Cooktop having a plurality of heating elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooktops with matrix heating elements lack convenience in managing heating zones, as users must reset target temperatures and parameters when repositioning cookware, disrupting cooking processes and requiring manual intervention.
Innovation Solution
A method that detects cookware movement and position using a detection arrangement, allowing the control unit to adapt heating zones and maintain target temperatures and parameters, either carrying them over or resetting them based on user input and sensor data, ensuring seamless cooking process continuation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cooktop uses multiple heating elements arranged in a grid, then the flexibility to adapt heating zones to different cookware is improved, but the complexity of managing heating zones and resetting parameters increases
Solution Approach 1:
The heating zone configuration is made dynamic by automatically tracking and following the cookware element when it is moved across the cooktop surface. The control system continuously updates the active heating elements based on the detected cookware position, transforming the static heating zone management into a dynamic adaptive system that automatically adjusts to cookware repositioning.
Solution Approach 2:
The system performs self-service by automatically detecting cookware position changes and autonomously reconfiguring the heating zones without requiring user intervention. The control unit monitors the cookware element through the detection arrangement and independently manages the heating element associations, eliminating the need for manual parameter resetting.
2Ease of operation
If the cooktop automatically associates heating elements with cookware, then the ease of operation is improved, but the loss of time for detecting and interpreting cookware movement processes increases
Solution Approach 1:
The system performs preliminary action by continuously monitoring the cooktop surface with the detection arrangement even before cookware is placed or moved. This continuous pre-detection capability allows the system to immediately recognize and respond to cookware positioning events without delay, reducing the time loss associated with detecting movement processes.
Solution Approach 2:
The detection arrangement provides continuous feedback about the cookware element's position and presence on the cooktop surface. This real-time feedback loop enables the control unit to rapidly detect and interpret cookware movement processes, minimizing detection time while maintaining accurate automatic association of heating elements with the cookware.
3Measurement precision
If the control unit interprets cookware removal and placement as separate processes, then the measurement precision is improved, but the ease of operation deteriorates due to requiring manual parameter resetting
Solution Approach 1:
The control unit merges the detection and interpretation of cookware removal and placement events into a unified continuous process. By treating the cookware movement as a single coherent event rather than separate discrete actions, the system maintains cooking parameter continuity and automatically carries over settings like target temperature, eliminating the need for manual resetting while preserving accurate process detection.

AI summary
In a method for operating a cooktop, a process of removal and placement of a cookware element with respect to a starting position and an end position is detectable by a detection arrangement. A control unit forms a heating zone to match a detected cookware element. The process can be independently associated by the control unit in one of two ways, a first way in which the process involves a movement of cookware element from the starting position into the end position and a movement of the heating zone into an area of the end position, with a target temperature, set by a user interface, being carried over to the area of the end position, a second way in which the process involves removal of cookware element from the starting position and placement of another cookware element in the end position, with a target temperature set to a default value.
