Golf ball dimple patterns with multiple phyllotactic elements
View Patent ↗A golf ball is disclosed having a plurality of dimples on its surface, the dimples being arranged in patterns determined by the science of phyllotaxis. Phyllotactic patterns are used to ascertain the placement of dimples in each polygonal face of a polyhedron based dimple pattern. Phyllotactic patterns provide for the arrangement of multiple spiral shaped strings of dimples within individual polygonal faces of a golf ball surface, with each polygonal face area having its own phyllotactic origination point at its center. The resulting multiple axes of symmetry in the overall dimple pattern provide improved symmetry of flight performance.

an outer surface having a plurality of spherical polygonal regions;
multiple strings of dimples arranged in phyllotactic patterns within each polygonal region;
each polygonal region having its own phyllotactic origination point; and
the polygonal regions comprising a dodecahedron based dimple pattern and the polygonal regions being of a pentagon shape, each pentagon having a common dimple and five spirally shaped arms of dimples,
wherein the overall dimple pattern has more than one axis of symmetry.
2. The golf ball of claim 1 , wherein the origination point is at the geometric center of the polygonal region.
3. The golf ball of claim 1 , wherein substantially all of the dimples are defined by the phyllotactic patterns.
