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 (9)

1. A golf ball having an outer surface comprising a real parting line, one or more false parting line(s), and a plurality of dimples, wherein the dimples are arranged in multiple copies of a first domain and a second domain covering the outer surface of the golf ball in a uniform pattern, wherein the first domain has three-way rotational symmetry about the central point of the first domain and the second domain has five-way rotational symmetry about the central point of the second domain, wherein the real parting line and the one or more false parting line(s) are non-straight, and wherein there is no great circle on the outer surface of the golf ball that does not intersect any of the dimples.

2. The golf ball of claim 1 , wherein the outer surface of the golf ball comprises 332 dimples.

3. The golf ball of claim 1 , wherein the outer surface of the golf ball comprises 392 dimples.

4. The golf ball of claim 1 , wherein the outer surface of the golf ball comprises 432 dimples.

5. The golf ball of claim 1 , wherein the outer surface of the golf ball comprises 252 dimples.

6. The golf ball of claim 1 , wherein the outer surface of the golf ball comprises 372 dimples.

7. The golf ball of claim 1 , wherein the outer surface of the golf ball comprises 362 dimples.

8. The golf ball of claim 1 , wherein the outer surface of the golf ball comprises 272 dimples.

9. The golf ball of claim 1 , wherein the outer surface of the golf ball comprises 312 dimples.
