Abstract

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.

Claims

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, wherein the first domain has four-way symmetry about the central point of the first domain and the second domain has three-way symmetry about the central point of the second domain, wherein the first domain and the second domain are tessellated to cover the outer surface of the golf ball in a uniform pattern consisting of six first domains and eight second domains, wherein the outer surface does not contain a great circle which is free of dimples, and wherein none of the dimples overlap, wherein the golf ball has one real mold parting line and three false parting lines that are identical in shape to the real mold parting line, wherein the six first domains and the eight second domains are defined by borders, wherein the entirety of the borders defining the first and second domains correspond to the real mold parting line and three false parting lines of the golf ball, and wherein none of the borders defining the first and second domains is a dimple-free straight line segment.
