<p>A quadrate tridimensional puzzle comprises six main bodies (1), twelve side connection parts (2) and eight corner connection parts (3). Each of the main bodies (1) assembled by multi-planar pieces (11) has a flat-plate structure. Incising a flat plate forms the multi-planar pieces (11). Each of the side connection parts (2) connects every two vertical crossed main bodies (1) and has a structure of a quarter of columnar. Multi-curved pieces (21) incised from a one-quarter columnar are assembled to form the side connection part (2). Each of the corner connection parts (3) connects every three vertical crossed main bodies (1) and has a eighth sphere structure. Multi-spherical pieces (31) incised from a eighth sphere are assembled to form the corner connection part (3). The radius of the cross section of the one-quarter columnar is equal to the radius of the eighth sphere. By using three kind of standardized pieces, i.e. the planar piece (11), the curved piece (21) and the spherical piece (31), they can be assembled to form a quadrate tridimensional product with compass transitional edges integrally.</p> |
