Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional golf club faces do not optimize ball exit speeds and performance across the striking surface, leading to inconsistent distance and control.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional uniform thickness faceplates are used, then manufacturing is simpler, but ball exit speeds and performance are inconsistent across the striking surface
Solution Approach 1:
The faceplate employs variable thickness design where different regions have different wall thicknesses optimized for their specific functions. The center region has greater thickness for maximum ball exit speed, while peripheral regions have reduced thickness for optimal performance at those locations. This local differentiation resolves the contradiction by achieving performance consistency through localized optimization rather than uniform construction.
Solution Approach 2:
The patent changes the geometric parameter of wall thickness from a uniform value to a continuously varying profile. By systematically varying the thickness parameter across the faceplate surface according to a optimized profile, the design achieves consistent ball exit speeds across different impact locations while maintaining manufacturing feasibility through modern fabrication capabilities.
2Speed
If maximum faceplate thickness is placed at central location, then ball exit speed is maximized, but weight distribution and structural response must be carefully controlled
Solution Approach 1:
The faceplate design places maximum thickness at the central location to maximize ball exit speed for center hits, while gradually reducing thickness toward the periphery. This local quality differentiation ensures that structural strength is concentrated where it provides maximum benefit (center impact) while reducing weight and optimizing structural response in peripheral regions where maximum strength is not critical.
Solution Approach 2:
The variable thickness profile creates a dynamic structural response during impact. The thicker central region provides maximum stiffness and energy return for center hits, while the thinner peripheral regions allow for controlled deformation and energy dissipation on off-center impacts. This dynamic adaptation of structural properties optimizes both ball exit speed and overall structural performance.
3Power
If variable thickness profile with closed non-convex contour curves is implemented, then kinetic response is enhanced, but manufacturing complexity increases
Solution Approach 1:
The patent implements a continuously variable thickness profile defined by closed non-convex contour curves that optimize kinetic response. By systematically varying the thickness parameter according to a mathematically defined profile rather than using discrete steps or simple geometric forms, the design achieves enhanced power and kinetic response while maintaining manufacturability through modern additive manufacturing or precision machining capabilities.

AI summary
A golf club may include a head having a body and a faceplate coupled to the body. The faceplate may have a maximum thickness at a central location and a cross-section intersecting the central location. The cross-section may have continuously variable wall thickness across the faceplate. The faceplate may have a closed non-convex contour curve defined by constant faceplate wall thickness that encloses the central location.
