Golf Club Head Weight Distribution via Multi-Material Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current golf club head designs face challenges in optimizing the center of gravity (CG) and moment of inertia (MOI) to achieve desired trajectory and spin rates, as they often rely on single material compositions that limit weight distribution and aerodynamics.
Innovation Solution
The use of multiple materials, such as steel-based, titanium-based, and tungsten-based materials, in combination with advanced manufacturing techniques like investment casting and CNC machining, to create a golf club head with optimized weight distribution and aerodynamic design, featuring multiple weight portions strategically placed to adjust the CG and MOI.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If single material composition is used to manufacture golf club head, then manufacturing process is simple, but weight distribution and aerodynamics cannot be optimized
Solution Approach 1:
The patent employs multiple materials including steel-based materials, titanium-based materials, and tungsten-based materials to manufacture different portions of the golf club head. This composite material approach enables optimized weight distribution and center of gravity positioning while maintaining manufacturing feasibility through established multi-material joining techniques
Solution Approach 2:
The golf club head is divided into multiple portions manufactured from different materials - the body portion from steel-based material and weight portions from tungsten-based or titanium-based materials. This segmentation allows independent optimization of each portion's material properties to achieve desired overall performance characteristics
2Manufacturing precision
If multiple materials are used to optimize weight distribution, then center of gravity and moment of inertia are improved, but manufacturing complexity increases
Solution Approach 1:
The patent optimizes specific parameters including the position, mass, and material composition of weight portions to precisely control the center of gravity and moment of inertia. By adjusting these parameters within defined ranges, the patent achieves targeted performance optimization while managing manufacturing complexity through systematic parameter control
3Ease of manufacture
If traditional manufacturing methods are used, then production is straightforward, but aerodynamic optimization is limited
Solution Approach 1:
The patent incorporates aerodynamic considerations into the golf club head design by optimizing the shape and contours of the body portion to reduce air resistance during the swing. This dynamic aerodynamic optimization works in conjunction with traditional manufacturing methods to achieve both performance improvement and manufacturing feasibility

AI summary
Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a method of manufacturing a golf club head includes forming a body portion with an interior cavity, forming a face portion, attaching the face portion to the body portion to close the interior cavity, injecting a polymer material into the interior cavity from a port on the body portion, and inserting a first mass portion into the port to close the port. The method further includes attaching a second mass portion to the body portion below a horizontal midplane of the body portion. A total mass of the second mass portion may be greater than or equal to five times a total mass of the first mass portion. Other examples and embodiments may be described and claimed.
