MUMBAI, India, Nov. 21 -- Intellectual Property India has published a patent application (202511040746 A) filed by Vivaan Sabarwal; Aseem Dubey; Deepika Sandil; and Achal Kaushik, New Delhi, on April 28, for 'shape-memory alloy eyewear frames with enhanced durability and flexibility.'
Inventor(s) include Vivaan Sabarwal; Aseem Dubey; Deepika Sandil; and Achal Kaushik.
The application for the patent was published on Nov. 21, under issue no. 47/2025.
According to the abstract released by the Intellectual Property India: "The present invention relates to eyewear frames fabricated from a superelastic and shape memory alloy, specifically nitinol, manufactured through a laser powder bed fusion (LPBF) additive manufacturing process. The nitinol alloy utilized has a fixed atomic composition of approximately 51.2% nickel and 48.8% titanium, ensuring optimal mechanical performance. Nickel powder used in the process is sourced from recycled nickel-cadmium batteries, enhancing the sustainability of the manufacturing method. The LPBF process is meticulously controlled to prevent oxidation, achieve a fully dense frame structure without introducing voids or cavities, and preserve the alloy's superelastic and shape memory properties. Post-processing techniques including stress-relief annealing and surface finishing ensure the durability, corrosion resistance, and aesthetic appeal of the frames. The invention enables environmentally friendly production of customizable, lightweight, resilient eyewear frames, while simultaneously offering a scalable approach for commercialization through additive manufacturing technologies."
