Hartley Charlton, MacRumors:
Apple introduced an innovative milled lattice pattern on the Mac Pro and Pro Display XDR in 2019, which is created by machining a spherical array into the internal and external surfaces of the aluminum. The result is a lightweight lattice pattern that maximizes airflow while creating an extremely rigid structure.
The new patent, first spotted by Patently Apple and granted by the U.S. Patent and Trademark Office, is titled “Housing construction” and covers expanding the lattice pattern to other devices, such as the iPhone.
Look at that first image. When I saw the article, then the image, my first thought was a check of the date. Nope, too early for April Fools Day. This appears to be a real patent filing.
Here’s a link to the actual patent, with a page showing the cheese grater on the sides of an iPhone.
Still can’t wrap my head around the use case here. A cheese grater on a device Apple worked so hard to waterproof? Not getting it.
