Golf Club Head Insert Layout for Face Compliance and CG Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf club irons fail to maximize performance improvements by optimizing the placement and compliance of slots and weight inserts, which are crucial for adjusting center of gravity and moment of inertia, and enhancing ball flight characteristics.
Innovation Solution
A golf club iron with a strategically positioned slot adjacent to the striking face, housing a weight insert, which is configured to move the center of gravity forward and downward, improving compliance and performance by adding mass to promote deflection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If weight inserts are added to adjust center of gravity and moment of inertia, then flight characteristics are improved, but device complexity increases
Solution Approach 1:
The weight insert is nested within a cavity formed in the sole of the club head, allowing the weight to be integrated into the existing structure without adding external components. This resolves the contradiction by incorporating the weight adjustment mechanism within the club head's internal geometry, maintaining flight characteristic improvement while minimizing device complexity
2Strength
If a slot is added to improve compliance, then compliance is improved, but manufacturing precision requirements increase
Solution Approach 1:
The slot is positioned specifically in the sole of the club head at a location that maximizes compliance improvement while maintaining structural integrity. By concentrating the compliance enhancement in a specific local area rather than throughout the entire club head, the design achieves improved compliance with manageable manufacturing precision requirements
3Strength
If the slot is positioned closer to the striking face, then compliance improvement is maximized, but manufacturing difficulty increases
Solution Approach 1:
The cavity and slot are designed to be formed during the casting or manufacturing process itself, rather than requiring post-manufacturing operations. The slot is positioned to extend from the sole toward the striking face, allowing compliance improvement to be achieved through the manufacturing process geometry rather than requiring difficult precision machining or assembly operations afterward
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The configuration enhances ball speed, increases distance with backspin, and provides better peak height, while improving the coefficient of restitution and loft characteristics.
Implementation Method 1
An insert can be placed inside the slot to add weight to the face portion of the golf club head in an attempt to move the center of gravity forward and/or downward relative to the same golf club head without the insert
Implementation Method 2
another way to further improve the performance of a golf club head is by increasing the compliance of the golf club head upon impact with a golf ball
