pr1or.art Inc., “Smart Fluid Applicator: AI-Powered Personalized Skin Care Device,” Published Technical Disclosure No. 24-11857055_0003_PTD, Published November 07, 2025, available at https://archive.pr1or.art/24-11857055_0003_PTD
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. 11,857,055.

Background and Problem Solved

The original patent described a fluid discharger and applicator device for household use, but it lacked the ability to provide personalized recommendations, track usage, and securely store user data. The new invention addresses these limitations by combining the original device with advanced technologies to create a more powerful and user-centric system.

Novelty and Inventive Step

The new invention's synergy of integrating AI, IoT, blockchain, and 3D printing technologies with the original fluid discharger and applicator device provides a non-obvious and innovative solution for personalized skin care and smart fluid application.

Alternative Embodiments and Variations

Alternative embodiments of the invention could include integrating the device with other technologies such as augmented reality or voice assistants to further enhance the user experience. Variations of the invention could include using different types of sensors or machine learning algorithms to improve skin analysis and fluid application.

Potential Commercial Applications and Market

The intelligent fluid discharger and applicator system has significant commercial potential in the beauty and cosmetics industry, with potential applications in personalized skin care, smart fluid application, and secure data storage. The system could be marketed as a premium product for consumers seeking advanced skin care solutions.

Field of Art

Personal care devices, fluid applicators, and medical/cosmetic technology with a focus on skin care delivery systems and user interaction interfaces

Person of Ordinary Skill (PHOSITA) Profile

A professional with expertise in biomedical engineering, product design, and consumer healthcare technologies, familiar with integrating sensors, software, and mechanical systems into medical and personal care devices
