Golf Club Head Density Layout for Higher MOI Without Weight Ports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current golf club head designs face challenges in uniformly distributing weight to optimize center of gravity positions and increase club head moment of inertia, often requiring complex manufacturing processes and affecting aerodynamics due to the use of weight ports or inserts.
Innovation Solution
A golf club head design featuring a high density body and a low density face, with a specific gravity ratio greater than or equal to 1.7, positions the center of gravity closer to the bottom, maximizing weight distribution away from the center and increasing moment of inertia, thereby simplifying manufacturing and improving performance characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If weight ports or inserts are used to optimize center of gravity position and increase moment of inertia, then club head performance is improved, but manufacturing complexity increases and aerodynamics are affected
Solution Approach 1:
The patent changes the density parameter of the club head material to achieve weight optimization. By using a high density material (specific gravity ≥1.7) for the entire club head body, the invention achieves proper center of gravity positioning and increased moment of inertia without requiring additional weight ports or inserts, thus simplifying manufacturing while maintaining performance
Solution Approach 2:
The patent applies local quality by using a high density material specifically for the club head body while keeping the face material separate. This localized application of high density material in the body portion achieves the desired weight distribution and performance characteristics without affecting other parts of the club head
2Weight of moving object
