Tobacco Solution Vaporization at Low Temperatures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current e-cigarettes vaporize tobacco constituents at temperatures above 200 degrees C, requiring high power and potentially breaking molecules, whereas there is a need for a safer, more efficient method that vaporizes at temperatures under 200 degrees C, ideally at or below 100 degrees C, to minimize power consumption and enhance deeper lung penetration and absorption of tobacco constituents.
Innovation Solution
A method and device using a first solution comprising water, alcohol, and propylene glycol to extract nicotine and monoamine oxidase inhibitors from tobacco, followed by vaporization using a piezoelectric element or low temperature vaporizer, potentially substituting propylene glycol with polysorbate compounds to achieve vaporization at 100 degrees C or lower, allowing for deeper lung penetration with smaller molecules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If high temperature vaporization (>200°C) is used, then vaporization of tobacco constituents is achieved, but power consumption increases and molecular degradation occurs
Solution Approach 1:
The patent changes the physical-chemical parameters of the vaporization system by introducing a eutectic mixture with a defined composition (62-68% propylene glycol, 30-35% glycerin, 2-5% water). This composition change creates a eutectic point at 100°C or lower, fundamentally altering the vaporization temperature parameter from conventional >200°C to ≤100°C, thereby resolving the contradiction between achieving vaporization and minimizing power consumption
Solution Approach 2:
The patent employs a composite solution system combining propylene glycol, glycerin, and water in specific proportions to form a eutectic mixture. This composite material approach leverages the synergistic effects of the three components to achieve a lowered eutectic point, enabling low-temperature vaporization while maintaining effective delivery of tobacco constituents
2Temperature
If high temperature vaporization (>200°C) is used, then vaporization is achieved, but molecular integrity is compromised
Solution Approach 1:
By changing the vaporization temperature parameter from conventional high temperatures (>200°C) to low temperatures (≤100°C) through the eutectic mixture, the patent prevents thermal degradation of tobacco constituents. The lowered temperature parameter preserves molecular integrity while still achieving effective vaporization and delivery of nicotine and other tobacco components
Solution Approach 2:
The patent replaces the conventional thermal field approach (high-temperature heating) with an alternative mechanism based on the eutectic phase transition of the mixed solvent system. This substitution allows vaporization to occur at temperatures that do not compromise the chemical stability and molecular integrity of the tobacco constituents
3Quantity of substance
If larger molecules are used in the solution, then vaporization is achieved, but lung penetration depth is reduced
Solution Approach 1:
The patent optimizes the molecular parameter of the solution components by selecting propylene glycol and glycerin, which have relatively small molecular sizes. This parameter optimization enables deeper penetration into the lung tissue while maintaining effective vaporization, resolving the contradiction between solution composition and penetration depth
