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 described an aerosol-generating system for use in electronic cigarettes. However, the limitations of this technology were confined to a specific industry. This new invention addresses the problem of underutilization of aerosol-generating systems by expanding their application to diverse industries, thereby increasing their value and potential impact.

Novelty and Inventive Step

The new invention introduces novel applications and use cases for aerosol-generating systems, which were not originally considered in the original patent. The inventive step lies in the recognition of the potential of aerosol-generating systems to address diverse industry-specific problems and the adaptation of the core technology to achieve this.

Alternative Embodiments and Variations

Alternative embodiments may include variations in susceptor element design, substrate materials, and system configurations to optimize performance for specific industries. For instance, the susceptor element could be modified to accommodate different substrate geometries or the system could be scaled up or down depending on the application.

Potential Commercial Applications and Market

The invention has significant commercial potential in various industries, including water treatment, air quality control, fragrance and flavoring, pest management, and surface sanitization. The target market includes companies operating in these industries, as well as startups and research institutions exploring innovative solutions.
