Cooktop Heating Zone Transfer for Moved Cookware
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hob technologies with matrix heating elements struggle to provide an intuitive and user-friendly method for creating and managing freely definable heating zones, especially when cookware is moved or rearranged, leading to complications in maintaining set temperatures and cooking programs.
Innovation Solution
A method that uses a detection arrangement and control unit to identify the movement of cookware, automatically shifting and adapting heating zones based on the cookware's position, size, shape, and material properties, allowing for seamless continuation of cooking processes without requiring users to re-adjust settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the hob uses a matrix of small heating elements arranged in a grid to form flexible heating zones, then the adaptability to different cookware sizes and shapes is improved, but the ease of operation deteriorates because users must manually re-adjust temperature settings when moving cookware
Solution Approach 1:
The control unit automatically detects cookware position changes using the detection arrangement and autonomously shifts the heating zone and maintains temperature settings without user intervention. The system serves itself by monitoring its own state and making necessary adjustments, eliminating the need for manual reconfiguration when cookware is moved.
Solution Approach 2:
The detection arrangement continuously monitors cookware position and provides feedback to the control unit. Based on this feedback, the control unit automatically adjusts the heating zone configuration and maintains temperature settings, creating a closed-loop system that responds dynamically to user actions without requiring explicit re-adjustment.
2Ease of operation
If the hob automatically detects and tracks cookware movement to maintain heating zones, then the ease of operation is improved, but the device complexity increases due to advanced detection and control mechanisms
Solution Approach 1:
The detection arrangement serves multiple functions: it detects cookware presence, determines cookware position, identifies cookware material properties, and triggers appropriate control responses. By making this single component multi-functional, the patent avoids adding separate detection systems for each function, thereby limiting the increase in device complexity while achieving automatic cookware tracking and heating zone maintenance.
3Reliability
If the hob uses temperature sensors and control units to maintain precise temperature control, then the reliability of cooking processes is improved, but the device complexity increases due to additional sensors and control mechanisms
Solution Approach 1:
The patent combines the temperature control function with the automatic cookware tracking function. The same control unit that manages heating element activation also responds to detection arrangement signals for position changes. By merging these control functions into a single integrated unit rather than separate systems, the patent maintains reliable temperature control during cookware movement without proportionally increasing device complexity.

AI summary
The invention relates, in particular, to a method for operating a cooktop having a plurality of heating elements. The method comprises detecting a cookware element by means of a detection assembly, forming a heating zone consisting of a heating element or a plurality of heating elements, which heating zone is adapted to the detected cookware element, and setting at least one target temperature of the heating zone by means of a user interface. According to the invention, in particular a process is detected by the detection assembly, which process comprises removing the cookware element from an initial position and subsequently placing the cookware element in a final position. The method also comprises associating the process with one of at least two cases by means of the control unit. In a first case, the process is interpreted as a movement of the same cookware element from the initial position to the final position. In further cases, the control unit independently recognizes that the same cookware element is not moved, but rather one cookware element is removed and a new cookware element is placed. At the least in the first case of the movement of the same cookware element, the control unit moves the heating zone from the region of the initial position to the region of the final position. For this purpose, new heating elements are associated with the heating zone and at least some of the heating elements originally associated with the heating zone are removed or deactivated. At least in the first case, which relates to a movement of the same cookware element, the originally set target temperature is carried over for the moved heating zone by the control unit. In the further case, the target temperature is set to a default value by the control unit.
