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. 11,857,703.

Summary of the Inventive Concept

The present inventive concept adapts the original fragrance delivery system for specific, narrow markets or unique operational environments, such as high-security needs, disaster relief, extreme weather conditions, confined spaces, and high-altitude environments.

Background and Problem Solved

The original fragrance delivery system, as described in the original patent, is limited in its ability to operate effectively in specialized environments. For instance, high-security vehicles require tamper-evident properties, disaster relief shelters need hand-cranked generators, and extreme weather conditions necessitate resistance to moisture and temperature fluctuations. The present inventive concept addresses these limitations by providing specialized fragrance delivery systems tailored to these unique operational environments.

Detailed Description of the Inventive Concept

The new inventive concept comprises a fragrance delivery system with cartridges containing solid elements loaded by adsorption of an olfactory composition and opened by a grid having holes, the cross-section of which is smaller than the cross-section of the solid elements. The solid elements are made of polymer materials with enhanced properties, such as tamper-evident properties for high-security vehicles, resistance to moisture and temperature fluctuations for extreme weather conditions, air purification properties for confined spaces, and oxygen sensitivity for high-altitude environments. Additionally, the system can be powered by hand-cranked generators for use in disaster relief shelters.

Novelty and Inventive Step

The new claims introduce novel and non-obvious features, such as the use of polymer materials with enhanced properties, hand-cranked generators, and adaptations for specific operational environments. These features provide a significant improvement over the original patent and demonstrate an inventive step.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include the use of different polymer materials, varying grid hole sizes, or alternative power sources. Additionally, the system could be adapted for use in other niche environments, such as hospitals, schools, or public transportation.

Potential Commercial Applications and Market

The present inventive concept has significant commercial potential in various industries, including automotive, aerospace, disaster relief, and healthcare. The ability to provide customized fragrance delivery systems for specific operational environments can provide a competitive advantage in these markets.
