Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a dedicated measuring device is used to capture head images near impact, then measurement precision is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent uses image processing to create a virtual copy of the club head position and trajectory from standard camera footage, eliminating the need for specialized measuring devices. The system extracts club head information by analyzing the relationship between the club head, ball, and camera position through computational geometry, thereby achieving precise measurement without dedicated hardware.
Solution Approach 2:
The patent replaces mechanical measuring devices with an optical and computational system. Instead of using physical sensors or specialized cameras mounted on the club, the system uses standard cameras combined with image processing algorithms to calculate club head trajectory, position, and orientation through mathematical models.
2Measurement precision
If a dedicated measuring device is used for golf swing analysis, then analysis accuracy is improved, but ease of operation deteriorates
Solution Approach 1:
The system enables players to perform self-analysis using their own smartphones or tablets. The application automatically captures images during the swing, processes the data locally or remotely, and provides immediate feedback on swing mechanics, eliminating the need for professional analysis equipment or expert intervention.
Solution Approach 2:
The patent makes the analysis system universally applicable by using standard smartphone cameras and processing capabilities that any player already possesses. The system works on various device types and can be used by players of any skill level, making the technology accessible without requiring specialized equipment.
3Measurement precision
If specialized equipment is used for golf swing analysis, then measurement precision is improved, but adaptability deteriorates
Solution Approach 1:
The system creates a virtual measurement model that can be applied in any physical location. By using image processing to reconstruct the club head trajectory and impact parameters from standard camera views, the system adapts to different environments whether at the golf course, practice range, or home, without requiring location-specific equipment.
Solution Approach 2:
The system adjusts its measurement parameters and computational models to accommodate different shooting positions, camera angles, and environmental conditions. The image processing algorithms dynamically adapt to varying geometric relationships between the camera, club head, and ball, enabling precise measurement across diverse locations.
