Description:FIELD OF THE INVENTION

[0001] The present invention relates to a therapeutic stretching exercise and rehabilitation device that enhances visually impaired individual’s mobility by detecting obstacles in real-time and providing immediate feedback to guide them safely, thereby reducing the risk of collisions and ensuring independent navigation in various environments.

BACKGROUND OF THE INVENTION

[0002] Stretching exercises is necessary for visually impaired individuals who face several challenges during exercising and mobility rehabilitation. A primary concern is ensuring safety; without visual cues, they struggle to detect obstacles or hazards in their environment, increasing the risk of injury. This necessitates exercising in secure, familiar settings, often with a partner or under supervision. Additionally, the lack of visual feedback makes it difficult to perform exercises with correct form, potentially leading to ineffective routines or strain. Access to appropriately equipped facilities also be limited, as navigating unfamiliar gym layouts poses challenges. Moreover, the psychological impact of visual impairment, such as reduced confidence or fear of injury, deter individuals from engaging in regular physical activity. To address these issues, suitable exercise programs that emphasize tactile feedback, clear verbal instructions, and the use of assistive devices are essential to enhance safety and effectiveness.

[0003] Traditionally, individuals with visual impairments have utilized various methods to enhance mobility and perform stretching exercises. Orientation and Mobility (O&M) training is fundamental, teaching techniques such as the use of white canes for obstacle detection and navigation, thereby promoting independence and safety. Incorporating physical activities like tai chi, yoga, and dance has been shown to improve balance and mobility in visually impaired individuals. These activities often rely on audio-tactile cues and personalized instruction to ensure proper technique and safety. Additionally, seated dynamic stretch workouts have been adapted to accommodate various abilities, providing accessible exercise options that enhance flexibility and joint mobility. Overall, these traditional methods combine structured training with adapted physical activities to support the mobility and well-being of visually impaired individuals.

[0023] The present invention relates to a therapeutic stretching exercise and rehabilitation device that improves navigation and stability by dynamically responding to changes in the user's walking pattern. Additionally, the device enhances user safety by preventing accidental falls, detecting environmental hazards, and ensuring better interaction with surroundings, thereby providing an improved and secure walking experience.

[0024] Referring to Figure 1, an isometric view of a therapeutic stretching exercise and rehabilitation device is illustrated, comprising a rectangular base 101 configured with a telescopic rod 102, a pair of rectangular-plates 103 are attached with the base 101, an artificial intelligence based imaging unit 104 installed on the base 101, a primary motorized drawer arrangement 105 integrated within each of the plates 103, a pair of handles 106 are attached with a rectangular bar 107 installed over the rod 102, a hydraulic piston 108 integrated with a primary motorized ball-and-socket joint 109 installed in between the base 101 and each of the plates 103, a motorized sliding unit 110 installed along length of the rectangular base 101, a holographic projection unit 111 provided on the base 101, a L-shaped telescopic link 112 installed on lateral side of the base 101, configured to store multiple weight blocks 113, the link 112 is connected to base 101 via a motorized ball-and-socket joint 114, a motorized slider 115 arranged along the periphery of the link 112, pairs of clamping units 116 are provided to the slider 115, a pair of hand-supporting flaps 117 are connected to the bar 107 through motorized hinges 118, the hand-supporting flaps 117 are equipped with a secondary motorized drawer arrangement 119, a secondary motorized ball-and-socket joint 120 is integrated between the base 101 and the rod 102, a thermal camera 121 is integrated with the base 101 and an electronic nozzle 122 is connected with a vessel 123 stored with medicinal liquid and configured on the bar 107.

[0025] The device disclosed herein comprises a rectangular base 101 designed to assist users in performing stretching exercises, specifically targeting the calf muscles of the lower limbs. The base 101 equipped with a telescopic rod 102 developed to be positioned on a fixed surface. A pair of rectangular plates 103 are attached to the base 101, and the user places their feet on these plates 103 to attain a standing posture over the base.

[0026] To facilitate personalized stretching, the device includes an inbuilt user-interface within a computing unit. The interface enables the user to input details regarding the type of stretching exercise they wish to perform. The user’s foot dimensions are detected through an artificial intelligence-based imaging unit 104 installed on the base 101 to capture multiple images of the surroundings. The microcontroller, linked to the computing unit, processes the input commands and activates the imaging unit 104 to capture and analyze the foot’s dimensions.

[0027] The artificial intelligence based imaging unit 104 is constructed with a camera lens and a processor, wherein the camera lens is adapted to capture a series of images of the surrounding. The processor carries out a sequence of image processing operations including pre-processing, feature extraction, and classification by utilizing artificial intelligence and machine learning protocols. The image captured by the imaging unit 104 is real-time images of the surrounding. The artificial intelligence based imaging unit 104 in communication with a microcontroller. The artificial intelligence based imaging unit 104 transmits the captured image signal in the form of digital bits to the microcontroller. The microcontroller upon receiving the image signals compares the received image signal with the pre-fed data stored in a database and constantly determines foot’s dimensions.

[0028] The microcontroller then adjusts the footplates 103 dimensions using a primary motorized drawer arrangement 105 integrated in the plates 103 to ensure a customized fit for optimal support. The drawer arrangement consists of a drawer that typically slides on the rails inside the plate. These rails provide a smooth and stable path for the compression and expansion of the plate. When the microcontroller actuates the drawer arrangement, the motor starts rotating and the rotational motion is converted into linear motion through the use of gears. As the motor rotates, the drawer moves either outward or inward along the sliding rails. This expansion and compression increase and decreases the size of the plate and ensures a customized fit for optimal support.

[0029] An ultrasonic sensor installed on the base 101 that detects the user's height. The microcontroller, upon receiving this data, regulates the telescopic rod 102 to position two rectangular bars 107 with attached handles 106 at an optimal height from the ground. This arrangement ensures stability and balance for the user while performing the exercises. The ultrasonic sensor emits high-frequency waves toward the user and measures the time it takes for the waves to bounce back after hitting the user. The sensor is typically oriented in a way that it measures the height of the user. The ultrasonic sensor collects a significant amount of data by scanning the entire surface of the user and forms a 3D point cloud, which represents the height of the user. The ultrasonic sensor sends the data to a microcontroller which processes the acquired data and detects the height of the user.

[0030] For vertical and angular adjustments of the foot plates 103, a hydraulic piston 108 is integrated with the primary motorized ball-and-socket joints 109 positioned between the base 101 and each plate 103 to provide smooth and controlled adjustments, adapting the foot plates’ 103 position for a variety of stretches. The hydraulic piston 108 is linked with a hydraulic unit which comprises an oil compressor, cylinders, oil valves and piston 108 that works in collaboration for vertical adjustments of the foot plates 103.

[0031] The motorized ball and socket joint 109 consists of a ball-shaped element that fits into a socket, which provides rotational freedom in various directions. The ball is connected to a motor, typically a servo motor which provides the controlled movement. The footplate 103 is attached to the socket of the motorized ball and socket joint 109. The motor responds by adjusting the ball and socket joint 109 and rotates the ball in the desired direction, and this motion is transferred to the socket that holds the footplates 103 to provide smooth and controlled adjustments.

[0032] A motorized sliding unit 110 is mounted along the length of the rectangular base 101, which allows for individual position adjustment of the plates 103 based on specific stretching exercises and user preferences. The motorized sliding unit 110 consists of a motor, and a rail unit integrated with ball bearings to allow smooth linear movement. As the motor rotates the rotational motion of the motor is converted into linear motion through a pair of belts and linkages. This linear motion provides a stable track and allows the plates 103 to move and adapt with different stretch exercises and user preferences.

[0033] An angle sensor, synchronized with the imaging unit 104, detects the user’s body angle during the stretch. The angle sensor used herein is preferably an optical angle sensor that use light beams and optical detectors to measure changes in light reflection or transmission caused by the angle of the user’s body. As the angle changes, the amount of light reflected or transmitted varies, allowing the sensor to calculate the angle. The angle sensor provides an output signal to the microcontroller that represents the detected angle of the user’s body.

[0034] If an anomaly in the user’s posture is detected, the microcontroller activates a holographic projection unit 111 to visually guide the user in adjusting their posture, ensuring correct alignment during the exercise. On actuation of holographic projection unit 111 by the microcontroller, the light source emits various combination of lights towards the lens which is further portrayed depicting an appropriate posture.

[0035] An L-shaped telescopic link 112 is mounted on the lateral side of the base 101, designed to store multiple weight blocks 113. This link 112 is motorized and adjusts based on commands from the microcontroller. The link 112 mentioned herein is powered by a pneumatic unit that utilizes the compressed air to extend or retract the link. The horizontal arm of the link 112 is positioned over the user's thigh, with motorized ball-and-socket joints allowing precise angle adjustments. The link 112 moves along a motorized slider 115, enabling the user to adjust the placement of the weight blocks 113 via voice commands issued through an integrated microphone.

[0036] The microphone plays a crucial role by converting spoken words or commands into electrical signals which are then processed and analyzed to trigger specific actions. When the user speaks or commands, their vocal cords vibrate, creating sound waves. These sound waves travel through the air as variations in air pressure. The microphone mentioned herein is a transducer that converts these variations in air into electric signals. The analog electrical signal is converted into digital form which is done by an analog-to-digital converter (ADC). The digital signal is then subjected to various signal processing techniques to enhance voice quality and eliminate noise.

[0037] Multiple clamping units 116 are installed on the motorized slider 115 that securely hold the weight blocks 113 during use. These units ensure stability and safety during exercises requiring weight resistance, providing an effective workout while maintaining user safety. The clamping unit includes a pair of flaps 117 which are pivoted with each other for allowing the axial motion of the flaps 117 required for clasping the weight blocks 113, a DC motor is paired with the pivot joint that is activated by the microcontroller for providing a rotational motion to the joint for automating the movement of the flaps 117 for gripping the blocks 113.

[0038] Additionally, a pair of hand-supporting flaps 117 are attached to the rectangular bar 107. These flaps 117 are connected via motorized hinges 118 and adjust based on the exercise and user’s hand size, ensuring comfort and support during exercises requiring hand placement for balance. To ensure the user receives personalized stretching guidance, the microcontroller is connected to an inbuilt database that stores individual user profiles. Based on these profiles, the microcontroller provides customized recommendations for exercises, stretches, and rehabilitation routines, adapting as the user progresses.

[0039] Therefore, the flaps are provided to assist users in maintaining proper posture and balance during different types of stretching exercises. Each handle serves a specific purpose based on the exercise being performed. If a user is performing a standing calf stretch, they might need additional support to maintain stability. The first handle helps the user hold onto a stable surface while positioning their feet on the adjustable foot plates. As the plates adjust to different angles, the handle ensures that the user remains steady and prevents accidental slips.

[0040] For instance, if a user is performing a seated stretch, such as a seated hamstring stretch, they might need to place their hands on a support surface to lean forward safely without straining their back. The second handle allows the user to adjust their position comfortably while maintaining the correct stretching posture. The motorized hinges ensure the handles adjust to the user’s grip size and positioning needs.

[0041] The device is equipped with a thermal camera 121, which monitors the user’s leg for signs of inflammation in real-time. Inside a thermal camera 121, there is a special sensor called a microbolometer. This sensor is made up of tiny pixels that detects infrared radiation, which is the heat energy emitted by objects. When the infrared radiation hits the pixels, it causes a change in electrical resistance. The camera then measures this change in resistance for each pixel and converts it into a temperature value. These temperature values are then used to create an image, where different colors or shades represent different temperatures.

[0042] If inflammation exceeds a predetermined threshold, the microcontroller activates a speaker to alert the user to reduce weight and take a rest. This proactive feature helps prevent injury and ensures that the user stays within safe limits during rehabilitation. The speaker is capable of producing clear and natural sound and is capable of adjusting its volume based on ambient noise levels. The speaker consists of audio information, which is in the form of recorded voice, synthesized voice, or other sounds, generated or stored as digital data. This data is often in the form of an audio file. The digital audio data is sent to a digital-to-analog converter (DAC). The DAC converts the digital data into analog electrical signals. The analog signal is often weak and needs to be amplified. An amplifier boosts the strength to a level so that the speaker drives it effectively. The amplified audio signal is then sent to the speaker. The core of the speaker is an electromagnet attached to a flexible cone. These sound waves travel through the air as pressure waves and are picked by the user’s ear.

[0043] An electronic nozzle 122 is also integrated with a medicinal liquid vessel 123, positioned on the bar 107. Upon detecting inflammation, the microcontroller activates the nozzle 122 to dispense medicinal liquid directly onto the affected area, providing immediate relief and enhancing the rehabilitation process. The electronic nozzle 122 works by utilizing electrical energy to automize the flow solution in a controlled flow pattern by converting the pressure energy of a fluid into kinetic energy, which increases the fluid's velocity. Upon actuation of nozzle 122 by the microcontroller, the electric motor or the pump pressurizes the incoming medicinal liquid, increasing its pressure significantly. High pressure enables the medicinal liquid to be sprayed out with a high force onto the affected area, providing immediate relief and enhancing the rehabilitation process.

[0044] A secondary motorized ball-and-socket joint 120 is integrated between the base 101 and the telescopic rod 102, enabling the rod 102 to be tilted at an optimal angle depending on the type of stretching exercise the user selects, which enhances the stretch experience, positioning the user correctly for different exercises. The motorized ball and socket joint consists of a ball-shaped element that fits into a socket, which provides rotational freedom in various directions. The ball is connected to a motor, typically a servo motor which provides the controlled movement. The rod 102 is attached to the socket of the motorized ball and socket joint. The motor responds by adjusting the ball and socket joint and rotates the ball in the desired direction, and this motion is transferred to the socket that holds the rod. As the ball and socket joint move, it provides the necessary movement to the rod 102, to tilt the rod 102 at an optimal angle depending on the type of stretching exercise the user selects, which enhances the stretch experience, positioning the user correctly for different exercises.

[0045] A battery is associated with the device to supply power to electrically powered components which are employed herein. The battery is comprised of a pair of electrode named as a cathode and an anode. The battery uses a chemical reaction of oxidation/reduction to do work on charge and produce a voltage between their anode and cathode and thus produces electrical energy that is used to do work in the device.

[0046] The present invention works best in the following manner, where the operation of the device begins when the user places their feet inside the wearable body. The wearable body is secured using flaps 117 that are operated through motorized hinge joints. These flaps 117 ensure the firm grip around the user's feet, preventing accidental removal. To further enhance security, electromagnets located on the free ends of the flaps 117 and lateral sides of the wearable body are activated, ensuring the tight fit and preventing unintentional opening while walking. Once the body is securely worn, the artificial intelligence-based imaging unit 104 begins capturing real-time images of the user's surroundings. This imaging unit 104 processes the captured data using artificial intelligence and machine learning techniques to detect obstacles in the user’s path. If the obstacle is identified, the microcontroller processes the data and activates the set of vibrating units that are evenly distributed on the wearable body. These vibrating units provide haptic feedback to guide the user in the safe direction. Additionally, if the approaching vehicle is detected, the holographic projection unit 111 is activated, projecting the 3D visual warning to alert drivers of the presence of the visually impaired individual, thereby improving user safety. To provide protection from animals, the infrared sensor detects their presence and signals the microcontroller to activate the telescopic pusher housed within the hollow cylindrical member. This mechanism releases rubber-pins through the motorized slidable flap to deter the approaching animal in the non-harmful manner. The force of the release is enhanced by the electromagnetic spring integrated within the chamber. The moisture sensor that detects wet surfaces to prevent the user from slipping. If moisture levels exceed the set threshold, the microcontroller activates pneumatic blocks 113 located at the lower portion of the wearable body. These blocks 113 extend to provide additional traction, reducing the risk of slipping and ensuring stability on wet surfaces. For maintaining balance and stability, the wearable body is equipped with the gyroscopic sensor that continuously monitors the user's posture. If the imbalance is detected, the microcontroller adjusts the position of weight blocks 113 inside the wearable body using the two-axis motorized slider 115. To monitor the user’s health, the wearable band is equipped with the Fiber Bragg Grating sensor and the temperature sensor, which continuously track vital parameters such as heart rate, blood pressure, and body temperature. The collected health data is analyzed in real-time, and if any abnormalities are detected, the microcontroller generates the wireless notification that is sent to the linked computing unit, allowing caregivers or family members to take necessary action. In the presence of potholes, the microcontroller activates the embedded speaker that issues audible alerts, prompting the user to take appropriate action, such as jumping over the pothole. The speaker adapts its volume based on surrounding noise levels and customizes its alerts according to the user's past walking behavior through machine learning protocols. Contact sensors further ensure that the device is only activated when the user’s feet are correctly positioned within the wearable body. If the imaging unit 104 detects that the user is unable to navigate safely around the obstacle, the microcontroller provides the alternative route by delivering both audible and visual navigation instructions, allowing the user to find the safer path. To improve the user's comfort, the odor sensor detects foul smells in the surroundings. If the unpleasant odor is detected, the microcontroller activates the electronically controlled nozzle 122 to spray aromatic liquid stored in the vessel 123, ensuring the more pleasant environment.
