Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for determining a golfer's lie angle at address are inaccurate and time-consuming, particularly for short-game shots, as they rely on subjective measurements or dynamic motion sensors that fail to precisely match the club's lie angle with the player's swing characteristics.
Innovation Solution
A system using a portable electronic device with a gyroscope and accelerometer to measure a golfer's lie angle at address, providing a color code recommendation for clubs calibrated to the player's specific lie angle, ensuring accurate club fitting by locking in on the golfer's static position and providing audio and visual feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dynamic motion sensors are used to determine lie angle, then player-specific swing characteristics can be analyzed, but measurement precision for lie angle at address deteriorates
Solution Approach 1:
The system performs preliminary measurement of the lie angle at address position before the swing occurs. Sensors are positioned on the club to capture the static address position data in advance, allowing the lie angle to be determined before motion begins, thus ensuring measurement precision while still enabling player-specific analysis.
Solution Approach 2:
The system transitions from purely dynamic motion sensing to a hybrid approach that captures both static address position data and dynamic swing data. By measuring the lie angle at the static address position and combining it with dynamic swing characteristics, the system achieves both measurement precision and adaptability to player-specific swings.
2Measurement precision
If still images or physical tools are used to estimate lie angle, then measurement can be performed, but time consumption increases and measurement precision deteriorates
Solution Approach 1:
The system replaces manual physical tools and subjective visual estimation with electronic sensors and automated image processing. Cameras and sensors automatically capture and analyze the club's address position, eliminating the need for time-consuming manual measurements while improving measurement precision through objective digital analysis.
Solution Approach 2:
The system performs self-measurement by automatically capturing images and calculating lie angle data without requiring external physical tools or subjective human judgment. The automated processing of sensor data and images enables rapid, precise measurement that eliminates both time consumption and precision errors associated with manual methods.
3Reliability
If subjective determination of address position is used, then lie angle can be estimated, but measurement precision deteriorates due to reliability issues
Solution Approach 1:
The system uses feedback from multiple sensors and camera systems to objectively detect and verify the address position. By continuously monitoring sensor data and comparing it against predetermined criteria for proper address position, the system eliminates subjective determination and ensures both reliability and measurement precision through automated feedback loops.
