Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple systems are employed to detect different gas properties and fire detection purposes, then detection capability is improved, but device complexity and installation cost increase
Solution Approach 1:
The aspirating detection system is designed to perform multiple detection functions (smoke detection, gas leak detection, carbon monoxide detection, and other industrial substance detection) using a single integrated system with a common network of pipes and a single centralised detection location, eliminating the need for multiple separate systems
2Adaptability or versatility
If multiple piping systems and detection units are installed within a building, then detection coverage is improved, but installation and maintenance cost increase
Solution Approach 1:
A single network of pipes is used to transport air samples from multiple sampling locations throughout the building to the centralised detection location, enabling comprehensive detection coverage without requiring multiple separate piping systems
Solution Approach 2:
The system allows flexible configuration of sampling locations along the pipe network, enabling detection coverage to be segmented into different zones while using a single integrated piping infrastructure
3Reliability
If multiple detection units are installed at separate locations, then detection reliability is improved, but monitoring complexity increases
Solution Approach 1:
Multiple detection functions and sampling locations are merged into a single centralised detection location where all air samples are analyzed using one control panel and alarm system, maintaining detection reliability while simplifying monitoring
