Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensors are installed in each fire compartment, then fire detection coverage is improved, but device complexity and installation cost increase
Solution Approach 1:
The patent combines multiple fire sensing functions into a single integrated sensor unit installed at the penetration part. This sensor detects fires in both adjacent fire compartments simultaneously, merging what would otherwise require separate detection systems into one unified device, thereby reducing overall system complexity while maintaining comprehensive coverage
Solution Approach 2:
The sensor installed at the penetration part serves multiple functions: it detects fires in the first fire compartment, detects fires in the second fire compartment, and provides information for calculating fire vector direction. This multi-functionality eliminates the need for separate sensors in each compartment, resolving the contradiction between coverage and complexity
2Productivity
If sensors are installed at penetration parts of fire walls, then real-time fire spread tracking is improved, but installation complexity increases
Solution Approach 1:
The system merges fire detection for multiple compartments into a single sensor installation location (the penetration part). This allows the sensor to monitor fire spread between compartments without requiring separate installations in each space, thereby maintaining high tracking productivity while simplifying the installation process
Solution Approach 2:
The penetration part of the fire wall serves as an intermediary location that provides access to both fire compartments. By installing the sensor at this intermediate position, the system can detect fires in both compartments without requiring complex installations deep within each compartment, thus improving ease of manufacture while maintaining tracking capability
3Measurement precision
If fire vector calculation is implemented, then fire spread direction accuracy is improved, but information processing complexity increases
Solution Approach 1:
The system uses feedback from the sensor data to calculate fire vector direction. By continuously monitoring fire detection signals and processing them through vector calculation algorithms, the system achieves high directional accuracy while the processing complexity remains manageable due to the straightforward mathematical relationships involved in vector analysis
