Firearm Barrel Preloading Device for Quick Interchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional firearms require significant torque and specialized tools to install and remove barrels, which can damage components and affect accuracy, and often necessitate drilling holes into the receiver.
Innovation Solution
A preloading device using a split collar and barrel nut system that applies controlled force to the threaded connection, allowing for easy barrel replacement with common tools and maintaining alignment without damaging the barrel or receiver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional threaded connections are used to install barrels, then barrel replacement is possible, but significant torque and specialized tools are required which can damage components
Solution Approach 1:
A barrel preloader device is introduced as an intermediary tool between the installer and the barrel threads. This device engages with the barrel threads and applies controlled preloading force to secure the barrel to the receiver without requiring excessive torque that could damage components. The preloader acts as a mediator that translates minimal installer input into the precise high force needed for secure barrel installation.
2Reliability
If conventional barrel installation methods are used, then barrels can be secured to the receiver, but specialized tools and drilling operations are required
Solution Approach 1:
The invention extracts and eliminates the need for specialized barrel nut wrenches, clamps, and drilling operations from the barrel installation process. By using a preloader device that engages directly with the barrel threads, the system removes the requirement for these complex specialized tools and modifies (drilling holes into the receiver) while maintaining reliable barrel connection security.
3Stability of the object's composition
If high torque is applied to secure the barrel, then connection stability is improved, but accuracy is adversely affected
Solution Approach 1:
The preloader device changes the parameter of force application from uncontrolled high torque to controlled precise preloading force. By using a device with defined mechanical advantages and controlled engagement, the system achieves the necessary connection stability through precise force application rather than brute force torque, thereby preserving firearm accuracy while securing the barrel to the receiver.

AI summary
A firearm barrel preloading device can preload threaded connections. The preloading device can include an outwardly facing barrel-contact surface, an outwardly facing receiver-contact surface, non-planar surfaces between the barrel-contact surface and the receiver-contact surface. The non-planar surfaces can include mated pairs of axisymmetric surfaces that cooperate to spread apart the barrel-contact surface and the receiver-contact surface when the preloading device is moved toward an expanded configuration.
