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. 11,857,066.

Background and Problem Solved

The original patent disclosed a customizable hairbrush with limited adjustability. The present invention addresses the limitations by introducing a hairbrush system with improved features, enhancing user experience and styling capabilities.

Novelty and Inventive Step

The new invention introduces novel features, including the improved ergonomic grip, integrated heating element, adjustable bristle angle, and integrated LED light, which are not present in the original patent. These features provide a significant improvement over the existing customizable hairbrush, making it more efficient, safer, and easier to use.

Alternative Embodiments and Variations

Alternative embodiments of the invention could include a hairbrush system with interchangeable bristle structures of varying materials, sizes, and shapes. The system could also be adapted for use with different types of hair, such as curly, straight, or wavy hair.

Potential Commercial Applications and Market

The enhanced customizable hairbrush system has significant commercial potential in the beauty and personal care industry, targeting professional stylists, salons, and individual consumers seeking high-quality, versatile hairbrushes for various styling needs.
