Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If launch monitors with radar technology are used to measure golf swing parameters, then measurement precision is improved, but device cost increases significantly
Solution Approach 1:
The patent uses visual images from standard cameras as copies of the golf swing motion, processing these image copies through computer vision algorithms to extract swing parameters. This replaces the need for expensive radar equipment while achieving comparable measurement precision through computational analysis of visual data.
Solution Approach 2:
The patent substitutes the mechanical/radar-based measurement system with a computational vision system. Instead of using physical radar sensors to directly measure club head speed and position, the system uses image processing algorithms to analyze visual data and calculate the same parameters, thereby reducing hardware costs while maintaining measurement accuracy.
2Measurement precision
If professional feedback from golf instructors is obtained, then measurement precision is improved, but device cost increases
Solution Approach 1:
The system enables golfers to self-analyze their swings using the automated image processing system. The computer vision algorithm automatically extracts swing parameters and provides feedback without requiring professional instructors, allowing golfers to independently obtain precise swing analysis and improvement guidance.
Solution Approach 2:
The patent implements an automated feedback mechanism where the system analyzes swing images, compares them against optimal swing patterns, and provides immediate feedback to the golfer. This automated feedback loop replaces the need for expensive professional instruction while maintaining the ability to identify and correct swing flaws.
3Measurement precision
If high resolution image capture is used to analyze golf swing, then measurement precision is improved, but device cost increases
Solution Approach 1:
The patent changes the parameter of image resolution requirement by demonstrating that standard resolution images are sufficient when processed with advanced computer vision algorithms. The system extracts meaningful swing parameters from standard images through sophisticated image processing, eliminating the need for expensive high-resolution capture equipment while maintaining analysis precision.
Data Source
AI summary
A method and system for using a low resolution image of a golfer's swing for analysis is disclosed. Cameras obtain images of various portions of a golfer's swing. A computer calculates parameters associated with a golfer and a golf club from the images. Parameters include body angles, head position, shoulder positions, arm positions, hand positions, leg positions, foot positions, club shaft angles, and club head position. Different portions of the swing are captured using the cameras, including a static initial address, a backswing, a downswing, a forward swing, and a follow-through. A computer uses measured parameters from two or more portions of the swing to determine comparative parameters during different portions of the swing. The computer uses the parameters to generate swing analysis outputs, including swing characteristic information and/or swing profile information. A correlation table relates identified swing analysis outputs to recommendations to the golfer to improve the swing.
