Apple reveals uses for Sapphire Glass in new patent app

United States Patent and Trademark Office published an Apple patent application detailing methods of using and mounting sapphire to mobile devices.
 

 
The application supposedly describes a system in which sapphire could act a display’s cover glass and gives insight how the material could be used to dissipate heat generated by a device. It describes the difficulty in attaching sapphire to existing materials and notes the current implementation of sapphire as a cover for the rear camera oh the iPhone.
 

Apple reveals effective methods for using sapphire as a cover glass would involve creating an aperture within a sapphire substrate, after that using a second material with a lower melting point like metal or plastic to pour into the aperture.

The joining of the substrate and the filling of the second material would then act as attachment point for other materials that can be welded, soldered, or secured.
