pr1or.art Inc., “AI-Powered Hair Treatment Dispenser: Personalized Care Tech,” Published Technical Disclosure No. 24-11857051_0006_PTD, Published October 27, 2025, available at https://archive.pr1or.art/24-11857051_0006_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. 11,857,051.

Background and Problem Solved

The original patent disclosed an adjustable composition dispenser with dynamically adjustable protrusions, bristles, or tines. However, it lacked user-centric customization and automation. The new invention addresses this limitation by integrating a user interface, ergonomic design, and sensor technology to provide a more efficient, comfortable, and personalized hair treatment experience.

Novelty and Inventive Step

The new invention introduces a user-centric approach to hair treatment by integrating a user interface and sensor technology, enabling real-time adjustment of the composition dispenser. This novel combination of features provides a significant improvement over the original patent, offering a more personalized and efficient hair treatment experience.

Alternative Embodiments and Variations

Alternative embodiments of the invention could include a mobile application for remote selection of hair length and treatment settings, or a wearable device that detects hair length and type and transmits the data to the composition dispenser. Variations of the invention could also include different materials and geometries for the protrusions, bristles, or tines, or the integration of additional features such as temperature control or vibration.

Potential Commercial Applications and Market

The customizable hair treatment system has significant commercial potential in the beauty and personal care industry, particularly in the hair care segment. The invention could be marketed as a premium product, targeting professional hairstylists and salons, as well as individual consumers seeking a more personalized hair treatment experience.

Section 103 Obviousness Analysis (PHOSITA)

▼

Field of Art

Cosmetic applicator design and hair treatment technology, focusing on adjustable dispensing systems with specialized protrusion mechanisms for targeted product application

Person of Ordinary Skill (PHOSITA) Profile

A professional with expertise in mechanical engineering, cosmetic product design, and user interface development, possessing knowledge of materials science, ergonomics, and consumer product innovation

Obviousness Rationale

A person of ordinary skill would recognize that the PTD's variations represent predictable extensions of the source patent's core technology of adjustable composition dispensers. The fundamental concept of dynamically modifying protrusion length and configuration is already established in the source patent, making the PTD's additional user interface and sensor-based adaptations a logical progression of known design principles. The incremental improvements in user interaction and automated adjustment would be considered obvious modifications to an existing technical framework.

Obvious Combinations & Variations

Source Patent Element

Adjustable protrusion unit with linear axial travel and rotation mechanism

PTD Variation

Integration of user interface and sensor technology to automatically adjust protrusion length

Obviousness Reasoning

Predictable application of electronic control systems to mechanical adjustment mechanisms, representing a known technique for enhancing user experience and precision

Source Patent Element

Composition dispenser with multiple protrusion elements and dispensing orifices

PTD Variation

Modular protrusion units with interchangeable configurations for different hair lengths and types

Obviousness Reasoning

Obvious design variation utilizing known modularity principles to expand product versatility and accommodate user-specific requirements

Source Patent Element

Twist top configuration for protrusion length adjustment

PTD Variation

Mobile application and wearable device integration for remote protrusion configuration

Obviousness Reasoning

Predictable extension of mechanical adjustment concept into digital control domain, representing a standard approach to modernizing existing mechanical technologies

Source Patent Element

Bristle-based protrusion elements for composition delivery

PTD Variation

Ergonomic handle design with contoured grip to reduce user fatigue during application

Obviousness Reasoning

Routine ergonomic optimization of existing device, representing a standard design improvement approach in consumer product development

35 U.S.C. § 103 Summary: Based on the teachings of US Patent 11857051 and the published technical disclosure, a person of ordinary skill in the art would find the claimed variations obvious and anticipated. The incremental technological improvements represent predictable combinations of known techniques in composition dispenser design, thereby rendering subsequent claims involving similar mechanisms obvious and unpatentable under 35 U.S.C. Section 103.
