Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individual elevator control systems are used for earthquake monitoring, then elevator safety can be maintained, but the system cannot observe structural vibrations and regional impacts comprehensively
Solution Approach 1:
The system divides the monitoring function into multiple independent sensor terminals distributed throughout the structure, each measuring local vibrations. These segmented measurements are then aggregated to provide comprehensive structural monitoring without requiring a single complex centralized system.
Solution Approach 2:
The sensor terminals serve multiple functions: they measure vibration data, determine positions, and contribute to both individual structure monitoring and regional impact analysis. This multi-functionality expands the system's adaptability while maintaining relatively simple individual components.
2Loss of information
If multiple sensor terminals are deployed to monitor structural vibrations, then comprehensive observation of structural vibrations and regional impact is enabled, but the system complexity increases
Solution Approach 1:
The system merges data from multiple sensor terminals by synchronizing their measurements in time and combining the information to reconstruct comprehensive vibration patterns and propagation states across the entire structure and surrounding regions.
Solution Approach 2:
The display device acts as an intermediary that receives data from multiple sensor terminals, synchronizes the information, and generates visual representations. This intermediary function consolidates the complexity in a centralized processing unit while keeping individual sensor terminals simple.
3Measurement precision
If vibration data from multiple positions is collected and processed, then detailed analysis of vibration distribution and propagation is achieved, but the processing time and computational requirements increase
Solution Approach 1:
The system performs preliminary actions by pre-establishing the relationship between sensor positions and map locations, and by pre-processing raw vibration data into meaningful measurements. This preparation enables faster analysis during actual earthquake events.
Solution Approach 2:
The system creates a virtual copy of the physical structure represented on a map, overlaying vibration data onto this digital representation. This allows complex spatial analysis to be performed on the simplified digital model rather than requiring complex real-time analysis of actual structural data.
