Summary of the Inventive Concept
A modular screw head assembly technology, originally designed for orthopedic fixation devices, is repurposed for securing and stabilizing components in renewable energy, marine, telecommunications, and aerospace industries, enabling robust and rigid constructs.
Background and Problem Solved
The original patent addressed the need for reliable bone fastener assemblies in spine surgery. However, the core technology of modular screw head assemblies can be applied to other industries where securing and stabilizing components is crucial. The new inventive concept tackles the limitations of conventional fastening systems in these industries, providing a more efficient and effective solution.
Detailed Description of the Inventive Concept
The modular screw head assembly consists of a tulip head, a saddle, and a bearing washer. In the new applications, the tulip head is attachable to various components such as wind turbine blades, solar panel frames, marine vessel hulls, telecommunications tower masts, and aircraft wing spars. The locking cap secures cables, support rods, mooring lines, guy wires, or control surfaces, restricting motion and forming a rigid construct. This technology enables the creation of robust and reliable systems in diverse industries.
Novelty and Inventive Step
The new inventive concept lies in the application of the modular screw head assembly technology to entirely different industries, leveraging its core benefits of reliability, efficiency, and effectiveness. The inventive step resides in the recognition of the technology's potential beyond orthopedic fixation devices and its adaptation to address specific challenges in these new industries.
Alternative Embodiments and Variations
Alternative embodiments may include modified tulip head designs, adjustable locking caps, or integrated sensors for real-time monitoring. Variations could involve using different materials, such as titanium or advanced polymers, to optimize weight, strength, and corrosion resistance.
Potential Commercial Applications and Market
The modular screw head assembly technology has significant commercial potential in the renewable energy, marine, telecommunications, and aerospace industries, where securing and stabilizing components is critical. The technology can be marketed as a customizable, reliable, and efficient solution for a wide range of applications, from wind turbines to aircraft wings.
