Solution Overview

Problem

Golfers face challenges in consistently executing a proper golf swing, particularly in coordinating lower body movements with upper body actions, which are often overlooked in traditional training methods.

Innovation Solution

A feedback sensing system that includes foot and leg sensing devices, providing real-time feedback through visual, audible, and tactile indicators to guide golfers in achieving proper lower body positions and movements during a golf swing, specifically tracking the Lead Foot heel raise, Trail Leg knee bend, and heel lowering to facilitate a coordinated backswing and downswing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If traditional training methods focus on upper body elements, then upper body swing technique is improved, but lower body coordination and swing consistency deteriorate

Engineering Contradiction:

Improveupper body swing techniqueVSAvoidswing consistency

Core Design Contradiction:

Manufacturing precisionVSReliability

Solution Approach 1:

The system employs sensors (pressure sensors, accelerometers, gyroscopes) to detect lower body movements and provides real-time feedback through visual, audible, and tactile indicators. This feedback loop enables golfers to adjust their lower body positioning and movement sequences, improving coordination between upper and lower body while enhancing swing consistency through continuous monitoring and correction

Inventive Principle:

Principle #23Feedback

2Reliability

If real-time feedback sensing system is implemented, then swing coordination and consistency are improved, but device complexity increases

Engineering Contradiction:

Improveswing consistencyVSAvoidsensing system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The sensing system is divided into multiple independent sensor modules (pressure sensors in the mat, accelerometers and gyroscopes in wearable devices) that can be positioned at different locations. Each sensor type measures specific parameters independently, and their data is integrated by a processor to provide comprehensive feedback, reducing overall system complexity through modular design

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A feedback device serves as an intermediary between the sensors and the golfer, translating complex sensor data into simple visual, audible, and tactile indicators. This intermediary layer processes the raw sensor information and presents it in an easily interpretable format, reducing the perceived complexity for the user while maintaining comprehensive measurement capabilities

AI summary

Disclosed are various embodiments of golf training device that helps a golfer learn and coordinate lower body positions and movements with upper body movements, using a series of feedback signals. In one embodiment, among others, a system comprises a foot sensor that attaches to a Lead Foot of a user. The foot sensor is configured to detect a heel of the Lead Foot being raised. The system also comprises a leg sensor that attaches to a Trail Leg of the user, and the leg sensor detects a bend in the Trail Leg of the user. The foot sensor is configured to detect the heel being lowered at an instance after the detection of the bend in the Trail Leg. The system further comprises a feedback device configured to activate one or more feedback indicators after the detections of foot and/or leg movements.
