Patent ID: 8206053

Claim:
A device that can be assembled by coupling, comprising: first and second body members configured to be coupled relative to each other; and a set of projections and surfaces associated with the first and second body members and configured to provide an interface between the first and second body members and position the first and second body members relative to each other via: first, second, and third contact areas that are each substantially linear and are collectively configured to receive loads and position the first and second body members relative to each other in five degrees of freedom, and a fourth contact area configured to limit positioning of the first and second body members relative to each other in a sixth degree of freedom in a first translational direction, wherein the first and second contact areas are at least partially defined by contact between a first projection on one of the first and second body members and first and second surfaces on the other of the first and second body members, wherein the third contact area is at least partially defined by contact between a second projection on the one of the first and second body members and a third surface on the other of the first and second body members, and wherein the second projection is substantially in a shape of a semi-cylinder.
