Apple has been granted U.S. patent number US 11,678,445 B2 by the U.S. Patent and Trademark Office (USPTO) for a patent titled “Spatial Composites.” This patent focuses on enhancing the scratch resistance of device casings by embedding materials like metal and ceramic into the housing. While metal casings are strong, they can interfere with radio signals, and plastic casings, although transparent to radio signals, are prone to scratches. Ceramic casings, on the other hand, allow radio signals and are scratch resistant but have a risk of being brittle. The patent suggests a combination of metal, ceramic, plastic, and glass to create a composite housing that balances strength, toughness, shatter resistance, radio transparency, and scratch resistance. These materials can have different shapes and sizes, including spherical or bead-like shapes with interconnecting structures for better durability.
Apple receives a patent allowing it to use various materials to manufacture more durable device housing
Through the manipulation of surface density, Apple has the potential to alter the structural qualities of the abrasion-resistant materials, such as stiffness, hardness, and flexibility. For instance, by adjusting the surface densities, Apple could increase the stiffness of the housing corners for added protection against scratches and abrasions, while strengthening other sections to enhance durability.
Apple mentions that these housings can be applied to mobile phones, watches, tablets, laptops, and other devices. However, it remains to be seen whether Apple will utilize this patent, as they receive numerous patents each year but only a small percentage are actually implemented in their products.
