Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IED detection training devices are bulky, require hazardous blasting caps and explosives, and are not easily portable, making them difficult to transport and use in field situations.
Innovation Solution
A portable, handheld IED detection training device that uses standard blank ammunition rounds as the detonating charge and can be triggered by either electronic sensor inputs or mechanical means, such as a trip wire, featuring a firing pin mechanism with a spring and lever system for safe and efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional blasting caps and explosive charges are used in IED training devices, then realistic detonation effect is achieved, but device size increases and portability decreases
Solution Approach 1:
The patent extracts the explosive charge (blasting cap and explosive material) from the training device and replaces it with a blank ammunition cartridge that can be fired through a barrel. This removes the bulky hazardous materials while maintaining the training function of simulating an IED detonation effect through the blank cartridge discharge.
Solution Approach 2:
The patent creates a simplified copy of the IED detonation mechanism by using a blank ammunition cartridge instead of actual explosives. The blank cartridge replicates the firing action and visual effect of a detonation without requiring the actual explosive charge, thereby reducing device volume while maintaining training realism.
2Reliability
If blasting caps and explosive charges are used, then detonation function is achieved, but transportation hazard and complexity increase
Solution Approach 1:
The patent removes the hazardous blasting caps and explosive charges from the system, replacing them with standard blank ammunition cartridges. This extraction eliminates the transportation hazard associated with storing and moving actual explosives while maintaining the essential detonation function through the blank cartridge firing mechanism.
Solution Approach 2:
The patent employs disposable blank ammunition cartridges instead of reusable explosive charges. These cartridges can be safely stored and transported, used once to simulate detonation, and then discarded, eliminating the need for handling and transporting hazardous explosive materials while maintaining the training function.
3Reliability
If complex firing mechanisms are used to trigger detonation, then activation reliability is improved, but device complexity and ease of operation worsen
Solution Approach 1:
The patent employs a universal firing mechanism that can accept multiple types of activation inputs (electronic sensor signals or mechanical trip wire activation) to trigger the blank cartridge discharge. This multi-functional approach maintains activation reliability across different training scenarios while simplifying the overall device design by using a common firing mechanism for both electronic and mechanical triggers.

Function Achieved in This Case
Enables a compact, safe, and cost-effective IED detection training device that can be easily transported and used in various field scenarios, allowing for realistic training simulations without the need for explosive charges and facilitating quick reset and repetitive training exercises.
Implementation Method 1
A spring can surround the firing pin... the spring can be compressed. To fire the device, the pull ring can be pivoted... which can further cause the lever to pivot and disengage the tab, which can further cause the spring to relax, which forces the firing pin forward

AI summary
An IED detection training device can include a barrel which can be adapted to receive a blank ammunition cartridge. A housing can be connected to the barrel, and a firing pin having a tab extending from the firing pin can be disposed in the housing. A spring can surround the firing pin, and a sleeve having a slot can surround the sleeve so that the firing pin tab is disposed in the sleeve slot. A lever can be pivotably attached to the housing so that the lever selectively engages the tab. A pull ring can also be pivotably attached to the housing, to selectively engage the lever. Pivoting of the pull ring can cause pivoting engagement of the lever and disengagement of the tab, which can further cause the spring to move the firing pin forward to strike the ammunition blank cartridge.
