Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a processing component is incorporated in each sensor, then sensitivity and reliability are enhanced, but device complexity increases
Solution Approach 1:
The system is divided into independent sensor nodes, each with its own processing component. This segmentation allows localized processing and calibration without affecting other sensors, improving reliability while keeping individual sensor complexity manageable through modular design
Solution Approach 2:
The processing component in each sensor is designed to be universal, capable of performing multiple functions including local data processing, calibration, and communication. This multi-functionality reduces the need for separate dedicated components, thereby enhancing reliability without proportionally increasing complexity
2Ease of operation
If remote calibration capability is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
Each sensor is equipped with its own processing component that enables self-calibration through local algorithms. The sensor can autonomously adjust its sensitivity and detection thresholds without requiring manual intervention or complex external calibration equipment, thereby improving ease of operation while minimizing the addition of external complexity
Solution Approach 2:
The processing component implements feedback mechanisms that allow the sensor to continuously monitor its own performance and automatically adjust calibration parameters. This closed-loop feedback enables remote calibration through software updates or control signals, improving operational ease without requiring physical access or complex calibration hardware
3Adaptability or versatility
If multiple detection technologies are integrated over a single communication line, then adaptability is improved, but device complexity increases
Solution Approach 1:
The processing component in each sensor is designed with universal interfaces and protocols that enable it to integrate multiple detection technologies (vibration, tension, acoustic, etc.) through a single communication line. The sensor can switch between or combine different sensing modes as needed, improving adaptability while maintaining communication simplicity through standardized data formats
Solution Approach 2:
Multiple detection technologies are merged into a unified sensor node with a single communication interface. The processing component consolidates data from various sensors (vibration, tension, acoustic) and transmits them through one communication line, reducing the complexity of the communication infrastructure while enhancing the system's ability to detect diverse intrusion methods

Implementation Method 1
sensing via the array, of one or more occurrence/s (or in other words—typical phenomena), that takes place when there is an attempted penetration through the physical barrier means
Implementation Method 2
variations in the tension of the wires, that naturally accompanies cutting, sawing of—or climbing on—the taut stretched wires

AI summary
An intrusion detection system, that comprises a multi sensors array deployable along a physical barrier means and linkable to it in a manner that enables sensing various phenomena (one or more), typically take place when an attempted intrusion act occurs through the physical barrier means, and generation of an indication when such a phenomenon is sensed, characterized by that, that at least in one of the sensors there is installed a processing component that belongs and is specifically allocated to the sensor and enables local analyzing of the sensed phenomena within said sensor.
