Abstract:
1. A brick assembly, comprising: a rod brick with an irregular polygon-shaped cross-section, having an identification IC (Integrated Circuit) and at least one contact connected to the identification IC (Integrated Circuit) and located on an outer surface of the rod brick; a sleeve brick, having a circumferential wall defining an internal bore, the internal bore having the same shape with the cross-section of the rod brick to make the rod brick insert into the sleeve brick only in one direction, the sleeve brick comprising: a frame brick, having an identification IC (Integrated Circuit) and a plurality of through holes for placing the sleeve brick, each through hole including at least one contact accordance with the outer contact of the sleeve brick; wherein when the rod brick inserts into the sleeve brick and the sleeve brick places in one of the through hole of the frame brick, the contact of the rod brick contacts to the inner contact of the sleeve brick and the contact of the frame brick contacts to the outer contact of the sleeve brick; signals, caused by the resistor of the sleeve brick, of the identification IC (Integrated Circuit) of the frame brick are detected by a computer system to recognize connecting relationship of the rod brick, the sleeve brick and the frame brick.
