Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 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 three-way rotational symmetry about the central point of the first domain and the second domain has four-way rotational 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, wherein the uniform pattern consists of eight first domains and six second domains, and wherein the outer surface does not contain any great circles. 2. The golf ball of claim 1 , wherein the outer surface of the golf ball comprises 336 dimples. 3. The golf ball of claim 1 , wherein the outer surface of the golf ball comprises 360 dimples. 4. The golf ball of claim 1 , wherein the outer surface of the golf ball comprises 384 dimples. 5. The golf ball of claim 1 , wherein the outer surface of the golf ball comprises 390 dimples. 6. The golf ball of claim 1 , wherein the outer surface of the golf ball comprises 320 dimples. 7. The golf ball of claim 1 , wherein the outer surface of the golf ball comprises 302 dimples. 8. The golf ball of claim 1 , wherein the outer surface of the golf ball comprises 432 dimples.
