Bushing Wrench Reciprocating Ejection Plunger Pistol Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bushing wrenches for 1911-style pistols lack control over the recoil spring and spring plunger during removal and installation, leading to unsafe and uncontrolled disassembly processes.
Innovation Solution
A bushing wrench with a reciprocating ejection plunger assembly that provides controlled retention and release of the spring plunger, allowing for simultaneous removal and installation of the barrel bushing, recoil spring, and spring plunger through compression and rotation, enhancing safety and operational ease.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional bushing wrenches are used for removal and installation of barrel bushing, then the basic function of removing and installing components is achieved, but the operator loses control over the recoil spring and spring plunger during disassembly and assembly processes
Solution Approach 1:
The patent introduces a receiving recess as an intermediary structure that temporarily holds the spring plunger during disassembly and assembly operations. This recess acts as a mediator between the barrel bushing and the spring plunger, allowing the operator to control the spring plunger's position and movement safely without direct manual manipulation during the critical phases of removal and installation.
2Ease of operation
If manual manipulation of off-hand and fingers is used to control spring plunger position, then the operator can place spring plunger in desired position, but the process becomes complex and time-consuming
Solution Approach 1:
The receiving recess provides a self-contained solution for spring plunger control. Once the recess is in place, it automatically guides and contains the spring plunger during compression and installation operations, eliminating the need for continuous manual manipulation of the operator's fingers and off-hand. The structure serves itself by providing inherent guidance and containment.
3Device complexity
If no retention mechanism is provided for spring plunger, then the device structure remains simple, but the operator experiences unwanted lack of control during locking and unlocking operations
Solution Approach 1:
The receiving recess is segmented into specific functional zones: a retention area for holding the spring plunger during compression, and a release area that allows controlled ejection. This segmentation allows the simple wrench structure to provide sophisticated control over the spring plunger through carefully designed geometric zones rather than complex mechanical mechanisms.

Function Achieved in This Case
The bushing wrench ensures secure containment and controlled release of the spring plunger, facilitating safer and more efficient disassembly and assembly of the pistol components, reducing the risk of accidents and improving user safety.
Implementation Method 1
providing radial and axial containment when linear compression is given to spring plunger (7)
Implementation Method 2
releasing spring plunger (7) by way of reciprocating ejection plunger assembly (3, 4, 5) being selectively activated
