Blank Safety Device with Bullet Plug for Firearm Adapter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of blank ammunition in training poses risks due to the potential for live rounds to be fired, which can cause dangerous situations, and existing adapters do not adequately prevent live rounds from exiting while providing sufficient gas pressure for normal firearm operation.
Innovation Solution
A blank safety device with a cylindrical body and a back section that includes a bullet plug and a sealed internal chamber, which, when a live round is fired, allows the gun blast to escape through a port, alerting the user and preventing the bullet from exiting, while maintaining gas pressure for normal operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a blank firing adapter is used to prevent live rounds from exiting, then safety is improved, but the device complexity increases
Solution Approach 1:
The adapter is divided into distinct functional segments: a bullet plug component that seals the bore, a back section with sealed chamber, and an internal cavity system with ports. This segmentation allows each component to perform its specific safety function independently while maintaining overall system manageability.
Solution Approach 2:
The bullet plug is received within the bore of the adapter body, and the back section is received within the adapter body, creating a nested structure. The sealed chamber is nested within the back section, and the internal cavity system is integrated within the adapter body. This nesting reduces the number of separate external components.
2Reliability
If the adapter prevents live rounds from exiting, then safety is improved, but the gas pressure for firearm operation deteriorates
Solution Approach 1:
The adapter provides different properties at different locations: the bore region has a sealed bullet plug to prevent bullet exit, while the back section has a sealed chamber with controlled ports to regulate gas pressure. This local differentiation allows simultaneous achievement of safety and adequate gas pressure for firearm cycling.
Solution Approach 2:
The sealed chamber with its port system acts as an intermediary between the firearm's gas system and the external environment. It mediates the gas pressure by containing and regulating it, ensuring sufficient pressure is maintained for firearm operation while preventing uncontrolled release.
3Loss of information
If the sealed back section is pierced by a live round, then the user is alerted through gun blast escape, but the structural integrity deteriorates
Solution Approach 1:
The bullet plug is positioned in advance within the bore, ready to seal it before a live round is fired. This preliminary placement ensures that when a live round is accidentally chambered, the bullet plug is already in position to contain the bullet while allowing the gun blast to pierce the back section and alert the user.
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 solution effectively prevents live rounds from being fired while ensuring sufficient gas pressure for firearm operation, alerting the user to the mistake through a distinct sound and smoke, thereby enhancing safety during training.
Implementation Method 1
the bullet plug being configured to distally displace within the bore towards the closed distal end in response to the impact of a fired bullet
Implementation Method 2
the live round pierces the sealed back section such that a gun blast travels through the internal cavity and through the port to the external environment

AI summary
In one embodiment, a blank safety device is provided that includes: a body defining a cylindrical bore having a closed distal end, the body also defining an proximally extending internal cavity in communication with the cylindrical bore; a bullet plug received within the cylindrical bore, the bullet plug being configured to distally displace within the cylindrical bore towards the closed distal end in response to the impact of a fired bullet; and a back section received within the internal cavity in the body, the back section defining an internal chamber that is sealed with respect to a proximal bore for receiving a firearm attachment.
