Filter Rod Capsule for Consistent Nicotine Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Nicotine delivery in electronic tobacco hybrid devices is inconsistent and volatile due to pH treatment, leading to reduced nicotine release per puff and unintended nicotine loss.
Innovation Solution
A filter rod consumable with aerosolizable material containing nicotine and capsules of basic solution, where the basic solution is released upon use to adjust the pH and liberate nicotine, controlling its release and minimizing volatility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If pH treatment is applied to aerosolizable material containing nicotine, then nicotine release is enhanced, but nicotine delivery becomes inconsistent and volatile with unintended nicotine loss
Solution Approach 1:
The filter rod is divided into distinct functional zones: a first section containing aerosolizable material with nicotine, and a second section containing basic solution. This segmentation prevents premature contact between nicotine and base, ensuring consistent nicotine delivery by controlling the timing and location of pH treatment.
Solution Approach 2:
The basic solution is extracted from the aerosolizable material section and placed in a separate second section of the filter rod. This extraction eliminates the harmful effect of premature pH treatment while preserving the beneficial effect of controlled nicotine release when the user inhales.
2Quantity of substance
If basic solution is pre-mixed with aerosolizable material, then nicotine is liberated, but volatility increases leading to unintended nicotine loss
Solution Approach 1:
The filter rod is prepared in advance with separate compartments for aerosolizable material and basic solution, but the chemical reaction is delayed until the moment of use when the user inhales. This preliminary preparation without premature reaction prevents nicotine volatility and loss while ensuring ready availability when needed.
Solution Approach 2:
The filter rod structure acts as an intermediary that physically separates the aerosolizable material from the basic solution during storage and transport, preventing premature reaction. During use, the inhalation flow serves as the intermediary that brings these components into contact, enabling controlled nicotine liberation without loss.
3Ease of operation
If ammonia is released during nicotine liberation, then organoleptic properties are enhanced, but uncontrolled ammonia release degrades quality
Solution Approach 1:
The filter rod is designed with different local qualities in different sections: the first section contains aerosolizable material optimized for nicotine delivery, while the second section contains basic solution positioned to control ammonia release. This local differentiation ensures ammonia is released in a controlled manner to enhance organoleptic properties without degrading quality.
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 provides consistent nicotine delivery per puff by converting nicotine to a volatile form only before use, reducing unintended nicotine losses and enhancing organoleptic properties by controlling ammonia release.
Implementation Method 1
the basic solution can be released from the capsule to contact the aerosolizable material upon actuation by a user
Implementation Method 2
converting nicotine to a volatile form only before use
