Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multiple use aerosol-generating systems for nicotine salt particles face challenges in retaining sufficient nicotine and volatile delivery enhancing compounds during storage, leading to degradation and inefficient aerosol generation.
Innovation Solution
A movable housing system with separate compartments for nicotine and volatile delivery enhancing compounds, allowing fluid communication only during use, prevents degradation and ensures consistent aerosol production by isolating the reactants when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the aerosol-generating system is designed for multiple use, then the duration of action is extended, but the nicotine and volatile delivery enhancing compound degrade during storage
Solution Approach 1:
The housing is divided into a first portion containing the nicotine source and a second portion containing the volatile delivery enhancing compound source. These segmented compartments prevent direct contact and degradation between the two reactants during storage, while allowing them to mix only when the housing is opened for use, thereby maintaining reliability over extended duration.
Solution Approach 2:
The housing is designed to be movable between a closed position (during storage) and an open position (during use). This dynamic configuration allows the system to transition from a protected state that prevents degradation to an active state that enables aerosol generation, resolving the contradiction between long-term storage stability and functional reliability.
2Reliability
If the housing is kept closed during storage, then the nicotine and volatile compound are retained without degradation, but the aerosol cannot be generated
Solution Approach 1:
The movable housing design allows the user to easily transition between closed and open positions. The simplicity of this mechanical operation enables easy access to the reactants when needed while maintaining protection during storage, balancing operational ease with reliability.
Solution Approach 2:
The reactants are extracted into separate compartments within the housing. This segmentation allows the system to maintain reliability during closed storage while enabling easy operation during use, as the user simply needs to open the housing to access both reactants simultaneously for aerosol generation.
3Productivity
If the nicotine source and volatile delivery enhancing compound source are in fluid communication during storage, then aerosol can be generated immediately, but the reactants degrade through oxidation and hydrolysis
Solution Approach 1:
The housing is divided into a first portion containing the nicotine source and a second portion containing the volatile delivery enhancing compound source. These segmented compartments prevent direct contact and degradation between the two reactants during storage, while allowing them to mix only when the housing is opened for use, thereby maintaining reliability over extended duration.
Solution Approach 2:
The closed housing creates a protected environment that isolates the reactants from external factors such as oxygen and moisture that cause oxidation and hydrolysis. This inert-like environment preserves the reactants during storage while allowing controlled interaction when needed.
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 system effectively retains nicotine and volatile compounds, preventing degradation and ensuring consistent aerosol generation with each use, improving the efficiency and longevity of the aerosol-generating device.
Implementation Method 1
The first portion of the housing and the second portion of the housing are movable relative to one another between an open position in which the nicotine source and the volatile delivery enhancing compound source are both in fluid communication with an airflow pathway through the housing between the air inlet and the air outlet and a closed position in which the air flow pathway through the housing between the air inlet and the air outlet is obstructed
Implementation Method 2
The mouthpiece comprises a liquid storage portion, a capillary wick having a first end that extends into the liquid storage portion for contact with liquid therein, and a heating element for heating a second end of the capillary wick. In use, liquid is transferred from the liquid storage portion towards the heating element by capillary action in the wick. Liquid at the second end of the wick is vaporised by the heating element.
Implementation Method 3
liquid is transferred from the liquid storage portion towards the heating element by capillary action in the wick
Implementation Method 4
The nicotine and volatile delivery enhancing compound are reacted with one another in the gas phase to form an aerosol of nicotine salt particles that is inhaled by the user

AI summary
An aerosol-generating system is provided, including a housing having a first portion and a second portion. The housing includes an air inlet; a nicotine source; a volatile delivery enhancing compound source; and an air outlet. The first portion of the housing and the second portion of the housing are movable relative to one another between an open position and a closed position. In the open position, the air inlet and the air outlet are unobstructed and the nicotine source and the volatile delivery enhancing compound source are both in fluid communication with an airflow pathway through the housing between the air inlet and the air outlet. In the closed position, either the air inlet is obstructed or the nicotine source and the volatile delivery enhancing compound source are both not in fluid communication with an airflow pathway through the housing between the air inlet and the air outlet or both.
