Description

Technical Field

[0001] This invention belongs to the interdisciplinary technical fields of human nutrition and health management, scientific weight loss, intelligent dietary control and smart catering equipment. Specifically, it relates to a smart tableware with zoned weighing, high waterproof and easy cleaning, and more particularly to a wireless interconnected intelligent dietary closed-loop system that integrates a dietary health management system. It can adapt to the differentiated dietary control needs of ordinary healthy people, people with special physical conditions and health care groups, and is applicable to all scenarios such as family healthy diet, refined management of personal physical condition, calorie control of canteen group meals and food procurement accounting. Background Technology

[0002] With the increasing health awareness of the public, quantified diets, scientific proportions, and personalized nutritional regulation have become mainstream health needs. Different users have different physical conditions, dietary goals, and dietary intake restrictions, making it difficult for conventional dietary equipment to meet tiered and refined dietary management standards. Existing smart tableware mostly only has basic weighing and statistical functions, resulting in low data utilization and an inability to establish differentiated dietary management logic based on user physical characteristics, dietary restrictions, and health goals, thus exhibiting weak personalized adaptation capabilities.

[0003] Meanwhile, existing equipment has poor anti-interference capabilities for zoned weighing, insufficient waterproof rating, and weak structural versatility. It cannot meet the diverse needs of daily dining, refined physical condition management, special dietary control, and large-scale group meal accounting. There are obvious defects in technical adaptability and intelligent system.

[0004] In summary, existing technologies cannot simultaneously achieve the integrated application of high-precision zoned metering, high-level waterproof and stain-resistant structures, universal dietary management, and personalized dietary adaptation to individual body constitutions, leaving a significant technological gap. Summary of the Invention

[0005] This invention addresses the shortcomings of existing technologies by solving the technical problems of traditional smart tableware, such as easily interfered weighing accuracy, poor cleanability, limited intelligence, and lack of personalized dietary management capabilities. It provides a smart tableware that integrates a dietary health management system, constructing a closed-loop management system covering ordinary daily diet, personalized weight loss and calorie control, dietary regulation for special body types, and ingredient procurement accounting. It also has structural stability and mass production capabilities, and possesses good practical value and industrialization prospects. Technical solution (I) Overall Structure of Tableware

[0006] A smart tableware system integrating dietary health management includes a three-level interconnected architecture of a smart tableware terminal, a mobile smart terminal, and a cloud-based health management platform. The smart tableware terminal transmits data bidirectionally to the mobile smart terminal via low-power wireless communication, and the mobile terminal interacts with the cloud platform in real time, constructing a smart dietary closed-loop system that integrates hardware perception, algorithm analysis, and personalized physical condition regulation. (II) Intelligent Weighing Tray Terminal Structure

[0007] The smart tableware terminal includes a main plate, a weighing sensor layer, and a sealed protective base. The main plate can be flexibly designed with either a recessed integrated structure or an independent recessed partition structure, allowing for the design of single or multiple independent holding spaces as needed. This enables zoned measurement of ingredients, meeting the refined and differentiated dietary ratio monitoring needs of various users. The smart tableware terminal uses a food-grade silicone horizontal interference-sealed structure, combined with a vertical clearance-avoidance design to avoid vertical stress interference. The entire unit is waterproof and stain-resistant, supporting full-machine washing and dishwasher cleaning, making cleaning and maintenance convenient.

[0008] The integrated grooved tray is made of food-grade material in one piece, with rounded corners. It features adjustable weighing zones and isolation partitions to effectively prevent spillage and food mixing. Each zone has an independent support boss at the bottom, and the tray is suspended in a hollowed-out position to minimize rigid stress transmission and physically isolate weighing interference between zones. A limiting base at the bottom ensures stable placement, uniform stress distribution, and consistent weighing accuracy over the long term. A transverse silicone interference seal is used between the tray and the base, bearing only lateral compressive force without vertical pre-stress, thus avoiding any impact on testing accuracy from the sealing structure.

[0009] The recessed independent plate can be designed with multiple independent weighing grooves as needed. The groove structure is rigidly integrally molded with independent bottom support and zone isolation. The outer perimeter of the plate is sealed with food-grade silicone radial interference seal, which has excellent blocking effect on water vapor and soup. Each weighing area is independently suspended and subjected to force, with only the corresponding sensor bearing vertical pressure, while the other areas are physically isolated, realizing independent and accurate weighing in multiple zones. It can meet the high-precision measurement needs of refined diet ratio and restricted diet monitoring.

[0010] The weighing sensing layer is sandwiched between the main body of the plate and the sealed protective base, integrating multiple pressure sensors, information acquisition modules, wireless communication and data calibration chip units; it has a built-in temperature compensation module and partitioned weight matrix decoupling algorithm, which can calibrate the crosstalk error of multi-partition synchronous weighing in real time, with high measurement accuracy and strong environmental adaptability; the whole machine circuit is highly integrated and compact, with no redundant discrete components, and better sealing and assembly consistency.

[0011] The sealed protective base is made of non-slip hard material, has a built-in rechargeable battery, is equipped with a magnetic wireless charging or waterproof charging interface, and is covered with a non-slip silicone pad on the bottom; the entire circuit is sealed and encapsulated, meeting waterproof and anti-fouling standards, with a simple structure, and is suitable for large-scale mold mass production.

The system can automatically adapt to general dietary standards, fat loss and calorie control standards and special physical condition restrictive dietary standards to generate tiered personalized nutrition intake plans.

[0015] Dietary closed-loop feedback module: Based on users' real meal data and personal health baseline, it intelligently analyzes the rationality of dietary structure and outputs adaptive dietary adjustments, intake restrictions and lifestyle and exercise suggestions for users with different physiques, so as to achieve stratified and precise dietary guidance.

[0016] Data storage module: It adopts dual backup storage in local and cloud, which can retain dietary records, nutritional intake patterns and health optimization progress for a long time. It supports data backtracking, statistics and export, and is suitable for chronic disease management and long-term health management needs. Cloud-based health management platform module

[0017] Data platform module: It aggregates dietary and health data from multiple users and terminals, establishes standardized personal dietary records and group dietary databases, and realizes unified data collection and management.

[0018] Algorithm analysis engine: Relying on dietary big data models, it deeply correlates users' body type, dietary preferences, nutrient intake and health change patterns, dynamically iterates and adapts personalized dietary control strategies for different groups of people, and improves the accuracy of dietary guidance.

[0019] Ecosystem Collaboration Module: Connects with health management services and dietary guidance systems to support personalized dietary optimization; it also supports batch user management and group nutrition trend analysis for campuses and corporate catering.

[0020] Food Procurement Calculation Module: For group meal scenarios, this module automatically calculates the required quantity of various food ingredients based on the number of diners, general dietary standards, and differentiated proportioning requirements, generating a standardized procurement list to reduce food waste. (iv) Closed-loop control process

[0021] Step 1: Dietary Data Collection: Users place their meals in designated areas, and sensors in each area independently collect weight signals. After temperature compensation, matrix decoupling, and stress calibration, the data is uploaded to the mobile terminal via a wireless module.

[0022] Step 2, Nutritional Quantification and Analysis: The terminal matches the food database to accurately calculate the nutritional and calorie data of a single meal, and generates personalized dietary assessment results by combining the user's body type and dietary standards.

[0023] Step 3: Cloud Data Synchronization: The mobile device will synchronize and upload dietary data, user physical parameters, and personalized dietary profiles to the cloud platform.

[0024] Step 4: Intelligent System Analysis: The cloud-based system combines historical data and big data algorithms to assess the rationality of dietary structure. Based on the health goals and physical limitations of different users, it outputs differentiated dietary optimization plans and simultaneously completes the calculation of food requirements.

[0025] Step 5: Visualized and Precise Control: Personalized dietary guidance, dietary optimization suggestions, and ratio adjustment plans are distributed from the cloud to the terminal to achieve visualized, tiered, and refined dietary management.

[0026] Step Six: Iterative Closed-Loop Optimization: Continuously collect user dining data, dynamically update personal dietary plans, and form a long-term iterative closed-loop system for dietary health management that is suitable for various physiques and different groups of people.

It can simultaneously adapt to the diverse management needs of ordinary daily diet, fat loss and calorie control diet and special body constitution diet, with a wider range of intelligent adaptation dimensions and stronger systematic management capabilities.

[0028] This invention employs a transverse interference seal combined with a vertical suspension stress-avoidance structure, along with a dual anti-crosstalk design using physical isolation and matrix decoupling algorithms. This addresses the industry challenges of poor accuracy and mutual interference in multi-zone synchronous weighing, ensuring the high precision requirements for refined nutritional formulation and restrictive diet monitoring.

[0029] The entire machine features a high-level waterproof and stain-resistant design, allowing it to be fully washed or cleaned by a dishwasher. This solves the problems of traditional smart tableware, such as difficulty in cleaning, poor waterproofing, and limited daily use, making it suitable for high-frequency dining scenarios such as families, health and wellness centers, and canteens.

[0030] The equipment features highly integrated circuitry, a simple structure, easy assembly, and is compatible with integrated mold molding for mass production. Its industrialization costs are controllable and it has strong scalability.
