Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current belongings inspection systems face challenges in reducing waiting times, as they often require extensive secondary screenings for all detected items, leading to congestion and inefficiencies.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If secondary screening is performed on all detected persons, then detection reliability is improved, but waiting time increases and productivity decreases
Solution Approach 1:
The inspection process is segmented into primary screening and secondary screening stages. The primary screening uses electromagnetic wave transmission/reception to detect all persons, while secondary screening is performed only on selected individuals based on detection results and site conditions. This segmentation allows reliable detection while reducing waiting time by avoiding unnecessary secondary screenings.
Solution Approach 2:
The system dynamically adjusts the inspection process based on real-time conditions. The decision means evaluates detection results and current site conditions to dynamically determine which persons require secondary screening, optimizing the balance between detection reliability and waiting time reduction.
2Reliability
If secondary screening is performed on all detected persons, then detection reliability is improved, but productivity decreases
Solution Approach 1:
The inspection population is segmented into two groups: those requiring secondary screening and those who can proceed directly. This segmentation maintains detection reliability for high-risk individuals while improving overall productivity by allowing low-risk individuals to bypass the secondary screening process.
Solution Approach 2:
The system changes the inspection parameter (level of scrutiny) based on the detection results and site conditions. High-risk detections trigger secondary screening, while low-risk detections allow direct passage, optimizing productivity while maintaining reliability.
3Reliability
If all persons are inspected with the same process, then detection reliability is improved, but device complexity and operational complexity increase
Solution Approach 1:
The inspection system is segmented into different processing paths based on detection results. The electromagnetic wave transmission/reception means performs primary detection for all persons, while the decision means segments individuals into different groups, applying appropriate screening levels to each group, thereby managing complexity while maintaining reliability.
4Reliability
If secondary screening is performed on all detected persons, then detection reliability is improved, but congestion increases
Solution Approach 1:
The system segments the flow of persons into different paths: those requiring secondary screening and those who can proceed directly. This segmentation reduces congestion by preventing unnecessary accumulation of persons at secondary screening locations while maintaining detection reliability for those who require it.
