Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an RFID system is used to detect the presence of the insulating base, then the detection function is provided, but the heat resistance is insufficient and positioning precision is low
Solution Approach 1:
The patent replaces the RFID electromagnetic detection system with an optical sensor system that uses light to detect the presence of the insulating base. The optical sensor unit emits light through the insulating base and detects the reflected or transmitted light, providing reliable detection without exposing electronic components to high temperatures. This substitution of detection mechanism resolves the heat resistance issue while maintaining detection functionality.
Solution Approach 2:
The patent introduces an optical intermediary (light) as the detection medium between the sensor and the insulating base. Instead of using RFID electromagnetic fields that require heat-resistant electronics, the system uses optical signals that can be transmitted through the insulating base material itself, serving as both the detection medium and the thermal insulation barrier.

3Loss of energy
If thermal insulation is provided between the mounting plate and food receiving element, then heat transfer losses are reduced, but the complexity of the system increases
Solution Approach 1:
The patent merges the thermal insulation function with the detection function by integrating the optical sensor unit into the insulating base structure. The insulating base serves dual purposes: providing thermal insulation between the mounting plate and food receiving element, and housing the optical sensor that detects its presence. This integration reduces system complexity by combining multiple functions into a single component.
Solution Approach 2:
The insulating base is designed with multi-functionality, serving both as a thermal insulation barrier and as a carrier for the optical detection system. The optical sensor unit integrated into the insulating base performs detection while the insulating material provides thermal protection, allowing a single component to fulfill multiple roles and reduce overall system complexity.
