Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern induction hobs require high power due to large cooking zones, but existing configurations with multiple modules are complex and limited, necessitating additional components and complex circuitry to achieve higher power outputs.
Innovation Solution
The method involves using at least two synchronized generators to provide an overload power greater than standard maximum power for a limited time, determined by the integral of loadings and component properties, without additional components, to avoid component destruction, and operates at standard maximum power for permanent operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If multiple modules are coupled together to provide higher power output, then the power output is improved, but the device complexity increases due to additional switching components and complex circuitry
Solution Approach 1:
The patent merges two synchronized generators into a single control system that shares common control circuitry and switching components. The control device manages both generators using integrated control logic that coordinates their operation, allowing power outputs to be combined without requiring separate control systems for each generator, thus reducing overall device complexity while maintaining high power output capability
2Power
If overload power is activated for extended periods, then the power output is improved, but the reliability decreases due to risk of component destruction
Solution Approach 1:
The control device implements periodic action by activating overload power only for predetermined limited time intervals between standard operating cycles. The control logic monitors elapsed time and automatically deactivates overload power before component damage can occur, allowing the system to deliver high power outputs periodically while maintaining component reliability through enforced rest periods
Solution Approach 2:
The control device incorporates feedback mechanisms that monitor the operational state and time duration of overload power activation. Based on this feedback, the control logic dynamically adjusts the timing and duration of overload power delivery, deactivating it when predetermined time limits are reached to prevent component destruction, thus maintaining reliability while enabling high power output when needed
3Power
If synchronized generators are used to provide overload power, then the power output is improved, but the ease of operation decreases due to coordination requirements
Solution Approach 1:
The control device merges the control functions for multiple synchronized generators into a single integrated control unit. This unified controller automatically coordinates the generators' operation, synchronizes their power outputs, and manages the timing of overload power activation without requiring manual coordination, thereby maintaining ease of operation while enabling high power output capability

AI summary
The present invention relates to a method for controlling a cooking device, in particular an induction hob. The method comprises the steps of - activating an overload power (POVER) for at least one electric or electronic component of the cooking device by using at least two synchronized generators, which overload power (POVER) is greater than a standard maximum power (PMAX), - deactivating the overload power (POVER) after a predetermined period (Δt) , and - operating the cooking device at a power (P), which is at most the standard maximum power (PMAX). The standard maximum power (PMAX) is provided for a permanent operation of the cooking device, - the overload power (POVER) and/or the period (Δt) are determined by a function depending on at least the overload power (POVER) and the period (Δt). The present invention relates further to a corresponding apparatus for controlling a cooking device, in particular an induction hob.
