Exposed Aerosol Substrate Structure to Eliminate Heating Odors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol generating articles with substrates wrapped in packaging materials experience a peculiar smell when heated, affecting user experience due to the interaction between the wrapper and substrate.
Innovation Solution
The aerosol generating article features an integral aerosol generating substrate with a first air flow channel, partially exposed and without additional wrappers, ensuring direct exposure during use, thereby preventing the heating of packaging materials and the associated smell.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wrapper such as packaging paper or packaging shell is disposed on the aerosol generating substrate, then the substrate is protected from loosening, but a peculiar smell is generated when heated
Solution Approach 1:
The patent removes the wrapper (packaging paper or packaging shell) from the aerosol generating article structure, exposing the aerosol generating substrate directly. This extraction eliminates the source of the peculiar smell that occurs when the wrapper is heated, while the substrate maintains its structural integrity through its own integral design with air flow channels.
2Productivity
If the aerosol generating substrate is entirely exposed, then heating efficiency is improved and smell is eliminated, but structural support is reduced
Solution Approach 1:
The aerosol generating substrate is designed as an integral structure with segmented air flow channels incorporated within it. This segmentation allows the substrate to maintain structural integrity while enabling efficient air flow and heat distribution throughout the exposed substrate, achieving both structural support and heating efficiency.
Solution Approach 2:
The patent employs a thin film or membrane structure for the aerosol generating substrate that can be entirely exposed. This thin film structure provides sufficient structural support while allowing direct heating and air flow, eliminating the need for additional wrapping materials that would interfere with heating efficiency.

AI summary
Embodiments of this application provide an aerosol generating article and an aerosol generating article assembly. The aerosol generating article includes at least an aerosol generating substrate, the aerosol generating substrate is an integral structure including a first air flow channel, and the aerosol generating substrate is at least partially exposed. In the embodiment of this application, during use of the aerosol generating article, an exposed part of the aerosol generating substrate is not covered by another wrapper such as packaging paper or a packaging shell. Therefore, a case in which a peculiar smell is generated because the wrapper such as the packaging paper and the packaging shell is heated does not occur in the aerosol generating article, thereby improving use experience of a user.
