Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for detecting hazardous materials, such as nuclear materials and chemical agents, are either heavy and bulky, expose users to radiation, or have poor reliability and the risk of detonating materials, especially when trying to detect shielded or remote targets.
Innovation Solution
A system that transmits electromagnetic energy towards a target area, collects and analyzes the scattered energy's absorption spectrum to identify hazardous materials, using millimeter-wave and far-infrared spectroscopy to detect changes in atmospheric molecules indicative of nuclear or non-nuclear materials, allowing for safe and remote detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional passive detection techniques are used to detect nuclear material by direct measurement of gamma rays and neutrons, then detection capability is achieved, but the user is exposed to high dose radiation and the system is heavy and bulky
Solution Approach 1:
The patent uses electromagnetic energy (millimeter-wave and far-infrared radiation) as an intermediary to detect hazardous materials indirectly. Instead of directly measuring nuclear radiation, the system transmits electromagnetic energy through the atmosphere and analyzes the scattered energy's absorption spectrum, which contains signatures of hazardous materials. This intermediary approach eliminates direct radiation exposure to users while maintaining detection capability.
Solution Approach 2:
The patent replaces the mechanical/radiological detection system (direct gamma ray and neutron measurement) with an electromagnetic spectroscopy system. By using millimeter-wave and far-infrared electromagnetic radiation and analyzing absorption spectra, the system substitutes a non-invasive optical method for the traditional radiological detection approach, eliminating the need for heavy shielding and reducing system complexity.
2Length of stationary object
If conventional passive detection techniques are used for long distance remote detection, then detection range is extended, but the system becomes heavy and bulky and cost increases
Solution Approach 1:
The patent replaces heavy passive radiation detection systems with an active electromagnetic spectroscopy system that transmits and analyzes scattered electromagnetic energy. This substitution enables long-distance detection (beyond 100 meters) without requiring heavy shielding or complex passive detection infrastructure, as the system actively probes the atmosphere for spectral signatures of hazardous materials.
3Reliability
If conventional active interrogation techniques using neutron, gamma ray, or muon beams are used to detect hazardous materials, then detection capability is improved, but reliability decreases and there is potential to detonate hazardous material
Solution Approach 1:
The patent changes the energy parameters from high-energy particle beams (neutrons, gamma rays, muons) to lower-energy electromagnetic radiation in the millimeter-wave and far-infrared ranges. This parameter change maintains detection capability through spectral analysis while eliminating the harmful effects of high-energy interrogation, including the risk of inducing nuclear reactions or detonating explosive materials.
Solution Approach 2:
The patent converts the previously harmful high-energy radiation into a beneficial low-energy electromagnetic probe. By using millimeter-wave and far-infrared radiation, the system transforms what would have been a dangerous interrogation method into a safe detection approach that still provides reliable identification of hazardous materials through their unique absorption spectral signatures.
4Device complexity
If conventional passive detection methods are used, then simple detection is achieved, but detection distance is limited to less than 100 meters
Solution Approach 1:
The patent performs preliminary action by actively transmitting electromagnetic energy through the atmosphere before detection occurs. This active probing of the atmospheric path allows the system to detect hazardous materials at distances beyond 100 meters, as the transmitted energy interacts with atmospheric molecules and hazardous material signatures along the entire path, providing extended detection range while maintaining relatively simple spectral analysis.
