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

An improved chair design featuring adjustable cleaning implement angles, detachable and dishwasher-safe cleaning implements, vacuum-powered cleaning, sanitizing UV light, and self-cleaning mechanisms to enhance user experience and hygiene.

Background and Problem Solved

The original chair with integrated cleaning implement had limitations in accommodating users with varying foot sizes, requiring frequent manual cleaning, and lacking advanced sanitizing features. The present inventive concept addresses these limitations by introducing innovative solutions to enhance user comfort, convenience, and cleanliness.

Detailed Description of the Inventive Concept

The enhanced chair features a cleaning system with an adjustable cleaning implement angle, allowing users to customize the angle according to their foot size. The detachable cleaning implement is designed to be dishwasher safe, reducing maintenance and increasing hygiene. Additionally, the chair incorporates a vacuum-powered cleaning implement, powered by a rechargeable battery, to provide more efficient cleaning. A sanitizing UV light is positioned to sanitize the cleaning implement and surrounding area, further enhancing cleanliness. Moreover, the chair features a self-cleaning mechanism that utilizes a water spray and brush combination to clean the cleaning implement, reducing user effort and increasing overall cleanliness.

Novelty and Inventive Step

The present inventive concept introduces a new level of customization, convenience, and hygiene to the original chair design. The adjustable cleaning implement angle, detachable and dishwasher-safe cleaning implement, vacuum-powered cleaning, sanitizing UV light, and self-cleaning mechanism collectively provide a novel and non-obvious solution that significantly enhances the user experience.

Alternative Embodiments and Variations

Alternative embodiments may include integrating the sanitizing UV light into the cleaning implement, using different types of cleaning implements, or incorporating sensors to detect foot size and automatically adjust the cleaning implement angle. Variations may also include designing the chair for specific industries, such as healthcare or hospitality, with tailored features to meet their unique needs.

Potential Commercial Applications and Market

The enhanced chair with advanced cleaning capabilities has significant commercial potential in various industries, including healthcare, hospitality, and education. The chair's innovative features can improve user satisfaction, reduce maintenance costs, and enhance overall cleanliness, making it an attractive solution for businesses and institutions seeking to provide a superior user experience.
