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. 11,857,439.

Summary of the Inventive Concept

An innovative system and method for manufacturing customized sleeves for prostheses, offering improved durability, comfort, and hygiene, while reducing production time and waste.

Background and Problem Solved

The original patent disclosed a method for manufacturing customized sleeves for prostheses, but it had limitations in terms of material durability, manufacturing efficiency, and infection risk. The new inventive concept addresses these limitations by introducing advanced materials, 3D printing technology, and antimicrobial coatings, enabling the production of high-quality customized sleeves with enhanced comfort, grip, and stability.

Detailed Description of the Inventive Concept

The enhanced system comprises a mold holder, a preform injector, and a temperature control system, designed for high-volume production and minimal waste generation. The preform is manufactured using 3D printing technology to achieve a precise fit and optimal comfort for the individual. The preform is made of a hybrid elastomer material with improved durability and resistance to wear, and an outer layer of a bi-component silicone with enhanced grip and stability. Additionally, the preform can be treated with an antimicrobial coating to reduce the risk of infection and promote healthy skin conditions.

Novelty and Inventive Step

The new claims introduce the use of 3D printing technology, hybrid elastomer materials, and antimicrobial coatings, which are not present in the original patent. These innovations provide a significant improvement in terms of comfort, durability, and hygiene, making the new inventive concept non-obvious and novel compared to the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include the use of different materials, such as advanced polymers or nanomaterials, or the integration of sensors and monitoring systems to track the performance and health of the customized sleeve. Variations of the system could also be designed for specific types of prostheses or individuals with unique needs.

Potential Commercial Applications and Market

The enhanced customized sleeve manufacturing system has significant commercial potential in the prosthetics industry, with potential applications in hospitals, clinics, and rehabilitation centers. The target market includes individuals with limb loss or impairment, as well as healthcare providers and manufacturers of prosthetic devices.
