[0019] 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.

[0020] The present invention relates to a fabric dyeing device that requires to be capable of dyeing fabrics in different colors with pigments and water as per a specific ratio for the colour selected by the user. Additionally, the proposed device needs to maintain toning of the fabrics appropriately without any chances of fading of the fabrics.

[0021] Referring to Figure 1, an isometric view of a fabric dyeing device is illustrated, comprising a cuboidal housing 101 having four perpendicularly installed telescopic rods 102 having suction units 103 at the ends, attached underneath the housing 101, a circular opening 104 provided on the housing 101, a pair of telescopic grippers 105 attached inside the housing 101 by means of ball and socket joints 106, a motorized primary roller 107 disposed within the housing 101 by means of L-shaped telescopic bars 108, a touch enabled display unit 109 provided on the housing 101, an artificial intelligence-based imaging unit 110 installed in the housing 101, a speaker 111 provided on the housing 101, multiple chambers 112 configured with nozzles 113 disposed within the housing 101, a Peltier unit 114 integrated in the housing 101, multiple stirring rods 115 provided in the housing 101, multiple robotic arms 116 attached within the housing 101, a string 117 dispensed from a secondary roller 118 provided with the housing 101, and multiple iris holes 119 provided underneath the housing 101.

[0022] The proposed device comprises of a cuboidal housing 101 made up of any material, designed for efficient dyeing of fabric. The housing 101 is encased with various components associated with the device arrange in sequential manner that aids in dyeing the fabrics. Upon placing of the housing 101 over placed over a surface around an area, four perpendicularly installed telescopic rods 102 with suction units 103 at the ends, attached underneath the housing 101 provides stability to the housing 101. The suction units 103 create partial vacuum within the suction units 103 upon pressing over the surface by squeezing out air from the suction units 103 due to a negative pressure is generated inside suction area. Herein, atmospheric pressure outside the suction units 103 presses down low-pressure area inside the suction units 103 to generate suction to adhere the surface and affix the housing 101 with the surface thereby accommodating the housing 101 over the surface in an appropriate manner.

[0023] After the securing of the housing 101 over the surface, the user accesses a circular opening 104 provided on the housing 101 for inserting a fabric into the housing 101 for dyeing. After that the user requires to activate the device manually by pressing a switch button associated with the device and integrated with the housing 101. The button is a type of a switch that is internally connected with the device via multiple circuits that upon pressing by the user, the circuits get closed and starts conducting electricity that tends to activate the device and vice versa. After activation of the device by the user, a microcontroller associated with the device generates commands to operate the device accordingly.

[0024] After activating of the device, the microcontroller actuates an artificial intelligence-based imaging unit 110 for detecting presence of the fabric in the housing 101 and type of fabric. The imaging unit 110, mentioned herein comprises of comprises of a camera and processor that works in collaboration to capture and process the images of surrounding of the housing 101. The camera firstly captures multiple images of the surrounding, wherein the camera comprises of a housing 101, electronic shutter, lens, lens aperture, image sensor, and imaging processor that works in sequential manner to capture images of the surrounding. After capturing of the images by the camera, the shutter is automatically open due to which the reflected beam of light coming from the surrounding due to light is directed towards the lens aperture. After that the reflected light beam passes through the image sensor.

[0025] The image sensor now analyzes the beam to retrieve signal from the beams which is further calibrate by the sensor to capture images of the surrounding in electronic signal. Upon capturing images, the imaging processor processes the electronic signal into digital image. When the image capturing is done, the processor associated with the imaging unit 110 processes the captured images by using a protocol of artificial intelligence to retrieve data from the captured image in the form of digital signal. The detected data in the form of digital signal is now transmitted to the linked microcontroller based on which the microcontroller acquires the data to detect the presence of the fabric in the body and type of fabric.

[0026] Based on detecting the presence of the fabric and type of fabric, the microcontroller actuates a pair of telescopic grippers 105 assembled inside the housing 101 by means of ball and socket joints 106 for gripping the fabric and aligning on a motorized primary roller 107 integrated within the housing 101 by means of L-shaped telescopic bars 108. The gripers are equipped with a pneumatic unit that is activated by the microcontroller to provide extension and retraction of the grippers 105 to grip the fabric. The pneumatic unit comprises of an air compressor, air cylinder, air valves i.e. Inlet and outlet valve and piston that works in collaboration to aid extension and retraction of the grippers 105. The air compressor is coupled with a motor that gets activated by the microcontroller to compress the air from surroundings upon entering from the inlet valve to compressed and pumped out via the outlet valve. The air valve 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.

[0027] The piston is connected to the cylinder and due to the increase in the air pressure, the piston extends. And upon closing of the valve, the compressed air exit out from the cylinder thereby decreasing the air pressure of the cylinder. The increasing and decreasing of the air pressure from the cylinder aids in extension and retraction of the piston that turns in aiding extension and retraction grippers 105 to grip the fabric. Herein, the ball and socket joint assist the grippes to place the fabric on the motorized primary roller 107. The ball and socket joint 106 a mechanical arrangement consists of a ball-shaped component that fits into a socket, with the motor and controller actuated by the microcontroller providing the necessary power to drive the rotation to provide angular movement to the grippers 105 to place the fabric on the primary roller 107.

[0028] Before dying the fabric, a dust sensor provided in the housing 101 detects dust in the fabric. The dust sensor works by utilizing optical or laser-based technology to detect particles. The dust sensor emits a beam of light onto the fabric surface, and the scattered or reflected light caused by dust particles is analyzed to determine the presence and concentration of the dust. Based on detecting the dust, the microcontroller actuates a vibration unit embedded in the primary roller 107 to vibrate the fabric to dislodge the dust. The vibration 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 primary roller 107 to dislodge the dust from the fabric.

[0029] A proximity sensor mentioned herein installed on the housing 101 detects a presence of the user near the. The proximity sensor operates by emitting electromagnetic signals or utilizing capacitive, infrared, or ultrasonic technologies to sense changes in the surrounding caused by the user's approach. When the user enters the sensor's detection range, the reflected or interrupted signals are analyzed, triggering the sensor to detect the user's presence. Based on detecting the microcontroller actuates a touch enabled display unit 109 provided on the housing 101 to display various colour options for dyeing of fabric.

[0030] The display unit 109 works by using LCD (liquid crystal Display) that are manipulated by electric currents to control the passage of light through the display unit 109. When an electric current is applied, the liquid crystals align in a way that either allows light to pass through or blocks the light, creating the images and colors that is being visible in the LCD of the display unit 109 regarding various colour options for dyeing of fabric that is further change the electric charge at the location of the touch to register as input. The user input is then sent to the liked microcontroller to process the input.

[0031] Upon the color selection given by the user, the microcontroller matches the color’s input compatible with the fabric. Based on matching, if the detect fabric type is incompatible with the colour chosen by the user, then the microcontroller activates a speaker 111 provided on the housing 101, to notify the user regarding selected colour being incompatible for the fabric. The speaker 111 includes a diaphragm, which is typically made of a lightweight and rigid material like paper, plastic, or metal to vibrate and produce sound waves when electrical signals are fed to it for notifying the user. After passing of the electrical signal through a voice coil suspended within a magnetic gap of the speaker 111, it generates a magnetic field that interacts with the fixed magnetic field produced by a magnet assembly associated with the voice coil.

[0032] Upon variation in electrical current, the magnetic field produced by the voice coil changes, resulting in the voice coil and attached cone/diaphragm moving back and forth. This movement creates pressure variations in the surrounding air, generating sound waves to generate the audible sound to notify the user integrated on the housing 101 to notify the user regarding selected colour being incompatible for the fabric and allow the user to re-select the color compatible for the fabric. After that the microcontroller actuates multiple nozzles 113 integrated with multiple chambers 112 disposed within the housing 101 for dispensing water and pigments as per a specific ratio in accordance with colour selected by the user to dye the fabric. The nozzle 113 includes solenoids, piezoelectric actuators, or motor-driven mechanisms that converts electrical signals into mechanical motion. A control unit that sends electrical signals to the actuation mechanism controls the nozzle 113.

[0033] The control unit includes a pulse width modulation (PWM) or analog voltage control. The primary function of the nozzle 113 is to control the opening and closing of the nozzle’s orifice or aperture. Upon receiving the appropriate electrical signal by the actuation mechanism, it initiates the motion that opens or closes the nozzle 113. This action controls the flow of water and pigments through the nozzle 113. The nozzle 113 allows precise control over the flow rate and direction of the water and pigments. By modulating the actuation mechanism according to the desired parameters, the nozzle 113 is capable to regulate the flow and provide accurate dispensing of the water and pigments on the fabric. Herein, the nozzles 113 are configured with flowmeters to maintain accurate dispensing of the pigments in the housing 101 for accurate colour mixing.

[0034] The flowmeter operates by measuring the flow rate of the pigment as it passes through the nozzle 113. This is achieved using technologies such as turbine sensors, ultrasonic waves, electromagnetic fields, or positive displacement mechanisms. The flowmeter continuously monitors and adjusts the flow to ensure consistency and accuracy, preventing over- or under-dispensing to achieve the desired color precision in the mixing. After that the microcontroller actuates multiple stirring rods 115 provided in the housing 101 for stirring the mixture. The stirring rods 115 are equipped with a motor that is activated by the microcontroller to rotate the stirring rods 115 with specified speed to mix the mixture during heating of the mixture in order to bond the color on the fabric.

[0035] After the dispensing of the mixture over the fabric, a Peltier unit 114 integrated in the housing 101 heats mixture of the pigments for bonding of the colour with the fabric. The Peltier unit 114 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 produce heating effect in the housing 101 to heat the mixture for bonding the color on the fabric.

[0036] A temperature sensor mentioned herein integrated in the housing 101 detects temperature of the mixture. The temperature sensor operates based on the principle of detecting infrared radiation emitted by the mixture. The contactless temperature sensor comprises crucial components such as an infrared sensor, an optical arrangement, and a detector. It functions on the principle of detecting infrared radiation emitted by the mixture. When the mixture’s temperature exceeds absolute zero, it emits infrared radiation. The sensor captures this radiation using its optical arrangement, directing it onto a detector. Common detectors, like thermopiles or pyroelectric sensors, then convert the received infrared energy into an electrical signal. This signal undergoes processing by electronic components, translating it into a temperature reading of the mixture. Based on detecting the temperature of the mixture, the microcontroller regulates actuation of the Peltier unit 114 as per fabric type to bond the color on the fabric.

[0037] Additionally, the user accesses the displays unit to create patterns on the fabric while dyeing based on that the microcontroller actuates multiple robotic arms 116 attached within the housing 101 for tying the fabric with a string 117 dispensed from a secondary roller 118 provided with the housing 101. The robotic arm 116 comprises of a shoulder, elbow and wrist. All these parts are configured with the microcontroller. The elbow is at the middle section of the arm 116 that allows the upper part of the arm 116 to move the lower section independently. Lastly, the wrist is at the tip of the upper arm 116 and attached to the end effector works as hand for gripping the string 117 to tie over the fabric to create patterns on the fabric while dyeing. After dyeing, multiple iris holes 119 provided underneath the housing 101 drain out the mixture.

[0038] 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 the user effectively carry out their appropriate functions.

[0039] The present invention works best in the following manner, where the cuboidal housing 101 as disclosed in the invention possesses four perpendicularly installed telescopic rods 102 with suction units 103 at the ends for a stabilisation of the base. Herein, the circular opening 104 is accessed by the user for inserting a fabric into the housing 101 for dyeing. Herein, the artificial intelligence-based imaging unit 110, detects presence and type of fabric to trigger the microcontroller to actuate the pair of telescopic grippers 105 by means of ball and socket joints 106, for gripping the fabric and aligning onto the motorized primary roller 107 by means of L-shaped telescopic bars 108. Herein, the proximity sensor to detect a presence of the user near the housing 101 and based on that, the microcontroller actuates the touch enabled display unit 109 to display various colour options for dyeing of fabric. Based on selection, the speaker 111 generates an audio alert for the user regarding selected colour being incompatible for the fabric if the detect fabric type is incompatible with the colour chosen by the user. After that the nozzles 113 are actuated to dispense water and pigments into the housing 101 as per a specific ratio in accordance with colour selected by the user to dye the fabric. Herein, the Peltier unit 114 heats mixture of the pigments for bonding of the colour with the fabric, and the stirring rods 115 for stirring the mixture. Further to create patterns on the fabric while dyeing, the user accesses the display unit 109 to give input regarding the same, based on that the robotic arms 116 tie the fabric with a string 117 dispensed from the secondary roller 118 to create patterns on the fabric while dyeing.
