Method of creating a 3D assembly puzzle

Abstract

The invention relates to methods for creating three-dimensional puzzles that require disassembling an initial volumetric figure into individual components and then reassembling the individual components into the initial volumetric figure. The technical result is the creation of three-dimensional puzzles that have arbitrary volumetric figures as initial ones, the degree of complexity of assembly of which can vary widely from the simplest to the most complex. The component parts of the puzzles according to the claimed method are formed by cutting the initial puzzle figure with two groups of secant surfaces rotated in space relative to each other by 90 degrees, wherein the secant surfaces used to obtain the component parts are constructed based on guide lines with contours of a special shape. A description of the construction of contours of a special shape for forming secant surfaces is given in the claimed method.

1 . A method for creating a three-dimensional prefabricated hand puzzle representing a volumetric figure of arbitrary shape consisting of parts that, when assembled, form the original volumetric figure of the puzzle, characterized in that the component parts of the puzzle are formed by cutting the original volumetric figure of the puzzle with two groups of secant surfaces, wherein each group of secant surfaces contains one or more secant surfaces, and the direction of the contour lines of the secant surfaces both within one group of surfaces and between surfaces belonging to different groups coincides, wherein the angle between the generating lines of the secant surfaces belonging to different groups is 90 degrees, and the secant surfaces belonging to one group must have contour lines as guides that do not intersect with other contour lines of the surfaces of this group, and must have the same direction as other contour lines of the surfaces of this group, where the direction of the contour line is determined as the direction between the start and end points of the contour line, wherein the contour lines of each secant surface serving as guides in constructing the secant surfaces, are constructed in the form of a chain of one or more basic contour elements, defined in paragraph 2 of this claim, connected by smooth lines (without breaks), while the number of basic contour elements included in the composition of different contour lines of different cutting surfaces may be different and the parameters of different basic contour elements may differ from each other. 
     
     
         2 . A method for constructing a basic contour element, characterized in that it consists of constructing a line from two curves and connecting them in such a way that one of the curves has the form of two zigzags like a capital letter ‘S’, the other is a symmetrical reflection relative to the vertical line at some distance along the horizontal of the first curve and thus having the form of a mirror image relative to the vertical axis of the capital letter ‘S’ and a smooth (without kinks) connection of the upper vertices of these two curves by a line that has a downward bend, towards the unconnected vertices, wherein the parameters of the right and left curves (in the form of the letter S and its reflection)—the radii of rounding, the lengths of various sections, the orientation angles of the lines—can differ from each other for the same basic contour element, that is, the basic contour elements can consist of asymmetrical left and right curves.
