Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired connections are used for power transmission, then power supply reliability is improved, but portability and ease of operation deteriorate
Solution Approach 1:
The patent replaces the mechanical wired connection system with an electromagnetic induction system. The cooking accessory includes a receiver coil that wirelessly receives power from the induction cooktop through electromagnetic fields, eliminating the need for physical cable connections while maintaining reliable power transmission.
2Adaptability or versatility
If multiple heating devices are added to increase cooking zones, then cooking versatility is improved, but device complexity increases
Solution Approach 1:
The patent divides the heating system into multiple independent heating devices (first heating device and second heating device) that can operate independently. Each heating device has its own control circuitry, allowing separate temperature and power control for different cooking zones, thereby increasing versatility without creating a single complex control system.
Solution Approach 2:
The patent arranges heating devices in a vertical configuration (first heating device in a first support member, second heating device in a second support member above it). This vertical stacking utilizes the vertical dimension to create multiple cooking zones within a compact footprint, increasing cooking versatility without expanding horizontal space or control complexity.
3Ease of operation
If wireless power transfer is implemented, then portability is improved, but power transmission efficiency deteriorates
Solution Approach 1:
The patent extracts the power transmission function from the physical connection and implements it through electromagnetic induction. The receiver coil in the cooking accessory captures electromagnetic energy from the cooktop's transmitter coil, enabling wireless power transfer that maintains portability while achieving sufficient transmission efficiency for cooking applications.

AI summary
A cooking system includes a support structure that has a support surface and a cooking device for placement on the support structure. A power transmission circuit is between the support structure and the cooking device. The power transmission circuit has a first power communication coil in the support structure, a second power communication coil in the cooking device, and a power source that is in communication with the first power communication coil. The first power communication coil is configured to induce an electrical current in the second power communication coil. A heat control circuit has a first heating device and a second heating device in the cooking device. The second heating device is disposed above the first heating device. A controller is configured to control a power level for the first and second heating devices.
