Disposable X-ray Tray Inlay with MOF Coating for Hygiene and Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for preventing the spread of pathogenic agents and detecting illicit substances like explosives and drugs at airports and public facilities are inefficient, leading to potential health risks and security breaches, as they either slow down the screening process or lack effectiveness in detecting hazardous materials.
Innovation Solution
A method utilizing a detachable single-use inlay with a paper or polymer layer, optionally coated with metal organic frameworks, attached to an X-ray tray to prevent pathogenic agent transfer and detect explosives and drugs, allowing for high-throughput security inspections without direct contact between items and the tray, and featuring a design that enables easy recycling or disposal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a detachable single-use inlay is attached to the X-ray tray, then pathogenic agent transfer is prevented, but device complexity increases
Solution Approach 1:
The X-ray tray system is segmented into a permanent tray component and a detachable single-use inlay component. The inlay can be easily attached and removed, allowing the tray to be reused while the inlay is disposed of after one use. This segmentation isolates the contamination risk to the disposable inlay while preserving the reusable tray.
Solution Approach 2:
The single-use inlay acts as an intermediary barrier between the baggage/personal items and the X-ray tray. It provides a protective interface that prevents direct contact and potential transfer of pathogenic agents, while still allowing the X-ray scanning function to work effectively through the inlay material.
2Measurement precision
If metal organic frameworks are applied to detect explosives and drugs, then detection capability is improved, but manufacturing complexity increases
Solution Approach 1:
Metal organic frameworks (MOFs) are porous materials with high surface area and tunable pore structures that can selectively adsorb and detect explosive and drug molecules. The porous nature of MOFs enables them to capture trace amounts of these substances, providing enhanced detection capability when integrated into the inlay.
Solution Approach 2:
The inlay is constructed as a composite material system combining the base paper or polymer layer with a coating layer containing metal organic frameworks. This composite structure integrates the mechanical properties of the substrate with the detection capabilities of the MOF coating, achieving both structural integrity and analytical functionality.
3Reliability
If single-use inlays are used for every passenger, then hygiene is improved, but productivity decreases
Solution Approach 1:
The single-use inlay is designed as a disposable, low-cost component that can be rapidly deployed and discarded. Its inexpensive nature allows for frequent replacement without significantly impacting operational costs or passenger throughput, maintaining hygiene standards while preserving productivity.
Solution Approach 2:
The single-use inlay is pre-prepared and packaged before use, allowing passengers to quickly place their items on it without requiring time-consuming preparation steps during the screening process. This preliminary preparation maintains hygiene while minimizing impact on passenger throughput.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents the transfer of pathogenic agents and enables rapid detection of illicit substances, enhancing security and reducing the risk of health outbreaks while maintaining high passenger throughput by using a disposable, recyclable inlay that does not interfere with X-ray scanning.
