Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security screening methods, such as Terry Frisks and consensual searches, are invasive, costly, and prone to errors, posing risks to both security personnel and individuals, while temporary event security setups are cumbersome and inefficient.
Innovation Solution
A portable, high-resolution imaging system with decoupled analog and digital components, including a radar system on a chip and digital processing units, allows for non-invasive detection of concealed objects by dividing components into separate housings for ergonomic attachment to user equipment, enabling contactless scanning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional security screening methods (Terry Frisks, consensual searches) are used, then security personnel can detect concealed objects, but the methods are invasive, pose risks to security personnel, and are prone to errors
Solution Approach 1:
The patent replaces mechanical physical contact (hand frisks, body searches) with electromagnetic field-based radar imaging technology. The system uses millimeter-wave radar to create images of concealed objects without physical contact, eliminating the harmful factors associated with manual searches while maintaining detection capability.
Solution Approach 2:
The patent introduces radar electromagnetic waves as an intermediary between the security personnel and the subject. Instead of direct physical contact, the radar waves serve as a mediator to detect concealed objects, allowing security personnel to obtain information about hidden items without being in close physical proximity to potentially dangerous subjects.
2Reliability
If consensual searches are conducted at venues, then unwanted items can be prevented from entering, but the process is slow, error-prone, and requires expensive manpower and equipment
Solution Approach 1:
The patent replaces manual visual inspection and physical pat-downs with automated radar imaging technology. The system automatically captures, processes, and analyzes images of concealed objects, eliminating human error and significantly increasing screening throughput while maintaining high detection accuracy.
Solution Approach 2:
The radar system performs automatic detection, image generation, and object identification without requiring manual intervention for each screening. The system processes multiple subjects sequentially or in parallel, with the radar automatically adjusting parameters and generating results, thereby increasing productivity while reducing the need for expensive security manpower.
3Reliability
If security equipment is deployed for temporary events, then security can be provided, but the setup is cumbersome and requires equipment to be set up before and removed after events
Solution Approach 1:
The patent divides the radar security system into separate functional modules: analog imaging components in one housing and digital processing components in another housing. This segmentation allows the system to be configured in different arrangements and makes setup and teardown simpler for temporary events, as components can be independently deployed or stored.
Solution Approach 2:
The patent creates a flexible, reconfigurable security system where the analog and digital housings can be positioned and connected in different configurations depending on the specific event requirements. This dynamic adaptability allows rapid deployment for temporary events without cumbersome fixed installations.
4Volume of moving object
If analog and digital components are integrated in one housing, then the system is compact, but the system lacks flexibility for ergonomic attachment to user equipment
Solution Approach 1:
The patent physically separates the analog imaging components into one housing and the digital processing components into another housing. This segmentation allows each housing to be independently sized and shaped for optimal attachment to different user equipment, providing flexibility while maintaining system functionality.
Solution Approach 2:
The patent designs the separate housings to be universally attachable to various types of user equipment. The analog housing can be mounted on vehicles, handheld devices, or fixed structures, while the digital housing can be positioned remotely or attached to different platforms, making the system adaptable to multiple applications and user needs.

AI summary
A system for scanning targets for concealed objects comprises a set of analog imaging components of a portable radar system with both a ranging resolution and lateral resolution sufficient to detect an object concealed on a person, where the analog imaging components are contained with a first housing and in communication with digital processing components contained in a second housing, where the digital processing components are configured to receive imaging information from the analog components for processing. Each housing is configured to be attached to a user's article of equipment.
