Description:FIELD OF THE INVENTION

[0001] The present invention relates to a retail display device that is capable of securely showcasing products like electronic gadgets to ensure protection against unauthorized handling in retail environments, and assisting users in finding items based on their preferences, thus promoting enhanced user-experience.

BACKGROUND OF THE INVENTION

[0002] In retail environments, the presentation and display of electronic gadgets such as smartphones, tablets, and other portable devices play a crucial role in attracting customers and influencing purchasing decisions. Traditional display methods often involve glass cases, open shelving, or countertop displays where products are arranged for customers to view and handle. These displays are usually static and lack interactive features, providing only a limited overview of the gadgets’ appearance and basic functionalities. To enhance customer experience, many stores rely on staff members to assist with product demonstrations, answer questions, and retrieve specific models. While being helpful, this approach is inefficient, as it depends heavily on staff availability and may lead to long wait times for customers. Moreover, traditional displays do not easily support dynamic or personalized information, such as comparisons between models, current offers, or detailed specifications, which are increasingly important in today's competitive retail market.

[0003] Currently, most retail stores use simple display cabinets that are either locked or unattended, making it difficult for customers to freely explore or compare different products. To assist customers, staff members are usually needed to retrieve items, answer questions, or operate demonstration units. This approach leads to longer wait times, limited customer engagement, and a higher dependency on staff. Additionally, these displays do not incorporate advanced technologies to identify customer interest or to provide dynamic, personalized information, which limit the overall shopping experience and reduce sales opportunities. Furthermore, existing methods do not typically include mechanisms for secure interaction with high-value electronic gadgets or features for detecting unauthorized handling. They also lack automatic cleaning, gesture-based access, or eye-tracking to gauge customer interest. These limitations result in product damage, theft, or unsatisfactory customer experiences.

[0004] WO2003017806A1 discloses a mobile display unit for street traders is described, which is particularly recommended to contain, conserve, transport and display goods, i.e. objects or foodstuffs in travelling markets. The mobile unit is formed by a structure composed of a base frame from which uprights are detached to which a second frame is attached that forms the upper surface and a third frame placed between the other two frames. The structure accommodates at least one pair of warehouse cases or sliding containers on guides, placed one above the other in the rest mode and side by side in the operative mode.

[0005] US10085552B2 discloses an adjustable rack apparatus that increases the storage, protection, accessibility, security, safety, and organization potential for items packed, for example, utility vehicle beds. The adjustable rack apparatus may be used in conjunction with a storage box that is either fixed to, separate from, or separable from, the adjustable rack. The adjustable rack apparatus comprises a frame, a fixed length rotatable arm, a variable length arm, and an adjustable storage rack. Level substantially vertical movement of the adjustable storage rack is achieved by proper positioning of the fixed length rotatable arms and the variable length arms relative to each other and the frame and the adjustable storage rack. Changing the length of the variable length arm causes movement of the fixed length rotatable arm and level substantially vertical movement of the storage rack.

[0006] Conventionally, many devices have been developed in order to improve the presentation, security, and interactivity of electronic gadgets in retail settings. However, the devices mentioned in the prior arts have limitations pertaining to interactivity, real-time customer engagement features, security mechanisms for high-value items, and dynamic product information.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a device for handling electronic gadgets by facilitating dynamic and personalized information display, ensure secure handling, eye-tracking for interest detection, and real-time inventory updates for providing a more efficient shopping experience.

DETAILED DESCRIPTION OF THE INVENTION

[0018] The following description includes the preferred best mode of one embodiment of the present invention. It will be clear from this description of the invention that the invention is not limited to these illustrated embodiments but that the invention also includes a variety of modifications and embodiments thereto. Therefore, the present description should be seen as illustrative and not limiting.

[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 a retail display device that enables clear product visibility, smooth and quiet access for customers, tailored assistance in selecting products, and safeguards the gadgets from any kind of theft of unauthorized access to maintain product security and prevent misuse.

[0022] Referring to Figure 1, an isometric view of a retail display device is illustrated, comprises of wall-mounted cabinet body 101, multiple individual compartments 102 enclosed by transparent glass panels 103 mounted on the cabinet body, motorized sliding unit 104 integrated within each compartment 102 and connected to the glass panel, a compartment knob 105 installed on each glass panel, a magnetic levitation (MagLev)-based sliding tray arm 106 installed within the compartment, motorized cradle 107 mounted on the tray arm 106, micro-suction surface 108 embedded on the cradle 107, touch-interactive display unit 109 installed on the front of the cabinet body, a transparent OLED screen 110 integrated onto each compartment's glass panel, an UV-C light sanitization module 111 integrated inside each compartment, and a LIDAR-based depth-sensing camera 112 mounted at the top of said cabinet, and a high-tensile flexible fiber leash 113 mechanically connected to an electronic gadgets cradle 107.

[0023] The present invention includes a wall-mounted cabinet body 101 constructed with multiple individual compartments. The body 101 is preferably in portable cuboidal shape incorporating various components associated with the device, developed to be positioned on a ground surface. The body 101 is made up of any material selected from but not limited to metal or alloy that ensures rigidity of the body 101 for longevity of the device. These compartments 102 are configured to securely house individual electronic gadgets while ensuring maximum visibility through the glass enclosure. Each compartment 102 is enclosed by a transparent glass panel 103 that facilitates both aesthetic display and secure containment of the gadgets.

[0024] A user accesses a user interface which is installed in a computing unit linked with a microcontroller inbuilt in the device to wirelessly connect device with computing unit by means of a communication module. The user interface enables the user to provide input regarding activation of the device to assist in displaying the electronic gadgets in a retail outlet. The communication module includes, but not limited to Wi-Fi (Wireless Fidelity) module, Bluetooth module, GSM (Global System for Mobile Communication) module.

[0025] The Wi-Fi module contains transmitters and receivers that use radio frequency signals to transmit data wirelessly to the microcontroller. The wireless module typically includes components such as antennas, amplifiers, and processors to facilitate communication and further connected to networks such as Wi-Fi, Bluetooth, or cellular networks, allowing devices to exchange information over short or long distances for communication of wireless commands to facilitate operations of the device.

[0026] Each compartment 102 integrates a motorized sliding unit 104 to silently and smoothly translate the glass panel 103 upon activation. The motorized sliding unit 104 operates using a linear actuator which provides linear motion to slide the transparent glass panel 103 smoothly. The glass is mounted on sliding unit 104within the compartment, ensuring stable and controlled movement. This is initiated via a compartment-specific knob 105, when engaged, triggers the motor mechanism to grant physical access to the electronic gadget housed inside. When activated via user interaction, the microcontroller sends a signal to the motor controlling sliding unit 104, initiating the panel’s movement.

[0027] Inside each compartment, a motorized telescopic rail is mounted and mechanically linked to a magnetic levitation (MagLev)-based sliding tray arm 106. The telescopic rail is powered by a pneumatic unit that includes an air compressor, air cylinder, air valves and piston which works in collaboration to aid in extension and retraction of the rail.

[0028] The microcontroller sends a signal to the pneumatic unit associated with the telescopic rail that leads to actuation of valve to allow passage of compressed air from the compressor within the cylinder from one end, the compressed air further develops pressure against the piston and results in pushing and extending the piston. The piston is connected with the telescopic rail and due to applied pressure the telescopic rail extends and similarly, the microcontroller retracts the rail by pushing compressed air via the other end of the cylinder, by opening the corresponding valve resulting in retraction of the piston, and the retraction of the rod. Thus, the microcontroller regulates the extension/retraction of the telescopic rail to provide smooth translation to the sliding tray arm 106.

[0029] The sliding tray arm 106 works by embedding opposing magnetic arrays or electromagnets along both the tray arm 106 and the telescopic guide rails, creating a repelling magnetic field that lifts the tray slightly off the surface, effectively eliminating physical friction. A drive coil then provides the propulsion force to move the tray forward or backward with high precision. Upon user activation, the microcontroller energizes the drive coil, causing the tray to glide outward from the cabinet in a stable, silent, and vibration-free manner. Because the tray is suspended magnetically rather than supported by mechanical rollers or bearings, there is no direct surface contact, ensuring long-term durability and smooth operation even under frequent use.

[0030] Mounted on the tray arm 106 is a motorized cradle 107 that holds the electronic gadget at a predefined viewing angle to securely hold an electronic gadget. The cradle 107 incorporates a micro- suction surface 108, which provides a reversible, secure grip on the gadget without leaving adhesive residue or causing surface damage.

[0031] A spherical joint is integrated with the motorized cradle to rotate the cradle at an ergonomic viewing angle to hold the electronic gadget. The spherical joint consists of a ball-and-socket arrangement where the cradle is connected to a ball mounted within a socket. The motorized arrangement, controlled by a microcontroller, actuates this joint to rotate the cradle smoothly to the desired orientation.

[0032] The micro- suction surface 108, is made from a specialized polymer sheet embedded with microscopic suction structures that are tiny cups that are invisible to the naked eye. When the surface of the cradle 107 is gently pressed against the back of a smooth electronic gadget, the micro-suction cups expel air and form a weak vacuum, generating a firm, reversible grip through atmospheric pressure. This adhesion is strong enough to hold the device securely in place during interaction but easily released without applying excessive force.

[0033] The cabinet body 101 is installed with a touch-interactive display unit 109 to facilitate digital interaction with users. Through this display unit 109, user that are customers in the retail outlet are able to search for electronic gadgets stored within the cabinet, initiate a product comparison, and access multimedia content. The display unit 109 functions by allowing users to interact directly with the display unit 109 through touch input. The display unit 109 is typically made up of a display and a touch-sensitive layer. The touch-sensitive layer uses capacitive or resistive technology to detect touch by the user, which then sends signals to the panel’s processor. Once the display panel 103 detects touch, sends a signal to the microcontroller that processes the input to provide associated output.

[0034] Upon starting a search, users are also able to apply a variety of practical filters to refine their results based on personal preferences and needs. These filters include selecting a preferred brand, setting a budget range, and specifying key features such as camera quality (e.g., 50MP+, night mode), battery capacity (e.g., 4000mAh+ with fast charging), screen size, RAM, and processor type. Customers are able to filter phones based on specific use cases like gaming, photography, business, or senior-friendly designs. Additional options let users choose the operating system, connectivity features such as 5G or dual SIM support, and whether they are looking for the latest models or phones eligible for trade-in. To improve accessibility, the interface offers voice-to-text input, a “Help Me Choose” assistant, and image-based search functionality. Once preferences are submitted, the display unit 109 displays matching phones, allowing customers to compare models side-by-side, view 360° demos, interact with physical units via motorized trays, and save or share results using a QR code.

[0035] The display unit 109 enables users to compare selected models side-by-side, view 360-degree demos of each electronic gadget, interact with said electronic gadgets via coordinated activation of compartment, and save or export selected results using a QR code displayed over the display unit 109.

[0036] The microcontroller is operatively connected to a transparent OLED (Organic Light Emitting Diode) screen 110 integrated into each compartment 102 and is also linked to an inventory database that stores detailed information about all available electronic gadgets. When a customer interacts with a specific compartment, the microcontroller retrieves relevant data from the inventory database corresponding to the selected device. This data includes comprehensive product specifications such as brand, model, technical features (e.g., camera resolution, processor, RAM, battery life), pricing details, current promotional offers, and verified customer reviews.

[0037] At the top of the cabinet, a LIDAR-based depth-sensing camera 112 is mounted that operates in tandem with a gesture recognition protocol to interpret predefined hand gestures. The LIDAR-based depth-sensing camera 112 operates by emitting rapid pulses of infrared laser light into the surrounding space. These laser beams bounce off surfaces such as a customer’s hand performing a gesture and return to the camera’s 112 sensor. By calculating the time taken for each pulse to return (known as time-of-flight), the camera 112 constructs a highly accurate 3D depth map of the environment in real time. This depth data is continuously analysed using a gesture recognition protocol, which has been trained to identify specific hand movements or positions. When a recognized gesture indicating access intent is detected, the microcontroller responds by unlocking and sliding open the corresponding compartment 102 glass panel.

[0038] To enhance security, each electronic gadget cradle 107 is connected to a high-tensile flexible fiber leash 113, which incorporates a sensing module. The sensing module is capable of detecting abnormal tension or rapid pulling movements indicative of tampering or unauthorized handling. The sensing module includes a tension sensor and an accelerometer.

[0039] The tension sensor embedded in the high-tensile flexible fiber leash 113 is designed to monitor the amount of strain being applied along the leash 113. It typically consists of a strain gauge that detects changes in resistance when the leash 113 is stretched beyond its normal operating range. Under standard handling conditions, the tension remains within predefined safe limits. However, if a user attempts to pull the gadget forcefully or tamper with it, the increased tension is detected by the sensor, which generates an electrical signal proportional to the applied force. This signal is sent to the microcontroller, which interprets the abnormal tension as a potential security threat.

[0040] The accelerometer in the sensing module detects sudden movements or changes in motion, such as rapid pulling, shaking, or jerking of the cradle 107 or the connected device. It works by measuring acceleration forces along one or more axes (typically X, Y, and Z) using tiny microelectromechanical components (MEMS). When the leash 113 experiences motion that exceeds normal interaction thresholds, especially abrupt directional changes, the accelerometer registers the movement and sends this data to the microcontroller that compares the signal to a pre-defined database. Upon detecting such tension conditions, the microcontroller immediately initiates rapid retraction of the tray arm 106 back into the cabinet, and simultaneously actuation of the sliding … to slide the panel in a manner to close the compartment, thereby securing the device. The microcontroller transmits a security notification to at least one external computing unit, including a store manager’s computing unit, on-site control panel, or remote security unit, in response to said detection events.

[0041] An optical gaze detection unit is embedded in each compartment 102 of the cabinet structure to assess customer interest. This detection unit includes a high-resolution 3D optical sensor array coupled with an infrared gaze-tracking camera 112, which jointly monitor eye movement and facial orientation. Each compartment 102 features a transparent OLED screen 110 that overlays dynamic digital content directly onto the transparent glass, allowing the detection unit to tailor product information based on inferred user interest.

[0042] The high-resolution 3D optical sensor array captures detailed three-dimensional data of the user's face and surrounding environment by projecting structured light. This array consists of multiple image sensors that work together to generate a depth map by calculating the distance between various facial features and the cabinet. The depth data enables the microcontroller to determine the position and orientation of the user's head with high accuracy.

[0043] The infrared gaze-tracking camera works by emitting low-intensity infrared light toward the user’s eyes and capturing the reflected IR patterns using a sensitive camera lens. The camera tracks the position of the pupil and corneal reflection, which shift as the eyes move. By continuously analyzing these changes, the camera determines the direction of the user’s gaze in real time to determine exactly where on the screen 110 or inside the compartment 102 the person is looking.

[0044] Based on the detected user’s interest by the detection unit, the microcontroller is configured to render dynamic, contextual visual content directly onto the transparent OLED screen 110 in front of the selected gadget. This includes interactive 3D visualizations, allowing customers to explore the gadget from multiple angles in real-time. The integration of real-time data retrieval with high-resolution display ensures an informative, immersive, and engaging product discovery experience, all facilitated through the seamless coordination between the microcontroller, OLED screen 110, and database.

[0045] A LIDAR sensor embedded on the cabinet body 101 to scan and detect electronic gadgets held by customers within a predefined proximity of the cabinet. Using images captured by the camera 112, the microcontroller extracts visual identifiers such as brand logos, design outlines, camera configurations, or body 101 geometry to identify the gadget in real-time.

[0046] The LIDAR sensor operates by emitting rapid pulses of laser light across the space in front of the cabinet and measuring the time it takes for each pulse to bounce back after hitting nearby objects. By collecting thousands of these measurements per second, the sensor creates a real-time 3D map of the area, allowing it to detect when a customer is holding the gadget, within a specific detection range. Once the gadget is detected, the microcontroller uses a connected camera 112 to capture high-resolution images of the gadgets.

[0047] The microcontroller then processes these images to extract visual identifiers such as brand logos, design outlines, camera placement, screen 110 shape, or body 101 geometry. This information is compared against an internal database to identify the gadget in real-time, enabling the microcontroller to display relevant product comparisons, upgrade options, or promotional offers on the nearby display or OLED screen 110s.

[0048] Upon successful identification, the microcontroller infers the brand, model, technical tier, estimated market price, release year, and comparative ranking of the detected device. This information is then presented on the display unit 109, assisting customers in evaluating their current gadget against available alternatives. With user consent, the microcontroller also recommends a plurality of alternative electronic gadgets with similar or superior specifications within the same or nearby price tier, helping the customer make an informed purchase decision.

[0049] At the rear wall of the cabinet lies a track grid comprising a network of motorized horizontal and vertical slider rails. These rails enable internal repositioning of gadget trays. The track grid is composed of horizontal and vertical rails mounted along the rear wall of the cabinet, forming a two-dimensional movement plane. Each gadget tray is mounted on a carriage that is connected to both sets of rails. Electric motors are integrated into the rails and controlled by the microcontroller, allowing for synchronized movement in either direction.

[0050] When a customer interacts with the device, such as selecting a product via the screen 110 or being identified through gaze detection, the microcontroller calculates the tray’s target position and activates the corresponding motors. The horizontal rail moves the tray carriage laterally, while the vertical rail moves it up or down, allowing the tray to be precisely repositioned to the desired location. Based on input from the gaze detection unit or physical user interactions, the microcontroller controls the movement of trays to align selected electronic gadgets with the user's eye level for optimal visibility.

[0051] To ensure hygiene and safety, each compartment 102 is integrated with a sanitization module 111 that activates a timed UV-C light cycle after each customer interaction as detected by the sensing camera 112. This disinfection process sterilizes the surface of the gadget, minimizing the risk of microbial transmission. UV-C light operates at a wavelength between 200–280 nanometers, which is effective in destroying the genetic material of microorganisms.

[0052] The sanitization module 111 consists of UV-C LED lamps strategically positioned within the compartment 102 to ensure even exposure of the gadget's surface. Once activated, the module maintains illumination for a predefined duration, typically a few seconds to a few minutes, to achieve sterilization without damaging the device.

[0053] A battery (not shown in figure) is associated with the device to supply power to electrically powered components which are employed herein. The battery is comprised of a pair of electrodes named as a cathode and an anode. The battery uses a chemical reaction of oxidation/reduction to do work on charge and produce a voltage between their anode and cathode and thus produces electrical energy that is used to do work in the device.

[0054] The present invention works best in the following manner, where the present invention includes a wall-mounted cabinet body 101 equipped with multiple transparent compartments, each showcasing a different electronic gadget under transparent OLED screen 110. The transparent screen 110 display dynamic product information, promotional visuals, and interactive cues based on real-time analysis of customer gaze via the integrated optical gaze detection unit. When a customer lingers visually on a particular device, the gaze detection unit identifies interest and the microcontroller triggers the OLED to enhance content display with richer visual overlays such as 3D models or promotional videos. The user interact with the touch-interactive display unit 109 to filter and search for specific devices based on brand, specifications, price, or customer reviews. The LIDAR-based depth sensing camera 112 detects the user’s hand gesture and upon successful validation, the motorized sliding unit 104 quietly opens the glass panel 103 of the relevant compartment. Simultaneously, a MagLev-based sliding tray arm 106, mounted on a telescopic rail, extends outward with near-zero friction and sound.

[0055] In continuation, the motorized cradle 107 on the tray, inclined at an ergonomic viewing angle and equipped with a micro- suction surface 108, presents the device securely and cleanly for user interaction. Throughout this process, a flexible fiber leash 113 connected to the cradle 107 ensures theft prevention. This leash 113 includes a sensing module with tension and motion detection capabilities (such as accelerometers), which continuously monitors for unauthorized force or tampering. If abnormal tension or movement is detected, the microcontroller sends signal to instantly retract the tray and locks the compartment, while simultaneously transmitting a security notification to a store manager, on-site console, or remote monitoring unit. The LIDAR and camera 112 scan the object, extract identifiable visual features, and match them against a database to infer the model, tier, release year, and estimated market value. Upon user consent, the display unit 109 presents a comparison chart and suggests alternative or upgraded devices with better specifications or value, enabling informed decision-making. After each customer interaction, an automated sanitization cycle is triggered, activating the UV-C light module within the compartment 102 to disinfect the device before it is presented again.
