Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for operating household microwave appliances focus on detecting critical states of the microwave generator, such as idling or malfunction, and taking corrective measures, rather than utilizing the generator's temperature to optimize cooking performance and energy efficiency.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the microwave generator temperature is used to detect critical states (idling, malfunction) and take corrective measures, then the reliability of the microwave generator is improved, but the cooking performance and energy efficiency are not optimized
Solution Approach 1:
The patent segments the temperature-based control into two distinct functions: (1) monitoring critical states (idling, malfunction) for reliability protection, and (2) optimizing cooking performance by adjusting microwave parameters based on generator temperature. This segmentation allows both reliability and productivity goals to be achieved simultaneously through separate control mechanisms.
Solution Approach 2:
The patent implements dynamic adjustment of microwave treatment parameters (power level, treatment time, field distribution) based on real-time generator temperature measurements. The system transitions from static, fixed-parameter operation to dynamic, temperature-adaptive control, optimizing cooking performance while maintaining generator reliability through continuous parameter adjustment.
2Object-affected harmful factors
If the microwave generator temperature is monitored to avoid overheating and idling, then the safety of the appliance is improved, but the treatment duration and energy consumption are not reduced
Solution Approach 1:
The patent employs feedback control by continuously monitoring generator temperature and using this information to adjust microwave treatment parameters in real-time. The temperature measurement feeds back to the control system, which modifies power levels and treatment duration to optimize cooking while preventing overheating, thereby reducing overall treatment time without compromising safety.
Solution Approach 2:
The patent changes microwave treatment parameters (power level, time, field distribution) dynamically based on generator temperature conditions. By adjusting these parameters in response to temperature feedback, the system prevents overheating while optimizing treatment duration, achieving both safety and efficiency goals simultaneously.
3Ease of operation
If fixed microwave parameters are used for cooking operations, then the ease of operation is improved, but the energy efficiency and cooking optimization are reduced
Solution Approach 1:
The patent implements self-service control where the microwave system automatically adjusts its own parameters based on generator temperature without requiring user intervention. The system monitors its own thermal state and adapts cooking parameters autonomously, maintaining ease of operation while significantly improving energy efficiency through intelligent, temperature-driven parameter optimization.
