Solution Overview
Problem
Existing hob devices lack intuitive operation and require multiple controls, making them complex and difficult to use, especially when dealing with variable cooking surfaces and multiple cooking zones.
Innovation Solution
A hob device with a variable cooking surface and control unit featuring multiple rotary controls, a sensor unit for detecting cooking utensils, and a control unit that adjusts heating elements based on inputs, along with an indication unit for assigning controls to cooking zones, providing intuitive operation and reducing the number of controls needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple controls are provided for each cooking zone, then precise control of heating elements is achieved, but device complexity and difficulty of operation increase
Solution Approach 1:
A single rotary control is designed to perform multiple functions: selecting different cooking zones, adjusting heating power levels, and controlling different cooking modes. This multi-functional design eliminates the need for separate controls for each function, reducing the total number of controls while maintaining comprehensive control capability over all cooking zones and parameters.
Solution Approach 2:
Multiple control functions that were previously distributed across separate controls are merged into a single rotary control interface. The rotary control integrates zone selection, power adjustment, and mode switching capabilities, consolidating what would have been multiple separate controls into one unified interface, thereby simplifying the overall device complexity.
2Adaptability or versatility
If fixed cooking zones are provided, then control structure is simplified, but adaptability to different cooking utensils is reduced
Solution Approach 1:
The cooking zones are designed to be dynamically adjustable rather than fixed. The system can change the number, position, and configuration of active cooking zones based on real-time detection of cooking utensils and user input. This dynamic adaptability allows the hob to accommodate various utensil sizes and shapes while maintaining a relatively simple control structure through automated zone management.
Solution Approach 2:
The system automatically detects the presence, position, and size of cooking utensils on the hob surface and autonomously configures the appropriate cooking zones without requiring manual intervention. This self-service capability enables the system to adapt to different utensils while keeping the control structure simple, as the automation handles the complexity of zone configuration internally.
3Productivity
If manual control assignment is required, then control precision is improved, but operation time and user effort increase
Solution Approach 1:
The system automatically assigns rotary control to cooking zones based on detected utensil positions and cooking requirements, eliminating the need for manual control assignment by the user. This automated assignment process reduces both the time and effort required for operation, while still achieving precise control through the systematic allocation of controls to appropriate zones.
Solution Approach 2:
The system performs preliminary automatic control assignment based on pre-determined criteria such as utensil detection results and cooking mode selections. By pre-configuring control assignments before the user needs to operate the hob, the system eliminates the need for time-consuming manual assignment while maintaining optimal control precision for each cooking zone.

AI summary
The device (10a) has a control unit (18a) for controlling a variable cooking surface (14a) based on inputs via an operating unit (20a). The operating unit is provided with control dials (22a, 24a, 26a, 28a) i.e. virtual control dials. The control unit changes a heating power of cooking zones (42a, 44a) of the variable cooking surface based on inputs via the control dials. An indication unit (30a) displays association of the control dials to the cooking zones. An associating unit (50a) performs an association between the control dials and the cooking zones based on operator inputs. An independent claim is also included for a method for operating a hob device.
