This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,855.

Summary of the Inventive Concept

This inventive concept presents a suite of improvements and enhancements to the original racket head characterization method, enabling real-time visualization, automated inspection, and design optimization for ball game racket frames.

Background and Problem Solved

The original patent for characterizing a ball game racket frame has limitations in terms of manual data processing, lack of real-time visualization, and limited design optimization capabilities. This new inventive concept addresses these limitations by introducing automated data processing, real-time graphical representation, and machine learning-based design optimization.

Detailed Description of the Inventive Concept

The enhanced racket head characterization system comprises a data processing unit, a graphical representation unit, and a sensor for capturing racket head contour data. The system automatically determines parameters characterizing the racket head shape and visualizes the racket head contour and deviation from a circular shape in real-time. Additionally, the system can analyze the racket head contour using a plurality of racket head contour segments and generate design recommendations to minimize deviation from a circular shape. The system can also classify racket head contour segments based on deviation from a circular shape using a machine learning model and generate a report indicating the classification results.

Novelty and Inventive Step

The new claims introduce the concept of real-time visualization, automated inspection, and machine learning-based design optimization, which are not present in the original patent. The use of a sensor for capturing racket head contour data and the application of machine learning models for classification and design optimization are novel and non-obvious improvements over the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include the use of different types of sensors, such as 3D scanners or cameras, to capture racket head contour data. Additionally, the system could be adapted for use with different types of ball game racket frames, such as tennis or squash rackets. The machine learning model could also be trained on different datasets to optimize performance for specific racket head designs.

Potential Commercial Applications and Market

The enhanced racket head characterization and optimization system has significant commercial potential in the sports equipment industry, particularly in the development and manufacturing of high-performance ball game racket frames. The system could be marketed as a tool for racket manufacturers to optimize their designs, improve product quality, and reduce production time and costs.
