Solution Overview

Problem

Golfers face the expense of purchasing multiple drivers with different shapes to achieve varying performance characteristics, as each shape offers distinct advantages in terms of shot dispersion, distance, and weight distribution, but existing solutions do not provide a cost-effective way to switch between these configurations.

Innovation Solution

A modular golf driver head kit comprising a front portion and interchangeable rear portions of different shapes, secured by releasable fasteners, allowing users to change between square, triangular, and pulled-back configurations to optimize performance based on playing conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple drivers with different shapes are purchased to achieve varying performance characteristics, then performance versatility is improved, but cost increases

Engineering Contradiction:

Improveperformance versatilityVSAvoidcost

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The driver head is divided into a front portion and a rear portion that can be separated and recombined. The front portion contains the face and hosel, while the rear portion contains the weight and shape-defining elements. This segmentation allows the rear portion to be exchanged between different driver heads, providing multiple shape configurations without purchasing multiple complete drivers, thereby reducing cost while maintaining performance versatility.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The front portion is designed with a universal interface (threaded hole pattern) that can accommodate multiple different rear portions. This allows a single front portion to serve multiple functions by pairing with different rear portions, enabling one driver head to provide the performance characteristics of multiple different driver shapes without requiring multiple separate purchases.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If adjustable weight is used to influence shot trajectory, then adaptability is improved, but moment of inertia decreases

Engineering Contradiction:

Improveshot trajectory adjustmentVSAvoidmoment of inertia

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The weight system is segmented into separate adjustable weights that can be positioned within the rear portion. This allows independent adjustment of weight position to influence shot trajectory while maintaining the overall structural integrity and MOI of the driver head, as the weights are distributed within the rear portion rather than concentrated at a single point that would compromise MOI.

Inventive Principle:

Principle #1Segmentation

AI summary

A golf driver kit includes a front portion and a plurality of rear portions exchangeably connectable to the front portion and being of different respective shapes for imparting different flight characteristics to a struck golf ball. The front portion includes a front face plate and a hosel for receiving a shaft, plus a rearwardly projecting base on which the rear portion is seated. The rear portion is removably attached to the front portion by screws.
