Golf Club Head Weight Distribution via Segmented Mass
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current golf club heads lack optimal distribution of weight and moment of inertia, leading to suboptimal trajectory and spin rates of golf balls, as existing materials and designs do not effectively balance center of gravity and moment of inertia for improved performance.
Innovation Solution
The golf club head design incorporates multiple sets of weight portions made from different materials, such as steel-based and tungsten-based materials, strategically positioned to optimize the center of gravity and moment of inertia by using various manufacturing methods like bonding, welding, and mechanical locking, allowing for adjustable weight distribution and improved structural integrity.
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 discrete weight portions made from different materials (steel, tungsten, tungsten carbide) that can be independently positioned and adjusted. This segmentation allows precise control over center of gravity location and moment of inertia distribution while maintaining manufacturing feasibility through modular assembly.
Solution Approach 2:
The patent employs composite construction by integrating multiple materials (steel-based materials, tungsten-based materials, tungsten carbide) within the golf club head structure. Each material contributes different density and weight characteristics, enabling fine-tuned optimization of center of gravity and moment of inertia to improve ball trajectory and spin rate.
2Manufacturing precision
If multiple weight portions are strategically positioned, then the moment of inertia is optimized, but the manufacturing process becomes more complex
Solution Approach 1:
The weight distribution system is segmented into multiple independent weight portions that can be manufactured separately and then assembled into the golf club head. This allows each weight portion to be precisely formed with specific densities and positions, optimizing moment of inertia while simplifying the overall manufacturing through modular assembly rather than complex integrated casting.
Solution Approach 2:
The patent utilizes parameter changes by varying the material composition (steel, tungsten, tungsten carbide) and spatial positioning of weight portions to achieve desired moment of inertia characteristics. By adjusting material density parameters and positional parameters, optimal performance is achieved without requiring complex manufacturing processes for each configuration.
