Aerosol-Generating Article with Upstream Aversive Agent
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol-generating articles face challenges in deterring accidental ingestion or handling while maintaining the quality of the aerosol delivery, as aversive agents can contaminate fingers or lips and affect the taste during normal use.
Innovation Solution
The aerosol-generating article is designed with an aversive agent positioned in an upstream section away from the airflow pathway and consumer contact, preventing direct exposure and release into the aerosol.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If an aversive agent is added to deter accidental ingestion, then safety against accidental ingestion is improved, but the risk of contaminating fingers and affecting aerosol taste is worsened
Solution Approach 1:
The aerosol-generating article is divided into distinct sections: an upstream section containing the aversive agent, an aerosol-generating substrate, and a downstream section. This segmentation isolates the aversive agent in the upstream section, preventing it from contaminating the aerosol generated downstream while maintaining its deterrent function against accidental ingestion.
2Object-affected harmful factors
If an aversive agent is placed in the aerosol-generating article, then deterrent effect is improved, but contact with lips during normal use is worsened
Solution Approach 1:
The aversive agent is localized specifically in the upstream section of the aerosol-generating article, which is positioned away from the consumer's lips during normal use. This local placement ensures the aversive agent remains effective for deterrence while minimizing contact with the user's oral mucosa during intended operation.
3Object-generated harmful factors
If the aversive agent is positioned upstream away from airflow, then aerosol quality is improved, but effectiveness in deterring ingestion is worsened
Solution Approach 1:
The upstream section acts as an intermediary zone that contains the aversive agent separately from the aerosol generation pathway. This intermediate positioning allows the aversive agent to serve its deterrent function while being physically separated from the airflow pathway, preventing contamination of the aerosol.
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
This design effectively prevents aversive agent contact during normal use, maintaining aerosol quality and reducing accidental ingestion risks without affecting the intended use experience.
Implementation Method 1
volatile compounds are released from the aerosol-generating substrate by heat transfer from the heat source
Implementation Method 2
heat transfer from a heat source to a physically separate aerosol-generating substrate
Implementation Method 3
As the released compounds cool, they condense to form an aerosol
