MUMBAI, India, Feb. 27 -- Intellectual Property India has published a patent application (202541134109 A) filed by Kongunadu College Of Engineering And Technology; Dr. T. Rajamanikandan; Mr. N. M. Mohan Karthik; Priyadharshini S; Dr. S. Kavipriya; Dr. J. Yogapriya; Dr. C. Saravanabhavan; Mrs. K. Yazhini; K. Karthik; and K. Mohanraj, Trichy, Tamil Nadu, on Dec. 31, 2025, for 'a foldable buoyancy assisted footwear system with deployable petal structures for controlled mobility over water surface.'

Inventor(s) include Kongunadu College Engineering And Technology; Dr. T. Rajamanikandan; Mr. N. M. Mohan Karthik; Priyadharshini S; Dr. S. Kavipriya; Dr. J. Yogapriya; Dr. C. Saravanabhavan; Mrs. K. Yazhini; K. Karthik; and K. Mohanraj.

The application for the patent was published on Feb. 27, under issue no. 09/2026.

According to the abstract released by the Intellectual Property India: "The present invention relates to a foldable buoyancy-assisted footwear system configured to enable controlled mobility over water surfaces while functioning as a conventional shoe during land use. The footwear system comprises a shoe body having an upper portion, a midsole, and an outsole, within which a sole cavity is formed. A plurality of petal-like buoyant panels are radially arranged around the sole cavity and are pivotally connected to the shoe body through hinge mechanisms. In a land mode, the petal-like buoyant panels remain folded within the sole cavity, allowing normal walking. Upon exposure to water, the panels deploy outwardly to form an enlarged buoyant support surface beneath the shoe body, thereby increasing effective surface area and providing buoyancy. Deployment may occur passively through buoyant forces or actively through sensot-assisted actuation. A locking mechanism secures the panels in the deployed configuration, and a retraction mechanism enables automatic folding upon exit from water. The invention provides a compact, wearable solution suitable for recreational, emergency, and rescue applications."
