Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If detailed swing parameters are displayed, then measurement precision is improved, but ease of operation deteriorates because general players cannot understand the parameters
Solution Approach 1:
The patent applies color-coded visual feedback to represent swing quality. Different colors indicate different evaluation results, allowing players to quickly understand their swing performance without needing to interpret complex numerical parameters. This transforms precise measurement data into intuitive visual information that general players can easily comprehend.
Solution Approach 2:
The system creates visual copies or representations of the actual swing path and form through graphical overlays and animations. These visual copies help players understand their swing mechanics by comparing their performance against ideal swing models, making complex swing parameters accessible to players without specialized knowledge.
2Reliability
If comprehensive swing analysis is provided, then reliability is improved, but device complexity increases due to multiple sensors and processing requirements
Solution Approach 1:
The patent makes the user terminal device universal by enabling it to perform multiple functions: capturing swing motion, analyzing trajectory, evaluating performance, and providing visual feedback. A single device handles all these tasks, avoiding the need for separate specialized equipment for each function while maintaining comprehensive analysis reliability.
Solution Approach 2:
The system enables the user terminal to analyze and evaluate swings independently without requiring external specialized equipment or complex multi-device configurations. The device serves itself by integrating all necessary sensing, processing, and feedback capabilities within a single unit that players already possess.
3Ease of operation
If visual feedback is provided to help players understand swing correctness, then ease of operation is improved, but loss of information increases due to simplification of data presentation
Solution Approach 1:
Color-coded indicators provide visual feedback that conveys swing evaluation results intuitively while preserving the underlying detailed parameter data. The color system serves as a simplified interface layer that does not replace but complements the comprehensive data collection, allowing players to quickly grasp performance quality without losing access to detailed swing parameters when needed.

AI summary
Provided is a golf swing analysis system, a golf swing analysis method, and a program enabling a player to easily grasp whether the player has made a correct swing. A captured video image obtaining unit (70) obtains a captured video image in which a player making a golf swing is captured. A swing path type specifying unit (86) specifies at least one reference angle based on at least one of a position of a predetermined body part of the player at address or a position of a shaft at address, where the positions are specified based on the captured video image. A swing path type specifying unit (86) specifies a downswing angle of a club head captured in a captured video image based on the captured video image. The swing path type specifying unit (86) compares the reference angle with the downswing angle.
