[0021] 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.

[0022] The present invention relates to automated sofa repairing device that is capable of repairing sofa in an automated manner by detecting the presence of damaged portion on sofa thereby reducing the physical efforts of the user.

[0023] Referring to Figure 1, an isometric view of an automated sofa repairing device comprising, a platform 1 developed to be positioned on a ground surface within an enclosure and installed with a plate 2, a motorized scissor arrangement 3 configured between platform 1 and plate 2, a robotic arm 4 installed on plate 2 and mapped with an electronic nozzle 5 connected with a multi-sectioned chamber 6, an hot air blower 7 mapped on plate 2.

[0024] The proposed invention comprises of a platform 1 developed to be positioned on a ground surface within an enclosure and installed with a plate 2. The platform 1 is made up of stainless steel that offers a corrosion resistant, strength and durability to the device and is easy to maintain. Further, the microcontroller actuates a touch enabled screen mapped on the platform 1 to allow user to give input commands for maintenance of leather sofa present within enclosure. The touch enabled screen mapped herein consists of multiple tiny electrically active wires. When user touch the options illustrated over the screen, the wires are pressed together and circuit is completed. Which results in flow of voltages across the circuit. That voltage flow is detected by a microcontroller linked with the screen in form of electric signals. Further the signals are processed by the microcontroller thereby allowing user to give input commands for maintenance of leather sofa present within enclosure.

[0025] Thereafter, a microcontroller linked with screen processes input commands and activates a camera mounted on plate 2 for capturing and processing multiple images in vicinity of plate 2 that are processed by microcontroller via an artificial intelligence protocol encrypted within microcontroller and displayed on screen. The camera comprised of a lens and a digital camera sensor, wherein the camera lens takes all the light rays rebounding around the user and utilizes the lenses to transmit them to a single point for creating a sharp image. When all of those light rays rebound back and meet together on a digital camera sensor, create a digital image of the user by performing various operations like pre-processing, feature extraction and classification which is transmitted to the processor. The processor further extracts all the required information from the digital images and transmit to an inbuilt microcontroller associated with the device, which further processes the information shared by the processor in order to determine location where maintenance is to be done. The artificial intelligence protocol encrypted within microcontroller and displayed on screen, wherein user is required to access screen for selecting exact location at which maintenance of leather of sofa is to be done.

[0026] Further, the microcontroller actuates multiple omnidirectional wheels attached underneath platform 1 for maneuvering and positioning platform 1 in proximity to sofa. The omnidirectional wheels have small discs or rollers around the circumference of the wheel, allowing the wheels to move in all directions, which provide the platform 1 with the required movement in proximity to sofa. Herein, the microcontroller actuates an IR (Infrared) sensor mapped on plate 2 to monitor presence of damaged/ torn portion of sofa. The IR (Infrared) sensor comprises of an infrared (IR) emitter and a photodiode. The emitter emits infrared waves of low frequency on the currency which is reflected back to the photodiode. The measured reading is taken into account by the sensor and is send in the form of electrical signal to the sensing module. Thus the microcontroller processes the measured reading received from the sensing module and monitor presence of damaged/ torn portion of sofa.

[0027] Based on the torn portion of sofa, the microcontroller actuates a motorized scissor arrangement 3 attached between platform 1 and plate 2 for lifting and positioning plate 2 at an optimum height to damaged/ torn portion of sofa. The motorized scissor arrangement 3 comprises of a scissor mechanism which is constructed of linked, crisscrossing metal supports that resemble a pair of scissors. When the scissor arm 4 s are extended, the plate 2 is raised and when they retract, the plate 2 is lowered. The scissor mechanism is powered hydraulically in which hydraulic jacks are installed in the mechanism which is linked with a hydraulic unit associated with the arrangement. The hydraulic unit comprises of a hydraulic pump, solenoid valve and hydraulic piston-cylinder. The hydraulic pump used herein extract the hydraulic oil from a reservoir and pressurized the fluid mechanically. The hydraulic pump consists of two main parts including a motor and a propeller. The motor rotates the propeller which uses the energy from the motor drive to draw in hydraulic oil from the reservoir and compress to elevated pressure. The compressed hydraulic oil is then sent through a discharge tube into the cylinder across the solenoid valve. As per the signal from the microcontroller, the solenoid valve opens and allows the entering of the pressurized oil in the cylinder. The solenoid valve comprises of a gate and a magnetic coil, which on energizing generates the magnetic force which tries to push the gate to open and allow the flow of oil in the jack The pressurized oil within the cylinder tend to pushes out the piston out from the cylinder which results in extension hydraulic jacks for raising the plate 2 to at an optimum height to damaged/ torn portion of sofa.

[0028] Herein, the microcontroller actuates an optical sensor mapped on plate 2 and synced with imaging unit to detect presence of cracks on leather of sofa along with color of leather. The optical sensor works by using light to detect the presence of the cracks on leather of the sofa along with color of leather. The optical sensor contains a light emitter and a light detector. On actuation the emitter emits a beam of light which travels through the air until it hits the sofa. If there is a leak or hole in the pipe, then the light beam will be refracted, which causes the intensity of the light to decrease. The light detector then detects the decrease in light intensity and sends a signal to the microcontroller. The microcontroller, after processing the signal, detect the presence of cracks on leather of sofa along with color of leather.

[0029] Depending on the cracks, the microcontroller actuates a robotic arm 4 mapped on plate 2 and installed with an electronic nozzle 5 connected with a multi-sectioned chamber 6 stored with multiple leather color paint. The robotic arm 4 is a type of mechanical arm 4 which is usually available with similar function to a human arm 4 . The segments of such a manipulator are connected by joints allowing either rotational motion or translational displacement. The robotic arm 4 contains several segments that are attached together by joints also referred to as axes. The robotic arm 4 contains several segments that are attached together by motorized joints also referred to as axes. Each joints of the segments contains a step motor that rotates and allows the robotic arm 4 to complete a specific motion in translating the equipped roller over the foil for placing nozzle 5 in proximity to damaged/ torn portion of sofa.

[0030] Simultaneously, the microcontroller actuates the nozzle 5 to dispense a particular paint solution in damaged/ torn portion for repainting crack. The nozzle 5 comprises of a gate and a magnetic coil which uses electricity from microcontroller to generate the force to control the opening/closing of gate to control the flow of a cleaning solution through a small aperture of the nozzle 5, allowing for precise control of the flow of the paint solution thereby dispensing a particular paint solution in damaged/ torn portion for repainting crack.

[0031] Herein, a flap is attached with multiple rectangular-shaped members interconnected by means of multiple hinges and positioned on the body via an extendable L-shaped link that is actuated by microcontroller to extend for positioning flap in proximity to detected crack. The extendable L-shaped link is powered by a pneumatic unit consist of an air compressor, air valves, a piston. The air compressor used herein extract the air from surrounding and increases the pressure of the air by reducing the volume of the air. The air compressor consists of two main parts including a motor and a pump. The motor powers the compressor pump which uses the energy from the motor drive to draw in atmospheric air and compress to elevated pressure. The compressed air is then sent through a discharge tube into the cylinder across the valve. The compressed air in the cylinder tends to pushes out the piston to extend which extends for positioning flap in proximity to detected crack.

[0032] Further, the microcontroller actuates hinges to tilt member to acquire shape of contours of seat in order to flatten and smoothen crack for repairing crack. The hinge are mechanical bearings that are used to connect two swinging objects or points to one another and give them the freedom to move relative to each other. Hinges have limited movement, allowing the joint to move only at one angle and restrict the other movements of swinging parts thereby tilting member to acquire shape of contours of seat to flatten and smoothen crack for repairing crack.

[0033] Thereafter, the microcontroller actuates a hot air blower 7 installed on plate 2 to blow hot air over applied color paint. The comprises of a heater, vortex, impeller and an outlet duct. The blower 7 increase the pressure of the absorbed air by a series of vortex motions formed by the centrifugal movement of the impeller. When the impeller is rotating, the channels in the impeller push the absorbed air forward through a heater, that increase the temperature of the absorbed air by creating the centrifugal movement that generates a helical movement of the air. During this centrifugal movement, the absorbed air is continuously compressed along the channel and the pressure increases linearly. The pressurized air is transferred from the outlet duct of the blower 7 to blow hot air over applied color paint.

[0034] Herein, a telescopically operated L-shaped rod is positioned on plate 2 and attached with a motorized rotatable brush that is actuated by microcontroller in sync with imaging unit to perform scrubbing on damaged portion in to enhance texture of sofa. The telescopically operated L-shaped rod is powered by a pneumatic unit which aids in positioning of the motorized rotatable brush in proximity to sofa. The motorized rotatable brush comprises of multiple bristles and coupled to a DC motor performs scrubbing on the damaged portion to enhance texture of the sofa.

[0035] Herein, the microcontroller actuates a level sensor is positioned within each of chamber 6 for detecting level of color paint stored within chamber 6. The level sensor consists of a measuring cell which detects the pressure on the measuring cell of the sensor when put into certain depth in the color paint stored within chamber 6. Further the detected pressure is converted into electrical pulse and transmitted to the microcontroller. The microcontroller evaluates the level of color paint by analyzing the detected pressure value, pre-set density and gravity value.

[0036] In case the detected water level recedes a threshold level, microcontroller sends an alert on a computing unit associated with device for notifying user to re-fill container. The computing unit is wirelessly linked with a microcontroller via a communication module which includes but not limited to Wi-Fi (Wireless Fidelity) module, Bluetooth module, GSM (Global System for Mobile Communication) module. The communication module employed herein acts as an intermediate between various electronic components, wherein it is used to establish the communication between the users computing unit and the microcontroller.

[0037] 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.
