Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sensor unit inside the cooking chamber detects temperature, then the cooking process can be monitored, but the sensor cannot directly detect muffle wall temperature for precise overheating prevention
Solution Approach 1:
The patent introduces a second sensor unit as an intermediary device that directly contacts the muffle wall to detect its temperature. This mediator sensor provides accurate muffle wall temperature data to the control unit, enabling precise overheating prevention while the first sensor unit continues to monitor cooking chamber temperature for cooking process control.
2Productivity
If the heating element continuously heats the muffle wall, then cooking efficiency is improved, but overheating and damage to the muffle wall may occur
Solution Approach 1:
The patent implements a feedback control system where the second sensor unit continuously monitors muffle wall temperature and feeds this information back to the control unit. The control unit adjusts the heating element's operation based on this feedback, reducing or stopping heating when the muffle wall approaches dangerous temperatures, thus preventing overheating while maintaining cooking efficiency.
3Measurement precision
If multiple sensor units are added to detect both muffle wall temperature and cooking chamber temperature, then temperature control is improved, but device complexity increases
Solution Approach 1:
The control unit is designed with multi-functionality to handle data from both sensor units. It simultaneously processes cooking chamber temperature data for cooking process control and muffle wall temperature data for overheating prevention, integrating multiple functions into a single control system to minimize overall device complexity.
