Lubricated Projectile Trap Fluid Deceleration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional projectile trap systems suffer from bullet ricochets, shattering, and fragmentation, leading to environmental pollution and high maintenance costs due to the escape of lead fragments and deterioration of interior surfaces.
Innovation Solution
A fluid lubricated projectile trap with a pressurized fluid containment system that directs a sheet of fluid across the bullet entry to decelerate projectiles and collect debris, with plumbing concealed below the trap units to reduce visibility and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional impact plates are used in projectile traps, then the trap can capture bullets, but bullets ricochet at high angles and shatter, causing lead pollution and environmental hazard
Solution Approach 1:
A fluid lubricant is introduced as an intermediary substance between the bullet and the impact plate. The lubricant forms a thin film on the impact plate surface, allowing the bullet to glide through the lubricant before impacting the plate, thereby reducing the harmful ricochet and shattering effects while maintaining effective bullet containment
Solution Approach 2:
The physical state of the impact plate surface is changed by applying a fluid lubricant layer. This parameter change transforms the dry, high-friction surface into a lubricated, lower-friction surface, which modifies the bullet's interaction with the plate and reduces harmful ricochet angles and fragmentation
2Object-generated harmful factors
If fluid systems are added to reduce airborne lead dust, then environmental impact is reduced, but plumbing complexity and visibility increase
Solution Approach 1:
The plumbing system is nested within the structural components of the trap. The fluid delivery system is integrated into the trap chamber walls and funnel structure, with plumbing concealed within the cylindrical chamber and funnel assemblies, eliminating the need for external exposed piping while maintaining fluid lubrication functionality
Solution Approach 2:
The fluid system serves multiple functions: it lubricates the impact plate to reduce ricochet, captures lead dust in the fluid stream, and the same fluid is recycled back to the reservoir. This multi-functionality reduces the need for separate systems and simplifies the overall plumbing architecture
3Reliability
If fluid is sprayed into the cylindrical chamber from the top, then bullet entry is lubricated, but exposed plumbing is required on top of the trap units
Solution Approach 1:
The fluid delivery system is repositioned from a top-down approach to a side-wall approach. Spray outlets are positioned on the side walls of the cylindrical chamber at the bullet entry level, allowing fluid to be delivered laterally into the chamber path, thereby eliminating the need for exposed top plumbing while maintaining effective lubrication
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 system effectively reduces airborne lead dust, minimizes environmental impact, and enhances safety by containing bullet fragments and debris, while reducing the complexity and visibility of plumbing, resulting in a more aesthetically pleasing and cost-effective solution.
Implementation Method 1
A pump is connected to the pressurized fluid containment and the reservoir. The spray from the spray outlets provides a sheet of fluid across the bullet entry to the deceleration trap chamber.
Implementation Method 2
at least one deceleration trap chamber unit with a forward funnel and with a lubrication system
Implementation Method 3
A slot in the bottom of the chamber allows bullets and fragments to fall by gravity into a reservoir below the chamber.

AI summary
A fluid lubricated projectile trap includes a substantially cylindrical chamber defined by a forward concave wall and a rearward concave wall. A bullet funnel extending forwardly therefrom. The funnel having a lower panel connecting to the forward concave wall in conjunction with an end plate defines a pressurized fluid containment with discharge outlets directed to the rearward concave wall. All plumbing may be secured below the ramp and forward of the chamber.
