Solution Overview

Problem

Conventional golf clubs have fixed lengths, which may not accommodate individual physical characteristics and play styles, leading to suboptimal performance.

Innovation Solution

The development of adjustable length golf clubs with a telescoping shaft system, where one shaft is insertable within the other, allowing for adjustable length through a locking mechanism, enabling customization of club length based on user needs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If fixed length golf clubs are used, then manufacturing simplicity is maintained, but adaptability to individual user needs deteriorates

Engineering Contradiction:

Improveadaptability to user needsVSAvoidclub structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The golf club shaft is divided into multiple telescoping segments that can slide relative to each other, allowing the club length to be adjusted in discrete increments. This segmentation enables adaptability while maintaining manageable structural complexity through modular design

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The shaft segments are designed with nested hollow structures where one segment fits inside another, creating a telescoping mechanism. This nesting approach provides length adjustment capability while minimizing the space required for the adjustment mechanism

Inventive Principle:

Principle #7Nested doll (Nesting)

2Adaptability or versatility

If telescoping shaft system is implemented, then length adjustability is improved, but structural complexity increases

Engineering Contradiction:

Improvelength adjustabilityVSAvoidshaft system complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The shaft system transitions from a static fixed-length structure to a dynamic telescoping structure that can change length during use. This dynamic capability is achieved through sliding segments with locking mechanisms that maintain stability when adjusted

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

Locking mechanisms serve as intermediary components between the telescoping shaft segments, providing a simple method to secure the segments at desired positions. These intermediaries enable length adjustment without requiring complex fastening systems

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If adjustable length mechanism is added, then user comfort is improved, but manufacturing complexity increases

Engineering Contradiction:

Improveuser comfortVSAvoidmanufacturing complexity

Core Design Contradiction:

Ease of operationVSEase of manufacture

Solution Approach 1:

The shaft is manufactured as separate segments that can be produced using standard manufacturing processes, then assembled through telescoping and locking mechanisms. This segmentation allows each component to be manufactured independently with conventional methods

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The shaft segments are pre-manufactured with precision-bored hollow structures and integrated locking features during initial production. This preliminary preparation simplifies final assembly and reduces the need for complex post-manufacturing operations

Inventive Principle:

Principle #10Preliminary action
