Replication of dishes with a robotized cooker
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in accurately replicating a one-pot dish in real time or almost real time on remote, robotized slave cookers, which face different initial cooking conditions compared to a robotized master cooker.
Innovation Solution
The solution involves a data-processing system that monitors and controls the replication of a one-pot dish by adhering to the cooking thermograph of the master cooker, shifting it in time for each slave cooker, and adjusting ingredient and spice dispensing accordingly to ensure identical chemical transformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If real-time replication of dishes is performed on remote slave cookers, then dish quality consistency is improved, but the complexity of coordinating different initial cooking conditions worsens
Solution Approach 1:
The system creates a digital copy of the master cooker's thermograph (temperature-time curve) and transmits it to slave cookers. Each slave cooker replicates the dish by following its copied thermograph, ensuring identical thermal processing despite different initial conditions. This copying approach simplifies coordination by providing a universal reference that automatically adapts to local conditions.
Solution Approach 2:
The system adjusts cooking parameters dynamically based on the thermograph data. Each slave cooker modifies its heating power, ingredient addition timing, and other parameters to match the temperature evolution curve of the master cooker. This parameter adaptation allows precise replication while accounting for variations in initial cooking conditions at different locations.
2Manufacturing precision
If thermal processing is adjusted to comply with master cooker's chemical transformation, then dish replication accuracy is improved, but the control system complexity worsens
Solution Approach 1:
The system implements feedback by continuously monitoring the actual temperature evolution at slave cookers and comparing it with the target thermograph from the master cooker. The control system automatically adjusts heating power and processing parameters to minimize deviations, ensuring that chemical transformations match the original dish. This closed-loop feedback simplifies the control complexity by providing automatic correction mechanisms.
3Manufacturing precision
If time-shifted ingredient dispensing is implemented for each slave cooker, then thermalization accuracy is improved, but the synchronization requirements worsen
Solution Approach 1:
The system performs preliminary calculation of the optimal time shift for each slave cooker based on its specific initial conditions (ambient temperature, cooker characteristics, ingredient temperatures). This pre-computed time offset is applied to the thermograph before transmission, allowing each slave cooker to synchronize ingredient dispensing and heating actions without real-time delays. This preliminary action eliminates synchronization delays while maintaining thermalization accuracy.

AI summary
The invention discloses a method of operating data-processing system consisting of at least one server (30), one robotized master cooker (10.0) and one or more robotized slave cookers (10.i), mutually networked, used for monitoring the replication of a one-pot dish prepared on the robotized master cooker (10.0) and in real time on one or several, remotely located, identical robotized slave cookers (10.i). The method is based on a power regulation and control P c,i (t) of all slave cookers (10.1) in order to replicate the thermograph T c,0 (t) of the master cooker (10.0) to satisfy T c,i (t´+Δt i )=T(t') c,0 , where each Δt i defines the time difference in cooking processes. In the simplest version, the control can be executed by the linear response: P c,i (t)=P c,0 (t-Δt i )+A·(T c,0 (t-Δt i )-T c,i (t)), with A as empirically selected constant.
