Apple wins patents for mobile ‘cheese grater’ design
- Apple has been granted two patents for iPhone-like devices that feature the well-known 'cheese grater' design.
- The open lattice pattern increases airflow to components, allowing for better airflow, according to Apple.
- This comes two years after the striking design debuted in the 2019 Mac Pro and Pro Display XDR.
According to Patently Apple, Apple has been granted patents for their 3D structural lattice design known colloquially as the ‘cheese grater’ for its resemblance to the kitchen tool. The design was acclaimed for its light weight and durability as well as its benefits to airflow (and therefore thermal performance) on both the Mac Pro and Pro Display XDR. Now, it appears that Apple may reintroduce the design, but this time for one of its non-professional focused devices; the iPhone.
As reported by Patently Apple, two patents have been granted to Apple regarding the ‘cheese grater’ design:
Patent Claim #1:
An electronic device, comprising: a body having a first surface and a second surface opposite the first surface; the body defining a pattern of repeating base units extending between the first surface and the second surface, each base unit comprising; a first spherical cavity on a first plane; a second spherical cavity on the first plane and at least partially intersecting the first spherical cavity; a third spherical cavity on the first plane and at least partially intersecting the first spherical cavity and the second spherical cavity; a fourth spherical cavity on a second plane, the fourth spherical cavity intersecting the first spherical cavity, the second spherical cavity, and the third spherical cavity to form a through hole passing between the first plane and the second plane.
Patent Claim #10:
A housing for an electronic device, comprising: a body having a first surface and a second surface; the body defining a first set of spherical cavities extending into the body; the body defining second set of spherical cavities extending into the body and eccentrically intersecting the first set of spherical cavities to form a hexagonally close-packed pattern of spherical cavities in fluid communication with a first set of apertures defined by the first surface and a second set of apertures defined by the second surface.
In these patents, Apple describes the lattice design exactly, with its three intersecting half spheres that line up to become the ‘cheese grater’. Although the design is unconventional, the apparent benefits to airflow are vast enough for Apple to consider the use of the design. Apple’s reasoning for the research into the use of this design for the iPhone may be the performance increase it could yield. The lattice design allows significantly more air to flow into the machine, which helps maintain cooler temperatures for the system.
