Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Induction hobs lack flexibility in usage, as existing technologies do not efficiently adapt to both fixed and adaptive heating zones, leading to increased production and storage costs due to the need for multiple communication bus systems and central controllers.
Innovation Solution
An induction module with a controller and communication interface that operates in master-slave configuration modes, allowing for software configuration as either a master or slave module, reducing the need for central controllers and enabling use in both fixed and adaptive heating zone configurations, using a single communication bus for all modules and the user interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple communication bus systems and central controllers are used to support both fixed and adaptive heating zones, then the induction hob can accommodate different heating zone configurations, but the device complexity and production costs increase
Solution Approach 1:
The induction module is designed with multi-functional capability to operate in different configuration modes (fixed heating zone mode and adaptive heating zone mode) using the same hardware platform. The module can function as either a master module or a slave module, eliminating the need for different hardware configurations and reducing device complexity while maintaining versatility.
Solution Approach 2:
The induction module employs dynamic configuration capabilities where the role assignment (master or slave) and operational mode can be changed through software settings rather than fixed hardware configurations. This dynamic adaptability allows the same module to serve different functions based on system requirements, reducing the need for multiple communication bus systems.
2Adaptability or versatility
If multiple communication bus systems and central controllers are used to support both fixed and adaptive heating zones, then the induction hob can accommodate different heating zone configurations, but production and storage costs increase
Solution Approach 1:
By designing a universal induction module that can operate in both fixed and adaptive heating zone configurations, the system eliminates the need to manufacture and store multiple specialized components. The same module design serves multiple purposes, reducing production complexity and inventory requirements.
Solution Approach 2:
The system uses software-based parameter changes to switch between different operational modes (fixed zone, adaptive zone, master module, slave module) rather than requiring different hardware configurations. This allows cost-effective mass production of standardized modules that can be programmed for different functions.
3Device complexity
If a single communication bus is used for all modules and the user interface, then the device complexity and production costs are reduced, but the communication management becomes more challenging
Solution Approach 1:
The communication management is segmented by assigning specific roles (master or slave) to different modules. The master module handles communication with the user interface and coordinates with slave modules, while slave modules communicate only with the master. This segmentation simplifies the overall communication architecture on a single bus by creating clear communication pathways and reducing management complexity.

Implementation Method 1
the induction coil is coupled with electronic driving means for driving an AC current through the induction coil. Said AC current generates a time varying magnetic field. Due to the inductive coupling between the induction coil and the piece of cookware placed above the induction coil, the magnetic field generated by the induction coil causes eddy currents circulating in the piece of cookware. The presence of said eddy currents generates heat within the piece of cookware due to the electrical resistance of said piece of cookware.
Implementation Method 2

AI summary
An induction module powers one or more induction coils. It includes an induction generator; a controller; and a communication interface for coupling with a user interface. The controller is adapted to operate the induction module according to first and a second configuration modes, wherein in the first configuration mode the induction module is configured to directly communicate with the user interface, and in the second configuration mode, the induction module is adapted to be operated either according to a master module or a slave module configuration. In the master module configuration, the induction module is configured to receive user interface information from the user interface and provide operation information to a slave induction module. In the slave module configuration, the induction module is configured to receive operation information from a master induction module and operate the induction generator according to that operation information.
