    • 专利摘要:
    Random number generator formed by a polyhedral central body and a set of protrusions (3), in which symbols (5) have been drawn around the vertices (4) of said polyhedral central body. The protrusions (3) start from all the flat facets (2) and are firmly anchored to the polyhedral central body with normal direction to the facet (2). The symbols (5) represent elements of a set and are selected when the device is launched, the result corresponds to the symbol at the top of its surface when it ends up reaching a stable equilibrium position on the protrusions (3).

    the surface, such as numerical digits, letters of any alphabet, colored dots or icons that represent actions, which can subsequently be interpreted as the corresponding elements of the cited set.
    The device works similarly to a conventional die, it is thrown and after falling and traveling bouncing a distance on a flat surface, it ends up reaching an equilibrium position in which the symbol exposed in the upper area of the central body of the device represents the element chosen in the set.
    However, unlike conventional dice, the dual generator is composed of a polyhedron-shaped solid to which protrusions have been added on all of its flat faces. Said polyhedron can be of any type and acts as a central body. The central area of the polyhedron facets serves as the basis for the protrusions, while the area immediately near the vertices has drawn on its surface symbols that represent the selectable elements of a set.
    Logically, the number of selectable elements (and with that, the size of the set) is limited by the number of vertices of the polyhedron. The variety of polyhedra that can be used as a central body is practically unlimited, since there are no restrictions regarding its regularity or symmetry.
    Only two conditions must be met: The generator must have a minimum number of facets with protrusions (in most cases it is sufficient with 4, although it depends on its distribution) so that it can support and reach the equilibrium position. In addition, it must be ensured that in all equilibrium positions there is a vertex with a selectable symbol on the upper part of the polyhedral central body.
    Each protrusion extends radially, in the direction of the normal of the face on which it sits.
    The protrusions can have many forms: cubes, spheres, prisms with any type of geometric base, pyramids, cylinders, etc. being desirable that they share the same form for all protrusions that belong to the same generator.
    The length from the center of masses of the polyhedron to the end of each of the protrusions is greater than the length from the center of masses to any of the points on the surface of the flat faces. Therefore, when it hits and rolls it only makes contact with the protrusions (and not with the surface of the central polyhedral body).

    a regular spherical network. This is a restriction that depends on the polyhedron used as the central body and the regularity of the faces on which the protrusions are placed.
    The dual random number generator can have a very large number of selectable elements and be used comfortably. The dice of more than 32 faces made with regular polyhedra for practical purposes are similar to spheres because of their rolling capacity. While the dual generator, not rotating on a plane with the same ease, does not travel such a large distance when launched.
    The protrusions can be made of the same material as the polyhedral central body, or of other materials that confer certain properties. For example, metal, which provides greater durability against blows that occur in rebounds, or rubber, which has greater rebound capacity.
    Given the external shape of the dual generators, they can cause serious injuries if accidentally swallowed. Therefore, it is not advisable that they be used or handled by young children.
    A variant of the dual generator to highlight is that the set of protrusions does not necessarily have the same length from the face on which it sits to the furthest end. But that length is adapted so that the distance between the center of mass of the generator and the furthest end of the protrusions is the same for all. BRIEF DESCRIPTION OF THE DRAWINGS
    To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, a set of drawings is attached as an integral part of said description, where illustrative and non-limiting nature has been represented. next:
    Figure 1.- Shows a perspective view of two dual random number generators with icosahedral central body with triangular base prism-shaped protrusions. Each of them is in a different orientation so that the placement of the protusions in the center of the faces and the symbols around the vertices can be seen on its three-dimensional surface. Both generators are in positions close to that of equilibrium, so that the result is shown around the vertex that looks up.
