Solution Overview

Problem

Existing golf swing analysis devices primarily display results using numerical data, making it difficult for users to grasp the actual swing analysis, including the state of the swing.

Innovation Solution

A swing analysis device that acquires a video of the user's swing, processes it to determine impact timing and tempo, and displays the video along with tempo information, allowing users to visualize their swing and analyze their technique effectively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If only numerical data is displayed for swing analysis, then data presentation is simple, but user understanding of actual swing state is difficult

Engineering Contradiction:

Improveswing state informationVSAvoiddisplay system complexity

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The patent combines the swing video display and numerical data display into a single integrated display interface. The video playback area shows the actual swing motion while the numerical data area simultaneously presents analyzed metrics, allowing users to correlate visual observations with quantitative measurements without needing separate display systems.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces a timing marker as an intermediary element that bridges the video playback and numerical data. The marker indicates the specific moment in the swing sequence when the numerical data was captured, helping users understand the temporal relationship between the visual swing state and the measured parameters.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Loss of information

If multiple data elements are displayed simultaneously, then comprehensive information is provided, but user distraction increases

Engineering Contradiction:

Improveswing analysis informationVSAvoiduser distraction

Core Design Contradiction:

Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The display is segmented into distinct functional areas: a video playback area for visual swing observation, a numerical data area for quantitative metrics, and a timing marker area for temporal reference. This spatial segmentation allows comprehensive information presentation while reducing cognitive load by organizing data into logically grouped sections rather than a cluttered uniform display.

Inventive Principle:

Principle #1Segmentation

3Duration of action of moving object

If swing video is played continuously, then complete swing sequence is shown, but impact timing emphasis is lost

Engineering Contradiction:

Improvevideo playback durationVSAvoidimpact timing precision

Core Design Contradiction:

Duration of action of moving objectVSMeasurement precision

Solution Approach 1:

The system uses periodic timing markers that appear at regular intervals during video playback, with special emphasis on the impact timing marker. This periodic indication system maintains continuous video playback while periodically drawing user attention to critical moments, particularly the impact phase, without requiring pauses or repetitions of the entire swing sequence.

Inventive Principle:

Principle #19Periodic action

AI summary

A swing analysis device includes: an acquisition unit (swing video acquisition unit) acquiring a swing video of a user; a processing unit deciding an impact timing and a tempo, based on the swing video; and a display unit displaying the swing video and the tempo. The display unit, while displaying the swing video, displays the tempo when the impact timing is reached in the swing video.
