Aerosol Generation Device Chamber Ventilation Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Heat-not-burn aerosol generation devices face issues with aerosol overheating, leading to an unpleasant inhalation experience due to inadequate cooling, as perforations on consumable articles can be covered by users' lips and are not optimally positioned for maximum cooling effect.
Innovation Solution
An aerosol generation device with a chamber featuring through holes in its side walls to enhance ventilation and cooling, allowing air to mix with the aerosol and ventilate the consumable article, along with a heater positioned on the outer wall for efficient heating and a collar for easy article insertion and air entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If perforations are provided on the consumable article for cooling, then aerosol cooling effect is improved, but the perforations may be covered by user's lips reducing air flow
Solution Approach 1:
The invention extracts the cooling function from the consumable article's surface perforations and relocates it to the chamber structure. The chamber now provides cooling air flow paths and ventilation holes independent of the article's surface features, ensuring cooling functionality is not compromised by user lip coverage of article perforations.
Solution Approach 2:
The chamber acts as an intermediary structure between the heating element and the user's mouthpiece. It introduces a dedicated cooling air flow path that bypasses the need for user-dependent surface perforations, mediating the cooling function through structured air channels within the chamber itself.
2Ease of operation
If perforations are positioned outside the aerosol generation device, then air circulation is improved, but the position is limited and not optimal for maximum cooling
Solution Approach 1:
The invention transitions from relying solely on external surface perforations to utilizing the three-dimensional chamber structure. By incorporating cooling air flow paths and ventilation holes within the chamber's volume and structure, the system exploits spatial dimensions inside the device to optimize cooling efficiency beyond what surface-level perforations can achieve.
3Productivity
If heater is positioned to heat aerosol precursor material, then aerosol generation speed is improved, but aerosol may become too hot for comfortable inhalation
Solution Approach 1:
The invention segments the thermal processing into distinct zones: a heating zone for rapid aerosol generation and a separate cooling zone within the chamber for temperature reduction. This spatial segmentation allows simultaneous optimization of both aerosol generation speed and inhalation comfort temperature.
Solution Approach 2:
The chamber is pre-configured with cooling air flow paths and ventilation holes that prepare cool air in advance. When aerosol is generated, the cooling air is already positioned to immediately mix with and cool the hot aerosol, providing preliminary cooling action before the aerosol reaches the user.
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 solution effectively cools the aerosol, providing a better user experience by ensuring efficient ventilation and heating, reducing aerosol temperature and improving air circulation around the consumable article.
Implementation Method 1
a heater arranged about or formed of an outer wall of the chamber and configured to heat the aerosol precursor material of the consumable article
Implementation Method 2
ventilation air may more easily mix with the generated aerosol and ventilate a consumable article, therefore increasing the cooling effect provided by the ventilation air
