Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a primary power transmitting process and a secondary power transmitting process are used to heat the inner pot, then the inner pot can be heated through induction heating, but power loss occurs during the two power transmitting processes
Solution Approach 1:
The patent combines the primary power transmitting coil and secondary power transmitting coil into a single integrated heating coil structure. This merging eliminates the intermediate power transmission step, allowing direct power transmission from the power supply to the inner pot through one unified magnetic field generation system, thereby reducing power loss while maintaining effective heating capability.
2Adaptability or versatility
If electronic devices are built in the cooker, then the cooker functionality is enhanced, but the cooker cannot wirelessly receive power from the power supply
Solution Approach 1:
The heating coil serves multiple functions simultaneously: it acts as both the primary power transmitting coil for heating the inner pot and the secondary power receiving coil for wirelessly receiving power to operate electronic devices within the cooker. This multi-functional design enables the cooker to perform both heating operations and power wireless reception through a single integrated component.
3Productivity
If the cooker is placed on the induction heating device, then heating can be performed, but abnormal displacement leads to degraded performance and safety hazards
Solution Approach 1:
The system incorporates a displacement detection mechanism that continuously monitors the positional relationship between the cooker and the induction heating device. When abnormal displacement is detected, the system provides feedback to adjust the heating parameters or alert the user, ensuring safe operation and maintaining optimal heating performance throughout the cooking process.
