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

This inventive concept extends the core technology of the original Triple Flexion Device to new applications and use cases, including athletic performance enhancement, balance and coordination improvement, robotic limb development, spinal cord injury rehabilitation, and fatigue reduction in repetitive tasks.

Background and Problem Solved

The original Triple Flexion Device addressed the limitations of existing devices in facilitating hip, knee, and ankle flexion during the swing phase of walking, particularly for individuals with paralysis of the lower extremity. However, its potential applications were limited to the medical field. The new inventive concept solves the problem of restricted applicability by adapting the core technology to diverse industries, unlocking its full potential.

Detailed Description of the Inventive Concept

The new inventive concept involves the adaptation of the Triple Flexion Device's core technology to various industries and use cases. For athletic performance enhancement, the device is designed to facilitate flexion of at least three joints during a stride, providing athletes in high-impact sports with improved mobility and agility. For balance and coordination improvement, the device is worn on a limb, providing hip, knee, and ankle flexion during a swing phase of movement. In robotic limb development, the triple flexion mechanism is adapted to provide hip, knee, and ankle flexion in a robotic leg, controlled by a microprocessor. For spinal cord injury rehabilitation, the device is configured to provide hip, knee, and ankle flexion during a swing phase of walking, controlled by an electroencephalography (EEG) interface. Finally, for fatigue reduction in repetitive tasks, the device is powered by a piezoelectric material, providing hip, knee, and ankle flexion during a swing phase of movement.

Novelty and Inventive Step

The new inventive concept's novelty lies in its adaptation of the Triple Flexion Device's core technology to diverse industries and use cases, which was not originally considered. The inventive step is the recognition of the potential for this technology to be applied beyond the medical field, combined with the specific design and implementation details for each new application.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include variations in the wearable device's design, materials, and control systems. For example, the device could be integrated into clothing or shoes, or use artificial intelligence to adapt to individual users' needs. Additionally, the core technology could be applied to other joints or limbs, or used in conjunction with other assistive technologies.

Potential Commercial Applications and Market

The new inventive concept has significant commercial potential across various industries, including sports equipment, healthcare, robotics, and manufacturing. The target market includes athletes, individuals with spinal cord injuries, robotic developers, and companies seeking to improve worker productivity and reduce fatigue.
