This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,856,993.

Background and Problem Solved

The original aerosol-generating system, as described in the original patent, has limitations in terms of heat loss, electromagnetic interference, and thermal stability. The new invention addresses these limitations by introducing novel components and methods that improve the overall efficiency and safety of the system.

Novelty and Inventive Step

The new claims introduce novel designs and materials that are not obvious from the original patent. The combination of the thermal insulation layer, spiral inductor coil design, novel aerosol-forming substrate, power management system, and 3D printing technique provides a non-obvious solution to the limitations of the original invention.

Alternative Embodiments and Variations

Alternative embodiments of the invention could include the use of different materials for the thermal insulation layer, varying geometries for the susceptor element, or alternative power management systems. Additionally, the invention could be adapted for use in different applications, such as in medical devices or industrial processes.

Potential Commercial Applications and Market

The enhanced aerosol-generating system has significant commercial potential in the e-cigarette and vaping industries, where efficiency, safety, and performance are critical factors. The invention could also be applied in other industries, such as medical devices, industrial processes, and consumer products, where aerosol generation is required.
