Solution Overview
Problem
Existing security scanners have suboptimal detection rates and high false alarm rates due to reliance on static poses, which limits the effectiveness of threat detection and increases examination duration.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple scans at different body poses are captured and correlated, then the illumination of body parts is improved and threat detection rate increases, but the device complexity and examination duration increase
Solution Approach 1:
The scan data is segmented into different body pose categories (static poses and dynamic movements) and processed separately. The processor correlates sections of scans showing body parts at different poses, dividing the complex task of multi-pose analysis into manageable segments that can be processed systematically to improve illumination without overwhelming system complexity.
Solution Approach 2:
The system dynamically adapts its operation mode based on detected body poses. When dynamic movements are detected, the system adjusts beam configurations and scanning parameters in real-time. This dynamic adaptation allows the system to optimize illumination of moving body parts while managing computational resources efficiently.
2Measurement precision
If multiple scans at different body poses are captured and correlated, then threat detection rate increases, but examination duration increases
Solution Approach 1:
The pose detection sensor continuously monitors for body pose changes before initiating scans. When a person enters the scanning area, the system preliminarily detects their pose and prepares the appropriate beam configuration in advance. This preliminary action ensures that when scanning begins, the system is already optimized for the detected pose, reducing overall examination time while maintaining high detection rates.
Solution Approach 2:
The system maintains continuous scanning operation without interruption. By capturing scans at both static poses and dynamic movements continuously, the system ensures that no potential threat is missed while minimizing idle time. The correlation processor works continuously to integrate scan data, ensuring that examination time is minimized while maintaining comprehensive coverage.
3Loss of time
If scans are captured during dynamic movement, then examination duration is reduced, but measurement precision may be compromised
Solution Approach 1:
The pose detection sensor provides continuous feedback on body pose changes during the scanning process. Based on this feedback, the processor dynamically adjusts beam configurations and scanning parameters to maintain measurement precision even when the person is moving. This feedback loop ensures that scan quality is preserved while capturing dynamic movements that reduce examination duration.
Solution Approach 2:
The system changes scanning parameters such as beam configuration, scanning speed, and resolution based on the detected body pose and movement state. When dynamic movements are detected, the system adjusts parameters to optimize both scan quality and examination speed, ensuring that measurement precision is maintained while reducing overall examination time.
4Illumination intensity
If beam configuration is adapted to body poses, then illumination quality is improved, but device complexity increases
Solution Approach 1:
The beam configuration system is designed to handle multiple body poses and movement states using a unified approach. The same beam configuration framework adapts to different scenarios (static poses, walking in, walking out) by adjusting parameters within the existing system architecture. This multi-functional design improves illumination quality without proportionally increasing device complexity.
