![]() However, some early building bricks were not designed to clamp together, rather relied upon gravity alone to hold structures together. The tiny difference in size between the nub and the stud receptacle must be compensated for elastically. Elasticity: By slightly deforming the stones during clamping, a permanent clamping or mechanical adhesive effect is achieved.Fit: Tolerances of a few micrometers prevent jamming, stepping, or detectable gaps between bricks.Recombinability: bricks can be arranged differently to each other again and again.Variability: as few as seven 4×2 bricks of the same color can be combined in over 85 billion ways.modularity: According to the construction set principle, the whole can be divided into parts and reassembled along defined locations. ![]() The design allows the parts to be connected with compressive force and the blocks to be clamped with plastic pins.Ĭharacteristics Kiddicraft and Lego Building blocks in different colors.Īccording to the systematics of science of play, most clamping building block systems belong to the game classification of educational toys or more specific construction toys.Ĭharacteristic features of building blocks are: The structured upper surface interacts by friction and positive locking with the correspondingly negative lower surface of other clamping components, so that complex designs can be assembled. The basic components are usually cuboid-shaped, cylindrically studded at the top in a grid pattern, hollow-bodied at the bottom and smooth at the sides. ![]() The Lego system is the most widely used clamp building block system in the world.īuilding blocks (also construction blocks) are modular construction parts, usually made of plastic, which can be assembled in a form-fit manner.
