Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional grills use simple thermometers, then the device complexity is low, but the measurement precision is insufficient and the thermometer cannot be seen in low light
Solution Approach 1:
The patent combines multiple temperature sensing probes (internal probe, food probe, ambient probe) with a microcontroller, LCD display, and control circuitry into an integrated temperature control system. This merging allows precise temperature measurement and control while maintaining a unified, manageable device structure that doesn't excessively increase complexity.
Solution Approach 2:
The patent replaces conventional mechanical thermometers with electronic temperature sensing probes and a digital microcontroller-based control system. This substitution enables precise temperature measurement with digital display, solving the visibility issue in low light while achieving accurate temperature control through electronic rather than mechanical means.
2Reliability
If no temperature monitoring is used, then the device complexity is low, but the food state cannot be accurately grasped leading to burnt or undercooked food
Solution Approach 1:
The patent implements a feedback control system where temperature sensing probes continuously monitor the internal grill temperature and food temperature, and the microcontroller adjusts the heating element based on this feedback to maintain the desired temperature. This ensures reliable cooking quality by preventing both burnt and undercooked conditions through active temperature regulation.
Solution Approach 2:
The temperature control system serves multiple functions: monitoring internal grill temperature, monitoring food temperature, displaying temperature readings on LCD, and automatically controlling the heating element. This multi-functionality achieves reliable cooking quality while keeping the device structure integrated and manageable.
3Measurement precision
If commercial grill probes are used, then the measurement precision is high, but the cost is too expensive to be popularized
Solution Approach 1:
The patent employs inexpensive temperature sensing probes and a cost-effective microcontroller-based control system that can be mass-produced at low cost. This approach achieves sufficient measurement precision for cooking applications while maintaining affordability for widespread adoption, unlike expensive commercial grill probes.
Solution Approach 2:
The patent uses multiple temperature sensing probes that can be manufactured using standard, inexpensive components rather than proprietary expensive sensors. By implementing the control logic in a microcontroller, the system achieves commercial-grade temperature control precision at a fraction of the cost of commercial probes.
