Solution Overview
Problem
Existing spark detectors in media-filled or media-flowing reservoirs struggle with unreliable detection and hazard assessment of ignition-causing phenomena due to absorption phenomena by the medium, leading to potential false alarms and increased risk of fires or explosions.
Innovation Solution
A system that analyzes ignition-relevant phenomena by detecting electromagnetic radiation absorption in two distinct wavelength ranges, using a measuring arrangement to determine absorption values and coefficients, and adjusts measurement sensitivity based on these values to improve detection accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single wavelength range is used for detection, then the device complexity is reduced, but the measurement precision deteriorates due to absorption phenomena
Solution Approach 1:
The measurement system is segmented into multiple detection channels, each sensitive to a specific wavelength range (e.g., visible light and infrared). This allows the system to measure absorption characteristics at different wavelengths independently, thereby improving measurement precision by accounting for absorption phenomena without requiring a single overly complex detection device.
Solution Approach 2:
The system transitions from single-parameter detection to multi-dimensional detection by measuring absorption at multiple wavelength ranges. This dimensional expansion in the measurement space enables the system to distinguish between absorption effects and actual ignition events, improving precision while maintaining manageable device complexity through modular detector design.
2Reliability
If absorption characteristics are not considered, then the ease of operation is improved, but the reliability deteriorates due to false alarms
Solution Approach 1:
The system performs preliminary measurement of absorption characteristics of the medium before conducting ignition detection. By pre-characterizing the absorption properties of the medium being conveyed, the system establishes baseline data that is automatically used during operation to distinguish true ignition events from absorption effects, thereby improving reliability without requiring complex real-time adjustments during operation.
Solution Approach 2:
The system incorporates feedback mechanisms where absorption measurements from multiple wavelength ranges are continuously monitored and used to adjust detection thresholds and algorithms. This feedback loop automatically compensates for absorption variations, improving reliability while maintaining ease of operation through automated rather than manual adjustment processes.
3Measurement precision
If multiple wavelength ranges are measured, then the measurement precision is improved, but the loss of time increases due to additional measurements
Solution Approach 1:
The system implements periodic measurement cycles where absorption characteristics are measured at multiple wavelength ranges in rapid succession rather than continuously. This periodic multi-wavelength measurement approach maintains measurement precision by regularly updating absorption data while minimizing time loss through efficient cycling between wavelength ranges rather than simultaneous continuous measurement.
Solution Approach 2:
The system measures absorption at multiple wavelength ranges but focuses computational resources on the most critical wavelength ranges for the specific application. By performing partial measurements at selected wavelengths rather than exhaustive measurement across all possible wavelengths, the system achieves sufficient measurement precision while reducing the time penalty associated with multi-wavelength detection.
