Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple burners are used simultaneously in an induction cooking apparatus, then the cooking capacity is improved, but the power output is limited due to fixed power supply allocation
Solution Approach 1:
The patent implements dynamic power supply allocation by using a switching circuit to selectively connect different phases of the power supply to different heating coils based on real-time power consumption demands. This dynamic reconfiguration allows the system to adapt power distribution to match the actual cooking requirements of multiple burners, resolving the contradiction between cooking capacity and power output.
Solution Approach 2:
The system changes the parameter of power supply phase allocation by detecting the power consumption of each heating coil and switching between different phase configurations. This parameter change enables the apparatus to optimize power distribution across multiple burners, ensuring sufficient power output even when multiple burners operate simultaneously.
2Device complexity
If fixed power supply allocation is used, then the device complexity is reduced, but the cooking performance deteriorates when multiple burners are used
Solution Approach 1:
The patent incorporates a feedback mechanism where the controller detects the power consumption of each heating coil and uses this information to control the switching circuit. This feedback loop enables the system to automatically adjust power supply allocation based on actual cooking demands, maintaining high cooking performance without requiring overly complex manual configuration systems.
Solution Approach 2:
The system performs self-service by automatically detecting power consumption levels and switching power supply phases without user intervention. The controller monitors each heating coil's power consumption and autonomously configures the optimal power distribution, reducing device complexity while maintaining reliable cooking performance across multiple burners.
3Loss of energy
If multiple phases of power supply are selectively provided to heating coils, then the power distribution efficiency is improved, but the device complexity increases due to switching circuits and control mechanisms
Solution Approach 1:
The controller serves multiple functions by simultaneously detecting power consumption of heating coils, determining optimal phase allocation, and controlling the switching circuit. This multi-functionality reduces the need for separate dedicated components for each function, thereby improving power distribution efficiency while minimizing the increase in device complexity.
