Snap-on module for selectively installing receiving element(s) to a mobile device

A modular device comprising:

• a mobile device that includes a casing and a processor protected by the casing, wherein the casing includes a first end and a second end, and wherein the second end exposes an electronic interface that is operably coupled to the processor;
• at least one battery that resides internally within the casing of the mobile device, wherein the electronic interface of the mobile device is designed to dock with a charger that distributes power to the at least one battery;
• a module that physically and electrically engages to the electronic interface at the second end of the mobile device, wherein engagement establishes a communication path between the module and the processor;
• one or more receiving elements that are assembled externally to and are positioned toward the first end of the casing of the mobile device, wherein the one or more receiving elements comprises at least one of antennas or sensors;
• and
• one or more media routing conduits each comprising an end and positioned externally alongside the casing of the mobile device, the one or more media routing conduits interconnecting the one or more receiving elements, respectively, to the module, wherein the one or more media routing conduits are configured to carry signals from the one or more receiving elements assembled externally to the first end of the casing of the mobile device to the processor via the module engaged to the electronic interface at the second end of the mobile device;
• wherein the module comprises connectors configured to frictionally engage, physically couple with, and electronically interface to the ends of the one or more media routing conduits.
