Adjustable Center of Gravity Golf Club Head
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current golf club designs, particularly drivers, face limitations in adjusting the center of gravity height due to USGA regulations, which restrict performance improvements such as increased head speed and better impact events with the golf ball, as larger geometries and inertia values can lead to reduced head speed and less effective off-center hits.
Innovation Solution
A golf club head with adjustable center of gravity assemblies, including tubes and weight cartridges that can be flipped to alter the center of gravity height, combined with a slidable weight assembly and a flat panel for sound attenuation and stability, allowing for customizable center of gravity positions and improved moment of inertia.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the driver head geometry is increased to improve inertia values and off-center hit performance, then forgiveness is improved, but head speed is reduced
Solution Approach 1:
The patent changes the parameter of center of gravity height through adjustable weight cartridges that can be positioned at different vertical locations within the driver head. This allows optimization of the moment of inertia to achieve better forgiveness while maintaining head speed, resolving the contradiction between increased geometry for forgiveness and head speed maintenance.
2Speed
If the center of gravity height is adjusted to improve club head speed, then ball velocity is improved, but design complexity increases
Solution Approach 1:
The patent segments the weight adjustment system into modular weight cartridges that can be independently positioned within the driver head. Each cartridge contains weights that can be flipped or repositioned to adjust the center of gravity height, creating a simplified adjustable mechanism that reduces overall device complexity while maintaining the ability to optimize club head speed.
3Reliability
If larger face geometry is used to improve off-center hit performance, then ball speed on off-center hits is improved, but head speed is reduced
Solution Approach 1:
The patent changes the parameter of center of gravity height through adjustable weight cartridges positioned within the driver head. This allows optimization of the moment of inertia to achieve better off-center hit performance without requiring larger face geometry, thereby maintaining head speed while improving forgiveness on off-center hits.
