Solution Overview

Problem

Existing golf putters lack effective weight distribution, alignment aids, and visual contrast for improved sound, feel, and forgiveness during use.

Innovation Solution

A golf putter constructed from three separate body members made of materials with varying densities and colors, featuring sightlines and weight ports for enhanced weight distribution, alignment, and visual cues.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

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

Engineering Contradiction:
ImproveforgivenessVSAvoidconstruction 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 and then assembled together. This segmentation allows each component to be optimized for specific functions while enabling complex weight distribution patterns that would be difficult to achieve in a monolithic construction.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The three body members are made from materials with varying densities to create a composite structure. This allows precise control over the putter's center of gravity and moment of inertia, improving forgiveness and sound characteristics while maintaining the ability to customize weight distribution for specific performance goals.

Inventive Principle:
Principle #40Composite materials

2Object-generated harmful factors

If multiple body members with different densities are used, then sound and feel are improved, but manufacturing complexity increases

Engineering Contradiction:
Improvesound qualityVSAvoidmanufacturing complexity
Core Design Contradiction:
Object-generated harmful factorsVSEase of manufacture

Solution Approach 1:

By segmenting the putter into three separate body members, each can be manufactured using standard processes and then assembled together. This approach simplifies individual component manufacturing while enabling complex overall construction that would be difficult to achieve in a single piece.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The densities of the three body members are specifically selected to be different from one another, creating varying acoustic properties when the putter strikes the ground. This parameter change in material density allows optimization of sound and feel characteristics while maintaining manufacturability through standard material selection.

Inventive Principle:
Principle #35Parameter changes

3Measurement precision

If sightlines are formed on multiple body members, then alignment accuracy is improved, but device complexity increases

Engineering Contradiction:
Improvealignment accuracyVSAvoidfeature complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

Sightlines are formed on multiple body members with contrasting colors or visual characteristics. This creates visual contrast that enhances the golfer's ability to align the putter correctly, improving alignment accuracy without requiring complex mechanical alignment mechanisms.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The sightlines are distributed across multiple separate body members rather than being integrated into a single component. This segmentation of visual alignment cues allows each component to be optimized independently while collectively providing comprehensive alignment guidance.

Inventive Principle:
Principle #1Segmentation
