Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surge suppressors are ineffective against the complex, multiple surges caused by nuclear weapon-induced electromagnetic pulses (EMPs), which consist of E1, E2, and E3 components, leading to potential false alarms and infrastructure damage.
Innovation Solution
A system and method that detects and isolates EMP-induced electrical system surges using a Detection, Isolation, and Monitoring of EMP (DIME) module, capable of identifying the E1 component in less than 10 nanoseconds and providing isolation in under 300 nanoseconds, along with shunts to suppress voltage differentials exceeding predetermined levels, effectively addressing E1, E2, and E3 components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional surge suppressors are used to protect against electromagnetic pulses, then they can handle common lightning strikes and electrical failures, but they are ineffective against the complex multiple surges (E1, E2, E3 components) caused by nuclear weapon-induced EMPs
Solution Approach 1:
The patent divides the surge protection function into three separate suppressor assemblies, each optimized for a specific EMP component (E1, E2, or E3). Each assembly contains suppressor elements with characteristics tailored to its target component's unique properties, allowing the system to effectively handle the complex multi-component EMP surge that conventional single-purpose suppressors cannot address
2Speed
If detection systems are made highly sensitive to detect EMP components, then detection speed improves, but false alarms increase due to inability to distinguish EMP from other electrical events
Solution Approach 1:
The patent employs detection systems that monitor electrical parameters and provide feedback to distinguish EMP events from other electrical phenomena. By analyzing specific characteristics of the detected surges and comparing them against known EMP signatures, the system can rapidly identify genuine EMP threats while filtering out false alarms from benign electrical events
Solution Approach 2:
The detection system utilizes changes in multiple electrical parameters (voltage, current, frequency, rise time) to identify EMP components. By monitoring how these parameters change in characteristic EMP patterns rather than relying on a single threshold, the system achieves both fast detection and high accuracy in distinguishing EMP from other electrical events
3Reliability
If isolation response time is reduced to protect against E1 component, then infrastructure protection improves, but system complexity increases due to need for ultra-fast response mechanisms
Solution Approach 1:
The patent incorporates pre-positioned isolation mechanisms and pre-programmed response protocols that are ready to activate immediately upon EMP detection. The isolation switches and protective devices are pre-configured in optimal positions, eliminating the need for complex real-time decision-making and mechanical adjustments during the nanosecond-scale E1 component event

AI summary
A system and method for suppressing EMP-induced electrical system voltage surges due to detonation of a nuclear weapon, the EMP comprising E1, E2, and E3 component pulses. A plurality of shunting assemblies, each including MOVs, gas discharge tubes, other mechanical, electrical and ionization discharge devices and combinations thereof, detect and react to the overvoltage according to timing parameters associated with each of the E1, E2, and E3 components and shunt the overvoltage to decrease to under a predetermined allowable level. Respective shunting assemblies may include automatic self-monitoring of any faults in respective circuitry and also a challenge mode for on-demand circuit monitoring using an optical coupling switch, the optocoupler including an infrared light supplied by an LED flashlight and having a phototransistor light receiver.
