Housing Assemblies

A housing assembly for a computing device, the housing assembly comprising:

• a stainless-steel elongated side-frame element formed through machining, the elongated side-frame element comprising:
• at least one elongated slot disposed on an inner surface thereof, the elongated slot oriented parallel to the elongated side-frame element, the elongated slot comprising:
• an open first channel, the open first channel defining an aperture in a sidewall face of the elongated side-frame element;
• at least one undercut, the undercut including at least one second channel connected to the open first channel;
• and
• at least one gap defined through the elongated side-frame element, the gap dividing the elongated side-frame element into a plurality of elongated sidewall elements, the elongated sidewall elements configured to allow for isolation between multiple antennas of the computing device;
• and
• an internal-frame element formed through casting, the internal-frame element formed of at least one of an aluminum material, an aluminum alloy material, a magnesium material, or a magnesium alloy material, the internal-frame element comprising:
• an internal frame body;
• and
• an elongated interlock flange extending orthogonally from the internal frame body, the elongated interlock flange cast into the elongated slot of the elongated side-frame element, the elongated interlock flange including a seat, the seat engaging the undercut of the elongated side-frame element.

A method of manufacturing a housing assembly for a computing device, the method comprising:

• forming an elongated side-frame element of a first metal material;
• machining at least one elongated slot into an inner surface of the elongated side-frame element, the elongated slot oriented parallel to the elongated side-frame element, the elongated slot including at least one undercut;
• and
• casting a second metal material into the elongated slot and undercut to form an internal-frame element, the second metal material a different material than the first metal material, the first metal material having a higher melting point than the second metal material.
