Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If only video cameras are used for surveillance, then the system structure is simple, but the detection capability is insufficient for events like fires or gas leaks
Solution Approach 1:
The patent combines multiple types of sensors (video cameras, audio sensors, smell sensors, taste sensors, tactile sensors) into a unified surveillance system. This merging of different sensing modalities enables comprehensive detection of various events including fires, gas leaks, and other environmental anomalies that single-sensor systems cannot detect reliably.
Solution Approach 2:
The surveillance system is designed to perform multiple detection functions simultaneously using different sensor types. Video cameras capture visual information, audio sensors detect sounds, smell sensors identify chemical compositions, taste sensors detect airborne particles, and tactile sensors sense physical conditions. This multi-functional approach allows a single system to handle diverse surveillance requirements.
2Reliability
If multiple sensors are integrated for comprehensive monitoring, then the detection capability improves, but the device complexity increases
Solution Approach 1:
The patent segments the complex surveillance system into distinct functional modules, each responsible for processing data from specific sensor types. The computing device separately processes video data, audio data, smell data, taste data, and tactile data before integrating the results. This segmentation manages complexity by organizing multiple sensors into manageable, independent processing streams.
Solution Approach 2:
The computing device acts as an intermediary that receives data from multiple sensor types, processes each data stream independently, and integrates the results to generate comprehensive environmental information. This intermediary processing layer manages the complexity of multi-sensor integration by providing a centralized coordination point.
3Productivity
If video data is manually retrieved and inspected, then complete analysis is possible, but time consumption and human resources increase
Solution Approach 1:
The surveillance system performs automatic event detection and analysis without requiring manual video retrieval and inspection. The computing device autonomously processes sensor data, identifies events of interest, and generates alerts. This self-service capability eliminates the need for human operators to manually review video footage, significantly reducing time consumption and human resource requirements.
Solution Approach 2:
The patent replaces the mechanical process of manual video retrieval and human inspection with automated computational processing. The computing device uses algorithms to analyze sensor data, detect patterns, and identify events automatically, substituting human cognitive work with machine-based processing that is faster and more efficient.
4Adaptability or versatility
If single-type sensors are used, then the system is simple to operate, but the monitoring capability is limited
Solution Approach 1:
The surveillance system incorporates multiple sensor types that can detect various environmental conditions including visual changes, sounds, chemical compositions, airborne particles, and physical conditions. This multi-functional sensor array enables the system to adapt to diverse monitoring scenarios and detect a wide range of events using a unified operational interface.
