Golf Club Head Deflector for Face Stiffness and Ball Speed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Golf club heads often struggle with inconsistency in hitting the ball squarely, leading to issues with launch angle, speed, and spin, particularly when hitting 'down' on the ball.
Innovation Solution
The golf club head design incorporates a deflector at the head wave section, which allows for increased face deflection upon impact, reducing sole stiffness and enhancing energy transfer for improved ball speed and launch characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the strikeplate is made thinner to reduce weight and improve flexibility, then ball speed and energy transfer are improved, but structural integrity and strength are compromised
Solution Approach 1:
The strikeplate is divided into multiple regions with different thicknesses - a thinner region for flexibility and energy transfer, and a thicker region for structural strength. This segmentation allows each region to perform its specific function optimally without compromising the other.
Solution Approach 2:
Different portions of the strikeplate have different local properties - the face portion is thinner to enhance ball speed and energy transfer, while the rear portion is thicker to maintain structural integrity. This local differentiation resolves the contradiction between flexibility and strength.
2Speed
If the sole stiffness is reduced to increase face deflection, then energy transfer and ball speed are improved, but impact stress dissipation may be compromised
Solution Approach 1:
The sole incorporates dynamic elements that allow controlled deflection during impact - the face portion can deflect to transfer energy efficiently, while the rear portion maintains stiffness to dissipate impact stresses. This dynamic response resolves the contradiction between flexibility and stress management.
Solution Approach 2:
The sole's stiffness parameter is varied across different regions - lower stiffness in the face area for energy transfer and higher stiffness in the rear area for stress dissipation. This parameter differentiation allows the sole to simultaneously achieve both improved ball speed and impact stress management.
3Use of energy by moving object
If face deflection is increased to improve energy transfer, then ball speed and launch characteristics are improved, but consistency in hitting the ball squarely may worsen
Solution Approach 1:
The face is designed with localized deflection characteristics - high deflection in specific regions for energy transfer, and controlled deflection in other regions to maintain consistency. This local differentiation allows the face to be both flexible for energy transfer and consistent for reliable ball contact.
Solution Approach 2:
The face is segmented into regions with different deflection properties, allowing certain areas to deflect more for energy transfer while other areas maintain stability for consistent ball contact. This segmentation resolves the contradiction between energy transfer and hitting consistency.
