High Density Golf Club Head Coating for Center of Gravity Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current golf club head designs face challenges in precisely optimizing the center of gravity position and increasing the moment of inertia, which affects the consistency and performance of golf shots, particularly for off-center hits, due to complex manufacturing processes and aerodynamic issues associated with weighting ports.
Innovation Solution
A high-density thin outer layer coating is applied to the golf club head, strategically positioned to maximize weight distribution at the perimeter, allowing for precise control of the center of gravity and increased moment of inertia through variable thickness and material density, using methods like vapor deposition or plasma spray.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If weighting ports or inserts are used to optimize center of gravity position and increase moment of inertia, then the center of gravity position can be adjusted, but the manufacturing process becomes complicated and aerodynamics are affected
Solution Approach 1:
The patent extracts the weighting function from separate ports or inserts and integrates it directly into the club head body through strategically placed high-density material regions. This eliminates the need for separate weighting components and their associated assembly processes, thereby reducing manufacturing complexity while maintaining precise center of gravity control.
Solution Approach 2:
The patent applies local quality by concentrating high-density material in specific strategic locations within the club head body rather than using uniform distribution. This localized placement allows precise control of center of gravity position and moment of inertia while using less total material and simplifying the manufacturing process compared to traditional weighting ports.
2Manufacturing precision
If weighting ports are used to adjust center of gravity, then center of gravity position can be optimized, but the overall aerodynamics of the club head are affected
Solution Approach 1:
The patent merges the weighting function with the club head body structure itself, eliminating separate weighting ports that would disrupt airflow. The high-density material is integrated into the body in a way that maintains the club head's aerodynamic contours, thus optimizing both center of gravity position and aerodynamic performance simultaneously.
3Strength
If traditional weighting methods are used, then moment of inertia can be increased, but the precision of weight distribution control is limited
Solution Approach 1:
The patent employs parameter changes by varying the density, volume, and spatial distribution of high-density material regions within the club head body. This allows precise control of weight distribution to achieve specific center of gravity positions and moment of inertia values, providing greater manufacturing precision compared to traditional weighting methods.
