Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional indicator and control circuit are installed in the cooktop, then the operation state can be indicated, but the internal structure becomes complicated
Solution Approach 1:
The patent extracts the indicator function from the main cooktop structure by using a separate wireless indicator device that communicates with the cooktop via wireless communication. This removes the need for physical indicator components and control circuits from the cooktop's internal structure, thereby reducing complexity while maintaining the operation state indication function.
Solution Approach 2:
The patent introduces a wireless communication module as an intermediary between the cooktop and the indicator. Instead of direct electrical connection and control, the cooktop and indicator communicate wirelessly, eliminating the need for complex internal circuitry while preserving the indication function.
2Reliability
If an indicator circuit is installed inside the cooktop, then the operation state can be displayed, but energy efficiency decreases
Solution Approach 1:
The patent extracts the indicator power consumption from the cooktop system by using a wireless indicator that operates independently. The indicator receives power through wireless energy transfer or uses its own power source, eliminating the energy waste associated with maintaining indicator circuits within the cooktop's power system.
Solution Approach 2:
The wireless indicator serves itself by using wireless communication to receive operation state data from the cooktop without requiring dedicated power supply circuits or control logic within the cooktop. This self-service approach minimizes the energy burden on the cooktop system.

Implementation Method 2
Magnetic lines of force generated from the working coil or the heating coil form eddy currents when passing through a cooking vessel. Therefore, as the eddy current flows through the cooking container, heat is generated
Implementation Method 3
as the eddy current flows through the cooking container, heat is generated to heat the cooking container itself
