Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If traditional electric heating tube is used for heating, then heating can be achieved, but heating effect is low and pre-heating time is long
Solution Approach 1:
The patent replaces traditional electric heating tubes with electromagnetic induction heating technology. The induction heating component generates an electromagnetic field that directly induces eddy currents in the pan, heating the pan and food rapidly without the need for thermal conduction through a heating element, thereby significantly reducing pre-heating time and improving heating efficiency.
Solution Approach 2:
The patent utilizes electromagnetic field phase transitions and energy conversion. The electromagnetic induction component converts electrical energy to electromagnetic energy, which then induces eddy currents in the pan, transforming electromagnetic energy into thermal energy directly in the pan, achieving rapid and efficient heating.
2Reliability
If heating board is made by low thermal conduction material such as crystallite glass, then safety and aesthetics are improved, but temperature detecting precision deteriorates
Solution Approach 1:
The patent extracts the temperature detection function from the heating board structure and places it on the operation panel. The temperature detecting component is positioned to detect temperature through the heating board without requiring the board itself to be thermally conductive, thus maintaining both safety benefits of low thermal conduction materials and accurate temperature detection.
Solution Approach 2:
The patent introduces an intermediary detection mechanism where the temperature detecting component measures temperature through the heating board material rather than requiring direct contact with the food or pan. This allows accurate temperature sensing while maintaining the safety advantages of low thermal conduction materials like crystallite glass.
3Adaptability or versatility
If double heating surfaces are equipped with separate heating devices and operational devices, then cooking versatility is improved, but operational complexity increases
Solution Approach 1:
The patent merges the control functions for both heating surfaces into a single shared operational device and control system. The heating devices for both surfaces can be independently controlled through one unified operation panel, allowing versatile cooking operations while simplifying the user interface and reducing operational complexity compared to having separate controls for each surface.
Solution Approach 2:
The patent implements a universal operational device that can control multiple heating functions. The single operation panel provides access to both heating surfaces, allowing the user to perform different cooking tasks (simmering, quick cooking, dual-surface heating) through one integrated control system rather than requiring separate devices for each function.
4Power
If pans are heated by heat conduction or heat radiation of electric tube, then heating can be achieved, but pans are easy to be distorted and heating uniformity deteriorates
Solution Approach 1:
The patent replaces contact-based heating (heat conduction through electric tubes or heating elements) with non-contact electromagnetic induction heating. The induction heating component generates an electromagnetic field that induces eddy currents directly in the pan, heating the pan uniformly from the inside without physical contact, thereby preventing pan distortion and ensuring uniform heating.
