Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Golf clubs with fixed coupling mechanisms require a large number of variations to accommodate individual characteristics and preferences, and existing adjustable mechanisms can introduce instability and stress concentrations, limiting flexibility and cohesion.

Innovation Solution

A golf coupling mechanism featuring a shaft sleeve with arcuate surfaces that restrict rotation relative to the golf club head, combined with a shaft receiver with complementary arcuate surfaces, allowing for adjustable lie and loft angles through various configurations, while minimizing mass and aerodynamic drag.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If adjustable coupling mechanisms are used to change club features, then flexibility and adaptability improve, but stability and cohesion deteriorate due to stress concentrations

Engineering Contradiction:

Improveadjustability of club featuresVSAvoidstability of coupling

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The coupling mechanism allows dynamic adjustment of lie and loft angles through movable components including a rotatable shaft sleeve and adjustable couplers, enabling the club to adapt to different player characteristics while maintaining structural integrity through controlled movement rather than fixed rigid connections

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The coupling mechanism is divided into separate adjustable components including a shaft sleeve, first coupler, second coupler, and locking mechanism that can be independently positioned and locked, allowing precise adjustment of club geometry without creating stress concentrations at fixed joints

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If multiple golf clubs with fixed coupling mechanisms are maintained to accommodate individual characteristics, then adaptability improves, but device complexity and quantity of equipment increases

Engineering Contradiction:

Improvecustomization to individual characteristicsVSAvoidnumber of golf clubs required

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A single golf club with the adjustable coupling mechanism can perform the function of multiple different clubs by allowing adjustment of lie angle, loft angle, and shaft configuration, eliminating the need to maintain and switch between multiple fixed clubs to accommodate different player characteristics

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If adjustable coupling mechanisms are implemented, then flexibility improves, but mass and aerodynamic drag increase

Engineering Contradiction:

Improveadjustability of club configurationVSAvoidmass of coupling mechanism

Core Design Contradiction:

Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The adjustable components are strategically positioned at specific locations on the club shaft and head where adjustment is most needed, rather than distributing adjustment mechanisms throughout the entire club structure, thereby minimizing added mass while preserving necessary adjustability for lie and loft angles

Inventive Principle:

Principle #3Local quality
