Description:FIELD OF THE INVENTION

[0001] The present invention relates to a kneeling tasks mobility assistive device that is capable of ensuring a precise and adaptable fit for various knee sizes, providing optimal support and comfort, evenly distributing pressure and reducing discomfort or irritation, making it suitable for prolonged use, enabling hands-free control and ease of operation.

BACKGROUND OF THE INVENTION

[0002] Individuals with knee mobility challenges often face significant difficulties that affect their daily activities and overall quality of life. Pain, stiffness, and limited range of motion in the knee joint make it challenging to perform basic tasks like walking, climbing stairs, or standing for extended periods. Uneven surfaces or obstacles further exacerbate these issues, increasing the risk of falls or injuries. Prolonged discomfort during movement leads to fatigue and reduced confidence, discouraging individuals from staying active. Environmental factors, such as crowded spaces or slippery floors, add another layer of complexity. Without proper assistance or adaptive devices, individuals experience strain on other joints, worsening their condition over time and limiting their independence in both personal and professional environments.

[0003] Traditionally, knee support and mobility devices are standalone aids like braces, walkers, or wheelchairs. These devices are typically manual, offering fixed support and limited adaptability. For example, knee braces provide compression and stability but lack features for active movement assistance. Similarly, wheelchairs and walkers assist with mobility but are not specifically designed for users with knee-related issues, and they require manual operation or external support. Hospitals often rely on separate systems for mobility and healthcare management, which leads to inefficiencies and increased discomfort for users requiring specialized assistance.

[0004] US5038763A This invention relates to a knee support device which enables a knee brace to track closely the movement of the tibia. In use, a complete knee brace comprises two of the knee support devices of this invention, one on each side of the leg. The knee support device comprises an upper and a lower elongated brace member releasably secured to a person's thigh and leg, respectively. Each of the two brace members includes pivot means and gear means, such that the gear means of the two brace members engage each other to rotate each brace member about the pivot means of the corresponding member. The upper and lower brace members on each side of the leg are connected by a link member connecting the pivot means of the two braces. The means for securing the brace members to the leg are placed such that the pivots are anterior to the knee joint, so that the rotation of the lower brace member tracks the tibia in flexion when the person and the brace members are viewed in profile. The link member and portions of the brace members remain close to the knee joint when it is bent to provide greater support and protection for the joint.

[0005] US3677265A A knee support adapted to strengthen and protect injured knees. The support is particularly adapted for use by athletes. The support includes an elastic sleeve and an elastic covering which aid in strengthening the knee by retaining all of the tendons, ligaments, cartilage and muscles firmly in place. Coiled tubes of rubber are positioned between the elastic sleeve and the elastic casing, and are positioned above, below and on the sides of the kneecap when the device is worn. The coiled rubber tubes absorb any shock that may be inflicted on the knee, thereby protecting the injured knee.

[0006] Conventionally, many devices such as standard knee braces, crutches, and mobility aids are employed to assist individuals with knee-related issues. While these devices serve basic functions, they lack features like real-time adjustments, users face challenges such as discomfort during prolonged use, difficulty navigating obstacles, and limited customization to fit individual needs.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a device that offer real-time adjustments to accommodate different user needs, prevent discomfort during long-term use, and navigate environmental challenges effectively. Moreover, provide enhanced protection, ease of movement, and convenience, making it a reliable solution for patients with knee-related issues aiming to deliver superior care.

DETAILED DESCRIPTION OF THE INVENTION

[0018] The following description includes the preferred best mode of one embodiment of the present invention. It will be clear from this description of the invention that the invention is not limited to these illustrated embodiments but that the invention also includes a variety of modifications and embodiments thereto. Therefore, the present description should be seen as illustrative and not limiting.

[0019] In any embodiment described herein, the open-ended terms "comprising," "comprises,” and the like (which are synonymous with "including," "having” and "characterized by") may be replaced by the respective partially closed phrases "consisting essentially of," consists essentially of," and the like or the respective closed phrases "consisting of," "consists of, the like.

[0020] As used herein, the singular forms “a,” “an,” and “the” designate both the singular and the plural, unless expressly stated to designate the singular only.

[0021] The present invention relates to a kneeling tasks mobility assistive device that is capable of providing support, mobility, and comfort to users with knee-related issues or those requiring assistance with movement, securely fit around the knee and adapt to the user’s dimensions, offering customized support.

[0022] Referring to Figure 1, an isometric view of a kneeling tasks mobility assistive device comprises of a hemispherical expandable frame 101 attached with a pair of expandable straps 102, a microphone 103 integrated in the frame 101, plurality of motorized omnidirectional wheels 104 arranged on a front portion of the frame 101, a Peltier unit 105 installed on the frame 101, a shock absorber spring 106 installed in between the wheels 104 and frame 101 and a speaker 107 integrated into the frame 101.

[0023] The device disclosed herein comprises of a hemispherical expandable frame 101 attached with a pair of expandable straps 102, tailored to fit securely around the knee, ensuring optimal comfort and adaptability for various users. The expandable frame 101 contours to the knee's shape, providing stable support, while the expandable straps 102 allow for precise fitting and secure attachment.

[0024] A memory foam layering is provided on inner surface of the frame 101 for providing a comfortable experience to the user. The memory foam developed to enhance user comfort. This soft, adaptive material conforms to the unique contours of the knee, distributing pressure evenly and reducing the risk of discomfort or irritation during use.

[0025] The user presses a button integrated with the frame 101 to activate the device. The button is internally connected with the device via multiple circuits that upon pressing by the user, the circuits get closed and starts conducting electricity through a microcontroller associated with the device that tends to activate the device and vice versa. The device once gets activated, the microcontroller actuates an ultrasonic sensor is embedded in the frame 101 for determining dimensions of the user’s knee portion.

[0026] The ultrasonic sensor operates by emitting high-frequency sound waves beyond the range of human hearing to determine the dimensions of the user’s knee portion, works based on the principle of echolocation, where the sensor transmits ultrasonic pulses that travel through the air and reflect off the knee surface. Upon reflection, the waves return to the sensor, which calculates the time taken for the echo to return. By using the speed of sound in air, the sensor accurately determines the distance between the sensor and the knee.

[0027] Based on the user’s knee portion dimensions, the microcontroller actuates a straps 102 for clasping onto the user’s knee portion, wherein the frame 101 is actuated to adjust as per a user’s knee dimensions, in view of properly securing the frame 101 onto the user’s knee portion.

[0028] Based on the user’s knee dimensions, the frame 101 is incorporated with multiple sliding sections, sliders and a pneumatic locking unit that words in conjunction to expand the frame 101. The multiple sliding section allowing the frame 101 to expand or contract smoothly ensuring a precise fit around the knee. These section provide flexibility and adaptability, accommodating a wide range of knee sizes.

[0029] The pneumatic locking unit operates by utilizing compressed air to create a secure and adjustable locking arrangement, ensuring stability and controlled movement of connected components, consists of a pneumatic cylinder, air valves, and a control system that regulates airflow to engage or disengage the lock. When activated, compressed air is directed into the cylinder, causing an internal piston to move and either extend or retract a locking pin, securely holds the sliding sections or adjustable components in place, preventing unintended movement. The pneumatic locking unit provides precise control over locking and unlocking. When activated the unit directs air into the chamber, creating pressure that engages the locking arrangement to hold the sliders firmly at the position.

[0030] The microcontroller activates a microphone 103 integrated in the frame 101 for enabling the user to provide input voice commands regarding requirement of movement in a desired direction during a kneeling task. When the user speaks to give voice commands to a microphone 103, it first captures the sound waves from the voice. These sound waves hit the diaphragm which vibrates back and forth in response to sound waves. This movement is then transferred to a capacitor connected to the microphone 103 that converts the vibrations into an electrical signal that mirrors the pattern of the sound waves. This signal is sent to the microcontroller which further activates the commands regarding requirement of movement in a desired direction.

[0031] The microcontroller actuates plurality of motorized omnidirectional wheels 104 arranged on a front portion of the frame 101 for providing mobility to the frame 101 over a ground surface, to allow the user for performing the tasks. The motorized wheel operates by integrating an electric motor with a wheel to provide motion. When the motor receives electrical power from a power source which is converted into mechanical energy by the motor, which generates rotational force. When the motor is activated, the motor's shaft starts to rotate, causing the wheel to spin.

[0032] The device features a Peltier unit 105 coupled with a temperature sensor, installed on the frame 101 for detecting temperature of surroundings. The temperature sensor works by detecting changes in thermal energy and converting these variations into electrical signals. These signals are processed to determine the ambient temperature with precision.

[0033] The microcontroller activates the Peltier unit 105 to provide an optimum heating and cooling effect onto the layering for providing an ambient temperature for the user. The Peltier unit 105 works on the Peltier effect where a temperature difference is created by transferring heat between two electrical junctions. A voltage applied across two conductors joined together creates an electrical current. When an electric current is passed, electrons move from a high-energy state to a lower-energy state and release energy in the form of heat. At one junction, the movement of electrons absorbs heat from the surroundings making that side cold while other side where the movement of electrons releases energy, it becomes hot.

[0034] An impact sensor embedded in the frame 101 for detecting any sudden force applied onto the frame 101 during the movement. The impact sensor works by measuring changes in acceleration or pressure on the frame 101, which are translated into electrical signals. When a significant force is detected, the sensor triggers a response, such as alerting the system or initiating protective measures.

[0035] Based on the force applied, the microcontroller activates a shock absorber spring 106 installed in between the wheels 104 and frame 101, thus minimizing impact of the shocks to the user’s knee portion. The shock absorber spring 106 operates by compressing when subjected to an impact, absorbing the kinetic energy, and then gradually releasing it as the spring 106 returns to its original position. This arrangement minimizes the transfer of shocks to the user’s knee, providing smoother movement and enhanced protection against sudden impacts, thereby improving overall comfort and safety during use.

[0036] The device also includes a weight sensor is embedded in the frame 101 for detecting weight of the user, based on which the microcontroller regulates actuation of the spring 106. The weight sensor comprises of a transducer and a strain gauge. The force applied on the sensor due to weight load leads to the deformation of the strain gauge. The deformations are measured and the transducer converts the force to the electrical resistance which is sent as an electrical output to the microcontroller. The sensor detects the weight and as the weight recedes a pre-defined threshold limit, the signal is sent to the microcontroller. The microcontroller sends an alert to the computing unit to notify the user to actuate the springs 106. The computing unit transmits the user’s commands to the device through wireless communication technology such as Wi-Fi or Bluetooth. Upon receiving the commands, the springs 106 are actuated.

[0037] Upon actuating the springs 106, an infrared sensor is embedded in the frame 101 for detecting obstacles to detect obstacles. The infrared sensor works by by emitting infrared light waves and analyzing their reflection. The sensor projects these waves toward the surrounding area, and when they encounter an obstacle, the waves reflect back to the sensor. By measuring the time taken for the waves to return and the intensity of the reflection, the sensor determines the presence and distance of obstacles. Based on the obstacles the frame 101 provides real-time feedback to the user via the small digital screen integrated into the knee pad frame 101, displaying alerts for potential obstructions or hazards.

[0038] The device features a speaker 107 integrated into the frame 101 for emitting auditory signals to provide warnings about detected obstacles or environmental conditions, improving user awareness and safety. The speaker 107 works by converting the electrical signal into the audio signal. It consists of a cone known as a diaphragm attached to a coil-shaped wire placed between two magnets. When the electric signal is passed through the voice coil, it generates a varying magnetic field that interacts with the magnet causing the diaphragm to move back and forth. This movement pushes and pulls air creating sound waves just like the electrical signal received and used to notify the user about detected obstacles or environmental conditions, improving user awareness and safety.

[0039] Moreover, 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 electrodes known as a cathode and an anode. A voltage is generated between the anode and cathode via oxidation/reduction and thus produces the electrical energy to provide to the device.

[0040] The proposed device works in the best manner where the hemispherical expandable frame 101 attached to adjustable straps 102, allowing it to securely fit around the knee. The frame 101 incorporates multiple sliding sections, sliders, and the pneumatic locking unit to expand and contract based on the user’s knee dimensions, ensuring the precise and adaptable fit. The inner surface is lined with memory foam to provide comfort by conforming to the knee’s shape and evenly distributing pressure. Upon activation by the button, the microcontroller triggers an ultrasonic sensor to measure the knee’s dimensions using sound waves. Based on this data, the microcontroller adjusts the frame 101's straps 102 and size to secure the knee properly. The device also includes motorized omnidirectional wheels 104 that provide mobility, powered by electric motors that convert electrical energy into rotational force. The device is further equipped with the microphone 103 that enables users to give voice commands to control movement, enhancing ease of use. Additionally, an infrared sensor detects obstacles by emitting infrared light waves and analyzing their reflection, alerting the user to potential hazards via the digital display and auditory signals from the speaker 107. The Peltier unit 105 and temperature sensor maintain an optimal temperature for the user’s comfort, while an impact sensor detects sudden forces, activating the shock absorber spring 106 to minimize impact on the knee. The device also includes the weight sensor to monitor the user's weight, adjusting the actuation of the spring 106 accordingly.
