Portable Bullet Trap Rail System for Shoot House Repositioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable bullet traps are heavy, difficult to move, and occupy valuable space in shoot houses, limiting their repositioning and causing wear and tear on the training environment due to high shooting density.
Innovation Solution
A portable bullet trap system that includes a rail system for easy attachment and removal from the shoot house wall, allowing the trap to be slid along the wall, combined with adjustable positioning and deceleration mechanisms like louvers or baffles to manage bullet impact effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If portable bullet traps are made heavy with thick steel plate, then bullet containment reliability is improved, but ease of moving the trap deteriorates
Solution Approach 1:
The bullet trap is divided into two main segments: a heavy stationary base containing the steel plate box for bullet containment, and a separate movable target assembly that can be repositioned independently. This segmentation allows the heavy containment structure to remain fixed while the lighter target portion is easily moved to different locations.
Solution Approach 2:
A wheeled base or cart serves as an intermediary mechanism between the operator and the heavy bullet trap. The wheels reduce friction and enable easy movement of the entire trap assembly, while the heavy steel box remains enclosed and protected during transport.
2Reliability
If bullet traps are placed on stands with broad base for stability, then shooting stability is improved, but space utilization deteriorates
Solution Approach 1:
Instead of extending the base horizontally to provide stability, the bullet trap uses vertical dimension by mounting the target on an adjustable stand with telescoping legs. The stability is achieved through vertical adjustment and locking mechanisms rather than horizontal spread, preserving floor space in the shoot house.
Solution Approach 2:
The stand uses adjustable and lockable legs that can be extended or retracted as needed. During shooting, the legs are extended and locked to provide stability. When moving or storing, the legs are retracted to minimize space occupation. This dynamic adjustment resolves the contradiction between stability and space utilization.
3Area of stationary object
If targets are hung from walls to save space, then space utilization is improved, but ease of repositioning deteriorates
Solution Approach 1:
The target system is segmented into a wall-mounted rail component and a separate movable target assembly with wheels. The rail remains fixed to the wall to save space, while the target assembly can be easily moved along the rail or removed entirely for repositioning to different locations in the shoot house.
4Productivity
If portable bullet traps are used in high shooting density environments, then training capacity is improved, but wear and tear on the shoot house deteriorates
Solution Approach 1:
The bullet trap extracts the high-wear shooting activity from the permanent shoot house structure by providing a separate, portable containment unit. All bullet impacts occur on the portable trap's steel plate and target, not on the shoot house walls. The trap can be moved to different locations, distributing wear away from any single area of the shoot house and allowing continuous training without damaging the permanent structure.
Applied Scientific Principles

Function Achieved in This Case
Enables easy repositioning of the trap near the wall, reducing space wastage and minimizing wear on the training environment, while allowing the use of higher-powered rounds without damaging the trap, thus enhancing training efficiency and safety.

AI summary
A portable bullet trap includes a rail which is attachable to a shoot house or other ballistic wall and a trolley which facilitates movement of the bullet trap along the rail. Additionally a bullet trap may include a plurality of pivotable baffles or other structures disposed therein to deflect and partially decelerate a bullet.
