Dual Substrate Aerosol Device for Consistent Atomization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional aerosol-generating articles face challenges in maintaining a constant amount of aerosol generation due to variations in heat transfer and absorption of ingredients, particularly glycerin, leading to inconsistent atomization throughout smoking.
Innovation Solution
Incorporating a second aerosol-generating substrate with an absorber impregnated with a liquid aerosol-generating composition, positioned alongside a nicotine-containing first aerosol-generating substrate, and simultaneously heating both substrates to maintain consistent aerosol production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single aerosol-generating substrate is used, then the device structure is simple, but the aerosol generation amount is not constant throughout smoking
Solution Approach 1:
The patent divides the aerosol-generating substrate into two separate substrates: a first aerosol-generating substrate containing nicotine and a second aerosol-generating substrate containing glycerin. This segmentation allows each substrate to be optimized for its specific function and ensures consistent aerosol generation throughout the smoking process by maintaining separate but coordinated aerosol production from both substrates.
2Quantity of substance
If glycerin is added to a single substrate, then atomization is enhanced, but the atomization amount varies during smoking
Solution Approach 1:
The patent separates glycerin from the nicotine-containing substrate and places it in a dedicated second aerosol-generating substrate. This ensures that glycerin is available throughout the entire smoking process to maintain consistent atomization, while the nicotine substrate can be optimized for nicotine delivery. The two substrates work together to provide stable atomization from start to finish.
3Ease of manufacture
If heat transfer variations occur in the substrate, then manufacturing is easier, but aerosol generation becomes inconsistent
Solution Approach 1:
By dividing the substrate into two separate aerosol-generating substrates, the patent allows each substrate to be manufactured with simpler, more uniform properties that are easier to produce consistently. The segmentation reduces the complexity of achieving uniform heat transfer across a single complex substrate, while the coordinated operation of both substrates ensures consistent overall aerosol generation.
