Golf Club Head Damping Layout for Uniform Face Ball Speed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional golf clubs exhibit non-uniform ball speeds and distances due to varying compliance across the striking face, leading to significant losses in flight distance for off-center strikes and reduced overall distance for center strikes.
Innovation Solution
Incorporation of a damping element between the striking face and the rear surface of the golf club head, positioned to reduce deflection at the geometric center while maintaining uniformity of launch velocities across the striking face.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the striking face is made thin to increase ball speed at center strikes, then ball speed at center strikes is improved, but uniformity of ball speed across the striking face deteriorates
Solution Approach 1:
The patent applies local quality by placing a damping element specifically at the geometric center of the striking face, where compliance is highest. This localized intervention reduces deflection only at the center region, allowing the rest of the face to maintain its thin, high-speed characteristics while achieving uniform ball speed distribution across the entire face.
2Stability of the object's composition
If the striking face is made thick to improve uniformity of ball speed, then uniformity of ball speed across the striking face is improved, but ball speed at center strikes deteriorates
Solution Approach 1:
The patent changes the physical parameter of the striking face by introducing a damping element that modifies the local compliance characteristics. The damping element has specific material properties (density, damping coefficient) that are optimized to reduce center-face deflection without significantly altering the overall face thickness, thereby maintaining high ball speeds while improving uniformity.
3Stability of the object's composition
If a damping element is added to the cavity to reduce center face deflection, then uniformity of ball speed is improved, but device complexity increases
Solution Approach 1:
The damping element is nested within the existing cavity of the club head structure, utilizing the available internal space efficiently. This nesting approach allows the damping element to be integrated into the design without adding external complexity or significantly increasing the overall club head volume, thereby minimizing the impact on device complexity.
4Stability of the object's composition
If the damping element is positioned at the geometric center of the striking face, then uniformity of launch velocities is improved, but manufacturing precision requirements increase
Solution Approach 1:
The damping element is designed with an asymmetric shape that is intentionally mismatched to the cavity geometry. This asymmetric design creates a unique fit that allows the element to be positioned correctly through simple insertion, eliminating the need for precise alignment during manufacturing. The asymmetry ensures that only one orientation fits properly, simplifying the assembly process while maintaining the desired center-face positioning.
