BACKGROUND OF THE INVENTION

[0002] Acoustic walls are critical components in many facilities, including industrial plants, offices, theatres, and residential buildings, where noise control is essential to maintain a comfortable and productive environment. Over time, these walls may suffer from structural defects such as cracks, gaps, or wear, which can lead to increased noise transmission and reduced acoustic performance. Maintaining the integrity of these walls and ensuring effective noise absorption is essential for preserving optimal sound quality and comfort within a space. Traditional methods of repairing acoustic walls often involve manual inspection and labour-intensive processes, including identifying defects, applying insulation materials like glass wool, and installing acoustic sheets to seal defects. These methods are not only time-consuming but also prone to inaccuracies, inefficiencies, and human error.

[0003] To address these challenges, automated methods have been proposed that improve the speed, accuracy, and efficiency of acoustic wall maintenance. These methods rely on advanced technologies, such as imaging units, robotic arms, proximity sensors, noise sensors, and motorized tools, to identify defects, dispense insulation materials, and install acoustic sheets with precision. However, existing solutions may still lack comprehensive integration of various functions or are limited in their ability to provide real-time feedback and customization based on the specific needs of a facility.

By adjusting the elasticity of the connecting means, the frequency of each acoustic panel can be individually tuned to treat the various sound frequency ranges. In addition, the device according to the invention enables the acoustic panels to be disconnected from the wall on which they are mounted, thus increasing the insulation of the room.

[0006] Conventionally, many devices are disclosed in prior art that provides a way to maintain acoustic wall often relying on manual inspection and intervention for detecting defects and applying insulation materials. These devices typically involve labour-intensive processes where users must physically identify cracks, gaps, or other structural issues, and then manually install materials like glass wool or acoustic sheets to restore sound absorption.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a device that is capable of marinating acoustic wall by automating the detection of structural defects, dispensing and installing sound-absorbing materials, and securely placing acoustic sheets to improve efficiency, accuracy, and consistency in acoustic wall to restore sound absorption.

[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 an acoustic wall maintenance device that is capable of automatically identify and repair defects in acoustic walls, such as cracks and gaps and applies noise-absorbing materials and soundproofing sheets to enhance the overall acoustic quality and control vibrations in the wall.

[0022] Referring to Figure 1, an isometric view of an acoustic wall maintenance device is illustrated, comprising a base 101 having four sets of tri-wheel assemblies 102 mounted underneath the base 101, a rectangular platform 103 installed on the base 101 by means of a scissor lift 104, an artificial intelligence-based imaging unit 105 installed on the platform 103, an insulation unit 106 disposed on the platform 103, comprising an inverted U-shaped telescopic frame 107 attached on the platform 103, having a motorized primary roller 108 containing a spool of glass wool 109, an articulated L-shaped telescopic bar 110 mounted on the platform 103, having an articulated extendable plate 111, an articulated L-shaped pole 113 having a cutter 114 at an end, provided on the platform 103, a laser Doppler vibrometer 115 provided at an end of an articulated L-shaped telescopic link 116 mounted on the platform 103, a sectioned chamber 117 provided on the platform 103, a pair of robotic arms 118 provided on the platform 103, a laser cutter 119 mounted on a sliding unit 120 installed on an inverted U-shaped structure 121 in front of the chamber 117, a fastener receptacle 122 provided on the platform 103, a magnetic articulated L-shaped gripper 123 provided on the platform 103, an articulated L-shaped limb 124 located on the platform 103, having a power ratchet 125, a touch enabled display unit 126 attached on the base 101, and an articulated L-shaped member 127 having a motorised brush 112 at an end.

[0023] The proposed device comprises of a base 101 encased with various components associated with the device arranged in sequential manner that aids in maintaining acoustic wall. Herein, the base 101 is accessed by a user to position on a fixed surface. Upon placing the base 101 over the fixed surface, the user activates the device manually by pressing a switch button associated with the device and integrated with the base 101. The button mentioned herein 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] Once the device gets activated, the microcontroller activates an artificial intelligence-based imaging unit 105 installed on the platform 103 to detect an acoustic wall including gaps, cracks present in acoustic walls. The imaging unit 105 mentioned herein comprises of comprises of a camera and processor that works in collaboration to detect structural defects in an acoustic wall including gaps, cracks present in acoustic walls. The camera firstly captures multiple images of the surrounding of the base 101, wherein the camera comprises of a body, electronic shutter, lens, lens aperture, image sensor, and imaging processor that works in sequential manner to capture images of the surrounding.

[0025] Firstly, the shutter automatically opens due to which the reflected beam of light coming from the surrounding is directed towards the lens aperture. After that the reflected light beam passes through the image sensor. 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 processor processes the electronic signal into digital image. When the image capturing is done, the processor associated with the imaging unit 105 processes the captured images by using a protocol of artificial intelligence to retrieve data from the captured image in the form of digital signal.

[0026] 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 acoustic wall including gaps, cracks present in acoustic walls. Simultaneously, the microcontroller actuates GPS (global positioning system) provided on the base 101 for detecting the location of the wall. The GPS module works by receiving signals from multiple satellites in orbit to calculate the precise geographic location of the wall. The GPS module determines the position by measuring the time it takes for the satellite signals to reach the receiver, using this data to compute the latitude, longitude, and altitude of the wall's location. By combining signals from at least four satellites, the GPS module achieves accurate positioning. This location data is transmitted to the microcontroller, allowing it to save the location for records.

[0027] Based on the location and structural defects detected in the wall, the microcontroller actuates multiple noise sensors embedded in the platform 103 to detect regions of the wall with detected defects. The noise sensor mentioned herein works by detecting sound frequencies generated by potential defects or irregularities in the wall structure. After that the noise sensor identifies changes in sound patterns that indicate areas of weakness or issues in the wall.

[0028] After indicating areas of weakness or issues in the wall, the microcontroller activates a touch enabled display unit 126 attached on the base 101 to continuously displays noise level at location of defect to allow the user to control a quantity of glass wool 109 and sheet installed to reduce noise from the defect. The display unit 126 works by using LCD (liquid crystal Display) that are manipulated by electric currents to control the passage of light through the display unit 126. 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 126 regarding the areas of weakness or issues to aid the user to control a quantity of glass wool 109 and sheet installed to reduce noise from the defect.

[0029] Based on indicating areas of weakness or issues in the wall, an articulated L-shaped telescopic link 116 integrated with the base 101 to move a laser Doppler vibrometer 115 provided at an end of the link 116 to assist the sensor in measuring vibrations in the wall surface. The articulated L shaped telescopic link 116 is equipped with a pneumatic unit that is activated by the microcontroller to provide extension and retraction of the link 116 to allow the vibrometer 115 to detects vibrations on the wall surface. The pneumatic unit mentioned herein 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 link 116. 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.

[0030] 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. The piston is connected to the cylinder and due to the increase in the air pressure, the piston moves. 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 movement of the piston in a to and fro direction that turns in extending and retracting the link 116 to adjust the vibrometer 115 towards the wall. The vibrometer 115 works by measuring vibrations or oscillations on the wall surface using a sensitive detection mechanism. The vibrometer operates through a piezoelectric sensor or a laser-based system that detects minute displacements caused by vibrations. The detected signals are converted into electrical signals, which are then processed to determine the vibration frequency, amplitude, and intensity. This data is analysed by the microcontroller to ensure precise identification of areas requiring repair.

[0031] The data from both the noise sensor and the laser Doppler vibrometer 115 are synchronized to analyse and detects regions of the wall where the wall gets defected as per database having abnormal noise levels caused by excessive vibrations. the microcontroller actuates four sets of tri-wheel assemblies 102 mounted underneath the base for a locomotion of the base 101 towards the defected wall. The tri-wheel assemblies 102 work by using a cluster of three wheels mounted on a rotating hub, allowing the tri-wheels to navigate over the surface. Each tri-wheel cluster is powered by an independent motor, enabling precise control and manoeuvrability. The rotating hub allows the wheels to pivot, ensuring continuous ground contact for reaching the detected abnormal noise levels. Simultaneously, the microcontroller actuates a scissor lift 104 integrated with the base 101 to lift a platform 103 towards the detected wall.

[0032] The scissor lift 104 mentioned herein works by using a series of interlinked, crisscrossing metal supports that expand and contract in a scissor-like motion to raise or lower the platform 103. The scissor lift 104 is actuated by a motorized mechanism, such as a hydraulic cylinder, lead screw, or electric actuator, which applies force to the base 101 of the scissor structure. When activated by the microcontroller, the actuator pushes the supports outward, causing the platform 103 to rise smoothly enabling the platform 103 to reach the required height for inspection or repair of the detected defects in the wall.

[0033] Upon positioning the platform 103 near the defects of the acoustic wall, the microcontroller actuates another pneumatic unit integrated with an inverted U-shaped telescopic frame 107 associated with an insulation unit 106 assembled on the platform 103 to extend and retract to adjust a motorized primary roller 108 integrated with the frame 107 in contact with the defected wall. Herein, the primary roller 108 contains a spool of glass wool 109. The extension and retraction of the frame 107 adjust the roller 108 in contact to the wall. Simultaneously, the microcontroller actuates the roller 108 to rotate the roller 108 for unwrapping the wool 109 to apply over the wall through adjustment of the roller 108 via extension and retraction of the frame 107 that aids the wall to absorb noise that strikes over the wall from the surrounding by acting as soundproof for the wall.

[0034] Upon unrolling of the wool 109 over the wall, the microcontroller actuates another pneumatic unit integrated with an articulated L-shaped telescopic bar 110 assembled on the platform 103 to push an articulated extendable plate 111 integrated with the bar 110 on the wool 109 so as to pressurize and apply the glass wool 109 on the defect. Simultaneously, the microcontroller actuates a drawer mechanism integrated with the plate 111 to adjust size of the plate 111 to push all section of wool 109 with the wall. The drawer mechanism comprises of a carriage assembly and a DC (direct current) motor that works in collaboration to extend and retract the plate 111. The carriage assembly fitted with two rails that are used for sliding the block up and down.

[0035] The block opening located at the end of the rail and have two clips that are used to secure the ring with the plate 111. To extend the drawer, the drawer is pushed to open and the carriage assembly slide outward. This creates an opening to allow extension and retraction of the plate 111 to push the wool 109 into the defect. For instance, if a specific defect area registers a higher noise level, the display unit 126 might show a visual representation of the noise intensity (e.g., a color-coded map or decibel values), enabling the user to add more glass wool 109 or adjust the sheet placement for optimal noise reduction to ensures precise and efficient acoustic treatment.

[0036] Once, the wool 109 applied over the wall, the microcontroller actuates another pneumatic unit integrated with articulated L-shaped pole 113 for extending to position a cutter 114 integrated with the pole 113 in contact with the wool 109 and then the cutter 114 gets activated to cut the dispensed glass wool 109. After the cutting of the glass wool 109, the microcontroller actuates a pair of robotic arms 118 provided on the platform 103 to select the sheet from a sectioned chamber 117 provided on the platform 103 that is wrapped in motorised secondary rollers integrated in the chamber 117 having a thickness as per detected noise calculated by an ultrasonic sensor embedded on the platform 103, wherein the ultrasonic sensor detects the thickness of the sheet wrapped with the rollers.

[0037] The ultrasonic senor mentioned herein works by emitting high-frequency sound waves and measuring the time it takes for the reflected waves to return after hitting the sheet’s surface. This time-of-flight measurement allows the sensor to calculate precise distances and identify the sheet’s boundaries and contours. Based on the sheet’s boundaries and contours, the sensor calibrates the data to detect the thickness of the fabric. Based on detection, the microcontroller matches the detected thickness of the sheet with a thickness required for the detected noise. And after that the microcontroller actuates the robotic arm to grip the desired thickness sheet from the roller 108 and unwrap the sheet up to the desired thickness.

[0038] Simultaneously, the microcontroller actuates a sliding unit 120 installed on an inverted U-shaped structure 121 integrated front of the chamber 117 to translate the laser cutter 119 over the sheet to cut the sheet. The sliding unit 120 comprises of a rail unit that provides a guided path for linear movement. The rail unit usually includes a pair of parallel rails or tracks, along which the sliding unit 120 moves. The slider carriage, also called a stage or platform 103 equipped with a mechanism to minimize friction and ensure smooth motion. The sliding unit 120 incorporates a motor and a drive mechanism to generate linear motion. The motor is connected to a drive mechanism, such as a belt, lead screw, or ball screw. The drive mechanism converts the rotational motion of the motor into linear motion, propelling the slider carriage along the rail unit to translate the laser cutter 119 over the sheet.

[0039] Once the laser cutter 119 translating, the cutter 119 cuts the sheet up to the desired thickness. The laser cutter 119 works by focusing a high-energy laser beam onto the sheet, generating intense heat that melts, burns, or vaporizes the sheet along the cutting path to cut the sheet up to the desired thickness. After the cutting operation, the robotic arms 118 place the sheet on the defect filled with wool 109. The microcontroller now actuates a magnetic articulated L-shaped gripper 123 provided on the platform 103 to grip a fastener from a fastener receptacle 122 provided on the platform 103 and positions on the sheet. The gripper 123 works by using a combination of magnetic force and precise articulation to securely hold and accurately place the fastener on the sheet.

[0040] Simultaneously, the microcontroller generates commands to actuate an articulated L-shaped limb 124 located on the platform 103 to position a power ratchet 125 integrated with the limb 124 over the fastener that is griped and placed by the magnetic articulated L-shaped gripper 123. After the placement of the power ratchet 125 in contact with the fastener, the microcontroller actuates the power ratchet 125 to affix the fastener on the sheet and the acoustic wall. The power ratchet 125 works by using a high-torque rotational mechanism powered by an electric or pneumatic motor, applying precise and consistent torque to tighten the fastener effectively by ensuring a secure and durable connection for installation of the sheet with the defected wall.

[0041] During installation of the sheet with the defected wall, multiple proximity sensors synced with the imaging unit 105 installed on the plate 111 and arms 118 detects the movement over the wool 109. The proximity sensor works by emitting an electromagnetic field or signal, such as infrared light or ultrasonic waves, and measuring the reflection or disruption of that signal when the sheet or the wool 109, moves within the sensor's range. This allows the sensor to accurately track the position of the sheet relative to the wool 109, ensuring precise placement and preventing damage or misalignment during the installation process of the wool 109 and sheet onto defects in the acoustic wall.

[0042] Once the installation of the acoustic wall, the microcontroller actuates an articulated L-shaped member 127 having a motorised brush 112 at an end for cleaning of the wall after installation of the sheet. The member 127 is designed to reach and move across the wall surface, and the motorized brush 112 to rotate at high speed to remove dust, debris, or residue left from the installation process for ensuring a clean and finished appearance. Herein, a dust sensor is embedded in the platform 103 that detects the dust released from the sheet installed over the wall. The dust sensor operates by using optical or infrared technology to measure particulate matter in the air due to cleaning of the installed sheet with wall, detecting changes in light scattering caused by dust particles and providing real-time data to detect the dust generated during the installation.

[0043] Based on amount of dust detected, the microcontroller actuates a vacuum unit installed with the member 127 for withdrawing dust generated during the installation. The vacuum unit works by creating a powerful suction force using a motor-driven fan to generate negative pressure, drawing in air along with dust particles through an intake nozzle. The collected dust is then filtered and stored in a containment unit, ensuring a clean workspace and reducing airborne particulates during the installation process of the sheet with the acoustic wall.

[0044] 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.

[0045] The present invention works best in following manner that includes the base 101 having the artificial intelligence-based imaging unit 105 to detect structural defects in an acoustic wall including gaps, cracks present in acoustic walls and record location of the defects within a facility in a database linked with the microcontroller, as detected by the GPS (global positioning system). After that the noise sensors in synchronisation with a laser Doppler vibrometer 115 to detect regions of the plant with detected defects as per the database having abnormal noise levels caused by excessive vibrations to trigger the microcontroller to actuate the tri-wheel assemblies 102 to translate the base 101 to the defect, the frame 107 to extend and the primary roller 108 to dispense glass wool 109 on the defect, the bar 110 to push the wool 109 into the defect for absorbing sound and the pole 113 to extend and cut the dispensed wool 109 by the cutter 114. After that the robotic arms 118 selects a sheet having a thickness as per detected noise, measured by the ultrasonic sensor and the laser cutter 119 to cut dispensed sheet. After that the arms 118 place the sheet on the defect filled with wool 109. Simultaneously, the magnetic articulated L-shaped gripper 123 pics the fasteners and positions on the sheet on the wall. After that the articulated L-shaped limb 124 having a power ratchet 125 at an end affixes the fastener on the sheet and the acoustic wall.

[0046] Although the field of the invention has been described herein with limited reference to specific embodiments, this description is not meant to be construed in a limiting sense.
