Will golf ball dimples soon be a thing of the past? If you look at this patent recently awarded to Acushnet (owner of Titleist), it looks like dimples are on their way out! Once again, thank you to
The IP Golf Guy for the heavy lifting on this one. Can you imagine playing a ball with one of the covers below? Seems very foreign. The following excerpt is from the patent application, titled “Golf Ball Surface Textures:”
Over the years, golf ball’s have evolved to include dimpled surfaces. The dimpled surfaces are typically used to reduce drag, thereby increasing the distance a golf ball is capable of flying. Although round dimples are used by most manufacturers, other shapes such as hexagonal, square, oval, and the like have been experimented with. The dimple depth, shape, and even the number of dimples have been modified in an attempt to reduce the drag on the golf ball as much as possible.
Manipulation of dimples, however, may eventually reach a point beyond which drag cannot be reduced further. Accordingly, other methods of reducing drag or increasing lift may be useful. The present invention provides a method for altering the texture of the surface of a golf ball that is capable of reducing drag on a golf ball during flight. The present invention is capable of achieving the reduction in drag by generating a golf ball surface texture based on sweeping shaped profiles across predetermined guide patterns on the ball’s spherical surface. Preferably, the reduction in drag may be achieved without using conventional dimples. However, it may be desirable to include protrusions or entrenchments on the surface of the golf ball after the shaped profiles have been swept across the predetermined guide patterns.
According to one aspect of the present invention, the shaped profiles and the predetermined guide patterns may be generated using a processor based computer program or the like. It may be desirable for the processor to be capable of executing computer program instructions. In one embodiment, the processor may be operatively connected to, for example, a memory, user interface, display, and the like. Preferably, the processor is capable of running an operating system that supports a computer program that is capable of simulating the effect of dragging a plurality of different shaped profiles across different paths. It may be desirable for the processor to be capable of determining the drag that would result from different combinations of shaped profiles and guide patterns such that a golf ball manufacturer could use this calculation to choose combinations that result in optimal golf ball surfaces.
In one embodiment, the present invention comprises a method for forming a golf ball surface texture that reduces drag. Preferably, the method includes determining a guide pattern to be mapped to the spherical surface of the ball. The guide pattern may have any desired shape. This may include, but is not limited to, geometric patterns, fractal patterns, irregular patterns, lines, and the like. In one embodiment, it may be desirable for the pattern to be a combination of at least two of geometric patterns, fractal patterns, irregular patterns, and lines.
