Existing food processors face challenges in achieving reproducible cooking results due to discrepancies in temperature control caused by environmental conditions and the complexity of heating power control during the boiling process.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If temperature control is performed by adjusting electrical energy based on actual temperature to reach desired temperature, then temperature accuracy is improved, but system complexity increases due to continuous monitoring and adjustment requirements
Solution Approach 1:
The cooking process is segmented into distinct phases: heating phase with dynamic temperature control and boiling phase with fixed energy supply. This segmentation allows the system to use complex control only when necessary (during heating) and switch to simple fixed control during the boiling stage, reducing overall system complexity while maintaining temperature accuracy during critical phases.
Solution Approach 2:
The control parameter changes from dynamic adjustment based on temperature feedback to fixed energy supply once boiling is detected. This parameter change simplifies the control system by eliminating continuous monitoring and adjustment requirements during the boiling stage, while maintaining temperature accuracy during the heating phase when it is most critical.
2Device complexity
If fixed energy supply is used after boiling detection, then system complexity is reduced, but temperature control accuracy deteriorates under varying environmental conditions
Solution Approach 1:
The system performs preliminary temperature control to reach the boiling stage with high accuracy before switching to fixed energy supply. This preliminary action ensures that the cooking process starts with accurate temperature control, and the fixed energy supply mode maintains consistency from that point onward, compensating for environmental variations through the established boiling point.
Solution Approach 2:
The system replaces continuous mechanical temperature control with a detection-based approach. Once boiling is detected, the system substitutes active temperature regulation with passive fixed energy supply, relying on the physical property of boiling point to maintain cooking accuracy without complex control mechanisms.
3Reliability
If continuous temperature monitoring and adjustment is performed, then cooking result consistency is improved, but energy consumption increases
Solution Approach 1:
The energy consumption is segmented into two phases: high energy input during heating to reach boiling with continuous monitoring, and fixed energy supply during boiling stage. This segmentation reduces total energy consumption by eliminating unnecessary continuous adjustment during the boiling phase, while maintaining cooking consistency through the initial accurate heating phase.
Solution Approach 2:
The system maintains continuous useful action during the heating phase to ensure accurate temperature control and cooking consistency, then transitions to fixed energy supply during boiling where continuous adjustment is less critical. This approach maintains cooking reliability while reducing energy waste from excessive monitoring and adjustment during less critical phases.
