Tool-Less Pistol Bushing Compensator With Quarter-Turn Bayonet Mount
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handgun compensators require separate tools for disassembly, making it difficult and potentially hazardous to disassemble 1911-style pistols without proper control of recoil spring components.
Innovation Solution
A bushing/compensator device with a quarter turn bayonet mount and a button assembly that allows for tool-less disassembly of the slide from the frame, enabling removal of the compensator without additional tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional compensator design is used, then the compensator can be attached to the barrel, but a separate tool is required for removal and disassembly
Solution Approach 1:
The patent combines the compensator and barrel bushing into a single integrated unit (bushing/compensator device). The compensator member includes features such as a square drive recess and external threading that allow it to function both as a compensator and as the barrel bushing, eliminating the need for separate tools for removal
Solution Approach 2:
The compensator member is designed to perform multiple functions: it serves as both the compensator device and the barrel bushing. The integrated design includes features like the square drive recess for tool-less removal, external threading for barrel attachment, and internal features for recoil spring plug engagement, allowing a single component to replace multiple traditional parts
2Ease of operation
If the compensator is removed by hand rotation, then no tool is needed, but control of recoil spring components is difficult and injury risk increases
Solution Approach 1:
The design incorporates a button assembly that can be depressed to preliminarily release the recoil spring plug from its engaged position. This preliminary action allows the barrel bushing and compensator to be safely rotated and removed without the risk of uncontrolled recoil spring component ejection
Solution Approach 2:
The button assembly acts as an intermediary mechanism between the user and the recoil spring plug. By providing a controlled method to release the plug through the button, the system mediates the potentially hazardous interaction between the user's hand rotation and the high-tension recoil spring components
3Length of moving object
If a full-length compensator is used, then the compensator maintains full length, but access to the recoil spring plug is blocked
Solution Approach 1:
The button assembly is nested within the compensator structure, with the button and its associated rod positioned inside the compensator member. This nested arrangement allows the full-length compensator to maintain its external dimensions while providing internal access to the recoil spring plug through the button mechanism
Solution Approach 2:
The design provides access to the recoil spring plug through a different dimensional approach - rather than creating an external aperture in the full-length compensator, the button assembly provides internal access through the compensator's structure, allowing plug engagement while maintaining the compensator's full external length

AI summary
A bushing/compensator device for a firearm is provided that includes a compensator member having a first aperture having an axis that is coaxial with the axis of the barrel. A second aperture has an axis that is coaxial with the axis of the guide rod when the device is mounted on the slide. A quarter turn bayonet mount is disposed at a rear end of the first aperture that mates with a bayonet mount aperture in the slide. When the bayonet mount is locked, the axis of the second aperture is aligned with the axis of the guide rod of the pistol, and when the bayonet mount is unlocked, the device is removable from the slide. A button assembly is retained in the second aperture and includes a head at one end and a fastener at the other. The rod is slidable from a first position wherein the head is adjacent to the front end of the second aperture, to a second position wherein the second end of the rod depresses the recoil spring plug. A spring biases the rod to the first position.
