Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a radar sensor is used to analyze golf ball flight and trajectory, then the device can provide swing analysis values, but the measurement precision is insufficient leading to differences between analysis values and actual results
Solution Approach 1:
The patent implements a feedback mechanism where the system receives actual swing result data from user terminals (such as mobile devices with GPS or other sensing capabilities) and uses this feedback to iteratively improve and calibrate the radar sensor's measurement algorithms, thereby reducing the gap between analyzed values and actual results
Solution Approach 2:
The system dynamically adjusts radar sensor parameters and analysis algorithms based on received calibration data from multiple users and various swing conditions, optimizing measurement precision by changing operational parameters to match real-world performance characteristics
2Measurement precision
If the device requires actual golf ball hitting to generate accurate swing analysis values, then measurement precision improves, but the ease of operation decreases as users cannot practice without balls
Solution Approach 1:
The system performs preliminary calibration actions by collecting and processing swing data during actual golf ball hitting sessions, storing calibrated parameters and patterns that can then be applied to subsequent analysis sessions where no golf ball is present, enabling accurate analysis without requiring physical balls
Solution Approach 2:
The system creates digital copies or models of actual swing mechanics and ball flight patterns through sensor data and calibration information, allowing users to practice and analyze swings without physical golf balls by simulating the experience through virtual representations

AI summary
Proposed is a golf analysis device with a calibration function, which includes a sensor unit configured to generate tracking data for at least one of a golf club moving by a user's swing motion and a golf ball hit by the user's swing motion; an analysis unit configured to generate a swing analysis value of the user by analyzing the tracking data; and a communication unit configured to transmit the swing analysis value to a user terminal, and receive calibration information on the swing analysis value from the user terminal. As a swing analysis value can be generated based on the calibration information received from the user terminal, the golf analysis device allows the user to receive very accurate swing analysis results.
