Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid-type electronic cigarettes face limitations due to the continuous sublimation of nicotine, leading to component loss and volatility issues.
Innovation Solution
A non-heating type smoking article featuring a semi-solid medium part containing nicotine and an aerosol-generating material, formed through a semi-solidifying agent, which stabilizes the nicotine in a semi-solid phase, preventing sublimation and enhancing nicotine migration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If nicotine is used in liquid form in conventional electronic cigarettes, then nicotine delivery is achieved through sublimation and vaporization, but components are lost due to continuous sublimation
Solution Approach 1:
The patent changes the physical state of nicotine from liquid to semi-solid phase by incorporating it into a semi-solid medium containing gelatin, starch, or other semi-solidifying agents. This parameter change prevents continuous sublimation while maintaining nicotine delivery capability through controlled release mechanisms.
Solution Approach 2:
The invention creates a composite material system where nicotine is combined with semi-solidifying agents (gelatin, starch, polysaccharides) to form a semi-solid medium. This composite structure stabilizes nicotine and prevents component loss while enabling controlled migration and delivery.
2Ease of operation
If nicotine is used in free base form for self-vaporization, then aerosol generation is achieved, but stability is reduced due to continuous sublimation
Solution Approach 1:
The patent changes nicotine from volatile free base form to a stabilized semi-solid phase embedded in a matrix of semi-solidifying agents. This transformation maintains aerosol generation capability while significantly improving compositional stability by eliminating continuous sublimation.
Solution Approach 2:
The semi-solid medium acts as a disposable carrier that stabilizes nicotine during storage and controlled release during use. The semi-solidifying agents provide a stable matrix that maintains nicotine integrity until activation, solving the stability issue without requiring complex stabilization systems.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The semi-solid medium part effectively stabilizes nicotine, reducing sublimation and allowing for efficient nicotine migration, while maintaining a rich taste expression through pH control and optimal viscosity, ensuring consistent nicotine delivery.
Implementation Method 1
nicotine in the form of a free base may have a possibility of losing components due to the nature of continuously sublimating
Implementation Method 2
capable of effectively migrating nicotine even with a non-heating type by applying a medium part that is changed to a semi-solid state
Implementation Method 3
a semi-solid phase which contains nicotine and an aerosol-generating material
