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. 11,857,832.

Summary of the Inventive Concept

An improved body stretching system designed to provide enhanced safety, efficiency, and user experience through innovative features such as adjustable main body, pressure sensor, real-time feedback, and wireless connectivity.

Background and Problem Solved

The original body stretching system, while beneficial, had limitations such as fixed main body size, lack of force detection, and limited user feedback. The new inventive concept addresses these limitations by introducing an adjustable main body, pressure sensor, and real-time feedback module, ensuring a safer and more efficient stretching experience.

Detailed Description of the Inventive Concept

The enhanced body stretching system comprises a limb stretching unit with an adjustable main body to accommodate users of varying sizes. The gripping structure is designed to removably connect to a first limb of a user and includes a pressure sensor to detect excessive force application. A ratchet assembly disposed within at least a second portion of the main body is designed to automatically release when a predetermined force threshold is exceeded. Additionally, the system features a real-time feedback module that provides audio or visual alerts to the user when the stretching exercise is being performed incorrectly or when the user has reached a predetermined level of flexibility. A method for using the body stretching system involves setting a desired stretching goal, tracking progress towards the goal, and providing personalized recommendations for adjusting the stretching routine based on the user's progress.

Novelty and Inventive Step

The new inventive concept introduces several novel features, including the adjustable main body, pressure sensor, real-time feedback module, and wireless connectivity, which collectively provide an enhanced stretching experience. The automatic release of the ratchet assembly and the provision of personalized recommendations based on user progress are particularly non-obvious and innovative aspects of the new claims.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include variations in the design of the gripping structure, the type of sensors used, or the integration of artificial intelligence to provide more personalized feedback. Additionally, the system could be adapted for use in different therapeutic or athletic settings, such as physical therapy clinics or professional sports teams.

Potential Commercial Applications and Market

The enhanced body stretching system has significant commercial potential in the health and wellness industry, particularly in the areas of physical therapy, athletic training, and personal fitness. The system's advanced safety features and user-friendly design make it an attractive option for individuals and organizations seeking to improve flexibility and reduce injury risk.
