Solution Overview

Problem

Conventional imaging systems for detecting concealed security threats are either ineffective due to their inability to penetrate deeply into body cavities or are bulky and difficult to transport, as they require extensive disassembly and mechanical lifting equipment.

Innovation Solution

A compact imaging system with a translational mechanism that vertically translates an X-ray source and detector using a connecting member and linear actuators, allowing for independent movement and alignment, enabling efficient detection of concealed threats while maintaining a small form factor suitable for easy transportation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional imaging systems use extensive mechanical lifting equipment and large structures to achieve proper X-ray translation, then imaging capability is improved, but device size and portability deteriorate

Engineering Contradiction:
Improveimaging capabilityVSAvoiddevice size
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The patent combines the X-ray source and detector into a single integrated assembly that moves together as one unit, eliminating the need for separate lifting equipment for each component. This merging reduces the overall device size while maintaining imaging capability through coordinated translation of the combined assembly.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The translating assembly serves multiple functions simultaneously - it positions both the X-ray source and detector, provides geometric alignment, and enables vertical translation for imaging. This multi-functionality eliminates the need for separate mechanical lifting equipment, reducing device volume while maintaining reliability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Measurement precision

If conventional imaging systems use separate translation mechanisms for X-ray source and detector, then imaging precision is improved, but device complexity and ease of operation deteriorate

Engineering Contradiction:

AI summary

Imaging systems and methods are provided for detecting objects that may be hidden under clothing, ingested, inserted, or otherwise concealed on or in a person's body. An imaging assembly, e.g., X-ray source and X-ray detector, and mechanisms, e.g., a translational mechanism for vertically moving the imaging assembly, may be configured to reduce the overall form factor of such imaging systems, while still retaining an ability to perform full/complete imaging of a subject.
