatile components with specific vapor pressure characteristics, the system achieves consistent nicotine delivery without requiring complex multi-component formulations or sophisticated delivery mechanisms.
