Golf Swing Diagnosis Apparatus Impact Angle Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf swing diagnosis systems struggle to clearly display the features of a swing before impact, making it difficult to understand and evaluate the swing performance effectively.
Innovation Solution
A swing diagnosis apparatus that calculates a level based on the relationship between the incidence angle and inclination of the ball hitting portion of a golf club or similar exercise appliance at impact, using data from inertial sensors to grade and visually represent the swing features, including incidence angle, inclination, speed, and trajectory curvature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a radar chart is used to display ball movement data, then the ball flight performance can be visualized, but the swing features before impact cannot be clearly understood
Solution Approach 1:
The patent segments the swing analysis into distinct components: incidence angle, inclination, speed, and trajectory curvature. Each parameter is calculated and displayed separately, allowing users to understand specific swing features before impact without being overwhelmed by a single complex radar chart representation.
Solution Approach 2:
The patent transitions from a two-dimensional radar chart to a multi-dimensional analysis by calculating and displaying multiple independent parameters (incidence angle, inclination, speed, curvature). This adds depth to the analysis, enabling comprehensive understanding of swing features that cannot be captured in a single radial representation.
2Loss of information
If multiple parameters are calculated and displayed, then swing features can be comprehensively analyzed, but the device complexity increases
Solution Approach 1:
The patent employs a single level calculation section that performs multiple functions: calculating incidence angle, inclination, speed, and trajectory curvature from the same input data. This multi-functional approach comprehensively analyzes swing features without requiring separate complex systems for each parameter.
Solution Approach 2:
The patent transforms raw sensor data into multiple meaningful parameters through systematic calculations. By changing the form of data representation from raw measurements to derived parameters (angles, speeds, curvatures), the system achieves comprehensive analysis while maintaining manageable complexity through standardized calculation procedures.

AI summary
A swing diagnosis apparatus includes a level calculation section that calculates a level on the basis of a relationship between an incidence angle of a ball hitting portion of an exercise appliance at impact, and an inclination of the ball hitting portion of the exercise appliance at impact.
