Dimple patterns for golf balls
The present invention provides a method for arranging dimples on a golf ball surface in which the dimples are arranged in a pattern derived from at least one irregular domain generated from a regular or non-regular polyhedron. The method includes choosing control points of a polyhedron, generating an irregular domain based on those control points, packing the irregular domain with dimples, and tessellating the irregular domain to cover the surface of the golf ball. The control points include the center of a polyhedral face, a vertex of the polyhedron, a midpoint or other point on an edge of the polyhedron and others. The method ensures that the symmetry of the underlying polyhedron is preserved while minimizing or eliminating great circles due to parting lines.
1. A golf ball having an outer surface comprising a plurality of dimples disposed thereon, wherein the dimples are arranged in multiple copies of a first domain and a second domain, the first domain and the second domain being tessellated to cover the outer surface of the golf ball in a uniform pattern having no great circles and consisting of four first domains and four second domains, and wherein:
the dimple pattern within the first domain is different from the dimple pattern within the second domain;
the plurality of dimples comprises dimples having three or more different diameters, including a minimum dimple diameter, a maximum dimple diameter, and one or more additional dimple diameters;
each dimple having the maximum dimple diameter is nearest neighbors with another dimple having the maximum dimple diameter;
each dimple having the minimum dimple diameter is nearest neighbors with another dimple having the minimum dimple diameter; and
each dimple having the minimum dimple diameter is nearest neighbors with a dimple having the maximum dimple diameter.
2. The golf ball of claim 1 , wherein the plurality of dimples comprises dimples having four or more different diameters, including the minimum dimple diameter, the maximum dimple diameter, a first additional dimple diameter, and a second additional dimple diameter.
3. The golf ball of claim 1 , wherein each dimple having the maximum dimple diameter is nearest neighbors with at least two dimples having the maximum dimple diameter.
4. The golf ball of claim 1 , wherein each dimple having the minimum dimple diameter is nearest neighbors with at least one dimple having the second smallest dimple diameter.
5. The golf ball of claim 1 , wherein each dimple having the minimum dimple diameter is nearest neighbors with at least two additional dimple diameters.
6. The golf ball of claim 5 , wherein the at least two additional dimple diameters includes the second smallest dimple diameter.
7. The golf ball of claim 1 , wherein each dimple having the minimum dimple diameter is nearest neighbors with at least three additional dimple diameters.
8. The golf ball of claim 7 , wherein the at least three additional dimple diameters includes the second smallest dimple diameter.
9. The golf ball of claim 1 , wherein each dimple having the maximum dimple diameter is nearest neighbors with at least one dimple having the second largest dimple diameter.
10. The golf ball of claim 1 , wherein at least one of the two domains includes at least one dimple having each of the different dimple diameters present on the ball.
11. The golf ball of claim 1 , wherein at least one of the two domains does not include a dimple having the minimum dimple diameter.
12. The golf ball of claim 1 , wherein both domains include a dimple having the maximum dimple diameter.
