Golf Club Head Tungsten Mass Portion CG Optimization
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 existing materials and manufacturing methods do not effectively balance weight distribution and structural integrity.
Innovation Solution
The design incorporates a golf club head with a body portion made from steel-based or titanium-based materials, featuring multiple mass portions made from tungsten-based materials or other high-density materials, strategically positioned to optimize CG and MOI through various manufacturing processes such as bonding, welding, or mechanical locking, and filled with a polymer material to enhance structural support and vibration damping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple materials are used to manufacture golf club heads, then the position of the center of gravity and moment of inertia can be optimized, but the manufacturing complexity and structural integrity become more difficult to control
Solution Approach 1:
The patent employs multiple materials including steel-based materials, titanium-based materials, and tungsten-based materials to create a composite golf club head structure. This allows optimization of the center of gravity position and moment of inertia by strategically placing high-density tungsten mass portions while maintaining structural integrity through the strength of steel and titanium components.
Solution Approach 2:
The patent applies different materials to specific regions of the golf club head based on local requirements. High-density tungsten is concentrated in specific mass portions to adjust CG position, while steel and titanium are used in structural areas requiring strength and lightweight properties. This localized material distribution optimizes performance parameters without uniformly increasing manufacturing complexity.
2Manufacturing precision
If high-density materials like tungsten are used to optimize weight distribution, then CG and MOI are improved, but the manufacturing precision and structural integration become more challenging
Solution Approach 1:
The patent divides the golf club head into multiple discrete components or mass portions, each made from specific materials. The tungsten-based mass portions are separated from the steel and titanium structural components, allowing each part to be manufactured and optimized independently before assembly. This segmentation makes it easier to control the weight distribution and CG position while maintaining structural integrity through precise assembly.
Solution Approach 2:
The patent utilizes the high density parameter of tungsten material to achieve precise weight distribution and CG positioning. By changing the material parameter (density) in specific regions rather than uniformly throughout the club head, the design optimizes weight distribution without requiring complex manufacturing processes. The density difference between tungsten and other materials allows for precise control of mass placement.
