Apple patent filing is for iOS, watchOS devices that are self-healing to be more waterproof

iPhone, iPad, and Apple Watch, heal thyself. Apple has filed for a patent (number 20170086321) for “self-energizing sealing mechanisms.” It involves electronic devices with a sealing mechanism to prevent ingress of water into the interior cavity. 

Apple wants to “enhance a user experience as well as for preventing harm to the internal components of electronic devices in high water content environments. In the patent filing, the company notes that as electronic devices become more ubiquitous, “it is beneficial to be able to use them in various environments without damaging the device, including when water is present.”

The sealing mechanism would sport a channel having a first opening at an external environment and a second opening that leads to the interior volume, a membrane that covers the second opening, the membrane being air permeable and water resistant such that the membrane allows air to pass and prevents passage of water up to an upper pressure threshold, a stopper mechanism, and a diaphragm comprising a surface arranged to receive an external water pressure. The surface would be air and water impermeable, the diaphragm being coupled to the stopper mechanism that deflects in response to the water pressure such that the diaphragm actuates the stopper mechanism and seals off the channel from at the first opening preventing water pressure at the membrane from exceeding the upper pressure threshold.

Of course, Apple files for — and is granted — lots of patents by the U.S. Patent & Trademark Office. Many are for inventions that never see the light of day. However, you never can tell which ones will materialize in a real product.
