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. 11,856,992.

Background and Problem Solved

The original patent, 'Aerosol-generating system, aerosol forming device and a cartridge therefor', disclosed a cartridge with a nicotine source and a lactic acid source. However, this design had limitations in terms of heat transfer, aerosol consistency, and maintenance. The present invention addresses these limitations by introducing a novel susceptor coil design, modular cartridge architecture, and advanced heating protocols.

Novelty and Inventive Step

The novel susceptor coil design, modular cartridge architecture, and advanced heating protocols introduced in the present invention provide a significant improvement over the original patent, offering enhanced aerosol formation, improved flavor profiles, and increased efficiency. These features are new and non-obvious compared to the original patent, demonstrating a clear inventive step.

Alternative Embodiments and Variations

Alternative embodiments of the invention could include variations of the susceptor coil design, such as a helical or zigzag pattern, or the use of different materials for the susceptor element. Additionally, the modular cartridge architecture could be adapted for use with different types of aerosol-forming substrates or flavor profiles.

Potential Commercial Applications and Market

The enhanced aerosol-generating system has significant commercial potential in the e-vapor industry, offering improved performance, efficiency, and customization options for consumers. The modular design and advanced heating protocols could also be applied to other industries, such as pharmaceuticals or cosmetics, where controlled aerosol generation is required.
