Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm systems lack an effective mechanism to safely stop a live bullet if mistakenly fired instead of a blank bullet, posing a risk to users and equipment.
Innovation Solution
A firearm attachable bullet trap with a hollow body and a bullet deforming part featuring stationary cutter blades that slow down and stop live bullets by detaching material and reducing kinetic energy, integrated with a ballistic plate to ensure complete stoppage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a firearm is configured to fire blank cartridges, then it can be used for theatrical or training purposes, but it lacks the capability to safely stop a live bullet if mistakenly fired
Solution Approach 1:
The bullet trap device is nested into the muzzle end of the firearm barrel, with the hollow body containing the ballistic plate and bullet deforming part inside the barrel structure. This integration allows the safety mechanism to be incorporated without adding external complexity to the firearm system.
Solution Approach 2:
The bullet deforming part with stationary cutter blades acts as an intermediary between the live bullet and the ballistic plate. It first deforms and slows the bullet through material detachment, then the ballistic plate provides final stoppage, creating a two-stage protection system.
2Reliability
If a bullet trap is designed to stop live bullets effectively, then it can prevent damage and injury, but it may interfere with the firing of blank cartridges
Solution Approach 1:
The stationary cutter blades are positioned to engage only with live bullets that have sufficient velocity and mass to activate them. Blank cartridges, having less mass and velocity, pass through the bullet deforming part without triggering the cutting mechanism, allowing the blades to selectively affect only live bullets.
Solution Approach 2:
The connection means between the bullet deforming part and hollow body is designed to break or deform under the force of a live bullet, allowing the bullet deforming part to move relative to the hollow body in response to receiving kinetic energy from a live bullet. This dynamic response enables the system to differentiate between live bullets and blank cartridges.
3Use of energy by moving object
If stationary cutter blades are added to deform bullets, then kinetic energy is reduced more effectively, but the device complexity increases
Solution Approach 1:
The bullet deforming part is segmented into multiple stationary cutter blades arranged around the central channel, each blade independently contributing to bullet deformation. This segmentation allows the system to progressively remove material and reduce kinetic energy through multiple small interactions rather than requiring a single complex mechanism.
Solution Approach 2:
The bullet deforming part combines stationary cutter blades made of hard material with a connection means designed to break or deform, creating a composite structure that serves dual functions: cutting bullet material and providing dynamic response to different cartridge types.
