[0020] The present invention relates to a hand-held calluses and extra skin removal assistive device for foot that is capable of removing calluses and extra skin from the user's foot portion as per thickness of the calluses and extra skin without causing any injury to the user's foot portion. Additionally, the device is also capable in providing a gentle massaging sensation on the user's foot in order to reduce stress and strain from the user's foot.

[0021] Referring to Figure 1, an isometric view of a hand-held calluses and extra skin removal assistive device for foot is illustrated, comprising an elongated body 101 having a handle 102 arranged with a U-shaped member 103, an artificial intelligence-based imaging unit 104 installed on the body 101, a motorized roller 105 carved with multiple extendable blades 106 attached with the member 103, an electronic nozzle 107 connected with a vessel 108 installed with the body 101, a Peltier unit 109 configured within the body 101, and a push button 110 crafted on the handle 102.

[0022] The proposed device comprises of an elongated body 101 having a handle 102 that is accessed by a user for acquiring a grip over the body 101. Herein, a free end of the body 101 is arranged with a U-shaped member 103 that is poisoned by the user in proximity to foot portion. A push button 110 is crafted on the handle 102 for allowing the user to activate/ de-activate the device. The push button 110 complete the circuit of the device to activate a microcontroller associated with the device for triggering all the components of the device to operate accordingly.

[0023] The body 101 is installed with an artificial intelligence-based imaging unit 104 installed on the body 101 to detect dimensions of the foot portion. The imaging unit 104 comprises of a camera and processor that works in collaboration to detect the dimensions of the foot portion. An AI (artificial intelligence) protocols encrypted with the processor linked with the imagining module to enhance its functionality and capabilities. The AI protocols are used to process and analyses the images captured by the camera enabling it to perform various tasks beyond traditional image capturing. The AI analysis is performed locally on the camera itself and the real-time processing on the camera enables immediate responses and faster decision-making.

[0024] The camera, herein captures images in vicinity of the body 101 with the help of specialized lenses designed to capture high-quality visuals. The captured data is now pre-processed via the processor to enhance its quality and prepare it for AI analysis. This pre-processing involves tasks such as noise reduction, image stabilization, or color correction. The processed data is fed into AI protocols for analysis which utilizes machine learning techniques, such as deep learning neural networks, to extract meaningful information present in the images.

[0025] The camera is capable of analysing the vicinity of the body 101 and providing real-time updates or alerts about the vicinity of the body 101 based on predefined rules or criteria. Herein, based on extraction of the data from the captured images, the microcontroller analyzes the data to detect dimension of the foot portion. Based on detection, the microcontroller actuates a motorized roller 105 carved with multiple extendable blades 106 ranging from 4 to 6 in numbers attached with the member 103 for rotating to peel out extra skin and calluses from the user's foot portion. The roller 105 is coupled with a DC (Direct Current) motor that is activated by the microcontroller to provide circular motion to the roller 105. The working principle of a DC motor is based on the interaction between a magnetic field and an electric current. When an electric current flows through the coil of wire, also known as the armature, it creates a magnetic field. This magnetic field interacts with the fixed magnets, known as the stator, causing the armature to rotate. The rotation is achieved by reversing the direction of the current flow in the armature coil using a commutator and brushes that provide continuous movement of the motor results in providing circular motion to the roller 105.

[0026] Further, the extension and retraction of the blades 106 aid in proper peeling of the extra skins from the foot portion. The blades 106 are equipped with a pneumatic unit that is activated by the microcontroller to provide extension and retraction of the blades 106. The pneumatic unit comprises of an air compressor, air cylinder, air valves and piston. The air valve that allows entry or exit of the compressed air from the compressor. Furthermore, the valve opens and the compressed air enters inside the cylinder thereby increasing the air pressure of the cylinder. The piston is connected to the cylinder and due to the increase in the air pressure, the piston extends due to which the blades 106 extend to aid the roller 105 in peeling of extra skin and calluses from the user's foot portion.

[0027] A touch sensor, herein is installed on the roller 105 to determine contact of the roller 105 with the user's foot portion. The touch sensor comprises a sensing element known as elastomer for sensing the interaction of the foot portion with the user's foot portion. When the sensor is subjected to the interaction, the sensor gets activated and behave like a switch. When the interaction is released, the touch sensor acts as closed switch to experience the force exerted by the by the roller 105. This force leads to deflection in the elastomer which is measured and converted into an electrical signal. After that the touch sensor transmits the electric signal to the microcontroller linked with the sensor. The microcontroller now analyzed the signal to detect the contact of the roller 105 with the user's foot portion.

[0028] Based on detecting the contact of the roller 105 with the user's foot portion, the microcontroller actuates an electronic nozzle 107 connected with a vessel 108 configured on the body 101 for dispensing an optimum amount of moisturizing solution over the user's foot portion. The nozzle 107 herein includes solenoids, piezoelectric actuators, or motor-driven mechanisms that converts electrical signals into mechanical motion. The nozzle 107 is controlled by a control unit that sends electrical signals to the actuation mechanism. The control unit includes a pulse width modulation (PWM) or analog voltage control. The primary function of the nozzle 107 is to control the opening and closing of the nozzle 107's orifice or aperture.

[0029] Upon receiving the appropriate electrical signal by the actuation mechanism, it initiates the motion that opens or closes the nozzle 107. This action controls the flow of the solution through the nozzle 107. The nozzle 107 allows precise control over the flow rate and direction of the solution. By modulating the actuation mechanism according to the desired parameters, the nozzle 107 is capable to regulate the flow and provide accurate dispensing of the moisturizing solution over the user's foot portion in order to apply the moisturizing solution over entire foot portion of the user and loosen the calluses and extra skin.

[0030] Further, an optical sensor is installed on the body 101 and synced with the imaging unit 104 for detecting thickness of the calluses and extra skin. The optical sensor works by emitting light onto the skin surface and measuring the amount of light reflected back. This data is then used to calculate the thickness of calluses and extra skin and send the detected data to the microcontroller for analysing the data to detect the thickness of the calluses and extra skin. Based on detecting thickness of the calluses and extra skin, the microcontroller actuates the blades 106 to extend for facilitating peeling of the calluses and extra skin, and synchronously the microcontroller actuates the DC (Direct Current) motors integrated in between each ends of the roller 105 and the member 103 to rotate with an optimum speed resulting in removal of the calluses and extra skin from the user's foot portion.

[0031] A RPM (revolution per minute) sensor integrated on the roller 105 for detecting rotational speed of the roller 105 during peeling of the calluses and extra skin. The RPM sensor works by detecting the rotational speed of the roller 105 and converting this information into an electrical signal. This signal is then sent to the microcontroller where it analyses the signal to detect the rotational speed of the roller 105 during peeling of the calluses and extra skin. Further, a tactile sensor is installed on the blades 106 to detect hardness of the calluses and extra skin. The tactile sensor comprises a sensing element known as elastomer for sensing the interaction of the skin. When the sensor is subjected to the interaction, the sensor gets activated and behave like a switch.

[0032] When the interaction is released, the tactile sensor acts as closed switch to experience the force exerted by the by the skin over the roller 105. This force leads to deflection in the elastomer which is measured and converted into an electrical signal. After that the tactile sensor transmits the electric signal to the microcontroller linked with the sensor. The microcontroller now analyzes the signal to detect the hardness of the calluses and extra skin. Based on detecting the harness of the calluses and extra skin, the microcontroller determines a rotational speed of roller 105 along with the blades 106, and accordingly the microcontroller regulates actuation of the DC motors for rotating the roller 105 with determined speed.

[0033] Further, a vibrating unit is assembled on the roller 105 for providing a gentle massaging sensation on the user's foot in order to reduce stress and strain from the user's foot. The vibrating unit works by converting electrical energy into mechanical energy which causes the unit to vibrate. The unit comprises of a motor, eccentric weight and shaft, as the microcontroller directs the motor the shaft rotates which in turn rotates the weight. The rotation of weigh creates the unbalanced forces which leads in vibration of the unit resulting in the providing vibrational sensations in the user's foot to reduce stress and strain from the user's foot.

[0034] Moreover, a Peltier unit 109 is configured within the body 101 for providing heat to the user's foot for enhancing blood circulation, in order to aid the skin and surrounding skin more pliable. The Peltier unit 109 comprises of junctions and a thermoelectric generator (TEG) that is a solid unit which converts the heat into electric energy by the phenomena of see beck effect that is also known as form of thermoelectric effect. Further when the current flows through the junctions, the heat is removed from one junction to regulate the temperature within user's foot in view enhancing blood circulation making the skin and surrounding skin more pliable.

[0035] A battery (not shown in figure) is associated with the device to offer power to all electrical and electronic components necessary for their correct operation. The battery is linked to the microcontroller and provides (DC) Direct Current to the microcontroller. And then, based on the order of operations, the microcontroller sends that current to those specific electrical or electronic components so they effectively carry out their appropriate functions.

[0036] The present invention works best in following manner, where the elongated body 101 as disclosed in the invention possesses a handle 102 that is accessed by a user for acquiring a grip over the body 101 having a free end of the body 101 is arranged with a U-shaped member 103 that is poisoned by the user in proximity to foot portion. The artificial intelligence-based imaging unit 104 detects dimensions of the foot portion, based on which the microcontroller actuates a motorized roller 105 carved with multiple extendable blades 106 for facilitating peeling of extra skin and calluses from the user's foot portion. Also, the touch sensor determines contact of the roller 105 with the user's foot portion, and upon successful detection the microcontroller actuates the electronic nozzle 107 for dispensing an optimum amount of moisturizing solution over the user's foot portion in view of applying the moisturizing solution over entire foot portion of the user and loosen the calluses and extra skin. Also, the optical sensor detects thickness of the calluses and extra skin based on which the microcontroller actuates the blades 106 to extend for facilitating peeling of the calluses and extra skin, and synchronously the microcontroller actuates the pair of DC (Direct Current) motors to rotate with an optimum speed, resulting in removal of the calluses and extra skin from the user's foot portion. Herein, the rpm (revolution per minute) sensor detects rotational speed of the roller 105 during peeling of the calluses and extra skin, and the tactile sensor detects hardness of the calluses and extra skin, based on which the microcontroller determines a rotational speed of roller 105 along with the blades 106 , and accordingly the microcontroller regulates actuation of the DC motors for rotating the roller 105 with determined speed. Also, the Peltier unit 109 provides heat to the user's foot in view enhancing blood circulation, making the skin and surrounding skin more pliable.
