Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If optical sensors are added to detect volatile compounds, then measurement precision of chemical substances is improved, but device complexity increases
Solution Approach 1:
The detector device is divided into separate functional modules: optical sensors for detecting volatile compounds, a control unit for processing sensor signals, and a communication unit for data transmission. This segmentation allows each module to perform its specific function efficiently while maintaining overall system manageability despite the increased complexity.
Solution Approach 2:
The control unit serves multiple functions: it processes signals from the optical sensors, analyzes detected volatile compound data, controls the heating element temperature, and manages communication with external devices. This multi-functionality reduces the need for separate dedicated components, thereby limiting the increase in device complexity.
2Reliability
If real-time detection of volatile compounds is implemented, then food preparation safety is improved, but energy consumption increases
Solution Approach 1:
The optical sensors and detection system operate periodically rather than continuously, scanning for volatile compounds at regular intervals during the cooking process. This periodic operation maintains real-time safety monitoring capability while significantly reducing energy consumption compared to continuous monitoring.
Solution Approach 2:
The control unit receives real-time feedback from the optical sensors about volatile compound levels and automatically adjusts heating element power accordingly. When dangerous levels of volatiles are detected, the system reduces heating power or shuts off the heater, preventing both safety hazards and unnecessary energy consumption from continued high-temperature heating.
