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. 11,857,395.

Summary of the Inventive Concept

An advanced wearable device that facilitates triple flexion of the hip, knee, and ankle joints during the swing phase of walking, providing real-time feedback, improved adjustability, and enhanced safety features.

Background and Problem Solved

The original triple flexion device, while effective, has limitations in terms of adjustability, real-time feedback, and safety features. The new inventive concept addresses these limitations by incorporating sensors, modular design, and pressure-sensing systems, enabling a more efficient, safer, and personalized triple flexion assistance experience.

Detailed Description of the Inventive Concept

The enhanced triple flexion device consists of a wearable device with adjustable, high-tension elastic bands that facilitate hip, knee, and ankle flexion. The waist belt features a V-shaped design to reduce pressure on the lower back. The device incorporates sensors to monitor the user's walking pattern and adjust the elastic band tension accordingly, providing real-time feedback and optimization. A modular design with interchangeable elastic bands of varying tension and a quick-release mechanism enables easy adjustments. Additionally, a user profiling module captures individual gait patterns and generates customized elastic band tension settings for optimal flexion assistance. A pressure-sensing system detects excessive force on the user's joints and automatically adjusts the elastic band tension to prevent injury.

Novelty and Inventive Step

The new claims introduce novel features such as real-time feedback, modular design, and pressure-sensing systems, which are not present in the original patent. These features provide a significant improvement over the existing device, making the new inventive concept non-obvious and innovative.

Alternative Embodiments and Variations

Alternative embodiments of the enhanced triple flexion device could include variations in the sensor technology, modular design, and pressure-sensing systems. For example, the device could utilize artificial intelligence-powered sensors to predict and adapt to changes in the user's gait pattern. The modular design could be modified to accommodate different types of elastic bands or materials. The pressure-sensing system could be integrated with other safety features, such as alerts or warnings, to provide an additional layer of protection.

Potential Commercial Applications and Market

The enhanced triple flexion device has significant commercial potential in the healthcare and rehabilitation industries, particularly in the areas of physical therapy, orthotics, and prosthetics. The device could be marketed to individuals with mobility impairments, such as those with paralysis or stroke victims, as well as to athletes and individuals who require additional support during exercise or physical activity.
