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 aerosol-generating system patent (WO 2019/234245 A1) has limitations in cartridge design, which can lead to inefficient heat transfer, leakage, and inconsistent aerosol generation. The present invention addresses these issues by introducing a new cartridge design with a non-circular cross-section body, sealing protrusions, and optimized susceptor elements.

Novelty and Inventive Step

The new claims introduce a novel cartridge design with a non-circular cross-section body, sealing protrusions, and optimized susceptor elements, which provide improved efficiency, safety, and user experience. The inventive step lies in the combination of these features, which address the limitations of the original patent and provide a significant improvement in aerosol generation.

Alternative Embodiments and Variations

Alternative embodiments of the invention may include cartridges with different cross-sectional shapes, such as triangular or hexagonal, and varying susceptor element configurations. Additionally, the aerosol generating device could be modified to accommodate different heater element designs or materials.

Potential Commercial Applications and Market

The enhanced aerosol-generating system has significant commercial potential in the e-vapor and heat-not-burn industries, offering improved products with enhanced user experience, safety, and efficiency. The target market includes manufacturers of e-vapor and heat-not-burn products, as well as consumers seeking advanced alternatives to traditional tobacco products.
