Golf Club Damping Element for Ball Speed Uniformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional thin-faced iron-type golf clubs experience non-uniform ball speed across the striking face due to increased compliance at the geometric center, leading to significant losses in flight distance with off-center strikes, while extremely thick faces result in uniform ball flight but reduced launch velocities.
Innovation Solution
Incorporating an elastomer element between the back portion of the hollow iron and the rear surface of the striking face, which reduces deflection at the center and improves uniformity of launch velocities across the face, with adjustable compression to optimize performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the striking face is made thin to increase launch velocity, then the center compliance increases causing non-uniform ball speed, but making it thick provides uniform ball flight at the cost of reduced launch velocity
Solution Approach 1:
The striking face is designed with non-uniform thickness distribution, featuring a thinner central region for higher launch velocity and thicker peripheral regions for stability. This local variation in geometric properties allows the face to simultaneously achieve high launch velocity at impact center while maintaining uniform ball speed across different strike locations.
Solution Approach 2:
The club head incorporates multiple materials with different mechanical properties, including metallic alloys for the main structure and potentially composite materials in specific regions. This composite construction allows optimization of both stiffness and flexibility in different areas, enabling the striking face to provide both high launch velocity and uniform ball speed characteristics.
2Speed
If the striking face is made thin to reduce weight and increase compliance for higher ball speed, then off-center strikes result in significant distance loss, but making it thick provides durability at the cost of reduced ball speed
Solution Approach 1:
The striking face employs localized thickness variation with a thinner central zone optimized for high ball speed and thicker peripheral zones that provide structural support and consistency. This local differentiation allows the face to maintain high performance across the sweet spot while ensuring reliable and consistent results even on slightly off-center strikes.
Solution Approach 2:
The striking face design incorporates dynamic flexibility through its thickness profile, allowing controlled deflection and recovery. The thinner central region provides the necessary compliance for efficient energy transfer and high ball speed, while the overall face structure maintains sufficient rigidity to ensure consistent performance across varying impact conditions.
3Use of energy by moving object
If the striking face is made thin to improve energy transfer, then stress concentrations increase reducing club face durability, but making it thick reduces stress at the cost of energy transfer efficiency
Solution Approach 1:
The striking face features localized thickness optimization where the thinner central region maximizes energy transfer efficiency during impact, while thicker peripheral regions provide structural strength and distribute stresses. This local quality differentiation allows the club face to simultaneously achieve high energy transfer and adequate durability.
Solution Approach 2:
The club head utilizes composite material construction with different material properties in different regions. The striking face may incorporate materials or structures that optimize the balance between flexibility for energy transfer and strength for durability, allowing efficient energy transfer without excessive stress concentrations that would compromise longevity.
