Golf Club Head Weight Distribution for Launch Angle Control
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 distribute weight to enhance launch angle and reduce spin rate.
Innovation Solution
The golf club head incorporates multiple sets of weight portions made from different materials, such as steel-based and tungsten-based materials, strategically positioned to optimize CG and MOI, with the use of exterior weight ports and an interior cavity to lower CG and increase MOI, thereby enhancing launch angle and reducing spin rate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple materials are used to manufacture golf club heads, then the center of gravity and moment of inertia can be optimized, but the device complexity increases
Solution Approach 1:
The golf club head is divided into multiple distinct weight portions made from different materials (steel, tungsten, titanium) that can be independently positioned within the club head structure. This segmentation allows precise control over the center of gravity location and moment of inertia distribution, resolving the contradiction by enabling CG optimization through material segmentation rather than using a single complex multi-material construction throughout the entire club head.
Solution Approach 2:
Different materials with specific densities are selectively placed in specific regions of the golf club head to achieve desired weight distribution. High-density tungsten is placed in certain areas while lighter steel or titanium is used in other regions, allowing local optimization of the center of gravity position and moment of inertia characteristics without requiring the entire club head to be complex multi-material construction.
2Manufacturing precision
If weight portions are strategically positioned to optimize CG and MOI, then launch angle increases, but the manufacturing process becomes more complex
Solution Approach 1:
The weight portions are pre-positioned and secured within the golf club head during the manufacturing process before final assembly. This preliminary positioning ensures that the center of gravity and moment of inertia are optimized from the outset, achieving the desired launch angle and trajectory characteristics without requiring complex post-manufacturing adjustments or adjustments that would increase manufacturing complexity.
Solution Approach 2:
Multiple weight portions made from different materials are nested or integrated within the golf club head structure, with each weight portion serving a specific function in the overall weight distribution scheme. This nesting approach allows complex weight distribution patterns to be achieved through layered or integrated placement of simpler components, reducing overall manufacturing complexity while maintaining precise CG and MOI control.
3Manufacturing precision
If exterior weight ports and interior cavity are used to lower CG, then spin rate decreases, but the structural complexity increases
Solution Approach 1:
The golf club head structure incorporates both exterior weight ports and an interior cavity, utilizing three-dimensional spatial arrangement to position weight portions. This multi-dimensional weight distribution approach lowers the center of gravity and optimizes moment of inertia to control spin rate, while the structured use of standard structural elements (ports and cavities) keeps the complexity manageable through systematic design rather than arbitrary complex structures.
