Golf Club Head with Inflection Point for Energy Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Golf club heads lack designs that allow for flexing in the crown to sole direction and do not effectively store additional spring energy upon impact with the golf ball, limiting ball speed and distance control.
Innovation Solution
The golf club head features a cascading sole with tiered internal thin sections and a back cavity design, which includes a crown internal radius transition and a hollow body with a top rail and cavity, allowing for increased bending and energy storage upon impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the golf club head is designed with a rigid structure to relieve stress in the strikeface, then durability is improved, but the ability to flex in the crown to sole direction is lost and spring energy storage is reduced
Solution Approach 1:
The patent applies local quality by creating a crown internal radius transition region that concentrates flexibility in the crown area while maintaining overall structural integrity. This localized geometric transition allows the crown to flex independently in the crown-to-sole direction without compromising the strength of the entire club head, enabling spring energy storage while preserving durability.
2Ease of manufacture
If the golf club head uses traditional stress relief designs, then manufacturing simplicity is maintained, but the ability to store additional spring energy upon impact is limited
Solution Approach 1:
The patent employs parameter changes by modifying the internal radius of the crown region to create a transition zone. This geometric parameter change enables the crown to flex and store spring energy upon ball impact, while the overall design remains compatible with traditional manufacturing processes, maintaining ease of manufacture without requiring complex additional structures.
3Manufacturing precision
If the golf club head maintains a uniform thickness design, then manufacturing precision is simplified, but ball speed and energy storage are limited
Solution Approach 1:
The patent applies segmentation by dividing the crown region into different thickness zones through the internal radius transition. This creates distinct functional areas: a thinner transition region that flexes to store energy and a thicker outer crown that maintains structural strength. The segmented design enhances ball speed through improved energy storage while remaining manufacturable with standard precision tolerances.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enhances ball speed by 0.5-1.5 mph, increases launch angle, decreases spin, and improves carry distance by 3-6 yards, while maintaining durability and stress distribution across a larger area.
Implementation Method 1
Additional spring energy can increase ball speed across the strikeface
Implementation Method 2
do not allow additional storage of spring energy in the golf club head due to impact with the golf ball

AI summary
Embodiments of golf club heads with energy storage characteristics are presented herein. In some embodiments, a golf club head comprises a hollow body comprising a strikeface, a heel region, a toe region opposite the heel region, a sole, a top rail and an inflection point. The inflection point provides increase bending of the strikeface thereby providing performance enhancement over clubs without an inflection point.
