Golf Club Head Weight Optimization via Segmented Materials
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current golf club head designs fail to optimize the center of gravity (CG) and moment of inertia (MOI) effectively, leading to suboptimal ball trajectory and spin rates.
Innovation Solution
The golf club head incorporates multiple weight portions made of different materials, such as tungsten-based and steel-based materials, strategically positioned to optimize the CG and MOI, with a hollow body and interior cavity filled with elastic polymers to enhance structural integrity and performance.
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 material regions, including a titanium-based material body, stainless steel weight portions, and tungsten-based material inserts. Each segment serves a specific function: the titanium body provides lightweight structural integrity, the stainless steel portions adjust center of gravity position, and the tungsten inserts maximize moment of inertia. This segmentation allows independent optimization of each material's contribution to overall performance.
Solution Approach 2:
The golf club head employs a composite construction combining four different materials: titanium-based material for the main body, stainless steel for weight portions, tungsten-based material for high-density inserts, and elastomer for vibration damping. This multi-material composite approach enables simultaneous optimization of weight distribution, structural strength, center of gravity location, and vibration characteristics that cannot be achieved with a single material.
2Manufacturing precision
If weight portions are strategically positioned to optimize CG and MOI, then ball trajectory and spin rate improve, but the manufacturing process becomes more complex
Solution Approach 1:
The weight portions are pre-positioned within the club head body during the manufacturing process rather than being adjusted after assembly. The titanium-based material body is formed with predetermined cavities and recesses that accommodate specific weight portions at optimized locations. This preliminary positioning ensures precise center of gravity and moment of inertia characteristics are achieved during manufacturing, eliminating the need for complex post-assembly adjustments.
3Strength
If a hollow body with interior cavity is used, then structural integrity is enhanced, but the device complexity increases
Solution Approach 1:
The hollow body structure contains nested functional elements within its interior cavity. The elastomer material is positioned inside the hollow cavity to provide vibration damping, while weight portions are strategically placed within the same cavity space. This nesting approach maximizes the use of internal volume for multiple functions: structural reinforcement through the hollow geometry, vibration control via elastomer, and weight optimization through positioned inserts, all without requiring additional external components.
