Composite Golf Club Head Weight Port Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional golf club heads with a center of gravity positioned rearward from the front face experience deleterious effects such as increased side-spin and reduced backspin for off-center hits, limiting face size and club length due to mass distribution and dynamic loft issues, and require new club heads for weight adjustments.
Innovation Solution
A golf club head with integrally formed composite sole weight ports and removable metal weights, allowing adjustable swing weight and moment of inertia by positioning weights at specific locations on the club head, enabling golfer-specific adjustments without manufacturing new heads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the center of gravity is positioned further rearward from the front face to increase moments of inertia, then forgiveness for off-center hits is improved, but side-spin increases and backspin decreases causing deleterious effects on ball flight
Solution Approach 1:
The patent applies local quality by positioning weights at specific locations within the club head (heel, toe, crown, or sole) rather than uniformly distributing mass. This allows precise control over center of gravity position and moment of inertia while minimizing deleterious side-spin and backspin effects on off-center hits.
Solution Approach 2:
The patent enables parameter changes by providing adjustable weights that can be removed and repositioned to different locations within the club head. This allows golfers to optimize the center of gravity position and moment of inertia parameters to achieve desired ball flight characteristics while avoiding excessive side-spin and backspin.
2Area of stationary object
If the face size is increased to maximize hitting area, then more hit locations are covered, but deleterious effects increase in a non-linear manner reducing practical benefits
Solution Approach 1:
The patent applies local quality by using adjustable weights to create non-uniform mass distribution within the club head. This allows optimization of moment of inertia and center of gravity position to compensate for the increased face area, ensuring that hits across the expanded face area do not produce excessive side-spin or backspin.
3Manufacturing precision
If new club heads are manufactured for weight adjustments, then precise center of gravity control is achieved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent applies segmentation by separating the club head into a main body and removable weight components. This allows the club head to be manufactured once with weight ports, and then weights can be adjusted independently without requiring new club head manufacturing, thereby reducing manufacturing complexity while maintaining precise center of gravity control.
Solution Approach 2:
The patent applies dynamics by making the weight configuration adjustable and changeable after manufacturing. The removable weights allow the center of gravity to be dynamically repositioned without remanufacturing the club head, providing manufacturing efficiency with precision control.
