Chromogenic polymers in golf ball cover or coating layers create stimulus-driven color shifts for identification, alignment, and swing feedback.
Modified cycloid dimple profiles decouple diameter from chord depth to expand golf-ball geometry options and reduce drag for steadier flight.
Traditional geometric layouts can limit golf ball surface coverage; irregular polyhedral domains vary dimple diameters to improve lift and drag.
A layered golf ball tunes core and cover hardness, cover thickness, and dimple volume to narrow flight-distance differences across head speeds.
A staged Shore C hardness profile across the spherical core balances driver-shot distance with middle-iron spin.
Shore D hardness, cover thickness, and dimple volume balance high spin with limited lift and controlled flight height.
Segmented spherical triangles preserve dimple symmetry during complex cover formation for more consistent golf-ball flight.
Zoned dimple layouts balance local configurations with geometric symmetry to support stable golf ball assembly during complex cover formation.
Segmented spherical quadrilateral zones preserve dimple symmetry while supporting stable golf ball covers formed by RIM and RPIM.
Limited core hardness gradients can restrict spin reduction; a water-releasing agent during curing helps maintain durability as the outer core becomes harder.
Sharp traditional dimple profiles can increase drag; smooth piecewise curves help preserve lift and extend golf ball flight.
