Description:FIELD OF THE INVENTION

[0001] The present invention relates to a perfume showcasing and testing device that is capable of facilitating an interactive and engaging experience for users, allowing efficient presentation, evaluation, and personalized selection of perfumes in a controlled and user-friendly manner.

BACKGROUND OF THE INVENTION

[0002] In the fragrance industry, showcasing and testing perfumes plays a vital role in influencing consumer choices and enhancing brand engagement. As markets grow more competitive and customer preferences become increasingly personalized, there is a strong demand for innovative methods that offer immersive, efficient, and appealing presentation of perfume products. Conventional perfume display units often lack the ability to attract user attention or provide personalized testing experiences, which results in missed sales opportunities or user disengagement. Moreover, the evaluation of a perfume's suitability often relies solely on direct human interaction or limited manual sampling, which is inconsistent, time-consuming, and less hygienic in high-traffic environments. Retailers and brands require a solution that not only attracts potential users but also creates a lasting sensory impression while accommodating diverse user needs and preferences.

[0003] Traditionally, perfume testing has relied on manual spray bottles, sample cards, and in-person demonstrations by store personnel. While these methods offer basic interaction, they do not account for individual scent preferences, user reactions, or environmental factors that influence fragrance perception. In addition, traditional display arrangements are often static and non-interactive, limiting engagement and offering little data on user behaviour or preferences. As consumer expectations shift toward personalized and technology-enhanced experiences, the existing methods fall short of delivering a comprehensive solution.

[0004] WO2021224379A1 discloses a fragrance testing device comprising a housing (1; 1'; 101) defining an enclosed space for receiving a bottle (6) having an outlet port, a reservoir for containing fragrance and a system for spraying at least one measured amount of fragrance comprising means constituting a pump (7, 30) placed in or above the outlet port of the bottle (6) and capable of pumping a test amount of perfume from the bottle, a nozzle (11) capable of spraying the perfume pumped by the pumping means, and actuating means capable of actuating the pump, characterised in that the device further comprises means constituting a sensor (5) capable of detecting the presence of at least part of the body of a person near a front face of the housing, the actuating means being capable, under the control of the information received from the presence detection means, of applying a pressure to the pump so that it draws off a measured amount of fragrance for delivery by the nozzle (11), the nozzle having an end opening outside the front face of the housing and being offset relative to the bottle.

[0005] US11156533B2 discloses an invention relates to a system for testing a perfume, comprising a housing, a test member able to be at least partially inserted into the housing so as to be impregnated with the perfume, a dispensing device for dispensing the perfume on the test member, a sensor for detecting the presence of the test member, an actuator for actuating the dispensing device, and a processing unit which controls the actuator in order to trigger the dispensing during extraction of the test member.

[0006] Conventionally, many devices are used for perfume showcasing and testing, but these devices offer limited interaction and rely heavily on manual processes. These setups often fail to capture user preferences or adapt to individual choices, resulting in a generic and impersonal experience. They are typically designed for basic presentation and do not engage users in a meaningful or customized manner, leading to reduced interest, lower retention, and missed opportunities in user engagement and product selection.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a device that requires to provide an engaging, personalized, and interactive experience for users while showcasing and testing perfumes. Such a device should also be capable of capturing user interest, adapting to individual preferences, and offering an enhanced sensory interaction that improves product evaluation and selection, thereby creating a more effective and memorable perfume showcasing environment.

[0022] Referring to Figure 1 and 2, an isometric view of a perfume showcasing and testing device and an inner view of a perfume testing module associated with the device are illustrated, respectively, comprising a mobile housing 101, a plurality of telescopic rods 102 are provided underneath the housing 101, each of the rods 102 provided with an omnidirectional wheels 103, a plurality of rollers 104 installed over the housing 101 by means of sliding units 105, each of the roller 104 containing a pliable display panel 106, the rollers 104 are connected with the sliding unit 105 by means of finger coupler 107 mounted with a scissor arrangement 108 by means of an angular rod 109, the finger coupler 107 comprises a pair of opposing discs 110 constructed with a plurality of fingers 111 projecting along the mating surfaces, the discs 110 connected with a hinged frame 112, a plurality of RGB (Red, Green, Blue) lightening elements 113 installed over the housing 101 in an articulated manner by means of ball and socket joints 114, a perfume testing module 201 installed with the housing 101 comprises a multi-section chamber 201a crafted within the housing 101 stores with test strips, a holder 201b provided with each of the chamber 201a containing a perfume bottle, a presser 201c provided at an upper portion of the holder 201b.

[0023] Figure 1 and 2 further illustrates an articulated telescopic gripper 201d attached within each of section of the chamber 201a, the presser 201c comprises a frame 202 provided with a spring–loaded guided bar 203 translated by a rack and pinion arrangement 204 provided with the frame 202, a camera 115 mounted on the housing 101, a touch enabled display unit 116 installed on the housing 101, a plurality of dispenser 205 integrated with the housing 101, each connected via an opening 206 formed at a front portion of the housing 101, the dispenser 205 comprises a plurality of elongated compartments 207 arranged within the housing 101 and a rotatable spiral structure 208, a microphone 117 installed with the housing 101, an opening 118 to access test strip by a user.

[0024] The device disclosed herein comprises of a mobile housing 101 mounted over a plurality of telescopic rods 102, constructed from a lightweight, high-strength polymer composite to ensure durability and ease of transport. The housing 101 is preferably cuboidal in shape, providing structural stability. Internal compartment of the housing 101 is arranged to securely accommodate all mechanical and electronic components, with a reinforced base to maintain balance and absorb vibration during locomotion.

[0025] The plurality of telescopic rods 102 is provided underneath the housing 101 in order to extend or retract the housing 101 height, each of the rods 102 provided with omnidirectional wheel at bottom end for locomotion of the housing 101. The telescopic rods 102 operated by a pneumatic unit function through a series of interlocking cylindrical segments that extend or retract based on air pressure. Internally, each rod 102 is connected to a pneumatic actuator supplied by a compressed air reservoir controlled by solenoid valves. When a microcontroller sends a signal, the solenoid valve opens, allowing pressurized air to enter the rods 102 chamber, forcing the segments to extend. To retract, the air is released or redirected, allowing the segments to collapse smoothly. Internal guides and seals ensure alignment and prevent air leakage, enabling stable, adjustable height control of the housing 101.

[0026] The omnidirectional wheels 103 operate using a central hub fitted with a series of angled rollers mounted around its circumference. These rollers are positioned at 45 or 90 degrees to the wheel’s rotation axis, allowing movement in multiple directions. When the wheel rotates normally, it moves forward or backward, while the angled rollers enable sideways or diagonal sliding without turning the wheel. Each wheel is driven by a dedicated motor, and precise movement is achieved through coordinated control of all wheel motors.

[0027] A plurality of rollers 104 installed over the housing 101 by means of sliding units 105, each of the rollers 104 containing a pliable display panel 106 for displaying showcase material for perfumes inputted by a supervisor. The plurality of rollers 104 are rotatable cylindrical structures mounted on the housing 101 via sliding units 105, allowing horizontal adjustment along a track. Each roller is internally supported by bearings and driven by a miniature motor, enabling smooth rotation. The rollers 104 are connected to an angular support means that allows tilt or orientation adjustment, enhancing visibility. These rollers 104 serve as mounting frames for the pliable display panels 106, enabling dynamic showcasing of visual content and advertisements.

[0028] The pliable display panel 106 is a flexible e-paper-based screen that wraps around the roller's surface. Internally, the display contains thin-film transistors layered over a flexible substrate, allowing it to bend with the roller without damaging circuitry. The display receives digital content via a dedicated driver circuit, controlled by a central processing unit. A low-voltage power supply integrated within the roller powers the panel. The surface is coated with an anti-glare, scratch-resistant layer for clarity and durability. This structure enables real-time display of advertisements or multimedia content in varying orientations.

[0029] The sliding units 105 internally constructed with a rail and carriage mean, where the carriage is mounted to the base of each roller and guided along a linear track fixed on the housing 101. Movement is facilitated by an internal micro motor coupled with a lead screw that translates rotational motion into linear displacement. Limit sensors to define travel range and ensure precise positioning. This allows each roller to slid horizontally for optimized display orientation.

[0030] A user interface adapted to be installed with a computing unit to connect with a communication module of the housing 101 to upload showcasing material to be displayed. The user interface functions through a touch-enabled panel connected to the internal computing unit. The user interface consists a custom interface application that allows the supervisor to upload and manage perfume showcasing content. The interface communicates with the housing’s internal communication module to synchronize data with connected modules. It processes inputs using an input detection circuit, and displays real-time status, suggestions, or updates. This setup enables seamless content control via mobile, tablet, or laptop, scheduling, and interaction within the perfume showcasing device.

[0031] Each of the rollers 104 is connected with the sliding units 105 by means of finger coupler 107 for precise alignment of the roller. The finger coupler 107 comprises a pair of opposing discs 110, each of the discs 110 constructed with a plurality of fingers 111 projecting along the mating surfaces to enable an interlocking of the discs 110. The discs 110 connected with a hinged frame 112 to enable a rotation of the rollers 104 in different orientations. The opposing discs 110 operate as core rotational elements that align against each other, with each disc 110 featuring the plurality of fingers 111 arranged radially along its surface. These fingers 111 are designed to interlock with the corresponding fingers 111 on the opposite disc 110 when pressed together, creating a friction-based coupling.

[0032] This interlocking structure enables firm positional holding while still allowing manual rotation. The internal tension or pressure between the discs 110 determines the resistance during adjustment, providing secure yet adjustable movement of the attached rollers 104. And the hinged frame 112 connects both opposing discs 110 and offers a pivotal axis for multidirectional articulation. Internally, the frame 112 integrates pivot pins that allow the mounted discs 110 to swing or rotate along different planes. This hinge-based connection enables dynamic angling or tilting of the roller assembly to suit various user interactions or display orientations.

[0033] All these arrangements are mounted with a scissor arrangement 108 by means of an angular rod 109 to facilitate an adjustable orientation of the roller. The scissor arrangement 108 integrated vertically over the sliding units 105 and connects a central pivot pin to the angular rod 109. Each angular rod 109 is joined by a central pivot pin, enabling them to slide past each other when force is applied along the ends. As the rods 109 expand outward, the height or span of the structure increases proportionally; when compressed, the structure collapses inward in a uniform, parallel motion. This allows for smooth vertical or horizontal translation while maintaining balance and structural integrity. Springs or guided slots may be used at joints to assist with synchronized motion and load distribution.

[0034] A plurality of RGB (Red, Blue, Green) lighting elements 113 installed over the housing 101 in an articulated manner to provided illumination to the advertisements. The RGB lighting elements 113 work internally using a combination of red, green, and blue light-emitting diodes (LEDs) embedded within a compact housing 101. Each LED is controlled by the microcontroller that adjusts voltage levels to vary the brightness of each colour. By blending the intensities of red, green, and blue, it generates a full spectrum of colours. The lighting behaviour, including brightness and hue shifts, dynamically controlled based on ambient sensor input or user interface settings, enabling responsive and adaptive illumination.

[0035] Furthermore, the lightning elements 113 are attached with the housing 101 by means of ball and socket joints 114. The motorized ball and socket joint works internally by integrating a spherical ball within a concave socket, allowing multi-directional movement. Miniature motors embedded in the socket are connected to the ball via linkages. When electrical signals are sent to the motors from the microcontroller, the motors adjust the angle and orientation of the ball with precision. Encoder sensor track movement and provide real-time feedback, allowing to maintain or dynamically adjust positioning. This configuration enables smooth, controlled articulation in multiple axes for adaptive and responsive movement of lightning elements 113 for illumination.

[0036] An LDR (Light Dependent Resistor) integrated over the housing 101 to detect an instant ambient brightness to cause a regulation of the lighting elements 113 accordingly. The LDR works internally based on the principle of photoconductivity. It is made from a high-resistance semiconductor material, typically cadmium sulphide (CdS). In darkness or low light, the resistance of the LDR is very high, restricting current flow. When light falls on its surface, photons energize electrons in the material, reducing resistance and allowing more current to pass. The resistance changes in proportion to light intensity. This behaviour is detected by the microcontroller, which uses the varying electrical signal to trigger actions like adjusting lighting or displays.

[0037] Additionally, a weather module configured with the control unit to fetch weather forecast via the communication unit and accordingly suggest the supervisor by the user interface regarding repositioning the housing 101 and scheduling the showcasing for safe operation of the housing 101. The weather module works by integrating environmental sensors such as temperature, humidity, and barometric pressure sensors with a wireless communication unit. These sensors collect real-time local weather data, while the communication unit fetches external weather forecasts from online sources. The collected data is processed by the microcontroller, which detects unfavorable conditions like rain, wind, or poor visibility. Based on this analysis, the microcontroller sends alerts to users, suggests alternate display times, or automatically adjusts brightness, volume, or content for optimal ad performance.

[0038] When the user selects an area to display the advertisement, on the same time if the microcontroller receives an alert signal from the weather module about bad weather conditions, the weather module notify the user via the computing unit to postpone the plan due to unfavorable weather and also suggest an alternative date to display the advertisement. While the user uploads their advertisement content through the computing unit, it will analyze the details and suggest suitable locations based on the content preferences uploaded by the supervisor through the user interface.

[0039] A perfume testing module 201 installed with housing 101 to facilitate the users to test perfumes. The perfume testing module 201 comprises a multi-section chamber 201a crafted within the housing 101 and each stored with tested strips for testing perfumes. A holder 201b provided in each of the sections of the chamber 201a containing a perfume bottle. The chamber 201a is typically made of lightweight, durable materials such as ABS plastic or polycarbonate for strength and chemical resistance. The holder 201b, also made of similar non-reactive materials, features divided sections shaped to securely fit each sample. Internally, each section is aligned with dispensing units, ensuring accurate placement, easy access, and hygienic operation during showcasing or testing.

[0040] Furthermore, a presser 201c provided at an upper portion of the holder 201b to press a sprayer of the perfume bottle to spray perfume onto test strip for testing. The presser 201c comprises a frame 202 provided with a spring-loaded guided bar 203 translated by a rack and pinion arrangement 204 provided with the frame 202. The spring-loaded guided bar 203 comprises a linear bar 203 housed within a guided channel, where precision compression springs are mounted at one or both ends. When the bar 203 is actuated by the microcontroller, the spring compresses and stores mechanical energy, allowing controlled motion along the guide. Upon release, the spring returns the bar 203 to its original position, ensuring consistent alignment.

[0041] Within the presser 201c, the rack and pinion arrangement 204 functions to convert rotational motion into precise linear motion for pressing actions. The pinion is a circular gear connected to a motor or manual actuator, while the rack is a flat, toothed bar positioned in alignment with the pinion. When the pinion rotates, its teeth engage with the rack’s teeth, driving the rack linearly either upward or downward, depending on the rotation direction. This controlled linear movement allows the presser 201c to apply uniform pressure on the target sprayer.

[0042] The test strip extended by an articulated telescopic gripper 201d attached within each section of the chamber 201a. The telescopic gripper 201d operated by a pneumatic unit works by utilizing compressed air to extend and retract gripping arms. The gripper 201d consists of nested telescopic segments that slide within one another, guided by a sealed cylindrical housing 101. A pneumatic actuator supplies pressurized air into specific chambers within the housing 101, creating a force that pushes the inner segments outward to extend the gripper 201d. Releasing or redirecting the air causes retraction. At the end of the telescopic arms, gripping jaws close or open based on secondary pneumatic signals, allowing secure and adjustable holding of perfume strips, wherein the microcontroller then actuates the pneumatic valves based on input signals to control the timing, direction, and pressure of the airflow, thereby enabling precise extension, retraction, and gripping actions in response to user commands.

[0043] After the perfume is sprayed on the strip, the telescopic gripper 201d moves the strip outward through an opening 118 formed in the housing 101 for user access. Then, to capture facial data of users and determine facial expressions and physical gestures of the users while viewing the advertisements and testing perfumes, a camera 115 is mounted on the hosing integrated with a process in synchronization with an infrared sensor and configured with a facial recognition module to gauge reaction of the users. The camera 115 works by capturing visual data from the surrounding environment or user interactions through a lens assembly that focuses incoming light onto an image sensor such as a CMOS (Complementary Metal-Oxide-Semiconductor) or CCD (Charge-Coupled Device). The sensor converts the light into electrical signals, which are then digitized and processed by an onboard image processor. The processed image is transmitted to the microcontroller, which analyzes facial expressions, gestures, or alignment cues to guide functions like ad optimization, user interaction, or targeted perfume strip dispensing based on engagement.

[0044] The infrared (IR) sensor operates by emitting infrared light through an LED (Light Emitting Diode) and detecting the reflected rays using a photodiode. When the user or object comes within range, the reflected IR signal changes in intensity, which is sensed and converted into an electrical signal. This signal is sent to the microcontroller, which interprets proximity, hand gestures, or movement patterns. The sensor enables touchless interactions for hygiene and convenience, such as activating strip dispensing or illuminating displays in response to user presence.

[0045] A determination module configured with a control unit receives data from the camera 115 and the infrared sensor to determine a positive and negative reaction of the users to perfumes and accordingly initiate testing of one or more perfumes. The determination module functions as an intelligent processing unit integrated with the microcontroller. The determination module receives input data from various sensors, including the camera 115, infrared sensor, facial expression analyser, and environmental modules. The module analyses this data using embedded protocols to assess user preferences, emotional responses, environmental conditions, or scent compatibility. Based on this analysis, it determines suitable actions such as which perfume to suggest, whether to activate a lighting mode, or whether to delay advertisement display. It enables adaptive decision-making by continuously learning and refining its responses through feedback and historical interaction data.

[0046] To display details of the perfume preferred by the user, a touch enabled display unit 116 mounted on the housing 101. The touch-enabled display unit 116 works by integrating a capacitive touchscreen with a digital display panel. When the user touches the screen, the electrical charge at the contact point changes, allowing the touch controller to detect the exact location of the touch. This signal is then processed by the microcontroller, which interprets the user's input such as selecting a perfume, viewing scent data, or navigating the interface and updates the display accordingly, enabling real-time interactive control over the device’s operations.

[0047] In order to display questions to the user via the display unit 116, a questionnaire module configure with the control unit to determine user’s responses based on their answers on the questions. The questionnaire module operates through a user-interface displayed on the display unit 116. The user responds to a series of curated questions designed to evaluate preferences, emotional tone, lifestyle, and sensory inclinations. These responses are collected and processed by the microcontroller, which then transmits the data to an AI (artificial intelligence)-driven protocols. The protocols classify personality traits using psychometric analysis models and maps the results to a preloaded scent profile database. Based on this analysis, the module recommends a perfume that best aligns with the user's identified traits and sensory preferences, offering a personalized fragrance experience.

[0048] An e-nose integrated in the housing 101 to capture fragrance of perfume combined with user’s natural scent to determine a suitability of the perfume for the user. The e-nose functions by using an array of gas sensors that detect volatile organic compounds (VOCs) emitted by perfume samples. When the perfume is sprayed, the scent molecules enter the e-nose chamber, where each sensor responds to specific chemical signatures by altering its electrical resistance. These sensor responses are then converted into digital signals and analyzed by the microcontroller. The data is compared against a stored scent profile database, enabling the e-nose to identify or categorize the perfume's fragrance characteristics accurately.

[0049] The data from the e-nose and response of the users from the questionnaire module received by a selection module configured with the control unit to determine the most suitable perfume for the user. The selection module configured with the control unit assists in determining the most suitable perfume by analyzing user inputs received through various interactive components such as the questionnaire module, e-nose analysis, and facial expression recognition. The selection module processes this input data and sends it to the control unit, where advanced protocols evaluate user preferences, emotional responses, and olfactory compatibility. Based on the evaluation, the control unit ranks various perfume options and identifies the most appropriate one. This output enables presentation of a tailored perfume recommendation on the display unit 116 that aligns with the user’s preferences, sensory profile, and real-time interaction data.

[0050] After selection of a perfume best suitable for the user, the microcontroller actuates a dispenser 205 integrated with the housing 101 to store various perfume products and dispense the selected perfume via an opening 206 formed at a frontal portion of the housing 101. The dispenser 205 comprises a plurality of elongated compartments 207 arranged within the housing 101, a rotatable spiral structure 208 containing perfume products, the structure being rotated to cause the perfume product to move towards the opening 206.

[0051] The dispenser 205 operates by utilizing a motor-driven actuation means that engages with the rotatable spiral structure 208, which is configured to hold and support multiple perfume containers in its elongated compartments 207. Upon receiving a signal from the microcontroller, the motor initiates rotation of the spiral structure 208, causing the selected perfume container to gradually advance along the helical path toward the frontal opening 206. A guiding rail ensures the perfume container maintains alignment during movement. Once the selected perfume container reaches the dispensing position, and the user gets if from the frontal opening 206, sensors positioned near the opening 206 detect the completion of dispensation, upon which the dispenser 205 halts the rotation and repositions the spiral structure 208 for the next operation cycle.

[0052] After the selected perfume is dispensed through the opening 206, the microcontroller initiates the generation of a corresponding QR (Quick response) code linked to that specific perfume product. The QR code is displayed via the display unit 116 to enable the user to make a payment for perfume to be purchased. The control unit retrieves relevant information such as product name, ingredients, brand, price, and purchasing link from the connected database from the microcontroller. This data is encoded into the dynamic QR code, which is then visually rendered on the touch-enabled display unit 116. The display unit 116 uses integrated graphics processing to ensure the QR code is clear and scan able. This allows the user to scan the code using a mobile device for instant purchase or to access additional product details.

[0053] Additionally, a microphone 117 installed with the housing 101 to receive vocal responses from the user to determine a language preferred by the user to accordingly shows content displayed via the display unit 116 to follow the preferred language. The microphone 117 comprises a diaphragm that vibrates upon receiving sound waves generated by the user’s voice. These vibrations are converted into electrical signals through changes in magnetic fields. The signals are routed to an analog-to-digital converter (ADC), which digitizes the input for further processing. The digital voice data is then transmitted to the microcontroller, where embedded voice recognition protocols analyse the phonetic patterns to identify the spoken language. Based on the determined language, the microcontroller updates the display unit 116 to present content in the user’s preferred language, enhancing interaction and accessibility.

[0054] Lastly, 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.

[0055] The present invention works best in the following manner, where the mobile housing 101 as disclosed in the invention is positioned by the supervisor in a desired area for perfume showcasing. The telescopic rods 102 provided underneath the housing 101 are operated by the pneumatic unit to adjust the height, and the omnidirectional wheels 103 allow the housing 101 to move smoothly across various surfaces. The sliding units 105 mounted on the housing 101 enable the plurality of rollers 104 to be adjusted horizontally, while the angular rod 109 allows the rollers 104 to be tilted for optimized visibility. Each roller, driven by an internal motor, rotates to display dynamic multimedia content through the pliable display panels 106 wrapped around them. The pliable display panels 106 receive perfume-related content inputted by the supervisor via the user interface, and showcase it in real-time. The RGB lighting elements 113, regulated by feedback from the LDR, adjust illumination based on ambient brightness. The weather module communicates environmental data to the control unit, which alerts the supervisor via the user interface to reposition the housing 101 or reschedule the showcasing as needed.

[0056] In continuation, the perfume testing module 201 allows the user to test various perfumes using articulated telescopic gripper 201d that extend test strips from respective sections, where the presser 201c, actuated by a spring-loaded guided bar 203 with rack and pinion arrangement 204, sprays perfume onto the strip, after that the gripper 201d move the strips towards the opening which exactly at the front of perfume testing module 201 on the housing 101. The camera 115 mounted on the housing 101, in synchronization with the infrared sensor, captures facial expressions and gestures, and transmits data to the facial recognition and determination modules to assess user reactions. Based on the positive or negative response, the device initiates further testing. The questionnaire module displayed on the touch screen collects user preferences, while the e-nose analyzes the scent compatibility between perfume and the user’s natural body odor. The selection module processes all inputs to suggest the most suitable perfume. The dispenser 205 rotates an internal spiral structure 208 to deliver the selected product through an opening 206, and a QR code is generated on the display for the user to make payment.
