Golf Putter Head with Concentrated Heel and Toe Weights
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current golf putter heads have a small sweet spot, making it difficult for golfers to consistently strike the ball effectively, leading to inconsistent and unpredictable putts, as the design does not adequately address the size and position of the sweet spot.
Innovation Solution
The putter head design concentrates weight at the heel and toe ends, providing exceptional rotational stability and a significantly larger sweet spot, allowing for precise strike control and energy transfer, with adjustable weights to customize balance and feel while maintaining the sweet spot's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If weight is added to the bottom of the putter head to improve balance and swing feel, then the overall weight and balance are improved, but the sweet spot is repositioned and its size is reduced
Solution Approach 1:
The putter head is divided into distinct functional zones: a heavy sole portion for balance and swing feel, and a separate face portion with engineered cavities for weight placement that maintains sweet spot positioning. This segmentation allows independent optimization of swing characteristics and ball strike properties.
Solution Approach 2:
Different portions of the putter head have different weight densities and properties. The sole is heavy for balance, while the face contains strategically placed cavities with specific weight materials to maintain the sweet spot at the center, creating local quality variations that serve different functions.
2Area of stationary object
If the sweet spot is made larger to improve putting consistency, then the size of the effective hitting area is improved, but the rotational stability of the putter face deteriorates
Solution Approach 1:
Heavy weights are placed in the sole portion of the putter head to act as counterweights that resist rotational movement of the putter face during the putting stroke. This counterbalancing effect stabilizes the face orientation while allowing a larger effective sweet spot area.
Solution Approach 2:
The moment of inertia of the putter head is modified by changing the weight distribution parameters - specifically placing heavy materials in the sole and using lightweight materials in the face cavities. This parameter change increases rotational stability while maintaining a larger sweet spot area.

AI summary
Briefly, a putter head is provided that concentrates the weight of the putter head at the far ends of the heel and toe of the putter head. The putter head has an ultralight putter body that includes a putter face and a shank for attaching a putter shaft. The ultralight putter body has an axially aligned heel cavity and toe cavity that are constructed to receive weights. The heel weight and toe weights are very dense, and constructed to be received into the respective weight cavity of the light putter body. Due to the extreme concentration of weight at the fare ends of the heel and toe of the putter head, the putter face has exceptional rotational stability with a substantially larger sweet spot than known putter heads. The weights may be provided as changeable weight pairs, such that the overall weight and balance of the putter head may be adjusted, while maintaining the position of the sweet spot.
