Golf Club Head Multi-Axis Center of Gravity Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf club head designs do not allow for optimal adjustment of center of gravity along multiple axes, limiting the flexibility and precision in weight distribution.
Innovation Solution
A golf club head design featuring adjustable weights and an elongated weight arm with multiple openings and a tube system that allows for vertical and horizontal adjustment of the center of gravity, using removable weight cartridges and screws for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If adjustable weights are added to the golf club head, then center of gravity adjustability is improved, but device complexity increases
Solution Approach 1:
The weighting system is divided into separate modular components: individual weight members that can be independently positioned in multiple locations, and a weight retention member that secures them. This segmentation allows flexible center of gravity adjustment without requiring a complex integrated mechanism, as each weight can be independently placed to achieve desired weight distribution.
Solution Approach 2:
The patent extends center of gravity adjustment from traditional single-axis (vertical) to multi-dimensional by allowing weight placement along the horizontal axis (heel-toe direction) in addition to vertical positioning. The weight retention member with multiple engagement locations enables adjustment along both vertical and horizontal dimensions, providing comprehensive center of gravity control.
2Measurement precision
If multiple adjustment mechanisms are provided for vertical and horizontal axes, then center of gravity control precision is improved, but ease of operation deteriorates
Solution Approach 1:
The patent combines vertical and horizontal adjustment capabilities into a single integrated weight retention member that can engage at multiple locations along both axes. Instead of requiring separate mechanisms for vertical and horizontal adjustment, the unified retention member allows the user to achieve multi-dimensional center of gravity positioning through a single engagement action, maintaining ease of operation while providing precise multi-axis control.
3Adaptability or versatility
If weights are made visible on the club head, then adjustability is improved, but appearance is worsened
Solution Approach 1:
The patent extracts the adjustment functionality from visible external components and integrates it into the club head's internal structure. The weight retention member is positioned within the club head body, and weights are secured internally, allowing full adjustment capability while maintaining a clean, uncluttered external appearance. The adjustment mechanism is effectively hidden within the club head's cavity.

AI summary
A golf club head with means for adjusting a center of gravity location along more than one axis is disclosed herein. The golf club head comprises one or more adjustable features, including a weight arm for receiving removable weights, e.g., slidable weights or weight screws, and one or more invertible weight cartridges that fit within a tube extending between the golf club head's crown and sole via an interior cavity. The weight arm fits within a rectangular, elongated recess in the sole and permits the golfer to adjust the location of one or more removable weights along its length.
