Golf Club Head Weight Distribution via Segmented Materials
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 fail to effectively balance center of gravity and moment of inertia.
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, which are integrated into the body portion to enhance weight distribution and 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 functional zones with different weight portions (first weight portion, second weight portion, third weight portion) made from different materials, each positioned to optimize specific aspects of center of gravity and moment of inertia independently
Solution Approach 2:
The club head incorporates composite construction using multiple materials including steel-based materials, tungsten-based materials, and titanium-based materials in different weight portions to achieve precise weight distribution and optimize both center of gravity position and moment of inertia values
2Manufacturing precision
If weight portions are strategically positioned to optimize moment of inertia, then trajectory and spin rate improve, 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 club head, allowing each portion to be optimized for specific moment of inertia requirements without complicating the entire manufacturing process
Solution Approach 2:
Weight portions are pre-manufactured with precise weights and dimensions before being integrated into the club head assembly, allowing for accurate moment of inertia optimization to be achieved through standardized components rather than complex custom manufacturing

AI summary
Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a golf club head may include a face portion having a front surface and a back surface with a plurality of back surface grooves. Each back surface groove includes a groove opening with a groove opening width and an interior groove width at a location inside the back surface groove. The interior groove width is greater than the groove opening width. The golf club head further includes a body portion and an interior cavity enclosed by coupling the face portion and the body portion, a port connected to the interior cavity; and a polymer material injected into the interior cavity from the port and filling the plurality of back surface grooves. Other examples and embodiments may be described and claimed.
