Adjustable Golf Club Weighting System for Center of Gravity Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current golf club heads with weighting systems require complex and bulky internal structures, which negatively impact the club head's moment of inertia and center of gravity position, limiting user adjustability and affecting ball flight characteristics.
Innovation Solution
A golf club head with a multi-component adjustable weighting system that includes a member with attachment locations for weights, allowing for user-adjustable positioning of the club head's center of gravity without compromising moment of inertia or center of gravity position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a weighting system is added to adjust center of gravity and moment of inertia, then user adjustability of ball flight characteristics is improved, but the internal structure becomes bulky and complex, reducing moment of inertia and moving center of gravity upward and forward
Solution Approach 1:
The weighting system is divided into separate modular weights that can be independently positioned in different locations within the club head cavity. Each weight can be adjusted separately to achieve desired center of gravity and moment of inertia characteristics without requiring a complex integrated structure.
Solution Approach 2:
The patent utilizes the three-dimensional cavity space within the club head by positioning weights at various depths and lateral locations. This spatial distribution allows adjustment of ball flight characteristics while maintaining a compact overall structure that does not compromise moment of inertia.
2Reliability
If weights are positioned closer to the sole, face, and perimeter of the club head, then center of gravity position and moment of inertia are improved, but user adjustability of weighting is limited
Solution Approach 1:
The weighting system allows dynamic repositioning of weights to multiple predetermined locations within the cavity. Users can adjust weight positions between different configurations (e.g., heel/toe, front/back, high/low positions) to optimize for different playing conditions and shot types while maintaining proper moment of inertia and center of gravity characteristics.
Solution Approach 2:
The same weighting system structure serves multiple functions: it provides user adjustability for different ball flight preferences, maintains optimal moment of inertia through strategic weight placement in the cavity, and allows customization for various skill levels and playing styles without requiring different club head designs.

AI summary
A golf club head includes a club body having a crown opposite a sole, a toe end opposite a heel end, a back end, and a hosel. The golf club head also includes an adjustable weighting system positioned on the club body, the adjustable weighting system includes a single channel and a member that is received by the single channel and fastened to the club body, where a plurality of weights are coupled to the member. The golf club head can additionally or alternatively include a face angle adjustment system positioned on the sole, the face angle adjustment system includes a member that is removably received by the single channel and fastened to the sole, the member includes a first end member and a second end member, wherein the member is configured to be repositioned within the channel to adjust a resting face angle of the golf club head.
