Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aerosol generating articles experience slow generation of aerosol due to insufficient heat transfer to the tobacco medium, leading to prolonged wait times for aerosol delivery.
Innovation Solution
Incorporation of heat conductors within and around the tobacco medium to enhance heat transfer, including first, second, and third heat conductors to improve thermal conductivity and maintain high temperatures, along with an airflow path design to maximize heat absorption and aerosol fluidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a heat source is used to heat the tobacco medium, then aerosol generation is enabled, but the heat transfer is insufficient causing slow aerosol generation
Solution Approach 1:
The patent introduces a heat conductor as an intermediary substance between the heat source and the tobacco medium. This heat conductor has high thermal conductivity and acts as a mediator to efficiently transfer heat from the heat source to the tobacco medium, resolving the insufficient heat transfer issue and enabling faster aerosol generation without energy loss.
2Productivity
If heat is applied to generate aerosol, then aerosol is produced, but the tobacco medium breaks easily under external force
Solution Approach 1:
The patent applies local quality by introducing a heat conductor only in the specific region where heat transfer is needed (between the heat source and tobacco medium), rather than changing the entire tobacco medium structure. This localized approach maintains aerosol generation capability while preserving the overall structural integrity of the tobacco medium.
3Loss of energy
If multiple heat conductors are added to improve heat transfer, then heat transfer efficiency increases, but device complexity increases
Solution Approach 1:
The patent merges the heat conduction function with the existing tobacco medium structure by incorporating the heat conductor into the tobacco medium matrix. This integration approach combines multiple functions (structural support and heat conduction) into a single unified structure, improving heat transfer efficiency without significantly increasing device complexity.
