Abstract
Various aspects of a dimple pattern methodology, and dimple pattern configurations are disclosed herein. A spherical quadrilateral segment division can be used to maintain a high level of symmetry in the dimple pattern while also maintaining a specific dimple layout in polar regions of the golf ball. In one aspect, the specific configurations disclosed herein can provide geometric symmetry while being adaptable to relatively complex processes for forming golf ball covers. Furthermore, the configurations disclosed herein provide a dimple pattern with a high level of symmetry having a particular subset of preferred polar dimples.

A golf ball having an outer surface comprising a plurality of dimples disposed thereon that define a dimple pattern,
- the golf ball being segmented into a first hemisphere and a second hemisphere, each of the first and second hemispheres being defined by a plurality of zones, and each zone being segmented into a plurality of spherical quadrilaterals each having a distinct dimple configuration,
- wherein the dimple pattern has at most second order rotational symmetry about any axis of the golf ball, and
- wherein the first and second hemispheres each include a subset of preferred polar dimples having:
- (i) an identical dimple diameter,
- (ii) a respective centroid positioned longitudinally 90 degrees apart from each other, and
- (iii) a respective centroid positioned at a common latitude,
- wherein the common latitude is defined at a polar latitude angle (θ) from a nearest respective pole of the first and second hemispheres, and the polar latitude angle (θ) is no greater than 30 degrees.
