Positioning device and method for positioning persons to be scanned
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional body scanner systems require operator involvement for positioning individuals, leading to increased scanning time and false alarms due to incorrect positions or postures.
Innovation Solution
A positioning device equipped with a camera, posture determiner, comparer, and display that automatically records and compares a person's posture to ideal templates, allowing for quick and accurate positioning without operator intervention, using a database for diverse body shapes and scaling for precise alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an operator manually positions the person to be scanned, then positioning accuracy is improved, but scanning time increases and operator involvement is required
Solution Approach 1:
The system enables self-positioning by providing real-time visual feedback through a display device that shows the difference between the current posture and the ideal posture. The person to be scanned can independently adjust their position based on this feedback without operator intervention, thereby reducing scanning time while maintaining positioning accuracy.
Solution Approach 2:
The system implements a feedback mechanism where the camera captures the person's posture, the posture determiner analyzes it, and the display device provides visual feedback showing the posture difference. This closed-loop feedback enables the person to self-correct their positioning, eliminating the need for manual operator guidance while maintaining high positioning accuracy.
2Measurement precision
If an operator manually positions the person to be scanned, then positioning accuracy is improved, but device complexity increases due to operator involvement
Solution Approach 1:
The system replaces the operator with an automated self-service mechanism. The camera, posture determiner, and display device work together to provide autonomous positioning assistance, eliminating the need for human operators while maintaining positioning accuracy through automated visual feedback.
Solution Approach 2:
The manual mechanical positioning process performed by the operator is replaced by an automated optical and computational system. The camera captures images, the posture determiner processes them algorithmically, and the display device presents the information, substituting the mechanical human operator with an automated technical system.
3Measurement precision
If manual positioning is used, then positioning control is improved, but the number of false alarms increases due to incorrect scanning positions
Solution Approach 1:
The real-time visual feedback system allows the person to continuously monitor and adjust their posture, ensuring they maintain the ideal scanning position. This continuous feedback and correction mechanism prevents positioning errors that would otherwise lead to false alarms, while eliminating the need for manual operator control.
Solution Approach 2:
The person takes active responsibility for their own positioning through the self-service system, continuously adjusting based on visual feedback. This self-monitoring and self-correction process ensures proper positioning throughout the scanning process, reducing positioning-related false alarms more effectively than intermittent manual checks.
