Remember the Mac Pro’s cheese grater design everyone was talking about? Apple had 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. They’re now copying it to iPhones.
Apple is researching expanding the 2019 Mac Pro’s distinctive “cheese grater” lattice design to other devices, including the iPhone and a “trashcan”-style Mac Pro, according to a newly granted patent filing.
Apple is not shy when experimenting with new designs and tweaking its products. The company introduced the new iPhone 12 series with sharp edges and flat sides which have proved to be quite a hit. However, the company might change it in the future with something that we have already seen. That’s right, Apple’s new patents show a design for the iPhone that takes cues from the Mac Pro. The Mac Pro is famous for its ‘Cheese Grater’ design and now we can potentially see it on future iPhone models.
Apple Patents Mac Pro’s Cheese Grater Design for Future iPhone Models, Says it Will Strengthen the Design and Improve Performance
As mentioned earlier, the new patent granted to Apple highlights the possibility that Apple will use the Mac Pro’s ‘Cheese Grater’ design on future iPhone models (via PatentlyApple). Apple’s Mac Pro and Pro Display XDR were launched back in 2019 and the design of both products took the internet by storm, Today’s patent highlights the possibility of the design shifting to the iPhone lineup.
According to Apple, the ‘Cheese Grater’ design from the Mac Pro will allow better airflow to the processor whereby keeping it cool. This will also allow the device to push performance to the next level. In addition to this, Apple says that the design will be “visually interesting and aesthetically pleasing to the user.”
“The three-dimensional structures described herein can include, for example, a matrix of passageways that serves to greatly enhance the stiffness of the three-dimensional structure, without significantly increasing the size or weight of the structure. Thus, a relatively lightweight, yet extremely strong and stiff electronic device can be produced.”
Furthermore, the new design will also boast structural strength without having to increase the thickness of the device. In addition to this, the weight of the components would also be kept the same. Take note that the Cheese Grater design for the iPhone is just a patent at this stage and Apple files a lot of them. Henceforth, it is never certain that the design or product will see daylight any time soon.
The patent explains that “recent advances in electronic devices have enabled high levels of performance,” but many existing housing solutions are unable to “effectively distribute or reject heat generated by the electronic device to the surrounding environment,” thereby curtailing “the levels of performance of such devices.”
Apple believes that its lattice pattern presents a solution to this problem, since it increases a device’s surface area for better cooling and can more effectively “conduct heat away from a component of the electronic device positioned substantially adjacent to the first surface of the body.”
These enhanced levels of heat removal, as described above, can result in significant performance gains for the electronic device and can allow for the use of components or operating levels that heretofore may not have been achievable with existing three-dimensional structures.
In improving cooling, devices with the lattice pattern could push their processors to higher temperatures for better performance.
Illustrations included in the filing demonstrate how a miniaturized version of the lattice pattern could be milled directly into the iPhone’s outer frame and rear.
As well as significantly improving thermals, this could also improve grip, “provide a unique and pleasing look and feel,” and give “a pleasing experience when handling the device.”
In some cases, a three-dimensional structure can include a relatively intricate repeating pattern that, in addition to enhancing heat removal capabilities and providing stiffness, provides a visually interesting or aesthetically pleasing effect to the user. Such a three-dimensional structure, for example when used as a housing, can also include a variety of colors on one or more regions of the housing to enhance the visual appearance and provide a pleasing aesthetic experience to the user.
Another advantage of the lattice pattern is improved structural strength without increasing the thickness or weight of components.
When used as a housing or other structural component of an electronic device, a three-dimensional structure as described herein can provide a high level of strength and stiffness to weight ratio to the device. Traditional structures often achieve enhanced stiffness or strength by thickening or enlarging certain portions of the structure, often resulting in an increase in the weight and size of the electronic device, which may not be desirable to a user. The three-dimensional structures described herein can include, for example, a matrix of passageways that serves to greatly enhance the stiffness of the three-dimensional structure, without significantly increasing the size or weight of the structure. Thus, a relatively lightweight, yet extremely strong and stiff electronic device can be produced.
Another embodiment covers embedding the lattice internally inside the iPhone to improve rigidity and strength, allowing “the electronic device to be used over a long period of time while maintaining dimensional stability.”
The patent also mentions how the lattice structure “can act as shielding for the electronic device, while still allowing for air flow there through,” particularly as a shield against electromagnetic interference (EMI) and/or electromagnetic compatibility (EMC) noise.
In addition to the iPhone, Apple appears to have resurrected the divisive design of the 2013 Mac Pro, informally dubbed the “trashcan” Mac Pro, to demonstrate alternate embodiments for the lattice pattern.
Given that the lattice pattern debuted on the 2019 tower Mac Pro, it is interesting to see some of the latest Mac Pro’s design aspects implemented on an older model.
Although reversion to the trashcan-style design may seem more likely amid the transition to Apple silicon for a next-generation Mac Pro, the machine is in fact expected to look more like the Mac mini.
While patent filings cannot be taken as solid evidence of the Apple’s plans for actual consumer hardware, they can provide an interesting insight into the company’s areas of research. At a minimum, this patent indicates that Apple may be planning to bring its unique lattice pattern to more devices in the future, but only time will tell.
