Golf Club Head Face Height and Center of Gravity Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Golf club heads face challenges in balancing performance characteristics, such as face height and center of gravity location, which can lead to unintended performance consequences when adjusting features like the strikeface size, affecting impact area, energy transfer, launch angle, and backspin.
Innovation Solution
The golf club head design optimizes characteristics by configuring the face height, center of gravity location, and moments of inertia to satisfy specific ratios and ranges, ensuring balanced performance, including a face height of 33 mm to 71 mm, CG height ≤ 5.08 mm, CG performance ratio ≤ 0.56, head volume ≥ 420 cc, and moments of inertia relationships, to enhance forgiveness and energy transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the strikeface of a golf club is expanded to provide a greater impact area, then the impact area is improved, but the location of the center of gravity is altered disadvantageously
Solution Approach 1:
The patent applies parameter changes by precisely controlling the face height parameter (33-71 mm) and center of gravity location parameters (CG height ≤ 5.08 mm, CG performance ratio ≤ 0.56) to achieve the desired balance between impact area and center of gravity location, resolving the technical contradiction through quantitative optimization
2Reliability
If features of the golf club are configured to improve one performance characteristic, then that characteristic is improved, but other performance characteristics may be adversely affected
Solution Approach 1:
The patent simultaneously optimizes multiple parameters including face height (33-71 mm), head volume (≥ 420 cc), CG height (≤ 5.08 mm), and CG performance ratio (≤ 0.56) to achieve balanced performance across multiple characteristics including forgiveness, energy transfer, and shot distance, preventing adverse effects on any single characteristic
3Reliability
If the face height is increased to provide more forgiveness, then forgiveness is improved, but the center of gravity location and moments of inertia are adversely affected
Solution Approach 1:
The patent optimizes face height within the range of 33-71 mm while simultaneously controlling CG height (≤ 5.08 mm) and CG performance ratio (≤ 0.56) to achieve the desired balance between forgiveness and stability of center of gravity location and moments of inertia
