Solution Overview

Problem

Existing golf putters lack effective weight distribution, alignment aids, and visual contrast for improved sound, feel, and forgiveness, which are crucial for enhancing a golfer's putting performance.

Innovation Solution

A golf putter constructed from three separate body members made of different materials and densities, each with distinct visual and alignment features, including sightlines and weight ports, to enhance weight distribution, alignment, and visual contrast.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a putter is constructed from three separate body members with different materials and densities, then weight distribution and forgiveness are improved, but device complexity increases

Engineering Contradiction:
Improveweight distributionVSAvoidconstruction complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The putter head is divided into three separate body members (first body member with striking face, second body member, and third body member) that can be manufactured independently from different materials and then assembled together. This segmentation allows optimization of each component for specific functions while achieving superior overall weight distribution and forgiveness compared to a monolithic construction.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent employs composite construction by combining three different body members made from materials with different densities and properties. This composite approach enables precise control over the putter's center of gravity, moment of inertia, and overall weight distribution, thereby improving forgiveness and sound characteristics while managing the added construction complexity through standardized assembly interfaces.

Inventive Principle:
Principle #40Composite materials

2Reliability

If body members are made from different materials with different densities, then sound and feel are improved, but manufacturing complexity increases

Engineering Contradiction:
Improvesound and feelVSAvoidmanufacturing complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

By segmenting the putter into three separate body members that can be manufactured independently, the patent enables the use of different materials for each component without compromising manufacturability. Each body member can be optimized for its specific function (striking face, weight distribution, structural support) using the most suitable material, while standardized connection interfaces simplify the assembly process.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent utilizes material density as a key parameter to optimize sound and feel characteristics. By selecting materials with different densities for the three body members, the putter achieves superior acoustic properties and tactile feedback. The manufacturing process accommodates these material variations through controlled assembly procedures that ensure proper alignment and connection despite the different material properties.

Inventive Principle:
Principle #35Parameter changes

3Measurement precision

If multiple body members are assembled together, then alignment and visual contrast are improved, but assembly complexity increases

Engineering Contradiction:
ImprovealignmentVSAvoidassembly complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The putter is segmented into three body members with dedicated alignment features (such as alignment pins, recesses, or reference surfaces) that facilitate precise assembly. These segmentation-specific alignment mechanisms ensure accurate positioning of each component relative to the others, thereby improving overall alignment and visual contrast without creating excessive assembly complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent employs visual contrast through different material finishes, colors, or surface treatments on the three body members to enhance alignment cues during assembly and use. These visual differentiation strategies make it easier to identify proper alignment and component orientation, reducing assembly complexity by providing intuitive alignment references that guide the assembly process.

Inventive Principle:
Principle #32Color changes
