Solution Overview

Problem

Golfers face challenges in accurately estimating the distance and direction of their shots, leading to incorrect club selection and potential hazards, and existing systems lack real-time prediction of shot outcomes and putt breaks.

Innovation Solution

A golf player aid system using a cellular phone with GPS and graphical display to predict the result of non-putting strokes, provide putt break information, and automatically collect data via telemetry-equipped clubs, allowing for real-time club selection and hazard avoidance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If golfers rely on memory and skill to estimate distances and choose clubs, then they can play without external devices, but accuracy in club selection and distance estimation deteriorates

Engineering Contradiction:

Improvedistance estimation accuracyVSAvoiddependency on external systems

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The system enables self-service by automatically collecting shot data, calculating performance metrics, and providing real-time feedback without requiring external caddies or complex manual tracking. The portable device serves the player's needs for distance and accuracy information independently.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual memory-based estimation with electronic data collection and processing. Telemetry equipment automatically measures shot distances and outcomes, substituting human cognitive estimation with precise electronic measurement and calculation systems.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If golfers use professional caddies for distance and strategy advice, then decision accuracy improves, but cost and complexity increase

Engineering Contradiction:

Improveclub selection accuracyVSAvoidsystem structure

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The system empowers players to become their own caddies by providing automated distance measurement, shot outcome tracking, and performance analysis. The portable device delivers caddy-like functionality through electronic computation rather than human expertise.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent substitutes human caddies with an electronic data processing system that automatically collects telemetry data, calculates statistical performance metrics, and provides real-time club selection recommendations based on objective measurements rather than human judgment.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Quantity of substance

If golfers manually record each stroke data, then data collection is possible, but time consumption and ease of operation worsen

Engineering Contradiction:

Improveshot data collectionVSAvoiddata recording effort

Core Design Contradiction:

Quantity of substanceVSEase of operation

Solution Approach 1:

The telemetry-equipped clubs perform automatic data collection without player intervention. The system self-records shot distances, club identities, and outcome positions, eliminating the need for manual note-taking while comprehensively tracking all relevant shot parameters.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual data recording with automated electronic telemetry systems embedded in the clubs. Sensors and transmitters automatically capture and transmit shot data to the portable device, substituting human writing or note-taking with electronic data acquisition.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Loss of time

If existing systems provide post-round analysis only, then data processing is simplified, but real-time decision support is lost

Engineering Contradiction:

Improvefeedback timingVSAvoiddata processing capability

Core Design Contradiction:

Loss of timeVSDevice complexity

Solution Approach 1:

The system performs preliminary calculations of performance metrics and probability forecasts during play, preparing club selection recommendations in advance. The portable device continuously processes telemetry data to predict likely outcomes before the player makes their next shot decision.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements real-time feedback by displaying calculated performance metrics, distance estimates, and outcome probabilities to the player during round play. The system processes telemetry data continuously and provides immediate feedback on shot performance and club selection recommendations.

Inventive Principle:

Principle #23Feedback

AI summary

A method of using a computing device to forecast the result of a golf stroke and a portable handheld device for collecting and displaying golf round data are provided. The data collected for each stroke includes the location, time, and club used and the resulting ball position achieved” Before each drive or approach shot player skill level, course layout information, and player location on the course are used together with the club selected by the player to forecast the result of the next stroke. Putt break prediction information is provided before each putt. Information that a stroke has been taken and which dub was used can be entered manually or sensed automatically from telemetry equipped clubs.
