Abstract: A tolerance absorbing spacer for controlling manufacturing dimensional tolerance variation in products made with multiple internal components, each requiring unique dimensional tolerance allowance. This component adjusts and compensates for the resulting overall cumulative component height variation within an assembly of components, sometimes referred to as “stack height” by compensating for the maximum to minimum range of possible assembly heights, compressing and yielding under applied external force until all excess internal clearance is removed, except for a small, and desirable remaining clearance. This component yields and becomes essentially fully plastic, to provide the necessary tolerance adjustment feature only after reaching a predetermined, minimum force which exceeds all applied forces the component could reasonably encounter in service use and below which, the tolerance absorbing spacer remains fully rigid.

Abstract: The present disclosure includes an ultrasound diagnostic apparatus with easy assembly and disassembly. The apparatus comprises an outer casing including a motherboard module having motherboard guiding plugs and motherboard ports installed thereon and a first outer-casing sliding device; and a main case structure being housed by the outer casing, including a transducer panel module coupled to an I/O module, a carrier board module coupled to the transducer panel module via the I/O module and having a PC module installed thereon process ultrasound data, carrier-board guiding holes to receive the motherboard guiding plugs, carrier-board ports to inter-plug in the motherboard ports, and a first main-case sliding device to slide in the first outer-casing sliding device and facilitate the main case structure to move relative to the outer casing; wherein the motherboard module and the I/O module are perpendicular to the transducer panel module and the carrier board module.
