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. 11,857,138.

Summary of the Inventive Concept

An improved surface cleaning device with advanced odor management capabilities, providing customizable fragrance release rates, intelligent odor prediction, and adaptive fragrance cartridge switching for enhanced cleaning experiences.

Background and Problem Solved

The original patent, 'Surface cleaning device with odor management,' had limitations in terms of providing optimal fragrance release rates for varying surface types and cleaning modes. The new inventive concept addresses these limitations by introducing advanced odor management features, ensuring a more efficient and effective cleaning experience.

Detailed Description of the Inventive Concept

The advanced odor management system comprises an odor control assembly with a variable fragrance output control, which can be adjusted via a user interface to customize fragrance release rates based on surface type and cleaning mode. The system also utilizes machine learning algorithms to predict optimal fragrance release rates based on user behavior, surface type, and cleaning mode. Additionally, the system includes multiple fragrance cartridges with different fragrance types, which can be automatically switched between based on surface type and cleaning mode. Furthermore, the system features a self-cleaning mechanism that utilizes gentle air flow to remove accumulated fragrance particles and debris from the fragrance air path, ensuring consistent fragrance release rates over time.

Novelty and Inventive Step

The new inventive concept introduces the following novel features: (1) customizable fragrance release rates via a user interface, (2) intelligent odor prediction using machine learning algorithms, (3) adaptive fragrance cartridge switching, and (4) a self-cleaning mechanism for the fragrance air path. These features are not present in the original patent and provide a significant improvement over the existing technology.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include: (1) integrating the advanced odor management system with other cleaning device features, such as suction control or brush roll speed adjustment, (2) using different types of sensors to detect surface type and cleaning mode, (3) incorporating additional fragrance cartridges with unique scents or properties, or (4) developing a mobile application to remotely control and customize the odor management system.

Potential Commercial Applications and Market

The advanced odor management system has significant commercial potential in the cleaning device industry, particularly in the residential and commercial cleaning markets. The system's ability to provide customizable and efficient fragrance release rates can enhance the overall cleaning experience, leading to increased customer satisfaction and loyalty. Additionally, the system's advanced features can differentiate cleaning device manufacturers in a competitive market and provide a unique selling proposition.
