Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing golf putter heads and putters fail to provide consistent and high-quality ball roll with minimal skidding, and there is a need for designs that accommodate individual golfer's unique stroke arcs.

Innovation Solution

Design of uniquely balanced putter heads with symmetrical weight distribution and adjustable toe hang, featuring a one-piece body with precise loft angles and adjustable weights to optimize ball striking performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If high loft (5 degrees or more) is used in putter heads, then the putter head generates more upward force on the ball, but this produces more bouncing and skidding of the ball before it begins to roll

Engineering Contradiction:

Improveupward force on ballVSAvoidball roll quality

Core Design Contradiction:

ForceVSReliability

Solution Approach 1:

The patent changes the loft angle parameter from conventional high values (5 degrees or more) to a low value of approximately 0.5 degrees. This parameter change reduces the upward force on the ball, allowing it to roll more smoothly with less bouncing and skidding, thereby improving ball roll quality while maintaining effective putting performance

Inventive Principle:

Principle #35Parameter changes

2Ease of manufacture

If unbalanced putter head design is used, then manufacturing is simpler, but this produces poor heal to toe balance and affects ball roll quality

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidheal to toe balance

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The patent employs asymmetric weight distribution within the putter head body, positioning heavier material toward the heel side and lighter material toward the toe side. This deliberate asymmetry creates the desired heal-to-toe balance (approximately 30-40% heel weight distribution) that improves ball roll quality while remaining manufacturable through conventional casting or machining processes

Inventive Principle:

Principle #4Asymmetry

3Device complexity

If fixed toe hang design is used, then device structure is simpler, but this cannot accommodate individual golfer's unique stroke arcs

Engineering Contradiction:

Improvestructure complexityVSAvoidaccommodation of stroke arc

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent implements an adjustable toe hang mechanism that allows the putter head to rotate around the shaft axis to different angular positions. This dynamic adjustment capability enables golfers to customize the toe hang angle (e.g., face balanced, quarter toe hang, half toe hang, or full toe hang) to match their individual stroke arc characteristics, thereby improving adaptability without significantly complicating the overall device structure

AI summary

Golf putter heads, golf fitting putter heads, golf putters, and golf fitting putters. The putter heads include a body that is one-piece, formed, and generally rectangular, having a base portion having a trailing edge, and a ball strike portion. The ball strike portion has a heal, a toe, a ball striking face, a length measured along the ball striking face from the heal to the toe, and a midpoint along the length. The body is divided into symmetrical halves measured from the midpoint to achieve balance of weight measured along the length of the ball strike portion, with the ball striking face having a loft angle varying from about 0 to about 1 degree +/−0.1 degree. The fitting heads include a slot in which weights and/or the hosel may be moved to adjust toe hang.
