Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a particle sensor is used to detect vaporized aerosols, then detection capability is improved, but power consumption increases
Solution Approach 1:
The particle sensor operates in dynamic modes, switching between active detection and low-power states based on environmental conditions and detection needs, allowing the system to maintain detection capability while reducing average power consumption
Solution Approach 2:
The sensor employs periodic sampling rather than continuous monitoring, activating detection at intervals to maintain aerosol detection capability while significantly reducing overall power consumption during operation
2Measurement precision
If multiple sensors and camera units are deployed, then detection accuracy and monitoring coverage are improved, but device complexity increases
Solution Approach 1:
The system is divided into modular detection units, each with integrated sensors and processing capabilities, allowing distributed deployment that improves coverage and accuracy while keeping individual unit complexity manageable
Solution Approach 2:
Detection units are designed with multi-functional capabilities, combining particle sensing, video monitoring, and communication functions in single integrated modules, reducing overall system complexity despite multiple deployment points
3Loss of information
If real-time video monitoring is implemented, then monitoring capability is improved, but data processing requirements and energy consumption increase
Solution Approach 1:
Video data processing is extracted from the detection units and performed remotely on servers or cloud platforms, allowing local units to maintain simple processing while achieving comprehensive monitoring capabilities through centralized analysis
Solution Approach 2:
A communication network acts as an intermediary between detection units and processing systems, enabling real-time video monitoring while separating the energy-intensive processing functions from the field deployment locations
