Solution Overview
Problem
Current cooking methods lack an automated system for end-to-end food preparation and management, often resulting in inefficiencies, safety issues, and nutrient loss, particularly in high-temperature cooking methods like grilling and deep-frying, which require skilled supervision and can lead to burning or overcooking.
Innovation Solution
A distributed automatic food preparation and management system that integrates hardware processors, cloud computing, sensors, and inventory management to analyze user needs, monitor ingredient availability, and automate cooking processes, including pressure baking and cold pressure frying, to ensure precise temperature control and minimal nutrient loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If high-temperature cooking methods like grilling and deep-frying are used, then superior color, texture and flavor are achieved, but nutrients are lost and burning occurs
Solution Approach 1:
The system changes the cooking parameter from high temperature to controlled low temperature cooking. The microprocessor controls heating elements to maintain temperatures below 100°C during steaming and precisely control pressure cooking temperatures, preventing nutrient loss and burning while still achieving desirable food quality through extended cooking time and pressure differential.
Solution Approach 2:
The patent introduces steam as an intermediary medium between the heat source and food. Instead of direct high-temperature contact cooking, steam transfers heat gently at 100°C, preventing burning. The system uses steam generation from water reservoirs and pressure differential to achieve cooking without direct high-temperature exposure that causes nutrient loss.
2Productivity
If pressure cooking is used to speed up cooking process, then cooking time is reduced, but food becomes overcooked and loses color, texture and shape
Solution Approach 1:
The system dynamically adjusts pressure and temperature parameters during cooking. The microprocessor monitors cooking progress and automatically releases pressure at precise moments to prevent overcooking. The pressure gradient is controlled to cook food quickly while maintaining shape, with automatic pressure release mechanisms that stop cooking at the optimal point.
Solution Approach 2:
The system incorporates feedback control through the microprocessor that monitors temperature, pressure, and cooking time. Sensors detect when food reaches desired doneness and automatically adjust or terminate cooking, preventing overcooking. The pressure release is triggered by feedback from temperature and time sensors to maintain food quality.
3Shape
If steaming is used to avoid discoloration and texture loss, then food color and shape are retained, but color loss and flavor loss occur
Solution Approach 1:
The system provides multiple cooking functions within a single device, including steaming, pressure cooking, and conventional heating modes. This allows selection of the most appropriate method for each specific food type and recipe requirement, optimizing both nutrient retention and flavor preservation depending on the cooking task.
Solution Approach 2:
The system uses periodic pressure cycling and intermittent heating patterns to enhance flavor development during cooking. Brief high-temperature exposure periods are alternated with lower temperature periods, allowing Maillard reactions and caramelization to occur periodically for flavor enhancement while maintaining overall gentle cooking conditions that preserve nutrients.
4Object-affected harmful factors
If manual supervision is required for stir-frying or grilling to prevent burning, then cooking skill is needed, but cooking time increases and complexity increases
Solution Approach 1:
The system performs self-monitoring and self-control of the cooking process. Temperature sensors, pressure sensors, and timers automatically regulate heating elements without user intervention. The microprocessor manages the entire cooking cycle, adjusting power levels and timing to prevent burning, freeing the user from active supervision while maintaining cooking quality.
Solution Approach 2:
The patent replaces manual mechanical cooking control with electronic control systems. The microprocessor substitutes for human judgment and timing, using electronic sensors and automated heating control to manage the cooking process. This eliminates the need for skilled manual supervision while achieving consistent, burn-free cooking results.
5Productivity
If deep-frying is used for cooking, then cooking time is reduced and flavor is enhanced, but oil absorption exceeds 25 percent and carcinogens form
Solution Approach 1:
The system fundamentally changes the cooking parameter from high-temperature oil frying to controlled low-temperature steam and pressure cooking. Temperatures are maintained below 100°C during steaming and precisely controlled during pressure cooking, preventing the formation of carcinogens like acrylamide that form at temperatures above 150°C. Cooking efficiency is maintained through pressure differential and optimized heat transfer.
Solution Approach 2:
The patent uses steam and pressurized air as intermediary cooking media instead of hot oil. This eliminates direct contact with large amounts of oil, reducing oil absorption to minimal levels. The steam and pressure differential provide efficient heat transfer for quick cooking without the harmful effects of deep-frying, including carcinogen formation and excessive oil uptake.
