Screening Cabin Projector for Autonomous Security Checks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional security screening methods, such as metal detection portals and radio wave scanners, often result in delays and increased resource utilization due to the need for manual operator intervention and potential interference from display panels, which can obstruct or emit radiofrequency signals, causing inefficiencies and increased stress on individuals being screened.
Innovation Solution
A screening device with a cabin equipped with sensors and a projector that provides instructions to individuals, allowing for autonomous screening without manual operator intervention, using sensors like millimeter wave or terahertz scanners, and a control device that processes data to identify potential security risks and project instructions for the individual to follow, reducing delays and interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual operator intervention is used in traditional screening methods, then security screening can be performed, but delays and increased resource utilization occur
Solution Approach 1:
The system enables self-service screening by providing the screened person with autonomous control over the screening process through projected instructions. The person can independently follow displayed guidance to complete screening procedures without requiring manual operator intervention, thereby eliminating delays while maintaining security effectiveness.
Solution Approach 2:
The patent replaces the mechanical system of manual operator intervention with an automated information projection system. Instead of operators providing verbal or written instructions, the system uses projectors to display visual instructions directly in the screening area, enabling automated guidance and reducing dependency on human operators.
2Loss of information
If display panels are used to provide instructions, then information can be displayed to the person, but radiofrequency signal interference occurs
Solution Approach 1:
The patent substitutes electronic display panels with a projection-based information delivery system. By using projectors to cast visual instructions onto surfaces within the screening area, the system eliminates the need for display panels that emit radiofrequency signals, thereby maintaining effective instruction delivery while avoiding electromagnetic interference with security sensors.
3Reliability
If the person is required to enter a closed cabin, then security screening can be performed, but stress on the individual increases
Solution Approach 1:
The system introduces visual instructions as an intermediary between the screening system and the individual. By projecting clear, step-by-step guidance into the screening area, the system helps individuals understand and navigate the screening process independently, reducing confusion and psychological stress while maintaining screening accuracy.

AI summary
A screening device for screening a person includes a cabin including a wall at least partly enclosing an inner space, and a sensor on at least part of the surface of the wall facing the inner space, the sensor being configured to sense the person present in the inner space. The screening device includes a projector projecting an image into the inner space to be viewed by the person, and a control device connected to the sensor and the projector and configured to operate the sensor to sense the person residing in the inner space, and drive the projector to project instructions to the person, associated with the operating of the sensor. The screening system may further include a hand luggage screening apparatus.
