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 patent disclosed an aerosol-generating system with a fluid permeable susceptor element. However, the system suffered from thermal losses and inefficient heating, leading to reduced aerosol production and potential safety risks. The new invention addresses these limitations by introducing improved thermal management features, enhancing the overall performance and safety of the system.

Novelty and Inventive Step

The new claims introduce novel features that improve the thermal management of the aerosol-generating system, resulting in increased heating efficiency and improved safety. The combination of a spiral geometry susceptor element, thermal insulation layers, and high-frequency oscillating currents provides a non-obvious solution to the limitations of the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the invention could include varying the spiral geometry of the susceptor element, using different thermal insulation materials, or implementing additional safety features, such as automatic shut-off in case of overheating. Variations could also include integrating the temperature monitoring mechanism into the cartridge or using alternative heating sources.

Potential Commercial Applications and Market

The enhanced aerosol-generating system has significant commercial potential in the e-cigarette and vaping industries, where improved performance and safety are highly valued. The invention could also be applied in other industries, such as pharmaceuticals or cosmetics, where aerosol generation is a critical process.
