Golf Club Head Face Damping for Uniform Ball Speed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional golf clubs exhibit non-uniform ball speeds across the striking face due to varying deflection, leading to significant distance variations and reduced performance on off-center strikes, while also lacking consistent sound production.
Innovation Solution
Incorporation of a damping element between the striking face and the rear surface of the golf club head, which reduces deflection at the center and enhances uniformity of ball speeds across the striking face, using materials with adjustable elastic moduli to meet specific performance needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the striking face is made thin to reduce weight and increase ball speed, then ball speed is improved, but deflection becomes non-uniform across the face leading to inconsistent ball speeds on off-center strikes
Solution Approach 1:
The patent applies local quality by varying the thickness of the striking face across different regions. The center portion is thinner to maximize ball speed on center strikes, while the peripheral portions are thicker to reduce deflection on off-center strikes. This spatial variation in thickness creates different local properties that optimize performance for different impact locations.
Solution Approach 2:
The patent introduces a thickness dimension to the striking face design, transitioning from a uniform thin face to a face with variable thickness in the depth direction. This dimensional change allows the face to have different effective thicknesses at different locations, resolving the contradiction between speed and uniformity.
2Stability of the object's composition
If the striking face is made thick to reduce deflection and improve uniformity, then uniformity of ball speeds is improved, but ball speed decreases
Solution Approach 1:
The striking face is designed with non-uniform thickness where the center region is thinner to maintain high ball speed on center strikes, while the peripheral regions are thicker to provide structural support and reduce deflection on off-center strikes. This local differentiation resolves the contradiction between speed and uniformity.
3Stability of the object's composition
If damping material is added to the cavity to reduce deflection and improve uniformity, then uniformity of ball speeds is improved, but the complexity of the club head increases
Solution Approach 1:
The patent changes the physical parameters of the striking face by varying its thickness across different regions. This parameter change in the face geometry itself provides the deflection control and uniformity improvement without requiring additional damping materials or complex internal structures, thus avoiding increased device complexity.
