Solution Overview

Problem

Golfers struggle to maintain proper arm positioning during a golf swing, which is crucial for mastering the game, as existing training methods are not effective in ensuring consistent arm alignment throughout the swing.

Innovation Solution

A spherical apparatus, either inflatable or non-inflatable, is held between the forearms with a lanyard around the neck to maintain proper arm alignment, providing immediate feedback if the arms separate improperly by falling out of position.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional training methods are used, then golfers can practice swings, but they cannot maintain proper arm positioning throughout the swing

Engineering Contradiction:

Improvearm positioning consistencyVSAvoidtraining complexity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The spherical apparatus provides immediate tactile feedback to the golfer's arms during the swing. When arms maintain proper position, the ball remains centered and stable. When arms separate or deviate from correct positioning, the ball shifts or falls, providing real-time feedback without requiring complex electronic sensors or instructors.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The spherical apparatus acts as an intermediary object between the golfer's forearms, creating a physical connection that enforces proper arm positioning. This mediator object translates the abstract concept of 'proper arm position' into a tangible, enforceable physical constraint that the golfer can feel and respond to during the swing.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Manufacturing precision

If a complex training apparatus is used to enforce arm position, then positioning accuracy improves, but device complexity increases

Engineering Contradiction:

Improvearm alignment precisionVSAvoidapparatus structure

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The training system is segmented into simple, independent components: a spherical apparatus and a lanyard. The sphere itself is a simple geometric form requiring no internal mechanisms, while the lanyard provides a separate, simple attachment system. This segmentation allows high precision in arm positioning enforcement without requiring a complex integrated structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of using complex sensors and actuators to actively control arm position, the invention inverts the approach by using a passive spherical object that naturally indicates position through its stability and placement. The system doesn't force arms into position through complex mechanisms, but rather allows the simple sphere to reveal whether correct position is achieved.

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

An apparatus configured to be held between a user's forearms during a golf swing. The apparatus can be a spherical, inflated ball. The apparatus may be further secured using a lanyard or similar article worn around the golfer's neck. In practice, by maintaining the inflated ball positioned between the forearms during the golf swing, the golfer is maintaining his or her arms in the proper position. If the inflated ball falls or fails to remain held in place between the forearms, the golf swing is poor (i.e., the arms have separated too much). Other spherical members can be used as well.
