Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a primary power transmitting process between the heating power supply coil and the heating power receiving coil is used to heat the inner pot, then the inner pot can be heated, but power loss occurs during the power transmitting process
Solution Approach 1:
The patent merges the power transmission function and heating function into a single direct induction heating process. The heating power supply coil directly induces current in the inner pot through magnetic coupling, eliminating the intermediate heating power receiving coil and induction heating coil, thus reducing power loss while maintaining effective heating.
Solution Approach 2:
The heating power supply coil serves dual functions: it acts as both the power transmission element and the heating element. By generating a magnetic field that directly induces current in the inner pot, the same coil structure accomplishes both power delivery and heating, reducing the number of components and energy conversion steps.
2Temperature
If a secondary power transmitting process between the heating power receiving coil and the induction heating coil is used, then the inner pot can be heated, but additional power loss occurs during the second power transmitting process
Solution Approach 1:
The patent extracts and eliminates the intermediate heating power receiving coil and induction heating coil from the system. By using direct electromagnetic induction from the heating power supply coil to the inner pot, the patent removes the secondary power transmission stage that causes additional power loss, while maintaining the heating function.
3Productivity
If the wireless induction heating cooker is abnormally disposed on the induction heating device, then cooking performance degrades, but safety hazards may also occur
Solution Approach 1:
The patent implements a feedback mechanism where the induction heating device detects the displacement state of the wireless induction heating cooker through changes in magnetic coupling or electrical parameters. When abnormal displacement is detected, the system provides feedback to notify the user and adjusts the heating output accordingly, preventing both performance degradation and safety hazards.
Solution Approach 2:
The patent introduces dynamic adjustment of heating output based on the real-time displacement state of the cooker. The heating power supply coil's output is continuously adjusted according to the detected displacement, allowing the system to adapt to different cooking positions and maintain optimal performance while preventing safety issues.
