Description:FIELD OF THE INVENTION

[0001] The present invention relates to an electronic gadget evaluation and trade-in assessment device that is developed for the inspection, evaluation, and assessment of the condition of electronic gadgets, particularly for resale or trade-in purposes, thereby ensuring fair and accurate results.

BACKGROUND OF THE INVENTION

[0002] When people sell their old phones or gadgets at a store, the condition of the gadget plays a big role in deciding its value. Traditionally, store staff or technicians check the device by hand—using simple tools like screwdrivers, flashlights, or even just their eyes to look for damage. They write down the details on paper or on a computer and try to give an estimated price. But this process is slow, inconsistent, and heavily depends on who is doing the checking. One technician might notice small cracks or battery issues, while another might miss them completely. This not only creates confusion but also makes customers feel unsure about whether they’re getting a fair deal. It’s also easy for mistakes to happen, especially if the gadget has hidden issues that can’t be spotted easily. Because of this, the traditional method often leads to delays, disagreements, and sometimes even lost trust between the store and the customer.

[0003] In the early days of second-hand electronics, when gadgets like early mobile phones were resold, the most common method for assessing the gadgets condition was visual inspection. Store employees look for obvious damage like cracks, scratches, or dents. However, this only evaluate the external condition, and no in-depth tests were done on internal components. So, people also use external tools like specialized testers for batteries and screens. These tools measure battery charge cycles and display brightness, and also verify if the touchscreen was working properly. For example, a tester uses a light meter to assess the screen's brightness or a battery analyzer to check its remaining capacity. While these methods were an improvement over visual inspection, they might still only test a few basic functions like battery health or screen responsiveness. They missed many critical issues, especially internal component failures.

[0004] US7970713B1 discloses about an invention that includes an automatic pricing method and apparatus for use in electronic commerce environments is described. Automatic pricing uses live price testing to estimate and measure demand for specific products—taking into account where appropriate, a vendor selected segmentation scheme. The results of live price testing are compared using a vendor selected goal function, e.g. profit maximization, to select a new price. A goal function that balances short term gains versus long term gains based on customer lifetime value is described. The live price testing approach used is designed to minimize losses due to price testing through statistical methods. Additionally, methods for distributing price testing across time so as to avoid problems caused by too many ongoing tests as well as side effects from testing are described. The selected price is a win for both purchasers and vendors as the automatic price will approximate the efficiency of a reverse auction without the inconvenience of the auction format while being goal maximizing for the vendor. For example, a vendor that normally sets prices of items for sale to customers can use embodiments of the invention to great effect.

[0005] US5873069A discloses about an invention that includes an enterprise-wide integrated computer system for storing, processing and reporting pricing information regarding a plurality of products in a plurality of stores in a plurality of markets, including a pricing function for pricing and re-pricing products responsive to market price changes. Pricing and re-pricing are accomplished on a product-by-product and a market-by-market basis.

[0006] Conventionally, many devices have been developed that are capable of performing inspection, evaluation, and assessment of the condition of electronic gadgets. However, these existing devices are incapable of carrying out inspection that test both the external and internal components of the gadgets. Additionally, these existing devices also fail in ensuring that the gadget being inspected matches the user's profile and details entered into the device.

[0026] The structure 101 is installed with a touch interactive display panel 102 that facilitates user in providing touch input command regarding electronic gadget. The touch interactive display panel 102 as mentioned herein is typically an LCD (Liquid Crystal Display) screen that presents output in a visible form. The screen is equipped with touch-sensitive technology, allowing the user to interact directly with the display using their fingers. A touch controller IC (Integrated Circuit) is responsible for processing the analog signals generated when the user inputs details regarding electronic gadget. A touch controller is typically connected to the microcontroller through various interfaces which may include but are not limited to SPI (Serial Peripheral Interface) or I2C (Inter-Integrated Circuit).

[0027] The device incorporates a distinctive user authentication process wherein a 4-digit code is generated by the computing unit, which is then entered by the user via the display panel 102. Upon receiving the code, the microcontroller cross-references the code with the user’s profile to verify the accuracy of the device identification and ensure proper matching during the inspection process. This authentication step guarantees that the device being inspected corresponds to the user’s details, thereby preventing errors, fraud, or misidentification and ensuring the integrity of the evaluation procedure.

[0028] A horizontal conveyor assembly 103 positioned on the upper portion of the cuboidal structure 101, which is specifically designed to facilitate the transport of an electronic gadget. Once the user places the gadget onto an entry tray 104, the conveyor assembly 103 moves the gadget along the assembly 103 to subsequent stages of inspection. This configuration ensures seamless handling and transportation of the gadget, providing both ease of use and efficient flow during the inspection process. The conveyor assembly 103 is engineered to support the precise and smooth movement of the electronic gadget for evaluation without risk of damage.

[0029] The conveyor assembly 103 operates by utilizing a motor that drives a series of rollers or belts positioned along the top portion of the structure 101. When a user places the gadget onto the entry tray 104, the conveyor assembly 103 is activated, causing the tray 104 to move along the assembly towards the designated inspection sections. The movement is controlled by the microcontroller to ensure the gadgets is transported accurately to the appropriate stage for inspection. This ensures smooth, consistent transport of the gadget, minimizing delays and ensuring precise positioning for further evaluation.

[0030] The conveyor assembly 103 is subdivided into multiple distinct sections, specifically a first and second inspection section, each designed to accommodate a particular stage of inspection for the gadget being processed. Above each conveyor stage, a U-shaped member 105 is strategically positioned to facilitate and support the specific inspection process assigned to each section. These sections are dedicated to performing separate, specialized inspection functions on the gadget, ensuring that each stage of the inspection process is carried out efficiently and accurately.

[0031] A motorized dual-axis slider assembly 106 is affixed to the ceiling portion of the aforementioned member 105 and is driven by the microcontroller, which actuates the motorized dual-axis slider assembly 106 to position a plate 107 attached to the slider assembly 106 via a pneumatic rod 108 directly over the electronic gadget. This arrangement ensures precise placement and movement of the plate 107 in relation to the gadget, allowing for accurate and controlled inspection or operation.

[0032] The dual-axis motorized slider assembly 106 consists of two axes of motion, typically arranged perpendicular to each other, allowing movement in both horizontal and vertical directions. The slider assembly 106 is controlled by the microcontroller. At its core, the slider assembly 106 consists of a motorized arrangement that drives the translation of the rod 108 suspended from it. This arrangement may utilize stepper motors, servo motors, or other motor types, depending on the design requirements. The microcontroller sends signals to the motorized slider, dictating the precise movements required for positioning the plate 107 attached via the rod 108, accurately over the gadget.

[0033] Synchronously, the rod 108 is pneumatically actuated, wherein the pneumatic arrangement of the rod 108 comprises of a cylinder incorporated with an air piston and the air compressor, wherein the compressor controls discharging of compressed air into the cylinder via air valves which further leads to the extension/retraction of the piston. The piston is attached to the telescopic rod 108, wherein the extension/retraction of the piston corresponds to the extension/retraction of the rod 108. The actuated compressor allows extension of the rod 108 to position the plate 107 over the gadget.

[0034] The plate 107 is installed with an artificial intelligence-based imaging unit 109 that is paired with an onboard optical sensor, and analyze surface of the gadget for fine scratches, dents, cracks, and surface wear. The imaging unit 109 disclosed herein comprises of an image capturing arrangement including a set of lenses that captures multiple images of surface of the gadget and the captured images are stored within memory of the imaging unit 109 in form of an optical data.

[0035] The imaging unit 109 also comprises of the processor which processes the captured images. 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 from the visual data which are processed by the microcontroller to analyze surface of the gadget for fine scratches, dents, cracks, and surface wear.

[0036] The optical sensor disclosed herein 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 surface of the gadget. If there is scratches, dents, cracks, and surface wear over surface of the gadget, 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, analyze surface of the gadget for fine scratches, dents, cracks, and surface wear.

[0037] A robotic arm 110 is operatively mounted on the left inner wall of the inspection enclosure and is equipped at its distal end with a rubber stylus 111 specifically configured to interface with the touchscreen of the accommodated electronic gadget. The robotic arm 110 executes a sequence of movements whereby the stylus 111 engages the gadget’s touchscreen interface to navigate through its user interface, specifically accessing the settings menu for the purpose of retrieving and recording the International Mobile Equipment Identity (IMEI) number and the Serial Number of the gadget, thereby facilitating automated identification and verification processes.

[0038] The robotic arm 110 used herein mainly comprises of motor controllers, arm, end effector and sensors. The arm is the essential part of the robotic arm 110 and it comprises of three parts the shoulder, elbow and wrist. All these components are connected through joints, with the shoulder resting at the base of the arm 110, typically connected to the microcontroller. The elbow is in the middle and allows the upper section of the arm to move forward or backward independently of the lower section. Finally, the wrist is at the very end of the upper arm and attaches to the end effector. The end effector connected to the arm acts as a hand and acquire a grip of the rubber stylus 111 to interacts with gadget’s touchscreen to navigate to gadget’s settings for retrieving IMEI and Serial number of the gadget.

[0039] An Optical Character Recognition (OCR) module is operatively integrated with the aforementioned member 105 and functionally synchronized with the imaging unit 109 positioned therein. The OCR module is configured to process visual data captured by the imaging unit 109, particularly that which corresponds to the displayed IMEI and Serial Number on the touchscreen of the electronic gadget. Upon synchronization, the OCR module executes recognition protocols to interpret alphanumeric characters from the captured image data, thereby digitally extracting and converting the displayed IMEI and Serial Number into machine-readable format for subsequent validation, logging, or processing within the member 105.

[0040] The OCR module receives high-resolution image data from the synced imaging unit 109, capturing the portion of the touchscreen displaying the IMEI and Serial Number. The OCR module preprocesses the image to enhance contrast, remove noise, and align character orientation. The module then segments the image into text zones, isolating individual characters using contour analysis. Utilizing trained recognition protocols and character mapping libraries, the OCR engine identifies each character and assembles them into a complete string. The extracted alphanumeric data is then converted into digital text format and transmitted to the microcontroller for storage, verification, or further automated processing.

[0041] The microcontroller herein cross-references the retrieved IMEI and Serial Number against a blockchain-based database maintained for the purpose of verifying the authenticity and ownership status of electronic gadgets. Upon successful extraction of the data via the OCR module, the microcontroller initiates a secure query to the decentralized ledger, wherein immutable records pertaining to legitimate devices are stored. The microcontroller then compares the retrieved identifiers with the corresponding entries within the blockchain to determine whether the subject gadget is flagged as stolen, counterfeit, or unauthorized, thereby ensuring compliance with authenticity verification protocols prior to further processing or approval.

[0042] Further the robotic arm 110 performs a touchscreen responsiveness test, wherein the stylus 111 engages with the screen of the gadget to simulate user input and assess screen accuracy and functionality. During this process, the imaging unit 109 monitors the touchscreen's response in real-time, detecting any instances of stuttering, input lag, or unregistered touches. The data captured is analyzed to determine whether the gadget's touchscreen meets predefined performance criteria, ensuring operational integrity and responsiveness before the gadget proceeds to the next stage of inspection or processing.

[0043] A plurality of microphone units 112 is disposed on the inner portion of the member 105, each configured to capture and record audio output emitted from the speaker of the accommodated electronic gadget. Correspondingly, a set of speaker units 113 is operatively positioned to emit predefined audio signals directed toward the gadget’s microphone. This arrangement facilitates a bidirectional audio functionality test, wherein the microphone units 112 evaluate the speaker performance of the gadget by recording its audio output, while the speaker units 113 assess the operational integrity of the gadget’s microphone by transmitting standard audio inputs, thereby enabling comprehensive acoustic diagnostics within the inspection process.

[0044] The microphone units 112 activate upon receiving a signal from the microcontroller and begin capturing acoustic signals produced by the gadget’s speaker. Each microphone converts sound waves into corresponding electrical signals, which are transmitted to the microcontroller for analysis. The recorded data is evaluated against predefined frequency, amplitude, and clarity thresholds to determine the fidelity and strength of the gadget's speaker output. Background noise is filtered using embedded noise-cancellation protocols to ensure accuracy. The results are logged and used to verify compliance with audio performance standards.

[0045] The speaker units 113 are triggered by the microcontroller to emit predefined audio signals across various frequencies and volumes. These signals are directed toward the gadget’s onboard microphone to test its responsiveness and accuracy. The gadget’s microphone captures the incoming signals and relays them back through its internal processing unit. The recorded feedback is analyzed by the microcontroller to assess distortion, signal loss, or delay. The speaker units 113 operate in a controlled sequence to ensure consistent input and enable precise evaluation of the gadget’s microphone functionality.

[0046] On the right inner wall of the member 105 a robotic gripper 120 is installed to rotate the gadget to inspect back side of the gadget. The robotic gripper 120 includes a link connected with multiple motorized ball and socket joints and a gripper 120 for smooth and precise gripping of gadget. The motorized ball and socket joint includes a motor powered by the microcontroller generating electrical current, a ball shaped element and a socket. The ball move freely within the socket. The motor rotates the ball in various directions that is controlled by the microcontroller that further commands the motor to position the ball precisely. The microcontroller further actuates the motor to generate electrical current to rotate in the joint for providing movement to the gripper 120 for rotating the gadget to inspect back side of the gadget.

[0047] An articulated robotic link 114 is integrated with a heat gun 115, which is positioned on the inner portion of the second inspection section. The heat gun 115 is specifically designed to gently heat the surface of the electronic gadget, applying controlled heat to soften the adhesive securing the screen or back cover of the gadget.

[0048] This process facilitates the removal or adjustment of the screen or back cover without causing damage to the underlying components. The articulated robotic link 114 works similarly as of robotic arm 110 and ensures precise movement and positioning of the heat gun 115, maintaining consistency and accuracy during the adhesive softening process to enable further inspection or maintenance.

[0049] The heat gun 115 emits a focused stream of warm air directed at the surface of the gadget. The temperature is carefully regulated to ensure that it is sufficient to soften the adhesive without damaging the gadget’s components or affecting the integrity of the screen or back cover. The heat is applied evenly, with the robotic link 114 ensuring the heat gun 115 is positioned at the optimal distance and angle. Once the adhesive reaches a softened state, the heat gun 115 is deactivated to prevent overheating.

[0050] Simultaneously, the microcontroller directs the actuation of an extendable link 116 which is integrated with a suction cup 117 to gently lifts screen/ back panel without scratching or cracking. The link 116 is pneumatically actuated, and works in the similar manner as of rod 108 mentioned above. On getting actuated, the link 116 extends and positions the suction cup 117 on the gadget in order to gently lifts screen/ back panel without scratching or cracking.

[0051] The suction cup 117 creates a vacuum seal between the cup and the surface of the screen or back panel. Once applied, the suction cup 117 securely adheres to the surface with consistent pressure, ensuring a firm grip. The extendable link 116 then gently lifts the screen or back panel, applying even force to avoid damage. Once the panel is sufficiently lifted, the suction cup 117 grip is released, allowing for safe detachment. The entire process ensures that the surface of the gadget remains free from scratches or cracks during the lifting procedure.

[0052] A motorized screwdriver tool 118 is positioned within the second inspection section, wherein the tools is automatically moved into precise alignment by the microcontroller to engage with and unscrew internal screws securing the components of the electronic gadget. The screwdriver tool 118 is specifically designed to operate with a controlled torque, ensuring that screws are efficiently removed without damaging the surrounding components or the screw threads. The automatic positioning and movement of the motorized screwdriver tool 118 enable precise and consistent operation, facilitating the disassembly of the gadget for subsequent inspection or repair without manual intervention.

[0053] The motorized screwdriver tool 118 motor generates rotational force, which is transferred to the screwdriver bit to turn and unscrew the fasteners. The torque applied is carefully controlled to prevent over-tightening or damaging the screws and surrounding components. The screwdriver tool 118 bit engages with the screw, rotating it counterclockwise until the screw is fully removed. Once the screw is detached, the screwdriver tool 118 retracts automatically, ready for further positioning to unscrew additional fasteners if necessary.

[0054] A thermal camera 119, synchronized with an ultrasonic sensor, is integrated within the second inspection section to detect hidden internal issues within the electronic gadget, such as battery swelling, overheating, or other structural abnormalities. The thermal camera 119 captures temperature variations across the surface of the gadget, while the ultrasonic sensor provides data related to structural integrity, enabling the device to identify potential faults that are not visible to the naked eye.

[0055] The thermal camera 119 detects infrared radiation emitted by the electronic gadget, converting it into a thermal image. The camera 119 measures temperature variations across the gadget's surface, highlighting areas with abnormal heat patterns. Hot spots indicating overheating or excessive heat accumulation are visually represented, enabling precise identification of potential faults, such as battery swelling or malfunctioning components.

[0056] The ultrasonic sensor emits high-frequency sound waves toward the internal components of the gadget. These sound waves travel through the gadget and are reflected back to the sensor upon encountering different materials or structure. The sensor measures the time it takes for the sound waves to return, using this data to assess the density, thickness, and integrity of internal components. Variations in the reflected sound waves indicate abnormalities, such as potential structural issues, hidden defects, or battery swelling. The sensor provides continuous feedback, which is analyzed to detect any issues that may compromise the gadget's functionality.

[0057] The screwdriver, suction cup 117, and heat gun 115 are each mounted on respective motorized ball-and-socket joints, allowing for multi-directional articulation and precise positional control. The motorized ball and socket joint mentioned here consists of a ball-shaped element that fits into a socket, which provides rotational freedom in various directions. The ball is connected to a motor, typically a servo motor which provides the controlled movement. The screwdriver, suction cup 117, and heat gun 115 is attached to the socket of the motorized ball and socket joint, the microcontroller sends precise instructions to the motor of the motorized ball and socket joint. The motor responds by adjusting the ball and socket joint and rotates the ball in the desired direction, and this motion is transferred to the socket that holds the screwdriver, suction cup 117, and heat gun 115. As the ball and socket joint move, it provides the necessary movement to the screwdriver, suction cup 117, and heat gun 115, thereby enabling them to achieve the correct angle for each inspection step.

[0058] The microcontroller, upon completion of the inspection process and based on the analyzed internal and external condition parameters of the electronic gadget, is programmed to compute a trade-in offer reflective of the device’s assessed value. This valuation is determined through predefined criteria, thereby ensuring consistency and objectivity in price estimation. The calculated trade-in offer is then electronically rendered and communicated to the user via the display panel 102, thereby facilitating a direct and transparent conveyance of the assessment outcome.

[0059] The microcontroller is configured to perform a comparative analysis between the condition data and images captured during the inspection process and the corresponding information previously submitted by the user. Upon detection of any inconsistencies or discrepancies between the actual physical condition of the electronic gadget and the user-provided data, the microcontroller is programmed to generate and display an alert notification on the user interface. Conversely, if the captured condition aligns with the pre-uploaded user inputs, the microcontroller is operatively set to proceed with the subsequent stages of inspection without interruption. This functionality ensures data integrity, prevents misrepresentation, and supports an accurate and reliable assessment process in accordance with standard verification protocols.

[0060] Moreover, a battery is associated with the device for powering up electrical and electronically operated components associated with the device and supplying a voltage to the components. The battery used herein is preferably a Lithium-ion battery which is a rechargeable unit that demands power supply after getting drained. The battery stores the electric current derived from an external source in the form of chemical energy, which when required by the electronic component of the device, derives the required power from the battery for proper functioning of the device.

[0061] The present invention works best in the following the manner, where the cuboidal structure 101 as disclosed in the invention is configured to be installed within the retail or service store environment configured to inspect and assess condition of electronic gadgets for resale. The user-interface is inbuilt in the computing unit accessed by the user to create profiles, input details about the gadget, upload photos of the gadget, and choose between the store visit or pickup service for device inspection. The touch interactive display panel 102 allows the user to provide input details regarding the electronic gadget. The device incorporates the unique user authentication process, where the 4-digit code is generated over the computing unit that is prompted by the user over the display panel 102 the microcontroller cross-checks with the user’s profile to ensure accurate identification and matching of the device during inspection. Then the horizontal conveyor assembly 103 transport the electronic gadget placed by the user onto the entry tray 104. And the conveyor assembly 103 is divided into multiple sections, namely first and second inspection section. The U-shaped member 105 is positioned above each conveyor stage, each section dedicated to the specific inspection process of the accommodated gadget. The motorized dual-axis slider assembly 106 mounted on the ceiling portion of the member 105 to position the plate 107 attached with slider via the pneumatic rod 108 over the electronic gadget.

[0062] In continuation, the artificial intelligence-based imaging unit 109 analyze surface of the gadget for fine scratches, dents, cracks, and surface wear. The robotic arm 110 equipped with the rubber stylus 111, which interacts with gadget’s touchscreen to navigate to gadget’s settings for retrieving IMEI and Serial number of the gadget. Thereafter the OCR (Optical Character Recognition) module read the retrieved IMEI and Serial number. Also, the robotic arm 110 performs the touchscreen responsiveness test, where the stylus 111 interacts with screen of the gadget to simulate user input and tests for screen accuracy and functionality, checking for stuttering or lag via the imaging unit 109. Plurality microphone units 112 record audio output from gadget’s speaker and the speaker units 113 play predefined audio signals to test gadget’s microphone. The robotic gripper 120 rotates the gadget to inspect back side of the gadget.
