Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aerosol generating devices face challenges in optimizing aerosol characteristics and maintaining structural integrity of the aerosol generating articles, leading to potential airflow obstructions and reduced delivery efficiency during use.
Innovation Solution
The aerosol generating article comprises a plurality of aerosol generating strips and elongate support elements arranged alternately, wrapped with a non-electrically conductive and non-magnetically permeable wrapping member to form a planar structure, which enhances structural rigidity, minimizes deformation, and creates an airflow channel for optimal aerosol delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If aerosol generating strips are arranged intermittently to optimize aerosol characteristics, then aerosol delivery is improved, but structural integrity and resistance to deformation deteriorate
Solution Approach 1:
The aerosol generating substrate is segmented into multiple intermittent strips arranged in parallel, allowing each strip to function independently for optimized aerosol generation while the collective arrangement maintains structural balance
Solution Approach 2:
Elongate support elements are introduced as intermediary components positioned between and alongside the aerosol generating strips, providing mechanical support and preventing deformation without interfering with the aerosol generation function of the strips
2Strength
If support elements are added to maintain structural rigidity, then structural integrity is improved, but device complexity increases
Solution Approach 1:
A wrapping member in the form of a thin film or shell is used to encapsulate the entire assembly of aerosol generating strips and support elements, providing structural consolidation and rigidity through a single external layer rather than multiple internal components
Solution Approach 2:
The support elements and aerosol generating strips are combined into a single integrated assembly that is then wrapped together, merging the structural support function and the aerosol generation function into one unified article structure
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 configuration ensures maximum aerosol delivery with optimal characteristics by maintaining structural integrity and preventing airflow obstructions, while the wrapping member facilitates efficient vapor condensation and reduces residue buildup in the device.
Implementation Method 1
heating the aerosol generating substrate, without burning the aerosol generating substrate, to volatise at least one component of the aerosol generating substrate and thereby generate a heated vapour which cools and condenses to form an aerosol
Implementation Method 2
generate a heated vapour which cools and condenses to form an aerosol
