Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional methods are used to evaluate golf swing stability, then data collection can provide comprehensive information, but the process becomes inefficient and impractical
Solution Approach 1:
The patent extracts the essential indicator for swing stability evaluation from extensive swing data. Instead of analyzing all collected swing data, the invention identifies and extracts a specific force indicator (representing force acting on the golfer's body) that directly correlates with swing stability, enabling efficient evaluation without comprehensive data collection
Solution Approach 2:
The patent introduces a force indicator as an intermediary parameter between the complex swing mechanics and the stability evaluation. This force indicator serves as a mediator that translates multiple swing parameters into a single measurable quantity that directly reflects swing stability, simplifying the evaluation process
2Loss of information
If comprehensive swing data is collected to understand stability factors, then accurate insights can be obtained, but the process becomes complex and resource-intensive
Solution Approach 1:
The patent extracts the critical stability-determining factor (force acting on the body) from complex swing mechanics. By focusing on this specific extracted parameter rather than analyzing all swing variables, the invention identifies stability factors accurately without requiring complex comprehensive data collection systems
Solution Approach 2:
The patent segments the complex swing evaluation process into distinct components: force calculation, stability evaluation, and factor identification. This segmentation allows each component to be handled separately and efficiently, reducing overall system complexity while maintaining identification accuracy

AI summary
Provided is a method of evaluating stability of a golf swing. The method comprises calculating a force indicator that represents a force that acts on a body of a golfer during the golf swing and evaluating stability of the golf swing according to a magnitude of the force indicator. In the calculating, the force indicator may be calculated during the golf swing made with a specific golf club, and in the evaluating, the stability of the golf swing may be evaluated as a characteristic of the specific golf club, in accordance with the magnitude of the force indicator.
