Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing temperature limiting devices are used, then safety function is improved, but they limit cooking zone temperature instead of container temperature
Solution Approach 1:
The patent uses a magnet as an intermediary that bridges the cooking zone and the detection means. The magnet is positioned in the cooking zone near the container, and when the insert reaches Curie temperature, the magnet detects the magnetic state change and triggers the detection means to cut off heating, ensuring the container temperature is directly monitored.
Solution Approach 2:
The patent implements a feedback mechanism where the detection means continuously monitors the magnetic state of the insert through the magnet and provides real-time feedback to the control system. When the insert reaches Curie temperature, the feedback signal triggers heating cutoff, ensuring precise temperature control based on actual container temperature.
2Measurement precision
If a movable magnet with detection means is added to the heating device, then temperature control precision is improved, but device complexity increases
Solution Approach 1:
The patent extracts the complex detection and control functions from the heating device structure and places them in a separate detection device. The heating device only needs to provide a magnet in the cooking zone, while the detection means with sensor and control circuitry are separate, reducing the complexity of the heating device itself.
Solution Approach 2:
The patent enables the system to self-regulate temperature automatically. The detection means automatically detects when the insert reaches Curie temperature through the magnet and automatically cuts off heating, eliminating the need for manual temperature monitoring and control by the user.
