Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a dedicated heating device or cooking vessel with integrated temperature sensor is used for automatic cooking, then automatic cooking functionality is achieved, but device complexity and cost increase
Solution Approach 1:
A separate cooking appliance with temperature sensors acts as an intermediary between the user and the induction range. This intermediary device measures the temperature of general cooking vessels and communicates with the wireless power transmission device to enable automatic cooking control without requiring modifications to the vessel or range itself
Solution Approach 2:
The patent replaces the need for physical integration of sensors into cooking vessels with a wireless communication system. The cooking appliance uses temperature sensors and wireless communication to transmit cooking state information to the power transmission device, substituting mechanical integration with electronic/wireless communication
2Measurement precision
If multiple temperature sensors are used to improve temperature measurement accuracy, then measurement precision increases, but device complexity increases
Solution Approach 1:
The temperature measurement function is segmented across multiple independent temperature sensors positioned at different locations within the cooking appliance. Each sensor independently measures temperature at its specific position, and the cooking appliance processes these multiple measurements to determine overall cooking temperature and state
Solution Approach 2:
The multiple temperature sensors serve multiple functions: they monitor different regions of the cooking vessel, provide redundant measurement for accuracy, and enable detection of temperature gradients. This multi-functionality justifies the addition of multiple sensors without proportionally increasing complexity
