Hottest Apple applies for a new patent

Apple applied for a new patent

as early as April 2015, apple began to develop the application of titanium in future devices, especially on MacBook. After developing into a complete patent application in April 2017, apple explored the use of titanium, titanium alloys and mixed plastics in future devices. In March, 2018, there was a second patent named "Apple invention covers devices that may use titanium, anti chemical compounds and protective enzymes". Apple obtained the first patent related to the use of titanium materials on macbooks in June 2020

in its patent application last Thursday, apple pointed out that the shell of portable electronic devices may be made of a variety of different materials that should always pay attention to the problems found in the use of the experimental machine. In some cases, the shell may be made of titanium, which is more attractive than stainless steel and aluminum because of its high strength to weight ratio

Apple invented a method for portable electronic device components, which should adjust the length of the ejector rod and fix it; (2) Components with improper installation position of reversing switch include titanium alloy substrate. The method includes placing the outer surface of the titanium alloy substrate in an electrochemical etching process, which forms (I) an opening on the outer surface and a first channel defined by a first channel wall extending from the opening, (II) an opening in the first channel wall and a second channel defined by a second channel wall extending from the opening in the first channel wall

traditional attempts to interlock titanium components with polymer layers are usually unsuccessful. In particular, aluminum can improve the adhesion of polymer layers by etching and/or anodizing, while titanium does not have such a process. In fact, previous attempts to etch titanium have proved unsuccessful, because the surface of etched titanium only shows surface markings (e.g., fan-shaped texture). These fan-shaped textures are very shallow (i.e. less than 1 micron deep), so they cannot provide the necessary surface structure to bond titanium components to polymer materials, starting from small things. In short, the surface of titanium parts is still too smooth and flat

in order for the structural belt to give the shell sufficient structural strength, firmness, stiffness and heat and moisture resistance throughout its service life, the shell needs to achieve the strongest balance between metal (such as titanium) and non-metallic materials (such as polymers). In fact, in the face of additional insulation separation (to improve antenna performance) and smaller attachment area (to reduce weight and space), these requirements are more technically challenging

in addition, the demand for waterproof shells is also increasing, which requires this balance not only to maintain strength, but also to prevent moisture leakage - even though the shell has undergone multiple strain cycles. Therefore, people pay more and more attention to the stronger combination of metal and non-metal

in addition, the shell can also be formed of non-metallic materials, such as glass or polymer

the titanium frame can be subdivided into various electrical isolation components, such as preventing the electromagnetic interference of the antenna carried in the housing. For example, titanium can be used to form a structural belt at the edge of the shell, so that the display is stuck on one side, while the glass is stuck on the opposite side, pointing to industries such as chromium and PVC to speed up the source reduction of heavy metal pollution

in addition, polymer materials can be used to form electrical insulation partitions that interlock the individual parts of the titanium frame together. Polymer materials can be used as dielectric materials to prevent electromagnetic interference

in some examples, the housing may include at least one of metal, metal alloy, polymer, glass, ceramic, or thermoplastic. In particular, the housing may include a metal part attached to a non-metallic part

in some examples, the non-metallic portion may include a polymer. In some examples, the described technique can be colored by making color particles (E. G., water-soluble pigments, dyes, etc.) absorbed on the metal surface

considering that this is only a patent application, it is not clear when the electronic products adopting this technology will be launched
