Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing induction heating cooking apparatuses lack the ability to efficiently control and distribute heating current to specific areas of the cooking plate, limiting flexibility and precision in cooking vessel heating.
Innovation Solution
A cooking apparatus with a cooking plate divided into sub-areas, each with its own induction heating coil group, a user interface for inputting compartment commands, and a controller to distribute a preset target temperature current to the corresponding induction heating coil group, allowing for precise temperature control and flexible cooking area configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single induction heating coil is used for the entire cooking plate, then the device structure is simple, but the flexibility and precision in controlling heating areas is limited
Solution Approach 1:
The cooking plate is divided into multiple sub-areas, with each sub-area having its own independently controllable induction heating coil group. This segmentation allows users to activate only the heating zones needed for their cooking requirements, providing flexible cooking area configuration while maintaining a modular structure that balances complexity with functionality
Solution Approach 2:
The system dynamically configures active heating zones based on user input through the user interface. When a compartment command is received, the controller activates only the drive assemblies corresponding to the selected sub-areas, allowing the heating configuration to adapt dynamically to different cooking needs without requiring physical reconfiguration of the entire device
2Ease of operation
If drive assemblies are integrated with the cooking plate structure, then the device is more compact, but the ability to independently control specific coil groups is reduced
Solution Approach 1:
The control system is segmented into multiple independent drive assemblies, with each drive assembly responsible for controlling a specific induction heating coil group. This segmentation enables independent control of each heating zone through the user interface, allowing users to activate or deactivate specific sub-areas based on their cooking requirements
Solution Approach 2:
Each drive assembly is designed as a universal module capable of controlling its associated induction heating coil group independently. The user interface provides compartment commands that can selectively activate any combination of drive assemblies, making the system multi-functional and adaptable to various cooking scenarios while maintaining a standardized control architecture

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient and precise heating of cooking vessels by allowing users to divide the cooking area into sub-areas and select specific induction heating coil groups, increasing the degree of freedom in cooking vessel placement and usability.
Implementation Method 1
an induction heating coil to generate a magnetic field when a current is applied thereto. If the current is applied to the induction heating coil to generate a magnetic field, a secondary current is induced to the cooking vessel
Implementation Method 2
Joule heat is generated due to resistance components of the cooking vessel. Accordingly, the cooking vessel is heated by the Joule heat
Implementation Method 3
a plurality of induction heating coil groups installed at a bottom of the cooking plate so as to correspond to each of the plurality of sub-areas
