Golf Club Head Forward Hosel Axis and Toe Mass Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Golf clubs often result in short and high miss hits, leading to inefficient ball trajectory due to inadequate moment of inertia and mass distribution, causing excessive twisting and spin during off-center hits.
Innovation Solution
A golf club head design with a wider toe and strategically positioned center of gravity, characterized by specific ratios of moment of inertia to mass and volume, and a forwardly offset hosel axis, which enhances the launch angle and reduces spin, resulting in longer and straighter shots.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the golf club head uses conventional mass distribution, then the club head is easier to manufacture, but the moment of inertia is insufficient causing excessive twisting and spin during off-center hits
Solution Approach 1:
The patent changes the mass distribution parameters by positioning the center of gravity forward and lowering it, and by increasing the toe width. These parameter changes increase the moment of inertia without requiring complex structural modifications, resolving the contradiction between strength and complexity.
Solution Approach 2:
The patent employs asymmetric mass distribution by deliberately offsetting the center of gravity from the geometric center, positioning it forward and downward. This asymmetric configuration optimizes the moment of inertia for reducing twisting during off-center hits while maintaining manufacturability through straightforward casting or molding processes.
2Speed
If the hosel axis is positioned traditionally, then the manufacturing process is simpler, but the launch angle is insufficient and spin is excessive
Solution Approach 1:
The patent changes the hosel axis position parameter by moving it forward and lowering it relative to the center of gravity. This parameter change optimizes the launch angle and reduces spin while remaining compatible with conventional manufacturing methods, as the hosel can still be integrated using standard casting or molding techniques.
3Strength
If the toe width is increased, then the moment of inertia increases reducing twisting, but the club head volume increases
Solution Approach 1:
The patent applies local quality by increasing only the toe width while maintaining other dimensions within acceptable limits. This localized modification optimizes the moment of inertia specifically for reducing twisting during off-center hits, while the overall volume increase is minimized through precise dimensional control in the toe region only.
