Description:FIELD OF THE INVENTION

[0001] The present invention relates to a contactless reading materials management device that allows contactless, organized, and efficient access to reading materials, while ensuring real-time monitoring and updating of material availability for accurate management.

BACKGROUND OF THE INVENTION

[0002] The need for contactless reading in materials management arises from the growing demand for speed, accuracy, and efficiency in tracking and handling inventory. Managing a high volume of materials requires precise monitoring to ensure the right components are available at the right time. Contactless reading enables real-time visibility of materials without manual intervention, reducing errors in identification and counting. Additionally, in environments where hygiene, safety, or contamination control is critical contactless readings help maintain clean and secure handling. By eliminating the need for physical scans or contact-based inputs, contactless reading improves operational speed.

[0003] Traditional methods of delivering reading material, including personalized news feeds, often relied on manual content curation, email newsletters, or basic keyword-based filtering systems. These approaches required users to subscribe to general categories or sources, receiving a uniform feed regardless of specific interests or evolving preferences. Such systems lacked dynamic adaptability and failed to account for user behaviour or feedback in real time, leading to irrelevant or repetitive content. Additionally, manual curation was time-intensive and could not scale efficiently with increasing content volume. Users often had to navigate through multiple platforms or applications to access their desired news, resulting in fragmented reading experiences. Overall, traditional methods of personalized news delivery were less responsive, less accurate, and unable to meet the demand for real-time.

[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 a contactless reading materials management device that ensures real-time monitoring and updating of material availability while enabling automatic selection, retrieval, and delivery of printed reading materials based on user input, reducing manual handling and improving convenience.

[0023] Referring to Figure 1 and 2, an inner view a contactless reading materials management device and outer view of view the device are illustrated, respectively, comprising a housing 101 configured with at least four extendable support legs 102 fitted with a motorized omnidirectional wheel 103, a storage chamber 104 installed in the housing 101 having multiple compartments comprises a RFID (Radio frequency Identification) reader 105 installed in each of the compartment, an artificial intelligence-based imaging camera 106 installed in each compartment, an auto-sanitization unit 201 integrated within the compartment includes one or more UV-C (Ultraviolet-C) arrays 201a, an electrostatic dust collector 201b, an internal retrieval and delivery unit 107 installed in the housing 101 includes a two-axis motorized slider 107a installed on a ceiling portion of the chamber 104, a robotic gripper 107b installed on the slider.

[0024] Figure 1 and 2 further illustrates a bucket conveyer belt 108 positioned centrally in the chamber 104, an outlet 109 carved on a top portion of the housing 101, a platform 202 arranged on a top portion of the housing 101 comprises a motorized hinge joint 203, a page turning assembly 204 mounted on the top portion includes a motorized slider 204a arranged on lateral sides of the platform 202 assembled with an extendable L-shaped link 204b, a motorized gripper 204c installed on a free-end of the link, a lighting unit 205 installed on the top portion includes an L-shaped expandable frame 205a with a LED (Light Emitting Diode) lamp 205b, a monitoring unit 206 installed on the housing 101, a seating platform 207 arranged with the housing 101 having a retractable seat 207a mounted on an extendable bar 207b, a retractable acoustic cover 208 arranged with the housing 101, a robotic arm 209 installed on the housing 101 and microphone 210 installed on housing 101.

[0025] The device discloses herein includes a housing 101 configured with at least four extendable support legs 102 for dynamic height adjustment. The housing 101 is made from durable and lightweight materials such as aluminum alloy, high-strength plastic, or carbon fiber composites. These materials provide a strong, protective outer shell that withstands operational stresses while allowing for portability and maneuverability. The extension/retraction of the legs 102 is powered by a pneumatic unit associated with device, that includes an air compressor, air cylinder, air valves and piston which works in collaboration to aid in extension and retraction of the legs 102.

[0026] 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 is consisting 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. The piston is attached to the legs, wherein the extension/ retraction of the piston corresponds to the extension/ retraction of the legs 102 to position motorized omnidirectional wheel 103 for manoeuvrability. The motorized omnidirectional wheel 103 fitted on each extendable leg enable smooth movement in any direction. These wheel 103 feature small rollers mounted around their circumference at an angle, allowing them to roll forward, sideways, and diagonally. Each wheel 103 is powered by its own electric motor, which is controlled independently to coordinate precise movements.

[0027] An input means paired with the housing 101 and operatively coupled with an inbuilt microcontroller, for receiving user inputs regarding a preferred reading material. The input means herein is a user interface. The microcontroller activates an inbuilt communication module for establishing a wireless connection between the microcontroller and a computing unit that is inbuilt with the user-interface and accessed by the user for enabling the user to give input commands for preferred reading material and height adjustment of the leg. The user interacts with the interface through a touch screen, keyboard, or other input methods available on the computing unit. The computing unit mentioned herein includes, but not limited to smartphone, laptop, tablet.

[0028] The communication module mentioned herein includes, but not limited to Wi-Fi (Wireless Fidelity) module, Bluetooth module, GSM (Global System for Mobile Communication) module. The communication module used in the device is preferably the Wi-Fi module. The Wi-Fi module enables wireless communication by transmitting and receiving data over radio frequencies using IEEE 802.11 protocols. It connects to a network via an access point, converting digital data into radio signals. The module processes TCP/IP protocols for data exchange, interfaces with microcontrollers through UART/SPI, and ensures encrypted communication using WPA/WPA2 security standards for secure and efficient wireless connectivity.

[0029] The height adjustment is controlled via the input means, while the maneuverability is controlled by one or more integrated gyroscopic sensors, proximity sensors and a LIDAR (Light Detection and Ranging) module for ensuring safe navigation in crowded environments. The gyroscopic sensors measure the orientation and angular velocity of the device, allowing it to detect changes in direction, tilt, or rotation. This helps maintain stability and balance, especially when moving or adjusting height on uneven surfaces. The proximity sensors detect nearby objects without physical contact by emitting signals such as infrared or ultrasonic waves and measuring the time it takes for the signal to bounce back. This allows the device to recognize obstacles at close range and avoid collisions. The LIDAR module provides a detailed, real-time 3D map of the surrounding environment by emitting laser beams and measuring the time they take to reflect off surfaces. The LIDAR enables to detect objects, distances, and spatial layouts with high accuracy, even in complex or dynamic settings.

[0030] A storage chamber 104 installed in the housing 101 is constructed from strong yet lightweight materials like ABS plastic or aluminum alloy to provide durability and portability. The chamber 104 features multiple compartments that help organize reading materials. These compartments sort content based on publication date, language, region, and type of content, ensuring efficient storage and easy access to specific materials.

[0031] The storage chamber 104 further comprises one or more proximity sensors and optical counting sensors for tracking inventory that is automatically updated in a linked database upon dispensing or restocking. The proximity sensors function by emitting a signal such as infrared and detecting when an object interrupts or reflects this signal within a specific range. When an item is removed from or placed into a compartment, the proximity sensor detects the presence or absence of the object, allowing the microcontroller to recognize changes in inventory levels. The optical counting sensors use light-based technique typically laser beams to detect and count individual items as they are dispensed or restocked. These sensors often consist of a light emitter and a photodetector placed opposite each other; when an item passes through the beam, it momentarily blocks the light, triggering a count. Together, these sensors provide precise tracking of inventory movement, and the data collected is automatically updated in the linked digital database.

[0032] The RFID (Radio frequency Identification) reader 105 installed in each of the compartment, for identification of RFID tags attached to each printed material for real-time inventory updates. The RFID arrangement works through the interaction between the RFID reader 105 and RFID tags that are attached to each individual printed item. These tags contain a microchip and an antenna, and they store unique identification data. When a printed material is placed inside or removed from a compartment, the RFID reader 105 emits a low-power radio frequency signal that activates any nearby RFID tags. Once activated, the tag transmits its stored data back to the reader 105, which then identifies the specific item. This data is instantly processed and sent to the database, automatically updating inventory records without the need for manual scanning or counting.

[0033] An artificial intelligence-based imaging camera 106 linked with an OCR (Optical Character Recognition) module. The camera 106 comprises of an image capturing arrangement including a set of lenses that captures multiple images of the reading material, and the captured images are stored within memory of the camera 106 in form of an optical data. The camera 106 also comprises of a processor that is integrated with artificial intelligence protocols, such that the processor processes the optical data and extracts the required data from the captured images. The extracted data is further converted into digital pulses and bits.

[0034] Once the image is captured, it is sent to the OCR module, which is responsible for converting the visual text into machine-readable characters. The OCR works by analyzing the shapes and patterns of the letters and comparing them to known character templates to recognize the text. The module identifies a wide range of fonts, sizes, and languages, and also distinguish between text and images on a page and process text-based content efficiently for tasks such as inventory classification, content search, or archival.

[0035] Further, one or more environmental sensors for monitoring humidity and temperature to trigger maintenance alerts for preserving material quality. The Humidity sensors measure the amount of moisture in the air, often using capacitive or resistive sensing elements that change their electrical properties based on humidity levels. The temperature sensors, such as thermistors or digital thermal sensors, monitor ambient temperature with high precision. When either humidity or temperature exceeds or falls below pre-set thresholds that potentially damage sensitive materials such as causing paper to warp, degrade, or grow mold the sensors trigger automatic maintenance alerts. These alerts notify users to take corrective actions like activating dehumidifiers, adjusting storage conditions, or performing manual inspections.

[0036] An internal retrieval and delivery unit 107 installed in the housing 101 to retrieve a user-specified printed material from the chamber 104, to deliver the reading material to a platform 202 arranged on a top portion of the housing 101, to the user. The internal retrieval and delivery unit 107 includes a two-axis motorized slider 107a installed on a ceiling portion of the chamber 104. The motorized slider consists of two perpendicular linear actuators driven by stepper or servo motors that allow movement along both the X-axis (horizontal left-right) and the Y-axis (front-back) across the ceiling. The first motor controls movement along one axis, while the second motor, mounted on the first slider's carriage, moves along the second axis, forming a coordinated two-dimensional motion plane. A robotic gripper 107b is mounted at the intersection point of these two sliders, enabling it to traverse the entire ceiling area of the chamber 104 and access any compartment below for gripping reading materials.

[0037] The robotic gripper 107b functions as the key end-effector to securely handle and transfer reading materials such as books, magazines, or documents without causing damage. The gripper is equipped with soft-touch, rubberized or silicone-coated gripping pads mounted on articulated fingers or jaws, which are driven by small electric motors or pneumatic actuators. When the gripper is positioned precisely above the target material using the two-axis motorized slider 107a it lowers to align with the item. Once aligned, the gripper’s fingers close gently around the item, applying just enough pressure to securely hold it without bending or tearing the pages or covers. When a specific reading material is requested or scheduled for delivery, the microcontroller uses data from the RFID reader 105 and OCR module to accurately identify its location. The microcontroller then calculates the shortest path for the gripper and activates the motors to move the slider to the target position. Once above the designated compartment, the robotic gripper 107b lowers, securely grips the reading material delivers the material to a bucket conveyer belt 108 positioned centrally in the chamber 104.

[0038] The bucket conveyer belt 108 is configured to transport retrieved reading materials to an outlet 109 carved on a top portion of the housing 101, positioned adjacent to the platform 202. The bucket conveyor belt consists of a continuous looped belt with evenly spaced buckets attached to it, each capable of securely holding individual reading materials during transit. Once the robotic gripper 107b places a reading material into one of the buckets, the conveyor is activated, and the belt begins to move vertically. The movement is powered by an electric motor connected to a drive pulley, while tension is maintained using an idler pulley at the opposite end. As the belt moves, the buckets carry the items upward toward the outlet 109 carved into the housing 101, where the material is gently released or presented for further handling. Once the material reaches the outlet 109, it becomes accessible to a robotic arm 209 installed near the opening. This arm then grips the material and places it precisely onto the platform 202 for user access.

[0039] The robotic arm 209 contains an end effector and several segments that are attached together by motorized joints also referred to as axes. Each joint of the segments contains a step motor that rotates and allows the robotic arm 209 to complete a specific motion in translating the equipped end effector. The end effector further comprises of a pair of jaws hinged with each other by means of a bi-directional step motor. On actuation the step motor rotates and enables the opening/closing of the jaws of the effector for releasing/gripping the reading material.

[0040] The bucket conveyer belt 108 is integrated with at least one position sensor, optical encoders and infrared sensor for confirming arrival and safe delivery upon validation of the user selection and presence. The position sensors detect the precise location of objects or components along a path. For example, a magnetic position sensor detects magnets or metal parts attached to the buckets or conveyor structure. When the sensor passes over these markers, it registers a signal indicating the bucket’s position. This allows to know exactly where each bucket is at any moment, helping coordinate loading, movement, and unloading operations. The optical encoders convert mechanical rotation into electrical signals for precise measurement of movement. They typically consist of a rotating disk with alternating transparent and opaque segments and a light source paired with a photodetector. As the disk spins attached to the conveyor motor or drive shaft the light beam is alternately blocked and allowed through, creating pulses. The encoder counts these pulses to determine how far the conveyor has moved, how fast it’s going, and the exact position of each bucket.

[0041] The infrared (IR) sensors use infrared light to detect objects or measure distance without physical contact. They emit an invisible IR beam from an LED transmitter, which is either reflected back by an object to a receiver (in reflective sensors) or interrupted by the object passing between the transmitter and receiver (in through-beam sensors). When a reading material enters a bucket, it interrupts or reflects the IR beam, signaling its presence. This helps confirm that the item has been loaded or delivered correctly.

[0042] The platform 202 further comprises a motorized hinge joint 203 for angle adjustment based on the user preferences. The motorized hinge joint 203 consists of two connected parts one attached to the platform 202 and the other to the housing 101 joined by a pivot axis that enables rotational movement. The motorized aspect is typically powered by a small electric motor, such as a stepper motor or a servo motor, which drives the rotation around the hinge axis. When the user inputs a desired angle, the motor receives a control signal and activates to move the platform 202 smoothly to that position. The high-friction gripping pads arranged on an upper surface of the platform 202 for securing the reading material. The high-friction gripping pads are made from rubber, silicone, or other elastomeric materials known for their excellent grip and durability. When a reading material is placed on the platform 202, the textured or tacky surface of the gripping pads increases the contact area and friction between the pad and the material, effectively “gripping” it without causing damage. This prevents the item from shifting even if the platform 202 tilts or moves. The softness and flexibility of the pads also help conform slightly to the shape of the reading material, distributing pressure evenly and enhancing grip.

[0043] A page turning assembly 204 mounted on the top portion to enable hands-free page turning for facilitating ease in reading, that is controlled by the user commands. The page turning assembly 204 includes a motorized slider 204a arranged on lateral sides of the platform 202 assembled with an extendable L- shaped link 204b. The slider consists of a rail or track and a carriage that moves along it, driven by an electric motor such as a stepper or servo motor connected to a lead screw, belt, or rack-and-pinion mechanism. When activated, the motor rotates, translating rotational motion into linear movement of the carriage along the slider. This controlled movement allows the extendable L- shaped link 204b to reach out towards the page edge precisely and with enough force to gently turn a single page without damaging it.

[0044] The extension of the link is powered by a pneumatic unit associated with device, that includes an air compressor, air cylinder, air valves and piston which works in collaboration to aid in extension/retraction of the link. 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 is consisting 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. The piston is attached to the link, wherein the extension of the piston corresponds to the extension of the link to position a motorized gripper 204c installed on a free-end of the link to allow the gripper to grasp and turn pages of the reading material, based on the user commands.

[0045] The motorized gripper 204c features small, delicate fingers or pads made from soft, high-friction materials like silicone or rubber to gently hold a single page without tearing or crumpling it. The gripper is powered by a small motor often a servo or stepper motor that controls the opening and closing motion of the fingers with precise force and timing. When the user issues a command to turn a page, the motorized slider 204a first moves the L- shaped link 204b to position the gripper at the edge of the current page. The gripper then closes gently to grasp the page, to apply just enough pressure to avoid damage. Once securely held, the motor controlling the gripper coordinates with the slider to pull and lift the page, turning it over smoothly. After completing the turn, the gripper releases the page and retracts to its resting position, ready for the next command.

[0046] A lighting unit 205 installed on the top portion, for illuminating the platform 202, to increase visibility for the user upon detection of low light conditions via an ambient light sensor installed on the platform 202. The ambient light sensor monitors the surrounding light levels to ensure optimal visibility for the user. This sensor typically operates using a phototransistor that detects the intensity of ambient light by measuring the amount of light that hits its surface. When the sensor detects that the light level falls below a predefined threshold indicating low or insufficient lighting conditions it sends an electrical signal to the microcontroller.

[0047] The lighting unit 205 includes an L-shaped expandable frame 205a with a LED (Light Emitting Diode) lamp 205b installed via motorized rotary joints for position and angle adjustment, to provide illumination in surroundings or on the platform 202, while the microcontroller regulates the light intensity via PWM control to minimize glare. The. LEDs work by passing an electric current through a semiconductor material, which then emits light. This makes LEDs highly efficient, long-lasting, and capable of producing bright, focused light with minimal heat generation. The LED lamp 205b brightness and color can be precisely controlled by the microcontroller using Pulse Width Modulation (PWM), a technique that rapidly switches the LED on and off at varying intervals to adjust perceived light intensity smoothly while minimizing glare and energy consumption.

[0048] The L-shaped frame 205a is connected through motorized rotary joints, which are powered by small electric motors such as servo or stepper motors. These joints allow the frame 205a and thus the LED lamp 205b to rotate and tilt along one or more axes, enabling precise adjustment of the lamp 205b position and angle. This flexibility ensures that the light can be directed exactly where it is needed, whether onto the reading material on the platform 202 or around the device for ambient lighting.

[0049] An auto-sanitization unit 201 installed on the housing 101 for maintaining hygiene of the reading materials. The auto-sanitization unit 201 comprises one or more UV-C (Ultraviolet-C) arrays 201a for sterilization. When the sanitization cycle is activated by user command the UV-C arrays 201a emit short-wavelength UV-C light that penetrates the cell walls of microorganisms and disrupts their DNA or RNA, rendering them inactive or unable to replicate. This process effectively neutralizes potential pathogens without the need for chemicals or physical contact.

[0050] An electrostatic dust collector 201b for trapping airborne particles. The dust collector 201b works by electrically charging airborne particles and then capturing them on oppositely charged collection plates. The unit consists of three main components: an ionizing section, a collection section, and a power supply. When air passes through the ionizing section, it flows past a series of thin wires or needles that are supplied with a high-voltage current. This creates a corona discharge that emits free electrons, which attach to airborne particles, giving them a negative electrical charge. The now-charged particles continue to flow into the collection section, which contains plates or surfaces with an opposite (positive) charge. Due to electrostatic attraction, the negatively charged particles are drawn toward and adhere to these plates, effectively removing them from the air. The cleaned air is then released back into the environment, while the dust and particles remain trapped on the plates, which is cleaned or replaced periodically.

[0051] Additionally, one or more IR (Infrared) sensors and ultrasonic sensors for detecting unoccupied states. The IR sensors detect heat emitted by objects, particularly human bodies, in the form of infrared radiation. Passive IR (PIR) sensors, commonly used for occupancy detection, consist of a pair of pyroelectric sensors that detect changes in infrared energy levels. When a person enters or leaves the monitored space, the sensor registers the shift in heat signature and sends a signal to the control unit. If no change is detected over a set period, the microcontroller determines that the area is unoccupied. The ultrasonic sensors work by emitting high-frequency sound waves that are inaudible to humans. These waves bounce off nearby objects and return to the sensor. By measuring the time, it takes for the echo to return, the microcontroller determines the presence and distance of objects or people in the space.

[0052] Further, one or more air quality and optical surface contamination sensors for assessing cleanliness. The air quality sensors monitor pollutants such as dust, smoke, pollen, volatile organic compounds (VOCs), and carbon dioxide (CO₂) in real time. These sensors use laser or infrared light scattering to detect and measure airborne particles by analyzing how they disrupt a focused light beam as they pass through it. The optical surface contamination sensors are used to detect dirt, smudges, or residue on key surfaces like the platform 202. These sensors work by emitting a light beam onto a surface and analyzing the reflected light clean surfaces reflect light uniformly, while contaminated ones scatter light irregularly, triggering alerts.

[0053] A monitoring unit 206 installed on the housing 101 comprising an artificial intelligence-based imaging unit and a gesture sensor for detecting the user’s presence, posture and gestures for monitoring user engagement. The imaging unit works in the similar manner as imaging camera 106 as discussed above. The gesture sensor emits infrared light pulses toward the user’s hand or body. These light pulses bounce off the user and return to the sensor. The sensor then measures the time it takes for the light to travel to the object and back this is known as the "time of flight." By calculating this time delay, the sensor builds a depth map or 3D representation of the space in front of it. The microcontroller then detects movements and shapes like a waving hand, swipe, or pinch by tracking changes in position and distance over time. Using this real-time depth data, the gesture sensor recognizes specific predefined gesture patterns.

[0054] A seating platform 207 arranged with the housing 101 having a retractable seat 207a mounted on an extendable bar 207b, adjustable backrest for providing support to the user during a reading session. The extendable bar 207b works in the similar manner as extendable link as discussed above. During the start of a reading session, the seat is deployed outward from the housing 101 using a linear actuator which pushes the seat into position for user access. The extendable bar 207b provides structural support and stability. The seat is mounted on a pivot or hinge that allows for a controlled movement during deployment and retraction. When the session ends, the motor is reactivated to retract the seat back into the housing 101. Additionally, the seat often includes an adjustable backrest, which can be tilted or repositioned for ergonomic support during use.

[0055] A retractable acoustic cover 208 arranged with the housing 101 and works in coordination with built-in microphone 210 that continuously monitor ambient sound levels. These microphone 210 detect noise by converting sound waves into electrical signals, which are then analyzed by the microcontroller to determine their intensity (measured in decibels). When the detected noise exceeds a pre-defined threshold, the microcontroller automatically triggers the deployment of the acoustic cover 208. The acoustic cover 208 is made from sound-absorbing materials such as multi-layered foam, dense fabrics, or composite acoustic panels that are designed to block or dampen external noise. The cover is mounted on a motorized retractable arrangement, such as a roll-out arm, which extends the cover around the user’s seating and reading area. As it deploys, it forms a partial enclosure or hood that isolates the user from surrounding distractions. By physically shielding the user and absorbing or deflecting external sounds, the acoustic cover 208 creates a quiet, focused microenvironment ideal for reading or concentration.

[0056] A payment unit integrated with the input means is designed to facilitate secure, contactless transactions for purchasing or borrowing reading materials or related services. The payment unit operates by combining QR code scanning, microcontroller processing, database validation, and payment gateway integration to ensure a seamless and traceable transaction flow. When a user initiates a purchase or access request, the microcontroller generates a unique QR code on the display screen, linked to the specific transaction (such as the item ID, price, and user credentials).

[0057] The user scans this QR code using a smartphone equipped with a digital payment app (e.g., UPI, Apple Pay, Google Pay, etc.). Upon scanning, the payment app redirects the user to a secure payment gateway, which processes the transaction using the user's linked bank or wallet account. Once the payment is processed successfully, the payment gateway sends a confirmation response back. This data is received and validated by the microcontroller, which checks for successful transaction status and cross-verifies it with the internal database to confirm user identity, transaction details, and item availability.
