Solution Overview
Problem
Existing non-combustible aerosol delivery systems lack effective control over aerosol particle size and total aerosol production, which is crucial for simulating a specific smoking experience in e-cigarettes and similar products.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If uniform aerosolizable material delivery is used across the aerosol generating component, then manufacturing is simpler, but control over aerosol particle size and total aerosol production is poor
Solution Approach 1:
The patent applies local quality by creating regions of different material delivery rates across the aerosol generating component surface. The feed apertures are strategically positioned and sized to deliver aerosolizable material preferentially to specific regions, creating local variations in material concentration and vaporization rate that enable controlled aerosol particle size and distribution
2Ease of operation
If aerosolizable material is delivered uniformly across the aerosol generating component, then the system is easier to operate, but aerosol characteristics cannot be controlled
Solution Approach 1:
The patent segments the material delivery system by providing multiple discrete feed apertures at different locations on the aerosol generating component. Each aperture can be independently designed with specific dimensions and positioning to control material flow to different regions, enabling precise aerosol characteristic control while maintaining operational simplicity
3Ease of manufacture
If the aerosol generating component has uniform properties, then manufacturing is easier, but sensorial experience cannot be optimized
Solution Approach 1:
The patent implements local quality by designing the aerosol generating component with spatially varying properties - different regions have different feed aperture configurations, material delivery rates, and vaporization characteristics. This allows optimization of sensorial experience through controlled variations in aerosol particle size and distribution while using standard manufacturing techniques for each local region
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 enhances control over aerosol characteristics, improving the sensorial experience by adjusting particle size and total aerosol delivery, ensuring efficient and consistent vaporization.
Implementation Method 1
aerosolizable material is preferentially delivered to portions of the aerosol generating component configured to vaporize the aerosolizable material
Implementation Method 2
the periphery of the aerosol generating component is coupled to one or more feed apertures such that liquid aerosolizable material may be fed directly to the majority of the periphery
