Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional image verification methods are used at security checkpoints, then the system is simpler to operate, but the detection accuracy of prohibited objects is reduced
Solution Approach 1:
The system divides the detection task into multiple specialized machine learning models: a first model detects electronic devices and their locations, a second model detects hazardous materials, and a third model determines compliance. This segmentation allows each model to specialize in specific detection tasks, improving overall accuracy while maintaining manageable system complexity through modular architecture.
Solution Approach 2:
The system changes the parameter of detection methodology from traditional image verification to machine learning-based automated analysis. By transforming the detection approach and using trained models with specific parameters for identifying electronic devices, hazardous materials, and compliance rules, the system achieves higher detection accuracy.
2Productivity
If manual verification of images is used, then the system requires less computational resources, but the screening efficiency is reduced
Solution Approach 1:
The system implements self-service automated detection using machine learning models that independently analyze images without requiring manual verification. The models automatically detect electronic devices, locate them, identify hazardous materials, and determine compliance, enabling the system to perform screening functions autonomously and significantly improving productivity.
Solution Approach 2:
The system performs preliminary detection and classification using trained machine learning models before any manual review or alarm triggering. By pre-processing images through automated detection of electronic devices and hazardous materials, the system prepares the data in advance, reducing the need for manual intervention and improving overall screening efficiency.
3Reliability
If electronic devices are allowed in luggage without detection, then passenger convenience is improved, but security risks increase
Solution Approach 1:
The system implements feedback by automatically detecting electronic devices in luggage and providing information to determine compliance with security regulations. The machine learning models continuously analyze images, identify devices, locate them relative to luggage, and feed this information into the compliance determination process, creating a closed-loop system that maintains security while providing clear guidance.
Solution Approach 2:
The system uses machine learning models as intermediaries between the passenger's luggage and the security decision-making process. These models act as mediators that objectively detect and locate electronic devices, translating physical objects into detectable data patterns, and enable automated compliance determination without direct human intervention in the detection process.
