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. 11,857,177.

Summary of the Inventive Concept

The present inventive concept extends the core technology of the original patent to new, unexplored industries and use cases, leveraging the versatility of the spiral suturing needle and its associated mechanisms to address unique challenges in textile weaving, jewelry creation, pipeline repair, three-dimensional structure formation, and customized footwear manufacturing.

Background and Problem Solved

The original patent, focused on medical applications, has limitations in terms of its adaptability to other fields. This inventive concept tackles the problem of restricted applicability by applying the patented technology to diverse industries, thereby expanding its potential impact.

Detailed Description of the Inventive Concept

The inventive concept comprises a system or method that incorporates the spiral suturing needle, driving mechanism, recovery mechanism, and suture-taking-up mechanism from the original patent. In the textile weaving application, the spiral suturing needle is adapted for weaving yarns, while in jewelry creation, it is used to form a design pattern with the sutured material. For pipeline repair, the inner strut stretches the pipeline material, and the spiral suturing needle sutures along a path. In three-dimensional structure formation, the sutured material is a shape-memory alloy, and in customized footwear manufacturing, the spiral suturing needle forms a shoe upper with the sutured material. Each application requires specific adaptations and modifications to the original patented technology.

Novelty and Inventive Step

The inventive concept's novelty lies in its application of the spiral suturing needle and associated mechanisms to entirely new industries, demonstrating an inventive step beyond the original patent's medical focus. The new claims provide a non-obvious extension of the patented technology, addressing unique challenges in each target industry.

Alternative Embodiments and Variations

Alternative embodiments may include modifications to the spiral suturing needle's geometry, material, or operation, as well as variations in the driving mechanism, recovery mechanism, and suture-taking-up mechanism to suit specific industry requirements. Additional applications could include, but are not limited to, aerospace, automotive, or construction industries.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential, as it can be applied to various industries, including textile manufacturing, jewelry production, pipeline maintenance, three-dimensional printing, and footwear manufacturing. The target market includes companies and organizations operating in these industries, as well as research institutions and startups seeking innovative solutions.
