Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If additional sensors or components are added to detect boiling point, then boiling point detection capability is improved, but production effort and device complexity increase
Solution Approach 1:
The heating element serves dual functions: heating the food and acting as a temperature sensor through its electrical resistance measurements. The control device analyzes electrical measurement values (current, voltage, or power) to detect boiling point, eliminating the need for separate temperature sensing components during boiling detection.
Solution Approach 2:
The system uses its own existing components (heating element and control device) to perform the boiling point detection function. The heating element's electrical characteristics change naturally during boiling, and the control device leverages this self-generated information without requiring external sensors or additional hardware.
2Measurement precision
If additional sensors or components are added to detect boiling point, then boiling point detection capability is improved, but device complexity increases
Solution Approach 1:
The heating element serves dual functions: heating the food and acting as a temperature sensor through its electrical resistance measurements. The control device analyzes electrical measurement values (current, voltage, or power) to detect boiling point, eliminating the need for separate temperature sensing components during boiling detection.
Solution Approach 2:
The patent extracts the temperature sensing function from separate hardware components and integrates it into the existing heating element's electrical measurements. By taking out the need for additional sensors and using only the electrical characteristics of the heating element, the device complexity is reduced while maintaining boiling point detection capability.
3Measurement precision
If temperature is monitored continuously to detect boiling point, then cooking quality is improved, but energy consumption increases
Solution Approach 1:
The system continuously monitors the electrical measurement values of the heating element during the entire heating process, enabling continuous temperature monitoring without interruption. This continuous action provides accurate boiling point detection while using the same energy already dedicated to heating, avoiding additional energy consumption for separate sensing operations.
Solution Approach 2:
The heating element's electrical characteristics provide temperature information as a byproduct of the heating process itself. The control device extracts temperature data from the electrical measurement values without requiring additional energy input, as the thermal and electrical processes occur simultaneously using the same energy source.
