Adjustable Golf Club Weight for Center of Gravity Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current golf club heads lack an adjustable weight system that allows users to customize the center of gravity and moment of inertia for varying performance characteristics across different courses or holes, affecting the flight direction and distance of the golf ball.
Innovation Solution
An adjustable weight system for golf club heads, where a repositionable weight member is placed adjacent to the sole portion, shifting the center of gravity towards or away from the strikeface, allowing users to change the vertical spin rate of the golf ball by adjusting the weight pad's position and angle, while maintaining aerodynamic properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a repositionable weight member is added to adjust center of gravity and moment of inertia, then adaptability and performance customization are improved, but device complexity increases
Solution Approach 1:
The weight member is designed to be repositionable within the club head, allowing dynamic adjustment of its position to change the center of gravity and moment of inertia. This enables the club to adapt to different playing conditions and user preferences, resolving the contradiction by making the system dynamically adjustable rather than fixed
Solution Approach 2:
The weight system is segmented into a separate, removable weight member that can be independently positioned within the club head. This segmentation allows the weight component to be adjusted without affecting the rest of the club structure, adding adaptability while keeping the overall device complexity manageable through modular design
2Manufacturing precision
If the weight member is placed adjacent to the sole portion to shift center of gravity, then manufacturing precision and performance control are improved, but ease of manufacture worsens
Solution Approach 1:
The weight member is designed as a separate component that can be independently manufactured and then installed in the club head. This segmentation allows for precise manufacturing of the weight member itself while simplifying the overall assembly process, as the weight component can be produced separately with high precision and then integrated into the club head structure
Solution Approach 2:
The weight member acts as an intermediary component that mediates between the club head structure and the performance requirements. By placing it adjacent to the sole portion, it precisely controls the center of gravity position while being a separate, easily manufacturable component that doesn't require complex integration into the club head

AI summary
A golf club head includes a body having a heel portion, a toe portion, a sole portion, and an outer surface, a strikeface having a geometric center, a head center of gravity, and a weight member including a weight pad. The weight member is configured to be repositionable by the user to a first position or a second position. The club head having the weight member in the first position shifts the head center of gravity toward the strikeface, and the club head having the weight member in the second position shifts the head center of gravity away from the strikeface.
