Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If large numbers of sensors or fixed camera systems are installed throughout a facility, then temperature monitoring coverage is improved, but infrastructure investment cost increases significantly
Solution Approach 1:
The portable imaging system enables users to independently perform temperature inspections without requiring installation of fixed infrastructure. The system captures thermal images, tracks position data, and automatically compares temperatures with historical data, allowing facilities to conduct comprehensive monitoring using a single portable device rather than multiple fixed sensors throughout the facility.
2Device complexity
If manual inspection methods are used, then infrastructure cost is reduced, but human error increases due to reliance on user memory and manual recording
Solution Approach 1:
The system automatically compares captured thermal images with historical temperature data and provides real-time feedback to the user. The processor analyzes temperature differences and notifies the user when assets exceed predetermined thresholds, eliminating the need for manual recording and reducing human error through automated analysis and comparison with historical baselines.
Solution Approach 2:
The system replaces manual inspection processes with automated thermal imaging and data processing. Instead of relying on human operators to visually inspect, record, and analyze temperature data, the portable system automatically captures thermal images, processes the data, compares it with historical records, and generates notifications, thereby eliminating human error in data collection and analysis.
3Ease of operation
If thermal images are captured at inconsistent locations, then portability is maintained, but reliability of historical temperature comparisons deteriorates
Solution Approach 1:
The system adds a spatial dimension to temperature monitoring by incorporating position tracking capabilities. The processor receives position data from position sensors and uses this information to ensure thermal images are captured at consistent locations relative to assets. This positional context allows reliable comparison of historical temperature data even when using a portable device, as the system can verify that images were taken from the correct vantage points.
