Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a security monitoring network is constructed using modern technology, then intrusion detection capability is improved, but device complexity increases
Solution Approach 1:
The system segments intrusion detection into two distinct modes: security line detection and security area detection. Each mode operates independently with its own detection logic and alerting mechanism, allowing the system to handle different intrusion scenarios without increasing overall complexity. The segmentation enables modular implementation where each detection type can be optimized separately.
Solution Approach 2:
The patent transitions from traditional single-point detection to two-dimensional detection spaces (lines and areas). By defining intrusion not just at a point but along a line or within an area, the system captures more comprehensive security information while maintaining manageable computational complexity through geometric abstraction.
2Measurement precision
If intrusion detection accuracy is improved by analyzing multiple parameters, then measurement precision increases, but difficulty of detecting and measuring increases
Solution Approach 1:
The detection process is segmented into distinct stages: obtaining historical detection boxes, determining current detection box, checking intersection with security lines/areas, and generating alerts. Each stage handles a specific aspect of intrusion detection, making the overall complex process manageable through systematic breakdown.
Solution Approach 2:
The system performs preliminary actions by obtaining and storing historical detection boxes before actual intrusion detection. This pre-processing step establishes a baseline for comparison, enabling more accurate current intrusion assessment without repeating all detection operations from scratch.
3Device complexity
If only intrusion detection is provided without direction information, then device complexity is reduced, but loss of information increases
Solution Approach 1:
The patent merges intrusion detection with direction determination into a unified system. By combining these two functions that share common detection data and processing logic, the system provides comprehensive security information without proportionally increasing complexity. The same detection box data used for intrusion identification is also utilized for direction calculation.
Solution Approach 2:
The intrusion detection system is designed with multi-functionality, simultaneously providing intrusion detection, intrusion confirmation, and direction determination. This universal approach allows a single system to fulfill multiple security monitoring needs, reducing the requirement for separate specialized systems.

AI summary
An intrusion detection method includes steps of obtaining a current detection box and a historical detection box of a target in an input image; determining whether the current detection box has an intersection with a security line or a security area; determining that the target has an intrusion behavior if the current detection box has the intersection with the security line or the security area; and determining a direction of intrusion of the target according to the current detection box and the historical detection box.
