Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security screening systems face inefficiencies in analyzing liquid, aerosol, or gel (LAG) materials due to the large volume of data from surrounding materials, leading to prolonged analysis times and increased error rates in identifying the properties of LAG materials.
Innovation Solution
A tray insert with longitudinal recesses is used to stabilize containers holding LAG materials and restrict data processing to specific angular ranges, utilizing electromagnetic radiation sources, detectors, and optional cameras to enhance data accuracy and speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the scanning system analyzes all data from surrounding materials and LAG materials, then the assessment is comprehensive, but the analysis time increases and throughput decreases
Solution Approach 1:
The patent segments the scanning area into multiple zones using physical barriers (walls) within the tray insert. These walls create distinct compartments that separate LAG materials from surrounding materials, allowing the system to process different zones independently and reduce the computational burden of analyzing all data simultaneously.
Solution Approach 2:
The patent extracts and isolates the data relevant to LAG materials by using physical barriers to confine them in specific zones. This allows the system to exclude data from surrounding materials in non-recess areas, thereby reducing the overall data volume that requires intensive processing while maintaining comprehensive assessment of the LAG materials themselves.
2Measurement precision
If the scanning system processes large volume of data from surrounding materials, then the assessment is thorough, but the analysis speed decreases
Solution Approach 1:
The tray insert divides the scanning field into segmented zones using vertical and horizontal walls. This segmentation allows the system to focus processing power on specific zones containing LAG materials, improving analysis speed while maintaining assessment accuracy through targeted zone-by-zone evaluation.
Solution Approach 2:
The patent applies local quality by creating distinct scanning zones with different processing requirements. Zones containing LAG materials receive detailed analysis, while zones with only surrounding materials receive reduced or excluded processing, thereby optimizing the balance between assessment accuracy and analysis speed.
3Measurement precision
If the iterative process analyzes greater amount of data, then the best fit solution is more accurate, but the time to determine LAG material properties increases
Solution Approach 1:
The patent extracts and removes data from surrounding materials by using physical barriers to confine LAG materials in specific recess zones. This extraction reduces the total data volume subjected to iterative processing, thereby decreasing analysis time while maintaining the accuracy of the best fit solution for the LAG materials through focused processing of relevant zones.
Solution Approach 2:
The tray insert performs preliminary spatial organization of materials before scanning by confining LAG materials to specific zones. This preliminary action reduces the search space for iterative algorithms, allowing them to converge faster on accurate solutions without compromising the thoroughness of the analysis.
4Reliability
If the scanning system includes more data representing surrounding materials, then the overall assessment is complete, but the potential for error in identifying LAG material increases
Solution Approach 1:
The patent segments the scanning field into distinct zones using walls that separate LAG materials from surrounding materials. This segmentation reduces the potential for error by preventing data from surrounding materials in non-recess areas from being incorrectly associated with LAG materials, while maintaining assessment completeness through systematic zone-by-zone evaluation.
Solution Approach 2:
The tray insert implements local quality by creating zones with different data processing characteristics. Zones containing LAG materials receive focused, accurate processing, while zones with surrounding materials are either processed separately or excluded, thereby improving identification accuracy without sacrificing the completeness of the overall assessment.

AI summary
An article for screening includes a top surface and a bottom surface. A forward wall, an aft wall and side walls each extend between the top surface and the bottom surface. A longitudinal recess extends at least partially across the top surface has a first lateral wall extending away from the top surface toward the bottom surface and meeting with a base wall at a predetermined angle therebetween for positioning of a liquid material relative to the first lateral wall and the base wall. The predetermined angle is for restricting data in a data range provided by a scanning operation of the liquid material to data provided within the predetermined angle between the first lateral wall and the base wall of the recess. The liquid material may be contained within a container positioned within the recess. Preferably, the article is an insert for a security screening tray.
