Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If nanofiber sensors are used to detect contaminants, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The sensor system is divided into multiple nanofiber sensors, each functionalized to detect specific types of contaminants (vapor, gas, or particulate matter). This segmentation allows the system to achieve high measurement precision for different contaminant types while maintaining manageable device complexity through modular architecture.
Solution Approach 2:
The nanofiber sensors act as intermediaries between the air sample and the detection system. These sensors are functionalized with specific materials that selectively interact with target contaminants, enabling precise detection while simplifying the overall system design by concentrating the detection function in the nanofiber component.
2Adaptability or versatility
If multiple sensor types are integrated to detect various contaminants, then adaptability is improved, but device complexity increases
Solution Approach 1:
The system employs multiple nanofiber sensors with different functionalizations, allowing a single sensor platform to detect various types of contaminants (vapors, gases, and particulates). This multi-functionality approach improves adaptability while avoiding the complexity of entirely separate detection systems for each contaminant type.
Solution Approach 2:
Each nanofiber sensor is locally functionalized with specific materials tailored to detect particular contaminant types. This local quality differentiation enables the system to handle diverse contaminants through specialized sensors rather than requiring a completely complex universal detection mechanism.
3Reliability
If real-time monitoring is implemented, then reliability is improved, but use of energy increases
Solution Approach 1:
The system implements continuous real-time monitoring of air quality through the nanofiber sensor array, ensuring reliable detection of contaminants at all times. The controller continuously processes sensor data and maintains system readiness, providing uninterrupted monitoring capability for enhanced reliability.
Solution Approach 2:
The controller receives continuous feedback from the nanofiber sensors and adjusts system responses accordingly. This feedback mechanism enables reliable real-time monitoring while optimizing energy usage by activating mitigation systems only when contaminants are detected, rather than operating continuously.
4Object-affected harmful factors
If ventilation and alert systems are activated upon detection, then harmful factors are reduced, but device complexity increases
Solution Approach 1:
The system converts the harmful presence of contaminants into a beneficial response by detecting contaminant levels and automatically activating ventilation or alert systems. This approach transforms the potential harm into a controlled situation where mitigation is triggered by the detection itself, reducing passenger exposure while maintaining relatively simple system architecture.
Solution Approach 2:
The system performs self-service by automatically detecting contaminants and activating appropriate mitigation measures without requiring manual intervention. The controller autonomously processes sensor data and triggers ventilation or alerts, reducing the need for complex manual control systems while effectively reducing harmful factors.
