Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aspiration smoke detection systems face challenges in accurately identifying the location and timing of air particulate generation due to the length of pipe runs, which delays detection and makes it difficult to pinpoint the source of smoke or particles.
Innovation Solution
The system employs a secondary particulate detector located proximate to sampling points, utilizing optical scattering to identify air particulates and transmit this information wirelessly to an aspiration detection system, allowing for rapid identification of particulate location and type, and activating alarms accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If air particulates are transported through long pipe runs to a centralized detection chamber, then the system can cover large detection areas with multiple sampling points, but the detection time increases and the source location cannot be accurately determined
Solution Approach 1:
The system divides the detection network into multiple independent detection zones, each with its own secondary particulate detector positioned near sampling points. This segmentation allows simultaneous detection across multiple locations without requiring long pipe runs to a single centralized chamber, thereby maintaining wide coverage while reducing detection time and enabling precise source localization.
2Area of stationary object
If air particulates are transported through long pipe runs to a centralized detection chamber, then the system can cover large detection areas, but the physical source location of smoke remains unknown
Solution Approach 1:
Secondary particulate detectors act as intermediaries positioned near sampling points throughout the detection area. These intermediaries perform initial detection and identification of air particulates at or near their source, then transmit data to the centralized aspiration detection system. This intermediary approach preserves source location information while still enabling centralized processing and wide-area coverage.
3Loss of time
If secondary particulate detectors are located proximate to sampling points, then detection time is reduced and source location is identified, but the system complexity increases
Solution Approach 1:
The system replaces complex mechanical transport infrastructure with simpler wireless communication links. Secondary particulate detectors positioned near sampling points use wireless transmitters to send data to the centralized system, eliminating the need for extensive pipe networks connecting all sampling points to individual detectors. This substitution reduces mechanical complexity while achieving rapid detection and source identification.
