Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol provision devices, such as e-cigarettes, often fail to provide consistent delivery and sensorial experience due to aerosol condensation within the heating chamber, affecting the taste and effect of each puff.
Innovation Solution
Incorporating a warming element made of ferritic material between the aerosol generator and the reception region to prevent or reduce aerosol condensation, using a heating mechanism like induction coils or resistive heaters to maintain a temperature range of 60-150°C, and employing a susceptor like aluminum foil to enhance aerosol generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a heating element is used to generate aerosol, then aerosol generation is achieved, but aerosol condensation occurs within the chamber
Solution Approach 1:
The patent introduces a warming element that maintains the chamber temperature within a specific range (60-150°C) to prevent aerosol condensation. By controlling the thermal parameter of the chamber environment, the system ensures aerosol remains in vapor phase and delivers consistently without condensing on chamber walls.
Solution Approach 2:
The warming element acts as an intermediary component between the heating element and the chamber walls. It transfers thermal energy to the chamber walls to maintain their temperature, preventing condensation without directly contacting the aerosol generation process.
2Reliability
If the chamber temperature is increased to prevent condensation, then aerosol delivery consistency improves, but energy consumption increases
Solution Approach 1:
The warming element is strategically positioned to heat only specific regions of the chamber where condensation is most likely to occur. This localized heating approach maintains aerosol delivery consistency in critical areas while minimizing overall energy consumption compared to heating the entire chamber.
Solution Approach 2:
The system applies partial heating through the warming element rather than full heating of the entire chamber. This partial action is sufficient to prevent condensation in the critical aerosol path while consuming less energy than complete chamber heating would require.
