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. 11,857,080.

Background and Problem Solved

The original patent disclosed a sheet fastener for fastening sheet edge portions of a pair of sheet members together. However, the limitations of the original patent are that it only considers applications in the automotive and furniture industries. This new invention addresses the problem of efficiently and securely assembling wind turbine blades by applying the core technology of the original patent to this novel field.

Novelty and Inventive Step

The new claims introduce the novel application of sheet fasteners in the wind turbine industry, providing a non-obvious solution to the problem of assembling wind turbine blades. The inventive step lies in the adaptation of the original patent's technology to this new field, enabling the creation of a more efficient and secure assembly system.

Alternative Embodiments and Variations

Alternative embodiments of the invention could include the use of different materials or geometries for the fastening members, or the integration of sensors or monitoring systems to detect and respond to blade damage or wear. Variations could also include the application of this technology to other industries, such as aerospace or construction.

Potential Commercial Applications and Market

The wind turbine blade assembly system has significant commercial potential in the renewable energy industry, where efficient and cost-effective assembly solutions are critical. The market for this technology is expected to grow as wind energy becomes an increasingly important contributor to global energy production.
