摘要： In a three-dimensional sheet puzzle, puzzle pieces fit together to form a shell held by magnetic attraction to a ferromagnetic base. The puzzle pieces are formed from sheet material which lies flat without strain. The shapes of the pieces are slightly distorted when applied to the spherical base. The puzzle is produced by first forming a flexible cover on the base, cutting the cover into pieces, flattening the resulting pieces, cutting pieces from the flexible flat sheet material conforming in shape to the flattened pieces cut from the spherical cover, fitting the pieces of flexible flat sheet material together on the base to recover the spherical base, depicting a puzzle design on the cover formed from the pieces of flexible flat sheet material, laying the pieces of flexible flat sheet material flat again, reproducing the flattened pieces on flexible flat sheet material and cutting out the reproduced pieces from the flat sheet material. In one embodiment, the puzzle is spherical and is another embodiment, the puzzle is curved along two surface dimensions with variation in the radii of curvature and specifically is in the form of a human head.

摘要翻译： 在三维拼图中，拼图拼接在一起以形成由磁吸引到铁磁基座的外壳。 拼图片由没有应变的平坦的片材形成。 当应用于球形基底时，片的形状稍微变形。 该拼图通过首先在基座上形成柔性盖，将盖切成片，使所得片平坦化，将其从与球形盖切割的扁平片形状的柔性扁平片材切割而成， 柔性平片材料一起在基座上以回收球形基座，描绘了由柔性平片材料片形成的盖上的拼图设计，将柔性平片材料片再次平放，将柔性平片上的扁平片再现 从平板材料切出再现的片材。 在一个实施例中，拼图是球形的，并且是另一个实施例，拼图沿着具有曲率半径变化的两个表面尺寸弯曲，并且具体地以人头的形式。
