Weighted Putter Head with Perimeter Mass and Polymeric Insert
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional putters often prioritize aesthetics and personalization over performance, leading to instability, inaccuracy, and reduced enjoyment due to limited weight distribution and sweet spot size, necessitating adjustments in stroke or club characteristics.
Innovation Solution
A weighted putter design with a hollow polygonal head distributing weight to the perimeter, a polymeric face insert, and a heavy grip, combined with an S-shaped shaft and adjustable weight system, to enhance stability and sweet spot size, while maintaining center face balance and allowing for variable loft and ground clearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If weight is distributed to the perimeter of the putter head, then stability and moment of inertia are improved, but manufacturing complexity increases
Solution Approach 1:
The putter head is divided into a perimeter weighting system with separate weight inserts positioned at the toe, heel, and crown areas. This segmentation allows independent placement of weights to maximize moment of inertia while maintaining manufacturing feasibility through modular assembly.
Solution Approach 2:
Weight inserts are nested within hollow cavities or channels formed in the putter head perimeter. This nesting approach concentrates mass at the edges without requiring additional external components, reducing manufacturing complexity while achieving the desired weight distribution.
2Stability of the object's composition
If a heavy grip is used, then club balance and stability are improved, but overall club weight increases
Solution Approach 1:
The grip is designed with non-uniform density, featuring higher density materials or added weighting specifically in the lower portion of the grip near the hands. This local quality enhancement improves club balance and stability without uniformly increasing the weight of the entire grip, minimizing the impact on overall club weight.
3Measurement precision
If the sweet spot is enlarged, then accuracy is improved, but moment of inertia distribution becomes more complex
Solution Approach 1:
The putter head features an asymmetric weight distribution with concentrated masses at specific perimeter locations (toe, heel, crown) rather than uniform distribution. This asymmetric arrangement enlarges the effective sweet spot by creating multiple high-moment-of-inertia zones, improving accuracy while managing complexity through strategic rather than uniform weight placement.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design provides increased stability, accuracy, and repeatable strokes by maximizing moment of inertia, enlarging the sweet spot, and reducing muscle exertion, resulting in improved club performance and balance.
Implementation Method 1
The hollowed head allows the weight of the putter to be distributed to the perimeter which stabilizes the motion as it moves through the stroke or moment of inertia
Implementation Method 2
The face of the putter incorporates a polymeric member which gives the ball more impact feel with the face
Implementation Method 3
a grip including a resilient material that extends approximately half the length of the shaft

AI summary
An improved putter and method of use utilizing a putter shaft having a rectangular grip extending approximately half the shaft length. A polygonal-like ring provides a flat face with an extended toe and a short heel. The face of the putter head has a polymeric insert for weight redistribution and for better putting feel. The sides of the putter include triangular shaped indents also for weight redistribution. The rear of the putter head is arched to prevent ground contact during putting and further to increase head stability during the stroke.
