Disposable Bonding Material Injection for Small Arms Deactivation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need to efficiently disable small arms in field conditions, such as during war, port inspections, or shipboard operations, where limited manpower, skills, and equipment are available, and traditional methods like crushing or heating are not feasible.
Innovation Solution
A portable, single-use injection device that dispenses a bonding material, like epoxy, into the barrel and working parts of a weapon, rendering it inoperable by obstructing the firing mechanism and physically occupying the barrel, which can be left in place as a permanent indicator of inoperability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional methods like crushing or heating are used to disable small arms, then the weapon can be rendered inoperable, but these methods require extensive manpower, specialized equipment, and facilities that are unavailable in field conditions
Solution Approach 1:
The patent employs a disposable injection device that is simple, portable, and requires minimal training to operate. The device is designed for single-use field deployment, eliminating the need for complex reusable equipment or specialized facilities. After use, the device is discarded, providing a cost-effective solution that doesn't require maintenance or recovery operations.
Solution Approach 2:
The patent replaces heavy mechanical destruction methods (crushing, heating) with a chemical/bonding-based approach. The injection device delivers bonding material that chemically adheres to weapon components, rendering the weapon inoperable through material adhesion rather than physical destruction. This substitution eliminates the need for complex mechanical equipment while achieving reliable deactivation.
2Reliability
If weapons are guarded and transported to destruction locations, then proper disposal can be achieved, but this process is manpower intensive and occupies trained personnel who could be used elsewhere
Solution Approach 1:
The patent performs the deactivation action at the location where the weapon is seized, eliminating the need for subsequent transport and guarding operations. The injection device is used immediately in the field to render the weapon inoperable in place, so the weapon can be left secured without requiring trained personnel to guard or transport it to a destruction facility.
Solution Approach 2:
The bonding material itself serves multiple functions: it deactivates the weapon mechanism, plugs the barrel to prevent chambering, and creates a visible indicator of deactivation. This multi-functional material eliminates the need for additional guarding or transport operations, as the deactivated weapon can be left in place or easily secured by untrained personnel.
3Ease of operation
If a portable injection device is used to dispense bonding material into the weapon, then deactivation can be achieved with minimal manpower and training, but the device must be simple enough to operate in field conditions without extensive skills
Solution Approach 1:
The injection device is designed as a simple, segmented system with distinct functional components: a barrel for holding bonding material, a plunger for delivery, and a nozzle for injection. This segmentation allows each component to be optimized for its specific function while maintaining overall simplicity. The device can be operated by pushing the plunger, a动作 that requires minimal training but achieves reliable deactivation by delivering bonding material directly into the weapon's ejection port.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively disables small arms with minimal training and resources, ensuring the weapon cannot be chambered or fired, and serves as a durable indicator of its inoperable state, reducing the need for extensive manpower and equipment.
Implementation Method 1
the bonding material can interfere with the operation of the firing pin, extractor, bolt, magazine, and other moving components of the weapon, as well as physically occupying or plugging the breach or barrel of the weapon
Data Source
AI summary
A device and method for deactivating firearms is described herein. The device includes a casing having a nozzle and a plunger for dispensing a bonding material out of the nozzle. The device is inserted into the barrel of a weapon, and the material is injected into the barrel near the bolt face of the weapon. The bonding material enters the working mechanism of the firearm and hardens, interfering with operation of the firearm.
