Golf Club Face Damping Structure for Ball Speed Consistency

The patent applies local quality by varying the thickness of the striking face across different regions. The striking face is thinner at the center (geometric center) to maximize ball speed for center hits, while being thicker toward the periphery (heel and toe regions) to reduce deflection variability for off-center hits. This spatial variation in thickness creates local differences in face compliance that optimize both center and off-center shot performance, resolving the contradiction between ball speed and ball speed consistency.

The patent resolves this contradiction by implementing local quality through non-uniform face thickness distribution. Rather than making the entire face uniformly thick, the design creates a gradient where the center region remains thin for high ball speed while peripheral regions are thicker for consistency. This localized differentiation allows each region to fulfill its specific function optimally.

The patent addresses the sound quality issue through local quality by creating regions of different stiffness. The thicker peripheral regions provide structural rigidity that generates a more pleasing sound upon impact, while the thinner center region maintains high ball speed. This spatial differentiation in mechanical properties allows the club to produce desirable acoustic characteristics without sacrificing performance.
