Golf Club Weight Member With Spring Feature
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf club heads face challenges in maximizing peripheral weight and moment of inertia due to the cylindrical shape of moveable weights and composite structures, which can lead to delamination or corrosion, affecting performance and durability.
Innovation Solution
A golf club head design featuring a hollow construction with a weight mount and movable weight member, utilizing spring features that flex and abut the perimeter wall for secure attachment without protruding into the center, allowing for adjustable weight placement and minimizing structural interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If cylindrical moveable weights are used in golf club heads, then the weights can be easily manufactured and installed, but the peripheral weight is reduced and moment of inertia is not maximized
Solution Approach 1:
The weight member is divided into multiple separate weight portions or segments that can be independently positioned within the club head. This segmentation allows the weights to be strategically placed at peripheral locations to maximize moment of inertia while maintaining ease of installation through modular components.
Solution Approach 2:
The weight member transitions from a simple cylindrical shape to a multi-dimensional structure with varying mass distribution. The weight includes non-cylindrical portions or asymmetric mass distribution that enables peripheral weight placement while maintaining manufacturability through advanced casting or machining processes.
2Adaptability or versatility
If composite structures with multiple materials are used in golf club heads, then mass can be selectively placed to optimize performance, but delamination or corrosion occurs over time
Solution Approach 1:
Multiple weight portions that were previously separate composite components are merged into a single integrated weight member. This monolithic structure eliminates the interfaces between different materials that cause delamination and corrosion, while still allowing selective mass placement through the overall geometry and density distribution of the unified component.
Solution Approach 2:
The weight member utilizes composite materials with different densities strategically distributed within a single component. By varying the material composition or density within different regions of the weight member, selective mass placement is achieved without requiring separate bonded components, thereby maintaining structural integrity.
3Ease of operation
If weights protrude into the center of the club head, then attachment is simplified, but the center of gravity location is negatively affected
Solution Approach 1:
The weight member is nested within a dedicated cavity or recess in the club head body, with the weight's outer surface conforming to the cavity walls. This nesting arrangement allows the weight to be securely attached without protruding into the center of the club head, preserving center of gravity optimization while maintaining simple attachment through the nested fit.

Function Achieved in This Case
The design enhances the club's ability to resist twisting during off-center impacts, maintains performance, and reduces the risk of delamination or corrosion, while allowing for adjustable center of gravity optimization.
Implementation Method 1
a spring feature. At least a portion of the spring feature is movably coupled to the weight body so that it is movable between a first configuration and a second configuration

AI summary
A golf club head includes a club head body and a weight member that is secured to the body in a weight mount. The weight member is constructed to utilize lateral forces to couple to the head body to minimize the structure required to retain the weight member. The weight member includes a spring feature that is movably coupled to a weight body so that it is movable between a first configuration and a second configuration. In the second configuration a portion of the spring feature extends outward from a side wall of the weight body. The weight mount includes an undercut and the spring feature extends into the undercut and is partially flexed by the abutment of the spring feature and a perimeter wall of weight mount when the weight member is disposed in the weight mount.
