Solution Overview
Problem
Current golf club fitting methods rely heavily on experience and intuition, leading to subjective and inconsistent results in determining the optimal swingability index for golfers, as they do not objectively consider various swingability indices beyond club weight.
Innovation Solution
A fitting apparatus that includes an acquisition unit for measuring swing actions, a calculation unit to determine swing indices such as energy or torque exerted during the swing, and a determination unit to objectively calculate the optimal swingability index, using correspondence data to match the index with suitable golf clubs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fitting methods depend on experience and intuition, then the fitting process is simple and quick, but the fitting results are subjective and inconsistent
Solution Approach 1:
The patent replaces the mechanical system of human experience and intuition with an automated measurement and calculation system. The measurement device objectively measures swing actions, and the calculation unit computes swing indices according to predetermined formulas, eliminating subjective judgment while maintaining operational simplicity through automation.
Solution Approach 2:
The system enables self-service fitting by allowing the measurement device and calculation unit to automatically determine swing indices without requiring expert intervention. The golfer simply performs swing actions that are automatically measured and analyzed, providing consistent results through the system's inherent measurement and calculation capabilities.
2Device complexity
If only club weight is considered for fitting, then the fitting process is straightforward, but multiple swingability indices are not considered
Solution Approach 1:
The patent segments the overall swingability assessment into multiple distinct indices (arm energy, shoulder torque, head speed, etc.), each measured and calculated separately. This segmentation allows comprehensive evaluation of different swing characteristics while maintaining clear, organized data processing for each individual index.
Solution Approach 2:
The measurement device and calculation system are designed with multi-functionality to handle various types of swingability indices simultaneously. The system can measure and calculate multiple different indices using a unified measurement and calculation framework, making the fitting process versatile without proportionally increasing complexity.
3Measurement precision
If multiple swingability indices are measured and calculated, then the fitting accuracy is improved, but the measurement and calculation complexity increases
Solution Approach 1:
The patent replaces complex manual measurement and calculation processes with automated electronic measurement devices and computational algorithms. The measurement device automatically captures swing data, and the calculation unit computes multiple swing indices according to predetermined formulas, achieving high measurement precision while keeping the system complexity manageable through automation.
Solution Approach 2:
The system measures and calculates multiple different parameters (arm energy, shoulder torque, head speed, etc.) to comprehensively characterize swingability. By changing from a single parameter approach to multiple parameters, the system achieves higher determination accuracy while using a unified measurement and calculation framework that manages complexity.
