Replaceable Bullet Trap for Ballistic Launch Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ballistically launched devices face limitations due to projectile spalling and embedment, which cause damage and prevent predictable projectile delivery, necessitating control over mass transfer to prevent damage to the device and allow for safe replacement of the bullet trap.
Innovation Solution
A retrievable ballistically launched delivery apparatus with a replaceable bullet trap is designed, featuring a launch delivery tube and a bullet trap with an axial cavity, where the projectile's impulse and momentum are transferred to the bullet trap for predictable deformation and containment, allowing for safe launch and retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a projectile is ballistically launched through a delivery device, then the device can deliver projectiles to target, but the projectile causes spalling and embedment that damages the device
Solution Approach 1:
The delivery device is segmented into a permanent launch delivery tube and a replaceable bullet trap component. The bullet trap is designed to be replaced after a predetermined number of uses or when deformation occurs, isolating the damage from the permanent structure and allowing continued operation of the launch system.
Solution Approach 2:
The bullet trap is designed as a disposable or limited-life component that absorbs the harmful effects of projectile embedment and spalling. After use, the bullet trap can be replaced rather than repaired, eliminating the need to repair or replace the entire delivery device.
2Force
If the projectile embeds into the device, then momentum transfer launches the device, but unpredictable embedment prevents safe delivery of subsequent projectiles
Solution Approach 1:
The bullet trap is pre-designed with a cavity and deformation characteristics that predictably accommodate projectile embedment. The trap's geometry and material properties are selected to ensure consistent deformation behavior that contains the projectile while transferring momentum to the delivery tube for launch.
Solution Approach 2:
The bullet trap is designed with specific geometric parameters (cavity shape, wall thickness, material properties) that control how the projectile embeds and deforms the trap. These parameters are optimized to achieve predictable mass transfer vector and containment while maintaining reliability for subsequent projectiles.
3Strength
If the bullet trap is made more robust to prevent damage, then device durability improves, but the complexity of replacing or maintaining the trap increases
Solution Approach 1:
The bullet trap is segmented as a separate, modular component that can be independently replaced. The trap includes features like engagement surfaces and alignment mechanisms that simplify installation and removal, reducing maintenance complexity despite the need for periodic replacement due to deformation.

Function Achieved in This Case
This solution enables predictable projectile embedding and containment, preventing device damage and allowing for easy replacement of the bullet trap, ensuring reliable and safe ballistic delivery without projectile escapement.
Implementation Method 1
An impulse and momentum of mass of the projectile may be transferred from the projectile to the replaceable bullet trap and then to the launch delivery tube to launch the launch delivery tube from the ballistic muzzle
