In August 2015 Google announced that the launch of the long-awaited modular smartphone codenamed Project Ara was delayed. According to the official Project Ara Twitter account there were some problems with magnetic mounts, which caused the smartphone to fail drop test. No news since then.
Recently the source Patently Mobile revealed that the U.S. Patent and Trademark Office granted two design patents to Google. Both patents are related to Project Ara.
Unlike “patent applications”, design patents published by the U.S. Patent and Trademark Office don’t disclose information about a particular design. We can only look at the modular smartphone outlines, but it’s not possible to find our which materials or unique internal components were used.
From the pictures below we can see that Project Ara smartphone will still have the same endoskeleton with slots designed to hold interchangeable modules which provide different functionalities. Most likely that the main changes were related to the magnet mounts and some other components related to the whole robustness of the modular phone structure.
