Adjustable Putter Head Weighting for Off-Center Twist Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Golf club heads, particularly putters, twist off-center causing inaccurate ball direction and skidding, which affects precision and consistency in golf shots.
Innovation Solution
Incorporation of repositionable weight assemblies, such as heel and toe weight assemblies, allowing for adjustable mass distribution to stabilize the club head and improve accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the club head is designed with fixed weight distribution, then the structure is simple, but the accuracy and consistency of ball motion deteriorates when hit off-center
Solution Approach 1:
The patent applies the dynamics principle by making the weight assemblies repositionable rather than fixed. The weight assemblies can be moved to different locations on the club head using threaded holes and set screws, allowing the center of gravity to be adjusted. This dynamic adjustment capability enables the club head to maintain accuracy and consistency across different shot conditions while keeping the overall structure relatively simple.
Solution Approach 2:
The patent implements parameter changes by allowing modification of the weight distribution parameters through repositioning the weight assemblies. By changing the location of weights along the longitudinal axis and across the face width, the center of gravity position can be optimized to reduce twisting and improve ball motion accuracy without requiring a completely complex structural design.
2Manufacturing precision
If the club head uses repositionable weight assemblies, then the accuracy and consistency of ball motion improves, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the weight system into separate, movable weight assemblies rather than using a single fixed weight structure. Each weight assembly can be independently positioned and secured, allowing for flexible adjustment of the center of gravity. This segmented approach improves accuracy while keeping each individual component relatively simple in design.
3Manufacturing precision
If the center of gravity is positioned to reduce twisting, then the ball direction accuracy improves, but the adjustability for different playing conditions is reduced
Solution Approach 1:
The patent resolves this contradiction by making the center of gravity position dynamic rather than static. The repositionable weight assemblies allow the center of gravity to be adjusted to different locations depending on the playing conditions, shot type, or player preference. This maintains ball direction accuracy for each specific configuration while providing versatility across multiple playing scenarios.
