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. 11,857,717.

Summary of the Inventive Concept

An improved aerosol generating system that integrates temperature sensors, pressure sensors, and novel air flow channels to enhance aerosol delivery, efficiency, and safety, while providing users with a more intuitive and informative experience.

Background and Problem Solved

The original patent described a cartridge for use in an aerosol-generating device, but it had limitations in terms of aerosol delivery efficiency, safety, and user experience. The new inventive concept addresses these limitations by introducing integrated sensors and controls, novel air flow channels, and an improved user interface.

Detailed Description of the Inventive Concept

The enhanced aerosol generating system comprises a cartridge with an integrated temperature sensor to monitor and control the heating of nicotine and acid sources. The system also features a novel spiral-shaped air flow channel that increases the interaction between the air flow and the heated nicotine and acid sources. Additionally, the system includes an aerosol-generating device with an improved user interface, comprising a touchscreen display to adjust the power level and temperature of the inductor coil, and a real-time display of the generated aerosol's nicotine content. Furthermore, the system incorporates a pressure sensor to detect and prevent over-pressurization of the aerosol-generating device.

Novelty and Inventive Step

The new inventive concept introduces novel and non-obvious features, such as the integration of temperature sensors, pressure sensors, and novel air flow channels, which significantly improve aerosol delivery, efficiency, and safety. The improved user interface and real-time display of nicotine content also provide a distinct advantage over the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include different sensor configurations, such as using infrared sensors or thermocouples instead of temperature sensors. The novel air flow channel could also be modified to have different shapes or geometries. Additionally, the user interface could be adapted for different devices or form factors.

Potential Commercial Applications and Market

The enhanced aerosol generating system has significant commercial potential in the e-cigarette and vaping industries, where there is a growing demand for safer and more efficient products. The system's improved user experience and real-time nicotine content display could also appeal to health-conscious consumers.
