Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple sensors are deployed to improve target detection capability, then detection reliability is improved, but device complexity and cost increase
Solution Approach 1:
The patent combines multiple sensor types (acoustic, video, infrared, radar, LIDAR) into a single integrated sensor unit that captures multiple data modalities simultaneously. This merging approach improves detection reliability through multi-modal fusion while avoiding the complexity of coordinating multiple separate sensor systems, as all sensors are co-located and synchronized within one unit
Solution Approach 2:
The sensor unit is designed as a universal platform capable of performing multiple detection functions across different modalities (acoustic detection, visual recording, thermal sensing, radar detection). This multi-functional design consolidates what would otherwise require separate specialized sensor systems into a single versatile unit, improving reliability without proportionally increasing complexity
2Area of stationary object
If sensor coverage area is increased to monitor larger regions, then monitoring capability is improved, but sensor resolution and detection precision deteriorate
Solution Approach 1:
The monitoring system divides the large monitoring area into multiple overlapping fields of view from different sensor types and multiple sensor units. Each sensor captures data from its specific zone with high precision, and the system segments the overall monitoring task across multiple sensor perspectives, allowing both broad coverage and detailed precision through spatial segmentation
Solution Approach 2:
The patent transitions from two-dimensional planar monitoring to three-dimensional volumetric monitoring by incorporating sensors at different heights and orientations (including aerial drones and ground-based sensors). This dimensional expansion allows the system to cover larger areas while maintaining precision through vertical layering and multi-angle observation
3Measurement precision
If data processing complexity is increased to improve target identification accuracy, then detection precision is improved, but processing time and computational resources increase
Solution Approach 1:
The system performs preliminary data processing and feature extraction at the sensor level before data leaves the sensor unit. Basic filtering, noise reduction, and feature detection are executed locally in real-time, preprocessing the data to reduce its complexity before transmission to central processing systems. This preliminary action reduces the computational burden on central systems while maintaining identification accuracy
Solution Approach 2:
The patent introduces intermediate processing layers including edge computing devices and distributed processing nodes that act as mediators between sensors and central processing systems. These intermediaries perform partial data analysis and filtering, reducing the volume and complexity of data requiring full processing while preserving critical information needed for accurate target identification
