Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current auto-loading pistols using magnum cartridges face challenges with high recoil, leading to slide and frame damage, and are made heavier or more difficult to handle by increasing weight or recoil spring strength, limiting their popularity and reliability.
Innovation Solution
A firearm design featuring a rotating barrel with muzzle-mounted locking lugs and a replaceable energy buffer to absorb recoil energy, allowing for enhanced accuracy and strength without excess weight or strong recoil springs, and enabling lighter and more accurate pistols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If increased slide/barrel weight is used to mitigate recoil impact, then reliability improves, but portability and ease of operation deteriorate
Solution Approach 1:
The patent applies beforehand cushioning by introducing a buffer device that absorbs recoil energy before it can damage the slide and frame. The buffer is positioned to intercept the recoil force during the rearward movement of the slide, converting harmful kinetic energy into compressive force on the buffer material, thereby protecting the pistol structure without requiring excessive weight.
2Reliability
If recoil spring strength is increased to mitigate recoil impact, then reliability improves, but ease of operation deteriorates due to difficulty in charging and clearing the pistol
Solution Approach 1:
The buffer device provides beforehand cushioning by absorbing excess recoil energy that would otherwise require a stronger recoil spring to handle. This allows the use of a milder recoil spring that is easier to compress during manual charging operations, while still providing adequate recoil management during firing.
Solution Approach 2:
The buffer acts as an intermediary between the recoil force and the recoil spring, absorbing some of the impact energy and reducing the burden on the spring. This mediation allows the system to handle high-recoil magnum cartridges while maintaining reasonable ease of operation for charging and clearing.
3Power
If magnum power cartridges are used for hunting and self defense, then stopping power and effectiveness improve, but recoil energy and potential for damage increase
Solution Approach 1:
The buffer device converts the harmful recoil energy generated by magnum cartridges into a beneficial cushioning effect. By absorbing and dissipating the excess energy through controlled deformation, the buffer transforms what would be destructive force into a protective mechanism that allows safe use of high-power ammunition.

AI summary
A firearm such as a pistol includes a barrel which rotates and travels linearly relative to a frame of the pistol and a slide which travels linearly relative to the barrel and frame. The barrel has at least one stop located at a muzzle end for engaging at least one stop on the slide when the barrel is in a first rotational position to prevent linear movement of the slide relative to the barrel, which stops permit the slide and said barrel to move linearly relative to one another when the barrel is in a second rotational position. Another aspect of the invention comprises a control surface which is located on a barrel of a firearm. Yet another aspect of the invention comprises such features associated with a rotating, rather than tipping, firearm barrel. Yet another aspect of the invention comprises a replaceable energy buffer for a firearm.
