Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aerosol generating devices that heat aerosol generating materials face limitations in use due to the generation of aerosol, restricting their application based on location or environment, and there is a need for a system that allows both smoking with smoke and smokeless smoking.
Innovation Solution
An aerosol generating system comprising an aerosol generating article with a tobacco medium portion including a tobacco material and a pH adjuster, and an aerosol generator, paired with a device that has a heater powered by a battery and controlled by a controller to selectively operate in smokeless or smoke modes, allowing user input to determine the mode of operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the heater heats the aerosol generating material to generate aerosol, then the user experience of smoking is improved, but the device becomes restricted in use based on location or environment
Solution Approach 1:
The system dynamically switches between smoke mode and smokeless mode based on user input, allowing the heating parameters and aerosol generation to be adjusted in real-time. This enables the device to adapt to different usage environments while maintaining user convenience.
Solution Approach 2:
The controller changes the heating parameters of the heater to regulate whether aerosol is generated or not. By adjusting temperature and heating duration parameters, the system can operate in smoke mode for traditional smoking experience or smokeless mode for restricted environments, thus resolving the contradiction between user convenience and environmental adaptability.
2Adaptability or versatility
If the heater operates in smokeless mode without generating aerosol, then usage restrictions are eliminated, but nicotine release may be insufficient
Solution Approach 1:
The system uses pH adjuster to modify the chemical parameters of the tobacco material, which enhances nicotine release efficiency at lower temperatures. This allows the device to operate in smokeless mode with adequate nicotine delivery without requiring high-temperature aerosol generation, thus maintaining environmental flexibility while ensuring sufficient nicotine release.
Solution Approach 2:
The tobacco material is combined with pH adjuster to create a composite material that optimizes nicotine release properties. This composite formulation enables effective nicotine delivery in both smoke and smokeless modes, resolving the contradiction between usage flexibility and nicotine quantity.
3Quantity of substance
If the heater operates in smoke mode to generate aerosol, then adequate nicotine release is achieved, but usage is restricted by location or environment
Solution Approach 1:
The system provides dynamic mode switching between smoke and smokeless operation, allowing users to select the appropriate mode based on environmental constraints. The controller adjusts heating parameters in real-time to maintain adequate nicotine release in smoke mode while enabling smokeless operation in restricted environments, thus resolving the contradiction between nicotine quantity and usage flexibility.
4Adaptability or versatility
If the system regulates temperature range to prevent aerosol generation, then usage flexibility is improved, but the complexity of controlling power supply increases
Solution Approach 1:
The controller regulates the heating parameters (temperature, power, duration) of the heater to control aerosol generation. By implementing mode-specific parameter sets (smoke mode parameters vs. smokeless mode parameters), the system achieves usage flexibility while keeping the control logic manageable through predefined parameter configurations rather than complex real-time calculations.
