Aerosol Generation Device with Segmented Flavor Cartridge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic cigarettes fail to deliver the same quality of experience as traditional tobacco-based smoking articles due to chemical and pharmacological incompatibilities in composite aerosol forming liquid solutions, leading to particulate precipitation, fouling of heating elements, and chemical degradation, which compromises the organoleptic performance of the aerosol vapor.
Innovation Solution
A two-step process for generating a functionalized aerosol vapor that involves forming an aerosol from a non-flavored formulation and then subjecting it to a matrix for transferring organoleptic properties like taste, fragrance, and nicotine, using a separate functional composition with vapor pressure modifiers and encapsulated components to enhance the delivery of these properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a composite aerosol forming liquid solution is used to generate aerosol-based vapor, then the vapor can be produced, but chemical and pharmacological incompatibilities occur leading to particulate precipitation, fouling of heating elements, and chemical degradation
Solution Approach 1:
The invention divides the composite aerosol forming liquid into separate components: an aerosol base liquid and separate flavor/nicotine cartridges. This segmentation prevents direct contact between incompatible substances, eliminating chemical degradation and particulate precipitation while maintaining reliable aerosol vapor delivery.
Solution Approach 2:
The invention extracts the flavor and nicotine components from the aerosol base liquid into separate cartridges. This extraction removes the source of chemical incompatibilities and fouling, allowing the aerosol base to remain chemically stable while still delivering the desired organoleptic properties through the separate cartridge components.
2Quantity of substance
If a composite aerosol forming liquid solution is used, then aerosol vapor can be generated, but fouling of the aerosol heating element occurs
Solution Approach 1:
The invention extracts flavor and nicotine components into separate cartridges, removing them from the aerosol base liquid that contacts the heating element. This prevents fouling of the heating element while maintaining aerosol vapor generation capability through the cartridge-based delivery system.
3Reliability
If separate aerosol base liquid and flavor/nicotine cartridges are used, then chemical stability is improved, but device complexity increases
Solution Approach 1:
The invention merges the aerosol base liquid reservoir with the flavor/nicotine cartridges into an integrated device system. While the components are chemically separated for stability, they are mechanically combined into a unified device that functions as a cohesive whole, managing complexity through integrated design rather than separate systems.
4Ease of operation
If flavor and nicotine are delivered through the aerosol base liquid, then organoleptic properties are achieved, but chemical degradation and particulate precipitation occur
Solution Approach 1:
The invention segments the organoleptic delivery components (flavor and nicotine) into separate cartridges from the aerosol base liquid. This allows the aerosol base to maintain chemical stability while the cartridge components deliver the desired organoleptic properties through controlled release mechanisms, preventing chemical degradation and particulate precipitation.
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
This approach improves the consistency and quality of the aerosol vapor by separating aerosol formation from flavoring, reducing degradation, and allowing for flexible flavor changes without tank cleaning, resulting in a more authentic smoking experience.
Implementation Method 1
a heater operable to heat the liquid material to a temperature sufficient to vaporize the liquid material and form an aerosol
Implementation Method 2
a wick in communication with the liquid material and in communication with the heater such that the wick delivers the liquid material to the heater
