Description:FIELD OF THE INVENTION

[0001] The present invention relates to a grocery shopping assistive device that provides a trolley-shaped dual storage space to a user for accommodating various dry and cold grocery items separately during grocery shopping and also guides the user to the precise location of the grocery items within the store by accessing the shopping list of grocery items to be purchased.

BACKGROUND OF THE INVENTION

[0002] Grocery shopping is a routine activity for individuals and families, that involves purchasing a mix of perishable items like fruits, vegetables, dairy, and meat, alongside non-perishable goods such as cereals, canned foods, and cleaning supplies. Shoppers often rely on labels for expiration dates, but oversight or unclear labeling lead to the selection of expired or nearly expired items, posing health risks and causing waste. Locating specific items in large stores or marts is also challenging due to extensive layouts and frequent reorganization of shelves. This process becomes more time-consuming without clear directions, particularly when searching for specific brands or products listed on a shopping list.

[0003] Traditionally, people use basic trolleys or hand basket for grocery shopping. Shoppers often have a physical shopping list to track their items, navigating the store's sections like produce, dairy, and canned goods. To find specific items, they either search the aisles by product category or rely on store signage. Checking for expiry dates involves inspecting product labels or packaging manually. Traditional trolleys lack features to segregate items based on storage requirements or to assist in navigation within a store. Traditionally, shoppers manually locate items and track offers, which is time-consuming and inefficient. Another concern is the inadvertent selection of expired or near-expired items, which lead to wastage and health risks. Thus, there is a need to develop a device that improve the overall shopping experience.

[0004] US20130334780A1 discloses about a shopping trolley which is stackable with similar trolleys, having a chassis, having a holding unit which is connected to the chassis, and having a pushing unit located at the rear, wherein the chassis has two curved longitudinal supports leading from the rear side castors to the front side castors of the shopping trolley. The two longitudinal supports, proceeding from their rear end section, extend upward and toward the front and subsequently, inclined downward toward the front, are continued to the front end section such that at least the intermediate section, or the intermediate section and the end section, of each longitudinal support belongs to either of two geometrical planes which, proceeding from the plane of travel of the castors, extend from bottom to top. The invention is characterized in that the front end sections are led out of the planes extending from bottom to top. Although, US’780 discloses about an invention that relates to a shopping trolley. However, the cited invention lacks in providing a separate storage space for accommodating various dry and cold grocery items.

[0005] US20070063465A1 discloses about a basket for a shopping cart comprising a single unitary member molded from a plastic material. The basket includes a frame including a plurality of generally vertical upright frame members spaced apart from each other, with each frame member including a generally smooth outer surface without holes. A front panel extends generally vertically and laterally across the front portion of the single unitary member between two of the generally vertical upright frame members. A pair of side panels extends generally vertically, being generally parallel to each other and spaced from each other. Each side panel extends from a front portion to a rear portion of the basket between two of the generally vertical upright frame members. The front panel and each side panel comprise a generally flat portion defining a plurality of holes and have a substantially uniform thickness at least about two times less than a thickness of the generally vertical upright frame members. Though, US’465 discloses about an invention that relates to a basket for a shopping cart. However, the cited invention lacks in providing navigational guidance to the user for locating the required grocery items within the store.

[0006] Conventionally, many devices have been developed that are capable of providing a trolley-shaped accommodating space for storing grocery items during grocery shopping. However, these existing devices are incapable of providing a separate storage space for accommodating various dry and cold grocery items, and fails in maintaining an optimum temperature of the dry and the cold items. Additionally, these existing devices also lack in providing navigational guidance to the user for locating the items within the store that are listed in the shopping list of the user.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a device that requires to be capable of providing a separate storage space for accommodating various dry and cold grocery items during grocery shopping and maintaining an optimum temperature of the dry and the cold items. In addition, the developed device also needs to fetch the shopping list of the grocery items and accordingly requires to provide navigational guidance to the user for locating the listed items within the store.

[0020] In any embodiment described herein, the open-ended terms "comprising," "comprises,” and the like (which are synonymous with "including," "having” and "characterized by") may be replaced by the respective partially closed phrases "consisting essentially of," consists essentially of," and the like or the respective closed phrases "consisting of," "consists of, the like.

[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 grocery shopping assistive device that provides a trolley like dual storage space to a user for separately accommodating various dry and cold grocery items during grocery shopping from a store. Additionally, the proposed device is also capable of accessing the shopping list of the items and accordingly provides information about discounts, deals, and offers available for the listed items in order to ensure cost-effective purchasing.

[0023] Referring to Figure 1, an isometric view of a grocery shopping assistive device is illustrated, comprising a trolley-shaped frame 101 having an upper section 102 and a lower section 103, a pair of handles 104 installed on the frame 101, multiple wheels 105 provided on underside of the frame 101, a touch display panel 106 mounted on the frame 101, a holographic projection unit 107 mounted on the frame 101, an artificial intelligence-based imaging unit 108 installed on the frame 101.

[0024] Figure 1 further illustrates a motorized door 109 arranged on each upper section 102 and lower section 103, an OCR (Optical Character Recognition) sensor 110 is embedded in the frame 101, a heating unit 111 installed in the upper section 102, a refrigeration unit 112 is installed in the lower section 103, multiple slider crank arrangement 113 are installed along edges of each upper section 102 and lower section 103, a microphone 114 and a speaker 115 are provided with the frame 101.

[0025] The device disclosed herein comprises of a trolley-shaped frame 101 that is developed with two distinct sections for storing various grocery items. The upper section 102 is designated for dry storage, accommodating items such as packaged goods, grains, and other non-perishable products. The lower section 103, on the other hand, is configured for cold storage, to store perishable goods like dairy products, frozen items, or fresh produce. The two sections are integrated seamlessly within the trolley frame 101 for creating a compact and functional structure.

[0026] The upper section 102 and lower section 103 of the frame 101 are interconnected through a pair of handles 104 that are installed on the frame 101 for providing easy accessibility and allowing a user to maneuver the trolley comfortably within a retail environment such as a store or any retail spaces. The mobility of the trolley is facilitated by means of multiple wheels 105 (ranging from 4 to 6 in numbers) affixed to the underside of the frame 101. These wheels 105 are designed to provide smooth movement across various flooring surfaces commonly found in retail environments, such as tile or carpeted floors. The wheels 105 are also durable enough to withstand regular use and maintain stability even when the trolley is fully loaded with groceries. This allows users to move the trolley efficiently and without difficulty, even when carrying heavy items.

[0027] The user is required to accesses a touch display panel 106 mounted on the frame 101 and connected to an inbuilt microcontroller, to provide touch input regarding a shopping list of grocery items to be purchased from the store. The display panel 106 serves as the central control unit, allowing the user to interact seamlessly with the device.

[0028] The touch display panel 106 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 shopping list of grocery items to be purchased from the store.

[0029] The microcontroller through various interfaces which may include but are not limited to SPI (Serial Peripheral Interface) or I2C (Inter-Integrated Circuit) processes the user input data to retrieve precise location data for the listed items within the store by accessing a database linked to the microcontroller, containing the store’s inventory layout. The microcontroller ensures that the device identify the exact locations of the items within the store, enabling efficient and accurate navigation for the user to locate and retrieve the desired products with ease.

[0030] Upon retrieving the location data of the listed items, the microcontroller activates a navigation feature using an associated GPS module for generating an optimized routing directions within the store. The directions are then provided as navigational guidance to the user, ensuring a simplified shopping experience by minimizing unnecessary movement and helping the user locate the listed items quickly and accurately.

[0031] The GPS (Global Positioning System) module is a satellite-based navigation system. The satellites present in space moving in fixed orbits transmits information about the real-time location of the listed items. The signals travel at the speed of light and are intercepted by the GPS module such that the GPS module calculates the distance of each satellite and based on the time taken by the information to arrive at the receiver. The GPS module locates four or more satellites and calculates the distance between each of them. Using this information, the GPS module finds out the current location of the listed items. Once the distance is determined, the GPS module uses a trilateration method to determine the exact position of the listed items and thus fetching the real-time location coordinates of the listed items.

[0032] Based on the determined location of the listed items, the microcontroller actuates a holographic projection unit 107 mounted on the frame 101 of the trolley to project real-time routing directions into the proximal space of the user. The directions visually guide the user to the precise location of the listed items within the store. In addition to navigation, the projection unit 107 displays information about current discounts, deals, and special offers associated with the listed items.

[0033] The holographic projection unit 107 comprises of holograms, shutter, beam splitters, diverging lenses and a mirror utilized to project holograms. Firstly, the projector emits the laser beam and passed through the shutter to impact on the beam splitter. After the impact of laser beam, the splitter splits the laser beam into two directions. First part is passes through a diverging lens where it scatters to impact on the mirror and produce reflected beam and another part is passed to another mirror directly where it reflects the beam and pass through another
diverging lens. After that, the reflected beam from first part falls in proximal space to produce an image which guides the user towards the location of the items for efficient and accurate item retrieval.

[0034] Based on reaching the location, the microcontroller actuates an artificial intelligence-based imaging unit 108 installed on the frame 101 of the trolley and paired with a processor for capturing and processing multiple images of the frame 101 as the user retrieves and places items into the trolley. By analyzing the images in real time, the AI module accurately detect the actions of the user, identifying which items are being retrieved and their placement into the appropriate storage sections dry or cold. The AI module then classifies the type of each item, ensuring that it is stored in the correct compartment, and even track inventory or detect any misplaced items, enhancing the overall efficiency and organization of the shopping process.

[0035] The artificial intelligence-based imaging unit 108 comprises of a camera lens and a processor, wherein the 360-degree rotatable camera captures multiple images of the frame 101 and then the processor carries out a sequence of steps including pre-processing, feature extraction and segmentation. In pre-processing, the unwanted data like noise, background is removed out by the AI protocols and the image is converted into a format recommended for feature extraction. The features like pixel intensities of the foreground image are extracted and are sent for classification to determine the type of items being placed in the sections.

[0036] Based on the type of the items being retrieved by the user, the microcontroller actuates a motorized door 109 installed on each of the upper section 102 and the lower section 103 of the trolley to open for allowing the user to easily store retrieved items into the designated storage areas. The motorized mechanism ensures that the doors 109 open and close smoothly and efficiently, without requiring manual effort from the user. The motorized door 109 operates through an arrangement that includes an electric motor, a control unit, and sensors. When the door 109 receives a signal from the microcontroller, the control unit activates the electric motor. The motor then transmits its rotational force through a series of gears, belts, or chains to move the door 109 panels along a track for opening the door 109 and allowing the user to store the retrieved items.

[0037] An OCR (Optical Character Recognition) sensor 110 is embedded within the frame 101 of the trolley and is synchronized with the imaging unit 108 to scan and interpret the text from product labels, specifically focusing on the expiration dates of items stored in the trolley’s sections. The OCR (Optical Character Recognition) sensor 110 covert virtually any type of image containing printed or hand-written character into binary format. For this, the imaging unit 108 firstly captures the images of the products/ grocery items labels which is subsequently transformed into a black and white rendition. The OCR (Optical Character Recognition) sensor 110 further analyzes the image's dark portions to recognize characters and numerals printed on the items.

[0038] When an item is placed into a section, the OCR sensor 110 reads the expiration date and compares it to the current date. When the sensor 110 detects that an item has expired, the microcontroller is triggered to activate the projection unit 107 to visually prompts the user to remove the expired items from the sections to prevent purchasing of the expired items.

[0039] The upper section 102 is equipped with a heating unit 111 that is actuated by the microcontroller for regulating temperature of dry items. The heating unit 111 uses electrical resistance to convert the electric energy into heat energy which is then transferred to an air medium over the wire for maintain the temperature of the grocery items stored inside upper section 102. The heating unit 111 also employs thermostats for regulating the temperature of heat while maintaining the temperature.

[0040] Meanwhile, the lower section 103 is installed with a refrigeration unit 112 that is simultaneously actuated by the microcontroller for maintaining a low temperature for perishable items kept in the lower section 103. The refrigeration unit 112 operates by removing heat from an enclosed space to maintain a lower temperature than its surroundings.

[0041] The process begins with a compressor that pressurizes a refrigerant for raising its temperature. The hot, high-pressure refrigerant flows through a condenser, where it releases heat and condenses into a liquid. This liquid refrigerant passes through an expansion valve, reducing its pressure and temperature. The cold, low-pressure refrigerant then enters the evaporator, absorbing heat from the surrounding air or contents inside the lower section 103 to ensure optimal storage conditions.

[0042] The frame 101 includes multiple slider crank arrangements 113 installed along the edges of both the upper section 102 and the lower section 103 of the trolley that are actuated by the microcontroller in coordination with the imaging unit 108, which continuously monitors the size and quantity of the items being placed inside the sections for adjusting the number and size of the compartments within the sections by controlling the movement of the slider crank arrangement 113.

[0043] The adjustment ensures that the storage space is optimized, with compartments expanding or contracting as needed to accommodate items of varying sizes and quantities. As a result, the device offers flexible and efficient storage management, allowing the user to maximize space usage and keep their items organized, thereby enhancing the overall shopping experience.

[0044] The slider crank arrangement 113 consists of three main components that is a crank, connecting rod, and a slider, wherein the crank is powered by a DC (Direct Current) motor. The crank is a rotating shaft driven by a motor or other power source. The connecting rod is a linear link that connects the crank to the slider. The slider is a sliding element that moves back and forth along a straight line. As the crank rotates, it drives the connecting rod and slider through a series of pivot points, causing the slider to move back and forth that is in a reciprocating motion which is connected to the roller.

[0045] The speed and distance of the slider movement is controlled by adjusting the connecting rod length, the crank speed, or the pivot points position. Thus, the slider crank arrangement 113 converts the rotational motion to a reciprocating motion to adjust the number and size of compartments within the sections, thereby enabling flexible and efficient storage management and optimizing the user’s shopping experience.

[0046] During the retrieval process, the user is required to scan the credentials of each item using the touch display panel 106. The panel 106 includes a real-time billing module that automatically generates an itemized bill as the items are scanned. The module calculates the total cost of the retrieved items, providing the user with an up-to-date summary of their purchase. Once the user has completed the shopping process and made the payment, the microcontroller is configured to communicate with an external printer by means of a communication module which includes, but not limited to Wi-Fi (Wireless Fidelity) module, Bluetooth module, GSM (Global System for Mobile Communication) module associated with the device, to generate a receipt for the transaction.

[0047] The communication module allows the microcontroller to send and receive data to and from the external printer without the need for physical connections. The Wi-Fi module provides connectivity over local networks, enabling real-time communication over longer distances. The Bluetooth module offers short-range, low-power communication, ideal for close proximity. The GSM module allows for communication over mobile networks, facilitating remote monitoring and control from virtually anywhere. This versatile connectivity ensures seamless interaction between the microcontroller and the printer for enabling the microcontroller to communicate with the printer to generate the receipt after payment.

[0048] The microcontroller in association with an integrated geo-fencing module track the location of the device within the store. The module creates virtual boundaries, known as geo-fenced areas, which are predefined zones within the store where the device is allowed to operate. As the device moves, the geo-fencing module continuously monitors its position using the GPS module to ensure that the device stays in designated geo-fenced areas.

[0049] In case the device moves beyond the defined geo-fenced areas, the microcontroller is programmed to send an alert via wireless notifications to multiple computing units, such as store management computer or security personnel gadgets. The notifications provide real-time information about the device's location and movement, allowing the concerned authority to take immediate action. This enhances security by ensuring that the device remains within designated areas, and provides operational control by allowing store personnel to monitor and respond to any unauthorized movement, thus ensuring smooth and safe operation within the store environment.

[0050] During the retrieval of grocery items into the sections, the microcontroller by means of multiple weight sensors (ranging from 4 to 6 in numbers) embedded within both the upper section 102 and the lower section 103 of the trolley, monitor the weight distribution of the stored items inside the compartments. The weight sensors used herein are a particular kind of transducer, more especially a weight transducer, which transform a mechanical force that is applied as an input, by the weight of the stored items, into a change in electrical resistance, which varies proportionally to the force being applied to the sensor. This change in electrical resistance is detected by the microcontroller linked with the sensor, in the form of an electrical signal.

[0051] The microcontroller continuously processes the received signals from all the weight sensors in order to monitor weight distribution of the items stored inside the compartments to ensure that the stored items are evenly distributed within the compartments. If an imbalance is detected, such as one section being overloaded or under filled, the microcontroller sends a notification to the user. This alert is displayed on the display panel 106 for notifying the user to adjust the placement of the items for better balance. Thus, maintaining stability of the trolley during use and ensures that the storage space is utilized efficiently, preventing any potential damage to the device or inconvenience to the user.

[0052] Further, a microphone 114 and a speaker 115 are integrated into the frame 101 for enabling hands-free operation of the device. The microphone 114 and the speaker 115 work together to allow the user to interact with the device using voice commands for making the shopping process more convenient and efficient. The user is required access the microphone 114 to provide input voice commands regarding the desired operation, in their regional language.

[0053] The microphone 114 receives the user voice commands and converts the sound energy emitted by the user into electrical energy. Inside the microphone 114, a diaphragm made of plastic is present that moves back and forth when the sound wave hits the diaphragm, which then moves a coil attached to the diaphragm in the same way in order to generate an electrical signal proportional to the sound. The electric signal from coil flows to an amplifier which amplifies the electrical signal. The amplified electrical signal is then sent to the microcontroller linked to the microphone 114.

[0054] The microphone 114 utilizes Natural Language Processing (NLP) protocols to understand and respond to voice commands in multiple languages, providing a multilingual interface. This allows users to communicate with the device naturally, regardless of their preferred language. Whether the user needs to input their shopping list, request guidance, or receive notifications, the microphone 114 and speaker 115 enable a seamless, voice-driven interaction with the device for understanding and responding to voice commands in different languages.

[0055] Lastly, a battery is installed within the device which is connected to the microcontroller that supplies current to all the electrically powered components that needs an amount of electric power to perform their functions and operation in an efficient manner. The battery utilized here, is generally a dry battery which is made up of Lithium-ion material that gives the device a long-lasting as well as an efficient DC (Direct Current) current which helps every component to function properly in an efficient manner. As the device is battery operated and do not need any electrical voltage for functioning. Hence the presence of battery leads to the portability of the device i.e., user is able to place as well as moves the device from one place to another as per the requirements.

[0056] The proposed invention works best in the following manner, where the trolley-shaped frame 101 having the upper section 102 and the lower section 103 is configured for dry and cold storage. The pair of handles 104 are accessed by the user for facilitating movement of the trolley within the retail environment by means of wheels 105. The user accesses the touch display panel 106 to input the shopping list of grocery items to be purchased from the store. Accordingly, the GPS module generate optimized routing directions for providing navigational guidance to the user for locating the listed items within the store and the holographic projection unit 107 project real-time routing directions in proximal space of the user to guide the user to the precise location of the items within the store along with information about discounts, deals, and offers available for the listed items. Further, the artificial intelligence-based imaging unit 108 paired with the processor detect the items retrieval actions and classify type of the items being placed in the sections. Simultaneously, the motorized door 109 opens up to allow the user for storing the retrieved items into designated sections based on the detected type of item. After which the OCR sensor 110 synchronized with the imaging unit 108 detect expiration dates of the items and upon detection of expired items the projection unit 107 visually prompt the user to remove the expired items from the sections.

[0057] In continuation, the heating unit 111 regulates temperature of dry items stored in the upper section 102 and the refrigeration unit 112 maintains the low temperature for perishable items in the lower section 103. Based on size and quantity of the item’s places inside the sections, multiple slider crank arrangement 113 dynamically adjusts number and size of compartments within the sections. During retrieval the user is required to scan the credentials of the item on the panel 106 which includes the real-time billing module that generates the itemized bill of the scanned items. Furthermore, the geo-fencing module track the device’s location to ensure the device stays in designated geo-fenced areas. The geo-fencing module works in conjunction with the GPS module for offering location-based guidance and triggering specific actions based on the device’s proximity to predefined areas within the store. Multiple weight sensors ensure that the stored items are evenly distributed within the compartments and the microphone 114 and the speaker 115 allows user to perform hands-free operation.
