Solution Overview

Problem

Conventional swing analysis devices for golf clubs experience delays in reaction speed due to computation load and have limitations in accuracy, leading to discrepancies between analyzed and actual swing results.

Innovation Solution

A swing analysis device that measures motion data, generates swing analysis values, and transmits them directly to a user terminal for output, allowing for improved reaction speed and accuracy through calibration information received from the user terminal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the application program analyzes the sensor measurement value received from the swing analysis device, then the swing analysis can be performed, but a delay in reaction speed occurs due to computation load

Engineering Contradiction:

Improveswing analysis accuracyVSAvoidreaction speed delay

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent extracts the data analysis function from the user terminal application and relocates it to the swing analysis device. The analysis unit within the swing analysis device processes sensor measurement values and generates swing analysis values, which are then transmitted to the user terminal. This extraction eliminates the computation load from the terminal, resolving the reaction speed delay while maintaining analysis accuracy.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent inverts the traditional data processing architecture by having the swing analysis device (rather than the terminal application) perform the analysis function. Instead of the terminal receiving raw data and analyzing it, the terminal receives pre-analyzed swing analysis values generated by the swing analysis device's analysis unit, fundamentally reversing the processing flow to eliminate terminal computation delays.

Inventive Principle:

Principle #13The other way round (Inversion)

2Ease of operation

If conventional sensor modules are used in the swing analysis device, then the device can measure swing motions, but a difference between swing analysis value and actual swing result value occurs due to sensor accuracy limitations

Engineering Contradiction:

Improveswing measurement capabilityVSAvoidswing analysis accuracy

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The patent implements a feedback mechanism where the user terminal receives swing analysis values from the swing analysis device, allows user confirmation and calibration input, and transmits calibration information back to the device. The analysis unit uses this feedback to generate corrected swing analysis values, continuously improving measurement precision while maintaining ease of operation.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent changes the parameters of swing analysis values through calibration. When calibration information is received from the user terminal, the analysis unit adjusts the swing analysis values based on this information, transforming the parameters to align with actual swing results and eliminating accuracy discrepancies.

Inventive Principle:

Principle #35Parameter changes

3Device complexity

If the swing analysis device transmits only raw motion data to the user terminal, then data processing can be done centrally, but the reaction speed of the application program is slowed due to computation load

Engineering Contradiction:

Improvedata processing centralizationVSAvoidapplication program reaction speed

Core Design Contradiction:

Device complexityVSLoss of time

Solution Approach 1:

The patent extracts the computationally intensive data analysis function from the user terminal application and places it within the swing analysis device's analysis unit. This extraction leaves the terminal application with only simple display and calibration functions, eliminating computation load from the terminal and dramatically improving reaction speed while maintaining centralized processing capability in the swing analysis device.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

Proposed is a swing analysis device which includes a measurement unit which is coupled to a golf club of a user, and is configured to continuously measure motion data during swing motions of the golf club, an analysis unit configured to analyze the motion data continuously measured by the measurement unit to generate a swing analysis value, and a communication unit configured to transmit the swing analysis value generated by the analysis unit to a user terminal. According to the swing analysis device, as a swing analysis value generated based on motion data of the golf club is transmitted to a user terminal, the swing analysis value can be directly output by an application program installed in the user terminal without analyzing the motion data thus to greatly improve the reaction speed of the application program.
