Solution Overview

Problem

Current techniques for dynamically adjusting the weight of golf club irons or wedges are limited and often permanent or time-consuming, such as material removal or addition, which do not allow for quick customization.

Innovation Solution

A removable weight system for golf club heads that can be easily installed and adjusted to modify mass, center of gravity, and moment of inertia, using a body and cover portion made of various metals, allowing for dynamic fine tuning post-manufacturing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If material removal or addition techniques are used to adjust weight, then weight adjustment is possible, but the process is permanent and time-consuming

Engineering Contradiction:
Improveweight adjustment flexibilityVSAvoidadjustment time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The weight adjustment system is segmented into a removable weight component and a corresponding recess in the club head. This allows the weight to be independently removed and repositioned without permanent alterations to the club head structure, enabling quick adjustments while maintaining adaptability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The weight is designed to be dynamic rather than fixed - it can be removed from one position and placed in another position within the recess. This dynamic capability allows the club head characteristics to be adjusted quickly without the time-consuming process of permanent material removal or addition.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If removable weight system is implemented, then customization flexibility is improved, but device complexity increases

Engineering Contradiction:
Improvecustomization flexibilityVSAvoidweight system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The weight adjustment functionality is extracted as a separate removable component rather than being integrated into the club head structure. This allows the weight to be independently handled, removed, and repositioned, providing customization flexibility while keeping the overall system relatively simple by avoiding complex integration requirements.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The removable weight and its corresponding recess serve multiple functions: they provide weight adjustment, allow customization of club head characteristics, and can be easily installed or removed without specialized tools. This multi-functionality achieves customization flexibility without requiring overly complex device architecture.

Inventive Principle:
Principle #6Universality (Multi-functionality)
