Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single power supply unit is shared between induction coil and power supply coil, then device complexity is reduced, but induction heating and wireless power transmission cannot be simultaneously executed
Solution Approach 1:
The patent divides the power supply system into separate inverter circuits: a first inverter circuit for the induction coil and a second inverter circuit for the power supply coil. This segmentation allows independent control and simultaneous operation of induction heating and wireless power transmission functions.
Solution Approach 2:
The patent implements dynamic control through a control unit that can independently regulate the first and second inverter circuits. This enables flexible switching between different operating modes (induction heating only, wireless power transmission only, or both simultaneously) based on real-time requirements.
2Device complexity
If induction coil and power supply coil are connected in series to a single power supply unit, then device complexity is reduced, but independent control of induction heating and wireless power transmission is lost
Solution Approach 1:
The patent separates the circuit into two independent parallel branches: one branch containing the induction coil driven by the first inverter circuit, and another branch containing the power supply coil driven by the second inverter circuit. This segmentation enables independent control of each function while maintaining a relatively simple overall structure.
Solution Approach 2:
The patent designs a control unit that can universally manage both inverter circuits, allowing the system to perform multiple functions (induction heating, wireless power transmission, or both) through a single integrated control interface, improving ease of operation.
3Ease of manufacture
If a single power supply unit is used for both induction coil and power supply coil, then manufacturing cost is reduced, but functional versatility is limited
Solution Approach 1:
The patent implements separate inverter circuits for the induction coil and power supply coil, which can be manufactured as modular units. This segmentation allows for standardized production of each module while enabling versatile system configurations, balancing manufacturing ease with functional adaptability.
Solution Approach 2:
The patent employs a dynamically controllable system where the control unit can independently adjust the operation of both inverter circuits. This provides cooking mode flexibility (induction only, wireless transmission only, or combined mode) while maintaining a manufacturing-friendly modular architecture.
