Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IED deterrent systems are ineffective against IEDs attached to vehicles via adhesives or magnets, failing to protect vehicle occupants and prevent vehicle destruction, and are often impractical and expensive.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If custom fabricated body components or non-magnetic panels are used to prevent IED attachment, then IED attachment is hindered, but the system becomes impractical and expensive
Solution Approach 1:
The system performs preliminary detection of IED attachment attempts using sensors before the threat becomes critical. Magnetic sensors detect the presence of magnetic IEDs, vibration sensors detect attachment vibrations, and heat sensors detect thermal anomalies, enabling early warning and prevention without requiring expensive custom body components
Solution Approach 2:
The patent replaces mechanical/physical modification systems (custom fabricated body components, non-magnetic panels) with an electronic sensing and warning system. This substitution uses magnetic sensors, vibration sensors, and heat sensors to detect IEDs, eliminating the need for expensive and impractical physical modifications to vehicle bodies
2Object-affected harmful factors
If counter explosion systems are used to mitigate IED effects, then some protection is provided, but vehicle occupants are not fully protected and the vehicle is not prevented from being destroyed
Solution Approach 1:
The system applies preliminary anti-action by detecting IEDs and alerting occupants to flee or take protective actions before the explosion occurs. The warning system provides advance notice through visual, auditory, or tactile alerts, enabling occupants to escape to safe locations before the IED detonates, thereby preventing harm rather than merely mitigating effects
Solution Approach 2:
The system extracts the detection and warning functions from the vehicle's structural components and implements them as separate, dedicated sensor systems. Magnetic sensors, vibration sensors, and heat sensors are installed independently to detect IEDs, allowing the warning system to operate without relying on the vehicle's body structure
3Reliability
If existing IED deterrent systems are installed on vehicles, then some attachment prevention is achieved, but they are ineffective against IEDs attached via adhesives or magnets and provide no protection against successfully attached IEDs
Solution Approach 1:
The system achieves universality by implementing multiple sensor types that can detect various IED attachment methods. Magnetic sensors detect magnetic IEDs, vibration sensors detect attachment vibrations from any method, and heat sensors detect thermal anomalies from explosive materials regardless of attachment method, making the system effective against adhesives, magnets, and other attachment techniques
Solution Approach 2:
The system segments the detection function into multiple independent sensor types, each specialized for detecting different aspects of IEDs. Magnetic sensors detect magnetic fields, vibration sensors detect mechanical vibrations, and heat sensors detect thermal signatures, allowing the system to detect IEDs attached by different methods through multiple independent detection channels

AI summary
An explosive device detection and expulsion system broadly comprising a detection subsystem for sensing an IED attached to a vehicle and an expulsion subsystem for expelling the IED from the vehicle. The detection subsystem includes a sensor for detecting an IED via an electromagnetic field change or capacitance change, vibrations, and/or heat, and a controller for activating the expulsion subsystem upon receiving a detection signal from the sensor. The expulsion subsystem includes a deployable panel configured to be attached to the vehicle and a deployable mechanism for shifting the deployable panel from an undeployed state to a deployed state so as to expel the IED from the vehicle.
