MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202611107299 A) filed by Chandigarh University on September 07, 2026, for A Self-Actuating Passive Liquid Evacuation System For Portable Enclosures.
Inventors include Kush Kumar; and Khushi Singh.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: The present invention discloses a self-actuating, gravity-driven liquid evacuation system for portable enclosures configured to protect stored contents from liquid accumulation. The system comprises an elevated dry-zone isolation platform positioned above a non-planar, gravity-induced sloped floor, thereby creating a fluid- isolation chamber between the stored contents and a drainage region. Liquid entering the enclosure is guided by the sloped floor toward a predetermined collection point and passes through an integrated debris filtration barrier. A hydrostatic pressure-responsive unidirectional valve positioned at the collection point automatically opens when accumulated liquid generates sufficient pressure, permitting outward liquid evacuation, and subsequently returns to a normally closed condition to restrict reverse ingress of water, dust, and debris. The system operates passively using gravity and hydrostatic pressure without batteries, sensors, external power, or manual intervention, and may be integrated into or retrofitted within backpacks, laptop bags, luggage, equipment cases, and other portable enclosures.
