Strokes Gained Metric Using Gradient Map for Offline Shot Penalty
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current strokes gained metrics in golf analysis do not account for the severity of mishits and cannot be applied to terrains other than a golf course, limiting their use in practice or club fitting sessions.
Innovation Solution
A computer-implemented system that generates a performance metric using ball flight data from a tracking device, incorporating a variable penalty parameter defined by a gradient map to penalize offline shots differently based on their distance from the target, allowing for club selection recommendations on any terrain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fixed penalty parameter is applied to all offline shots, then the calculation is simple, but the evaluation accuracy is reduced because all mishits are treated equally regardless of severity
Solution Approach 1:
The patent applies local quality by implementing a gradient map where different regions have different penalty parameters. Shots that are further offline receive higher penalties while shots closer to the target line receive lower penalties. This creates a spatially varying penalty structure that accurately reflects the severity of different types of mishits, resolving the contradiction between evaluation accuracy and calculation complexity.
Solution Approach 2:
The patent introduces dynamics by making the penalty parameter variable rather than fixed. The penalty parameter dynamically adjusts based on the shot's position relative to the target line, allowing the evaluation system to adapt to different shot outcomes. This dynamic approach improves measurement precision while maintaining computational efficiency through the use of gradient map lookup tables.
2Adaptability or versatility
If the strokes gained metric is designed for golf courses only, then the calculation is straightforward, but the adaptability to other terrains is limited
Solution Approach 1:
The patent achieves universality by designing a penalty parameter system that can be applied to multiple terrain types including golf courses, driving ranges, and golf simulators. The gradient map approach provides a universal framework that adapts to different terrains by adjusting the penalty parameters according to the specific terrain characteristics, allowing the same core system to serve multiple functions across different environments.
Solution Approach 2:
The patent applies parameter changes by modifying the penalty parameters based on terrain type and conditions. The gradient map can be configured with different parameter sets for different terrains, allowing the system to adapt to varying conditions without changing its fundamental structure. This enables the system to maintain simplicity while achieving broad adaptability across golf courses, driving ranges, and simulators.
