Core Temperature Tracking for Residual Cooking Time Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users lack a reliable method to determine the residual time until a cooking process is completed, as they typically rely on experience or cookbooks, and measuring core temperature only indicates consistency without providing information on the remaining cooking time.
Innovation Solution
A method involving defining a set temperature value, measuring core temperatures at predetermined times, determining the time dependence of these temperatures, comparing them to the set value, and estimating the residual cooking time, which can be updated regularly using a control unit and food probe, allowing for automatic process termination based on predetermined criteria.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the user measures the core temperature of the foodstuff to check cooking consistency, then the user can determine if the cooking process has been finished, but the user cannot determine the residual time until the cooking process is finished
Solution Approach 1:
The system continuously measures the core temperature and feeds this information back to the control unit, which compares the measured temperature progression against the set temperature value to dynamically calculate and update the residual time estimate, providing real-time feedback to the user about both temperature status and remaining cooking time
Solution Approach 2:
The control unit performs preliminary calculations by comparing the measured temperature progression with the set temperature value before the cooking process completes, estimating the residual time in advance and providing this information to the user proactively rather than waiting until the cooking is finished
2Ease of operation
If the user relies on experience or cookbooks to determine cooking time, then the cooking process can be simple to operate, but the actual consistency of the foodstuff cannot be reliably determined
Solution Approach 1:
The oven system performs self-monitoring by automatically measuring the core temperature and calculating the residual time without user intervention, eliminating the need for users to rely on experience or cookbook knowledge while maintaining operational simplicity
Solution Approach 2:
The system replaces manual judgment based on user experience or cookbook guidelines with automated electronic temperature measurement and computational analysis, substituting mechanical/simple operation with intelligent control to achieve reliable consistency determination
3Manufacturing precision
If the cooking process is monitored continuously to determine residual time accurately, then the cooking precision is improved, but the device complexity increases
Solution Approach 1:
The control unit performs multiple functions including temperature measurement data acquisition, temperature progression analysis, residual time calculation, and user interface management, consolidating these functions into a single multi-functional device to minimize overall system complexity while achieving precise cooking monitoring

AI summary
The invention relates to a method for determining the residual time until a cooking process of a foodstuff (12) has been finished. At first a set temperature value for a core (14) of the foodstuff (12) is defined. Next the actual temperatures in the core (14) of the foodstuff (12) at predetermined times are measured and the time dependence of the measured temperature in the core (14) of the foodstuff (12) is determined. At last the time dependence of the measured temperature is compared with the set temperature value and “the residual time of the cooking process is estimated. The invention relates further to a corresponding apparatus for determining the residual time until a cooking process of a foodstuff (12) has been finished.
