Aerosol-Forming Article With Covered Heating Layer for Residue Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The issue with existing heat-not-burn products is that the heating body accumulates dirt during use, leading to a burnt flavor and odor, affecting taste consistency due to direct contact with the HNB product.
Innovation Solution
An aerosol-forming article with a heating layer that generates eddy currents in a magnetic field to heat an aerosol-forming substrate, enclosed by a cover layer, preventing direct contact and residue accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the heating body is reused and in direct contact with the HNB product, then the device complexity is reduced and ease of operation is improved, but dirt accumulates on the heating body causing burnt flavor and odor
Solution Approach 1:
The heating system is divided into two separate components: a reusable heating body and a disposable aerosol-forming article. This segmentation allows the heating body to be reused without accumulating dirt, while the disposable article is discarded after use, preventing burnt flavor and odor.
Solution Approach 2:
The aerosol-forming article is designed as a disposable component that is replaced after each use. This eliminates the accumulation of dirt on the heating body, preventing burnt flavor and odor, while the heating body itself can be reused multiple times.
2Power
If the heating body is in direct contact with the HNB product, then heating efficiency is improved, but the heating body becomes hard to clean
Solution Approach 1:
The aerosol-forming article is designed as a disposable component that is replaced after each use. This eliminates the need to clean the heating body, as the disposable article is discarded after use, making the system easy to maintain while maintaining heating efficiency.
Solution Approach 2:
The aerosol-forming substrate is extracted from the heating body and placed in a separate disposable article. This allows the heating body to remain clean and reusable, while the substrate that accumulates residue is easily removed by replacing the entire article.
3Object-generated harmful factors
If the heating layer is isolated from the aerosol-forming substrate, then burnt flavor and odor are prevented, but device complexity increases
Solution Approach 1:
A thin cover layer is used to isolate the heating layer from the aerosol-forming substrate. This simple barrier structure prevents direct contact and accumulation of dirt, preventing burnt flavor and odor without significantly increasing device complexity.
Solution Approach 2:
The aerosol-forming substrate is nested within a housing that includes the heating layer and cover layer. This nested structure provides isolation between the heating layer and substrate while maintaining a compact design that does not significantly increase overall device complexity.

AI summary
An aerosol-forming article includes: an aerosol-forming substrate; a heating layer encircling a concave portion, the aerosol-forming substrate being arranged in the concave portion; and a cover layer covering at least a part of the heating layer and an opening of the concave portion. The aerosol-forming substrate is located between the heating layer and the cover layer. A through hole is provided at a position of the cover layer corresponding to the opening. The heating layer generates eddy currents in a magnetic field to generate heat so as to heat the aerosol-forming substrate to form aerosols.
