Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an integral structure is adopted with a connecting wire between upper cover and power source, then electrical functions can be performed, but the upper cover cannot be disassembled and is hard to be cleaned
Solution Approach 1:
The electric cooking pot is divided into separable components: the upper cover assembly and the pot body assembly. The upper cover can be detached from the pot body, allowing independent cleaning and maintenance of each component while maintaining electrical functionality through wireless power and communication circuits.
2Ease of operation
If a separated structure is adopted allowing upper cover disassembly, then cleanability is improved, but electrical functions cannot be performed by the upper cover since it cannot couple with the power source
Solution Approach 1:
The mechanical connecting wire system is replaced with wireless electromagnetic induction power transmission and coil coupling communication systems. This allows the upper cover to perform electrical functions without physical connection to the power source, enabling both disassembly for cleaning and reliable electrical operation.
3Adaptability or versatility
If wireless power and signal transmission is implemented between separated upper cover and pot body, then cleanability and electrical function are both improved, but simultaneous wireless power supply and communication is challenging to achieve
Solution Approach 1:
The wireless communication circuit utilizes the electromagnetic induction coil system to perform multiple functions: power transmission, signal communication, and amplitude modulation for data encoding. This multi-functional approach enables simultaneous wireless power supply and communication without requiring separate dedicated systems, reducing overall circuit complexity.
