Two-Component Golf Club Head Mass Redistribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current golf club head designs face challenges in maximizing discretionary mass to enhance moment of inertia and lower the center of gravity, which are crucial for improving golf ball flight characteristics such as launch angle, distance, and reducing spin.
Innovation Solution
A two-component design featuring a metallic first component and a non-metallic second component, where the metallic component forms the load-bearing structure and majority of the club head mass, and the non-metallic component wraps around to form the crown, heel, and sole, allowing for adjustable weights and mass pads to redistribute mass for optimal performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If all-metal club head design is used, then structural strength is maintained, but discretionary mass is limited and cannot be optimized for performance
Solution Approach 1:
The club head is divided into multiple components: a first component (typically metal) providing structural strength, a second component (typically composite material) forming the crown and sole, and a third component (weight) for mass optimization. This segmentation allows each component to be optimized for its specific function while achieving overall performance goals that would be impossible with a single-material design.
Solution Approach 2:
The patent combines different materials with complementary properties: metal provides strength and durability, composite materials (such as carbon fiber reinforced polymers) provide lightweight structural support and design flexibility, and dense weights (such as tungsten) provide adjustable mass. This composite approach enables optimization of discretionary mass distribution without compromising structural integrity.
2Adaptability or versatility
If constant total swing weight is maintained, then structural mass must be minimized, but control over specific mass distribution is reduced
Solution Approach 1:
The weight component is designed to be adjustable and reconfigurable, allowing golfers to change mass distribution based on performance needs. The weight can be positioned at different locations (heel, toe, front, back) or completely removed, providing dynamic adaptability. This enables customization of moment of inertia and center of gravity position while maintaining constant total swing weight.
Solution Approach 2:
The patent allows modification of key parameters such as moment of inertia and center of gravity position by changing weight location and configuration. Users can adjust these parameters to optimize for different shot types, conditions, or personal preferences, while the total mass remains constant to maintain consistent swing weight.
3Stability of the object's composition
If discretionary mass is increased to maximize moment of inertia, then club head stability improves, but center of gravity position becomes harder to optimize
Solution Approach 1:
The weight component is strategically positioned in specific locations (heel, toe, front, or back of the club head) to locally add mass where needed. This localized mass addition allows independent optimization of moment of inertia (for stability) and center of gravity position (for launch characteristics) without requiring uniform mass distribution throughout the club head.

AI summary
Embodiments of wood-type club heads comprising one or more components are described herein. The wood-type club head comprises a first, metallic component, and a second, non-metallic component. The first component comprises the load bearing structure that forms the striking face, and portions of the crown, the heel, the toe, and the sole. The second component comprises a lightweight structure that wraps around the first component to form portions of the crown, the heel, the toe, and the sole. The first component comprises the majority of the club head mass and can receive removable weights. The two-component design allows for additional discretionary mass redistribution to improve center of gravity location and moment of inertia.
