Patent number: 10668334Abstract: Golf balls and golf ball components made using three-dimensional (3D) additive manufacturing systems are provided. The golf ball includes at least one three-dimensional piece. Preferably, a continuous liquid interface printing method is used to make the three-dimensional structure. Ultraviolet (UV)-light polymerizable materials are used in the method. The method may be used to make single-piece or multi-piece balls. For example, the ball may include an inner core produced by the liquid interface printing method. An outer core layer may be disposed about the inner core, and a cover comprising inner and outer cover layers may encapsulate the core assembly to form the finished golf ball. The outer core and cover layers may be made using conventional molding technologies or the methods of this invention.Type: GrantFiled: July 9, 2018Date of Patent: June 2, 2020Assignee: Acushnet CompanyInventors: Michael R. Madson, Edmund A. Hebert, Nicholas M. Nardacci, Brian Comeau

Publication number: 20200155899Abstract: Systems and methods for identifying golf equipment. The system may include one or more performance tracking devices, such as an optical sensor system or a radar sensor system for tracking at least one of a golf club swing or a golf ball flight. The system also may include at least one processor and memory storing instructions that, when executed by the at least one processor, cause the system to perform a set of operations. The operations include receiving current dynamic input for a golf shot from a golfer and current static input for the golfer. The operations also include executing a trained machine-learning model based on the received current dynamic input and current static input to generate predicted golf club properties and/or predicted golf ball properties for the golfer. The predicted golf club properties and/or predicted golf ball properties are displayed on a connected display.Type: ApplicationFiled: November 16, 2018Publication date: May 21, 2020Applicant: Acushnet CompanyInventors: Chris Hixenbaugh, Nicholas M.

Patent number: 10653920Abstract: The present invention is directed to golf balls having improved aerodynamic performance due, at least in part, to the alteration of the dimple surfaces. In particular, the present invention relates to a golf ball that includes at least a portion of its dimples having circular perimeters and dimple profiles having a concentric groove or a non-concentric groove on the surface of the dimple. The golf ball dimples of the present invention provide golf ball surfaces having unique appearances, while maintaining ideal aerodynamic characteristics.Type: GrantFiled: December 3, 2018Date of Patent: May 19, 2020Assignee: Acushnet CompanyInventors: Michael R.

Patent number: 10653921Abstract: 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.Type: GrantFiled: September 1, 2019Date of Patent: May 19, 2020Assignee: Acushnet CompanyInventors: Michael R.

Publication number: 20200061419Abstract: Golf balls including at least one modified dimple group are disclosed. The modified dimple group comprises one or more modified dimples forming an axially symmetric pattern about a Correction Area Centroid located on an axis of symmetry at a latitude greater than 0°, where 0° represents the hemispherical pole and 90° represents the equator. The modified dimples can be altered, for example, by changing dimple coverage, dimple diameter, dimple depth, dimple edge angle, dimple volume, dimple cross-sectional shape, and/or dimple plan shape. Optionally, the dimples have a catenary cross-sectional shape and the modified dimples are altered by changing the shape factor and/or chord depth. Such modifications preferably produce a golf ball that flies more consistently regardless of orientation when struck than a corresponding golf ball without such modifications.Type: ApplicationFiled: November 4, 2019Publication date: February 27, 2020Applicant: Acushnet CompanyInventors: Michael R.

Publication number: 20200061418Abstract: The present invention concerns a golf ball having dimples with a cross-sectional profile comprising a conical top portion and a bottom portion. More particularly, the profiles of the present invention are defined by three independent parameters: dimple diameter (DD), edge angle (?EDGE), and saucer ratio (Sr). These parameters fully define the dimple shape and allow for greater flexibility in constructing a dimple profile versus conventional spherical dimples. The dimples optionally have a transition surface connecting the conical top portion to the land area of the golf ball and/or a transition surface connecting the conical top portion to the bottom portion.Type: ApplicationFiled: November 4, 2019Publication date: February 27, 2020Applicant: Acushnet CompanyInventors: Michael R.
