General waterproof solutions focus on the overall tightness of the port when it is not in use, while Apple's new patent can provide water tightness at the port connection when the device is connected to an accessory. Applying a deformable seal design allows the port connector to be "liquid-tight", which allows the connector to be used in wet, dry environments. The patent description generally describes a series of methods for creating a confinement when a connector is connected to a port, rather than the protective nature of the connection port. Included in the connector access port, the rubber ring of the connector seals the area. Another method is to apply a deformed material that creates a seal when inserted into the interface. The patent also mentions the use of vacuum generators for additional protection measures.
