BACKGROUND OF THE INVENTION

[0002] In today’s fast-paced world, there is a growing need for personalized and efficient food preparation systems, especially for individuals with specific dietary needs, health conditions, or fitness goals. Meal planning and cooking based on individual preferences or medical requirements could be a time-consuming and difficult task. People often struggle to prepare meals that match their dietary restrictions or nutritional goals, especially when managing multiple food groups or tracking ingredients.

[0003] Traditionally, personalized diets are prepared manually by individuals, caregivers, or professional nutritionists. This process requires knowledge of food values, health conditions, and cooking methods, which are not always readily available or accurately applied. Manual preparation involves multiple steps like measuring, cutting, cooking, and packaging, all of which are prone to human error. Conventional food preparation appliances such as blenders, cookers, or food processors offer limited automation and are not designed to work in an integrated and intelligent manner. They cannot store user data, customize meals based on medical history, or manage multi-step meal preparation and packaging processes. These devices often require human supervision at every stage, lack real-time quality analysis, and do not support user-specific tracking through labeling.

[0004] US10154762B2 discloses an automated kitchen system having multiple cooking and/or mixing pots and having containers and dispensers for multiple ingredients. A customer or other person or system selects or creates a meal or other food product and the ingredients for the meal or other product are transferred from dispensers to the cooking and/or mixing pots which simultaneously cook and/or mix the ingredients.

[0022] The present invention relates to a personalized diet preparation and packaging device that enables personalized food and beverage creation and packaging, focused on catering to individual nutritional needs and lifestyle preferences in view of ensuring convenience, cleanliness, and precise portioning.

[0023] Referring to Figure 1, an isometric view of a personalized diet preparation and packaging device is illustrated, comprises of a hollow body 101 housing a plurality of upper-side storage chambers 102 having iris holes 103 and liquid ingredient chambers 102 fitted with mini peristaltic pumps 104, a cutting assembly 105 positioned below the storage chambers 102, including a cuboidal ingredient receiving box 105a, a horizontally aligned motorized rotating blade 105b, and a horizontally attached telescopic rod with a vertical pusher 105c, a beverage preparation vessel 106 integrated within the body 101, a cooking assembly 107 is integrated within the body 101 comprising conduits 107a connecting storage chambers 102 to a cooking unit 107b, a motorized stirring unit 107c mounted on a ball-and-socket on the upper inner periphery of the cooking chamber, a vertically aligned pneumatic probe 107d is mounted on the inner top surface of the cooking unit 107b, and a heating element 107e on the base of the cooking unit 107b.

[0024] The Figure 1 further includes a food plate dispensing assembly including a food plate holding unit 108 storing vertically stacked plates, and a horizontal conveyor belt 109 aligned beneath the holding unit 108, a motorized iris unit 110 is connected to the cooking assembly 107 and beverage vessel 106, a wrapping arrangement placed along the belt 109, including a motorized wrapping unit 111 positioned along the belt 109, a labeling arrangement 112 positioned downstream of the wrapping unit 111 includes a motorized printer 112a, and a pair of extendable grippers 112b inside the body 101, and a speaker 113 and microphone module 114 is arranged on the device body 101.

[0025] The present invention includes a hollow body structure 101 incorporating various components associated with the device, developed to be positioned on a ground surface. A user accesses a user-input interface which is installed in a computing unit operatively coupled to a microcontroller, wirelessly by means of a communication module. The user-input interface allows the authorized users to input meal preferences and customization commands.

[0026] The microcontroller is pre-fed with a defined set of instructions to perform various functions. The microcontroller is a small integrated circuit that controls specific functions by executing a program stored in its memory. The microcontroller consists of a central processing unit (CPU), memory, and I/O ports for interacting with external components of the device. Once activated, the microcontroller receives the signal from button and executes instructions to initiate the working of the device. The microcontroller is further integrated with a database that stores comprehensive health-related data for each user, including medical history, allergies, treatment plans, and nutritional requirements. This database enables the device to generate personalized diet plans and monitor nutritional intake in accordance with each user’s health conditions.

[0027] The communication module includes, but not limited to Wi-Fi (Wireless Fidelity) module, Bluetooth module, GSM (Global System for Mobile Communication) module. 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.

[0028] A microphone module 114 is arranged on the exterior of the device that enables voice-based communication, allowing users to issue commands, and interact with the device hands-free. The microphone module 114 is designed to capture audio input from the user. The microphone module 114 consists of an array of sensitive microphones equipped with noise-cancellation and echo-reduction technologies to accurately detect voice commands even in noisy environments. When the user speaks, the microphone converts sound waves into electrical signals, which are then sent to the device’s microcontroller. The microcontroller processes these signals using protocols to identify keywords, commands, or conversational phrases.

[0029] The body structure 101 is equipped with a plurality of upper-side storage chambers 102. Each of these chambers 102 is dedicated to storing specific solid or liquid food ingredients required for meal preparation. The chambers 102 designed for solid ingredients are equipped with iris holes 103 for controlled dispensing, while the liquid ingredient chambers 102 are fitted with miniature peristaltic pumps 104.

[0030] The iris hole functions similarly to the aperture means of a camera. The iris hole consists of multiple overlapping blades arranged in a circular pattern that opens or closes to varying degrees, creating an adjustable opening size to control the amount of solid food particles dispensed by varying the aperture size. When the microcontroller sends a command to dispense a specific quantity, a motor the iris blades to open the hole to a predetermined diameter.

[0031] The miniature peristaltic pump operates by compressing and releasing a flexible tube through which the liquid ingredient flows. Inside the pump housing, a rotor with several rollers rotates around a fixed stator. As each roller presses against the flexible tubing, it squeezes the liquid inside, pushing it forward along the tube in a peristaltic, or wave-like, motion. Because the liquid only contacts the inner surface of the tubing, contamination is minimized. The pump’s speed and rotation direction are controlled by the microcontroller, allowing precise control over the volume of liquid dispensed.

[0032] Both types of chambers 102 are monitored by integrated flow and load sensors to ensure accurate and precise delivery of ingredients into the subsequent processing units.

[0033] The flow sensor is placed along the delivery conduits 107a or tubing and works by detecting the movement of liquid passing through it. The flow sensor used herein is a turbine flow sensor, where a small rotor spins as liquid flows by, generating pulses proportional to the flow rate, or ultrasonic flow sensors, which use sound waves to measure fluid velocity without direct contact. For solid particles, optical flow sensors are used to detect the movement of granular material. The sensor outputs electrical signals that are processed by the microcontroller to calculate the exact amount dispensed, allowing real-time adjustment of dispensing to maintain precision.

[0034] The load sensors are installed beneath the storage containers to continuously monitor the weight of the contents. When ingredients are dispensed, the load sensor detects the decrease in weight, converting this mechanical change into an electrical signal proportional to the load. This signal is then sent to the microcontroller to calculate the precise quantity removed. By combining weight measurement with flow data, the microcontroller cross-verifies the amount of ingredient dispensed, detect anomalies like blockages or leaks, and ensure accurate ingredient delivery.

[0035] A cutting assembly 105 is located beneath the storage chambers 102 to process solid ingredients such as fruits and vegetables. This cutting assembly 105 includes a cuboidal box 105a that receives the ingredients, a horizontally aligned motorized rotating blade 105b fitted with an RPM sensor to monitor and control blade speed.

[0036] The cuboidal box 105a serves as the primary containment unit where solid ingredients such as fruits and vegetables are collected and held before processing. Its shape and size are designed to accommodate a specific volume of ingredients and to facilitate easy feeding from the storage chambers 102 above. The box’s 105a interior is smooth and constructed from food-grade materials to ensure hygiene and prevent ingredient sticking. This containment ensures that ingredients remain localized and properly positioned for efficient cutting by the rotating blade 105b, minimizing spillage and cross-contamination.

[0037] The motorized rotating blade 105b is driven by an electric motor, the blade spins at controlled speeds to slice, chop, or dice the solid ingredients into predetermined sizes. The blade’s horizontal alignment allows it to cut through the entire ingredient mass evenly, with gravity assisting in feeding the ingredients downward toward the blade. The motor’s power and blade design are optimized to handle a range of ingredient textures, from soft fruits to tougher vegetables, ensuring consistent cutting without damaging the ingredients or the device.

[0038] The RPM (revolutions per minute) sensor is integrated with the motorized blade assembly to continuously monitor the rotational speed of the blade. This sensor uses optical sensing techniques to detect the number of blade rotations per unit time. The data from the RPM sensor is fed back to the microcontroller, which adjusts the motor’s power supply to maintain the blade at an optimal speed for precise cutting. By controlling blade speed, the microcontroller ensures that ingredients are cut efficiently and uniformly, preventing undercutting or overcutting, and accommodating different ingredient types and sizes based on user-defined parameters.

[0039] The cutting unit 105 also includes a horizontally mounted telescopic rod equipped with a vertical pusher 105c on one side. The microcontroller sends a signal a pneumatic unit associated with the telescopic rod that includes an air compressor, air cylinder, air valves and piston which works in collaboration to aid in extension and retraction of the telescopic rod. The microcontroller sends a signal to the pneumatic unit associated with the link 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 rod and due to applied pressure the telescopic rod extends and similarly, the microcontroller retracts the telescopic rod 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 telescopic rod.

[0040] The microcontroller activates the telescopic rod, causing it to extend horizontally into the box 105a. Once fully extended, the vertical pusher 105c moves down to gently press the ingredients toward the center or directly toward the rotating blade 105b. The movement of the pusher 105c ensures that the ingredients are continuously fed into the cutting zone, reducing the chance of ingredients getting stuck at the edges or remaining unprocessed. After the pushing operation, the rod retracts back to its original position to allow the next batch of ingredients or to prepare for cleaning.

[0041] The device also features a cooking assembly 107 integrated within its body 101 to prepare meals based on the user's dietary needs. This cooking assembly 107 consists of a cooking unit 107b with a network of conduits 107a that guide ingredients from the storage chambers 102 to the cooking unit 107b according to the predefined diet plan.

[0042] A heating element 107e is installed along the lower surface of the cooking unit 107b and is coupled with a temperature sensor to achieve and maintain specific cooking temperatures. The temperature sensor used herein is a thermocouple that is embedded or placed in close thermal contact with the cooking chamber. This sensor continuously monitors the real-time temperature within the cooking unit 107b and sends this data to the microcontroller. The thermocouple is a temperature sensing device made by joining two different metal wires at one end, called the measuring junction.

[0043] When this junction experiences a change in temperature, it generates a small voltage that is proportional to the temperature difference between the measuring junction and the other ends of the wires, called the reference junctions. As the cooking unit 107b heats up, the measuring junction detects the temperature changes and produces a corresponding voltage signal. This voltage signal is transmitted through the thermocouple wires to the microcontroller, which is equipped with an analog-to-digital converter (ADC). The microcontroller converts the voltage into a digital temperature reading using calibration data specific to the thermocouple type.

[0044] The heating element 107e comprises electric heating element 107e such as resistive coils that convert electrical energy into heat when powered by a motor, controlled by the microcontroller. The heat generated is evenly distributed across the base of the cooking unit 107b to warm the food uniformly from below. When the temperature falls below the preset cooking temperature as compared to a pre-defined database, the microcontroller increases the power to the heating element 107e to raise the temperature.

[0045] For thorough mixing of the ingredients during cooking, a motorized stirring unit 107c is mounted on a ball-and-socket joint along the upper inner periphery of the cooking unit 107b. The motorized stirring unit 107c consists of a stirring arm driven by an electric motor that imparts rotational motion to mix the ingredients inside the cooking unit 107b. This stirring unit 107c is mounted on the ball-and-socket joint fixed along the upper inner periphery of the cooking unit 107b, providing it with a wide range of multi-directional movement. The ball-and-socket joint functions like a flexible pivot, allowing the stirring arm to tilt and rotate in multiple directions rather than being limited to a single plane. This flexibility enables the stirring unit 107c to reach different areas within the cooking unit 107b, promoting uniform mixing and preventing ingredients from sticking to the sides or bottom.

[0046] The stirring unit 107c supports multi-directional motion and is integrated with an RPM sensor to regulate the stirring speed based on cooking requirements. The RPM sensor, typically using optical or magnetic methods, detects how fast the stirring arm is rotating and sends this data as real-time feedback to the microcontroller. Based on the specific cooking requirements programmed into the microcontroller that analyzes the RPM data and dynamically adjusts the motor’s power supply to increase, decrease, or maintain the stirring speed. For example, slower stirring may be required for delicate ingredients or simmering, while faster stirring could be necessary for thicker mixtures or vigorous cooking.

[0047] To ensure the quality and safety of the prepared food, a vertically aligned pneumatic probe 107d is installed on the inner top surface of the cooking unit 107b. This probe 107d is equipped with a pH sensor, a composition sensor, and a temperature sensor, enabling it to evaluate the acidity, nutrient composition, and temperature of the cooked food, thereby validating its compliance with the user’s dietary and nutritional standards.

[0048] The pH sensor measures the acidity or alkalinity of the cooked food by detecting the concentration of hydrogen ions in the food mixture. The pH sensor uses a glass electrode that develops a voltage proportional to the pH level of the sample it contacts. When the pneumatic probe 107d lowers into the food, the pH sensor comes into contact with the sample, and the voltage signal generated is converted into a pH value by the microcontroller. This measurement helps ensure that the food’s acidity is within safe and desired levels, which is critical for both taste and safety, as certain diets require monitoring of acidic content.

[0049] The composition sensor analyzes the nutrient content of the cooked food, such as proteins, carbohydrates, fats, and other essential components. The composition sensor often uses spectroscopy techniques, like near-infrared (NIR) spectroscopy where light is directed onto the food, and the reflected or transmitted light is analyzed to determine molecular composition. The sensor sends this data to the microcontroller, which interprets it to verify that the food meets the specified nutritional standards. This ensures that the meal complies with personalized dietary requirements, such as low sugar or high protein content.

[0050] The temperature sensor embedded in the pneumatic probe 107d monitors the internal temperature of the cooked food in real-time. The temperature sensor used herein is a thermocouple that provides precise temperature readings by measuring the actual temperature inside the food, and ensures that cooking has reached the required level to guarantee food safety (e.g., killing harmful bacteria) and proper texture. The temperature data is fed to the microcontroller to confirm that the food has been cooked thoroughly according to the user’s dietary settings.

[0051] For beverage preparation, such as smoothies or health drinks, the device includes a beverage preparation vessel 106 integrated within the body 101. This beverage preparation vessel 106 is equipped with a motorized rotating blade that blends the transferred ingredients into a uniform liquid mixture. The motorized rotating blade is centrally mounted inside the beverage preparation vessel 106 and is driven by an electric motor located either beneath or within the vessel’s 106 base. When activated, the motor spins the blade at high speeds, generating strong centrifugal forces and turbulent flow within the vessel 106. The rapid rotation causes the ingredients to be repeatedly pulled toward the blade and pushed outward against the vessel 106 walls, creating a vortex that thoroughly mixes all components.

[0052] Once the meals or beverages are prepared, they are directed to a food plate dispensing assembly located beneath the cooking and beverage units. The food plate dispensing assembly includes a food plate holding unit 108 designed to store multiple rectangular plates in a vertically stacked configuration. A plate separation arrangement is positioned at the base of this unit and releases one plate at a time onto a horizontal conveyor belt 109, which transports the separated plate to the appropriate dispensing station.

[0053] The food plate holding unit 108 consists of a sturdy frame with guides to keep the plates aligned and stable. The stacked configuration ensures that plates are readily available in a sequential order, allowing smooth dispensing without manual intervention. Gravity assists in keeping the plates properly seated, while the unit’s design prevents plates from sticking together or shifting, ensuring reliable plate release.

[0054] The plate separation arrangement located at the base of the holding unit 108, is responsible for releasing one plate at a time from the stacked pile. This arrangement includes a spring-loaded finger that carefully push or pull the bottom-most plate forward while preventing the rest of the stack from moving. By separating plates individually, this device avoids jamming or multiple plates being dispensed simultaneously, ensuring a smooth and controlled flow of plates.

[0055] The horizontal conveyor belt 109 is positioned beneath the plate separation arrangement and is responsible for transporting the separated plate to the dispensing station. The conveyor belt 109 is powered by a motor and moves plates horizontally along a defined path with consistent speed and alignment. The belt surface provides enough friction to prevent plate slippage while ensuring gentle handling to avoid damage and facilitate seamless transfer of plates to receive the prepared meals.

[0056] The dispensing of the prepared food and beverages is facilitated through a motorized iris unit 110 connected to both the beverage preparation vessel 106 and the cooking assembly 107. This iris unit 110 dispenses the prepared contents through a tube aligned with the container on the belt 109, ensuring accurate and clean delivery of food and beverages. The motorized iris unit 110 functions like an adjustable aperture, composed of multiple overlapping blades arranged in a circular pattern. When closed, the blades converge to seal the dispensing outlet, preventing any spillage or contamination. When dispensing is required, a motor drives the blades to rotate and slide over each other, gradually opening the aperture to a precise diameter.

[0057] This adjustable opening is aligned with a tube that connects the cooking assembly 107 and beverage preparation vessel 106 to the dispensing area above the food or drink containers on the conveyor belt 109. The microcontroller controls the motorized iris unit 110 to open only when the container is correctly positioned beneath the tube, as detected by sensors along the belt 109. Once open, the prepared food or beverage flows through the tube and the iris opening directly into the container. After dispensing, the iris blades close tightly to seal the outlet, maintaining hygiene and preventing cross-contamination between servings.

[0058] Following the dispensing stage, the containers are transported to a wrapping arrangement integrated into the device body 101 to ensure hygiene and safety. The wrapping arrangement includes a motorized wrapping unit 111 located along the belt’s 109path that applies a protective film or covering around each plate or glass. The motorized wrapping unit 111 is equipped with a motor that controls the movement and application of a protective wrapping film or covering, such as plastic wrap or shrink film.

[0059] As a container reaches the wrapping station, sensors detect its presence and trigger the motorized wrapping unit 111 to initiate the wrapping process. The motor drives rollers or spools that feed the wrapping film from a roll towards the container. The film is carefully guided and stretched around the container by a gripper to ensure an even and secure covering. The motor controls the speed and tension of the film to avoid tearing or loosening. Once the container is fully wrapped, the motorized unit activates a cutter or sealer that trims and seals the film, completing the wrapping process.

[0060] An infrared (IR) sensor is mounted externally above the wrapping unit 111 to detect the completion of the wrapping process before allowing the container to proceed. infrared (IR) sensor emits a beam of infrared light directed towards the container. When a container moves into the sensor’s detection zone, the IR light reflects off the surface of the wrapped container and is received by the sensor’s photodetector. The sensor measures the intensity and timing of the reflected IR signal to determine the presence and position of the container. After the wrapping process is complete, the IR sensor verifies that the container is fully wrapped by detecting the expected reflective surface of the film or the container’s outline. If the sensor detects an unwrapped or partially wrapped container (which may have a different reflective characteristic), it sends a signal the microcontroller to halt further movement or trigger an alert for manual inspection.

[0061] Subsequently, the wrapped container enters the labeling section of the device having a labeling arrangement 112 that consists of a motorized printer 112a mounted above the belt 109, downstream of the wrapping unit 111. The motorized printer 112a is typically a thermal printer designed to print identification stickers or labels in real-time. As a wrapped container approaches the labeling station, sensors detect its presence and send a signal to the microcontroller to initiate printing. The printer 112a then automatically generates a label containing user-specific information such as identification details, dietary data, and tracking codes based on data stored in the device’s database. The printer 112a motor drives the label feed, advancing the label material (such as adhesive sticker paper) to the print head where the desired information is printed quickly and accurately.

[0062] Upon detecting a wrapped item through a built-in IR sensor, the printer 112a automatically generates a sticker containing user identification details. The IR sensor emits an IR light beam directed at the belt 109surface where the container passes. When a wrapped container moves into the sensor’s detection zone, the IR light reflects off the container’s surface and is received by the sensor’s photodetector. This reflection triggers the sensor to send a real-time signal to the microcontroller, confirming that a wrapped item is correctly positioned for labeling. Upon receiving this signal, the microcontroller activates the printer 112a to automatically generate a sticker. The printer 112a retrieves user-specific identification details stored in the device’s database and formats them into a printable label.

[0063] A pair of extendable grippers 112b within the body 101 is used to pick up and affix the sticker accurately onto the top surface of the wrapped plate or beverage glass, ensuring reliable identification and traceability for each meal or drink prepared. The grippers 112b are designed to accurately pick up printed stickers from the printer’s 112a output area and apply them onto the top surface of the wrapped plates or beverage glasses as they move along the belt 109.

[0064] The grippers 112b use suction pads or finely tuned mechanical fingers to gently grasp the sticker without damaging or wrinkling it. The extension is controlled by motors, allowing precise positioning in three-dimensional space. Once the sticker is securely held, the grippers 112b retract and move toward the wrapped container positioned on the belt 109. Using precise motion control, the grippers 112b align the sticker with the container’s top surface and press the sticker onto the wrapping, ensuring full adhesion without bubbles or misalignment.

[0065] To further enhance user interaction and accessibility, a speaker 113 is arranged on the exterior of the device that receive status updates, and delivers real-time updates to the user. The speaker 113 module is responsible for providing audible feedback to the user. The speaker 113 works by converting the electrical signal into the audio signal. The speaker 113 consists of a cone known as a diaphragm attached to a coil-shaped wire placed between two magnets. When the electric signal is passed through the voice coil, generating a varying magnetic field that interacts with the magnet causing the diaphragm to move back and forth. This movement pushes and pulls air creating sound waves just like the electrical signal received and used to notify the user. The speaker 113 module converts electrical signals from the microcontroller and delivers responses, status updates, alerts, or prompts, allowing users to interact with the device without needing to look at a screen. This is particularly useful for users who may have mobility constraints or prefer voice control over manual input.

[0066] 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.

[0067] The present invention works best in the following manner, where the present invention includes the hollow body 101 installed with the plurality of upper-side storage chambers 102, each configured to hold specific solid and liquid food ingredients for diet preparation. Upon receiving user commands via the input interface or voice interaction, the microcontroller accesses personalized dietary data to initiate meal preparation. Solid ingredients are precisely cut in the cuboidal cutting box 105a by the motorized rotating blade 105b pushed by the telescopic rod. These ingredients, along with liquids, are dispensed through conduits 107a into the cooking unit 107b, where the heating element 107e and motorized stirring unit 107c maintain optimal cooking conditions, monitored by temperature, pH, and composition sensors for quality assurance. The prepared food and beverages are then dispensed via the motorized iris unit 110 into containers positioned on the conveyor belt 109. The belt 109transports these containers to the plate dispensing assembly 110, which releases plates one-by-one for meal receiving. Following dispensing, the motorized wrapping unit 111 applies protective coverings, verified by the infrared sensor. Finally, the motorized printer 112a generates user-specific labels triggered by another IR sensor, and extendable grippers 112b affix the labels to the wrapped containers, ensuring safe, hygienic, and personalized meal delivery.
