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. 11,857,086.

Summary of the Inventive Concept

A next-generation chair system that integrates advanced technologies such as artificial intelligence, computer vision, and nanotechnology to provide a comprehensive foot cleaning and personalized hygiene experience for users.

Background and Problem Solved

The original patent for a chair having a cleaning implement integrated thereon addresses the problem of dirty feet, but it has limitations in terms of its manual operation, limited cleaning capabilities, and lack of personalization. The new inventive concept builds upon the original idea by incorporating advanced technologies to provide a more efficient, effective, and personalized foot cleaning experience.

Detailed Description of the Inventive Concept

The smart chair system comprises a self-cleaning module integrated into the chair's frame, which utilizes artificial intelligence to detect and remove dirt, debris, and other unwanted substances from the user's feet. The system also includes an integrated personal hygiene assistant that uses computer vision and machine learning to detect and provide personalized cleaning recommendations for the user's feet. Additionally, the system features interchangeable cleaning modules, each designed to address a particular type of foot impurity, and a nanotechnology-based cleaning surface that utilizes molecular-level interactions to attract and remove dirt and debris. The system can also be integrated with a wearable chair accessory comprising a portable foot cleaning device that utilizes ultrasonic waves and gentle vibrations to clean and massage the user's feet.

Novelty and Inventive Step

The new claims introduce a paradigm shift in foot cleaning technology by incorporating advanced technologies such as artificial intelligence, computer vision, and nanotechnology. The integration of these technologies provides a more efficient, effective, and personalized foot cleaning experience that is not possible with the original patent's manual operation and limited cleaning capabilities.

Alternative Embodiments and Variations

Alternative embodiments of the smart chair system could include a standalone foot cleaning device that can be used independently of the chair, or a modular system that allows users to customize their foot cleaning experience with different cleaning modules and accessories. Variations of the system could also include integration with other health and wellness technologies, such as fitness trackers or health monitoring systems.

Potential Commercial Applications and Market

The smart chair system has significant commercial potential in various industries, including healthcare, hospitality, and fitness. The system could be marketed as a premium product for high-end gyms, spas, and hotels, or as a medical device for healthcare providers. The wearable chair accessory could also be marketed as a standalone product for consumers who want a convenient and effective foot cleaning solution.

Field of Art

Furniture design and personal hygiene technologies, with expertise in ergonomic seating systems and integrated cleaning mechanisms

Person of Ordinary Skill (PHOSITA) Profile

An engineer with advanced knowledge of furniture design, mechanical systems, and personal cleaning technologies, capable of integrating multiple technological approaches to solve user-centric problems

Obviousness Rationale

A person of ordinary skill would recognize that the source patent's basic foot cleaning chair concept provides a clear technological foundation for advanced cleaning and personalization technologies. The PTD's variations represent predictable extensions of the original cleaning chair concept by applying known artificial intelligence, computer vision, and nanotechnology techniques to an existing cleaning chair framework. The core functional elements of detecting, removing, and addressing foot contamination remain consistent between the source patent and the PTD, with the primary difference being the sophistication of the implementation.
