Inflatable Structure Drain System Using Sliding Seal

The patent removes the hook-and-loop fastening mechanism from the drain assembly and replaces it with a simple snap-fit closure system. The drain flap is secured to the inflatable structure through a straightforward snapping action that eliminates wear-prone fasteners while maintaining ease of operation and improving long-term reliability.

The patent employs a simple, inexpensive snap-fit closure mechanism that is more durable than hook-and-loop fasteners but can be easily replaced if needed. This approach prioritizes long-term reliability through a simpler design that doesn't rely on complex fastening systems prone to degradation.

The patent extracts the complex hook-and-loop fastening system and replaces it with a simple snap-fit closure mechanism that is easier to manufacture and more durable. The drain assembly uses basic sealing elements and straightforward fastening geometry that can be produced with standard manufacturing processes while ensuring long-term reliability.

The patent divides the drain assembly into separate functional components: the drain flap, the closure mechanism, and the sealing elements. This segmentation allows each component to be optimized independently, with the closure mechanism designed for simplicity and durability while the sealing elements ensure proper air containment without complex fastening systems.
