Quick Disassembly Firearm Recoil Group via Manual Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearms require the use of auxiliary tools for disassembly and reassembly of recoil groups, leading to increased equipment needs, wear, and potential damage due to the need for hand tools.
Innovation Solution
A quick disassembly recoil group structure that allows for simple and fast assembly and disassembly by hand without the use of tools, featuring a recoil tube, recoil nut, locking piece, locking spring, centering bushing, and segment, enabling manual separation and reconnection of the recoil nut from the recoil tube.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional closed recoil group systems are used, then structural integrity is maintained, but disassembly requires additional tools which increases device complexity and user burden
Solution Approach 1:
The recoil group is divided into separable segments (recoil spring tube, recoil spring, follower, etc.) that can be independently accessed. The locking mechanism itself is segmented into a locking block and corresponding locking surfaces on the tube, allowing manual separation without tools.
Solution Approach 2:
The locking mechanism is designed to be self-operating through manual manipulation. The locking block can be manually moved between locked and unlocked positions by the user, and the spring-loaded design provides automatic engagement and disengagement assistance, eliminating the need for external tools.
2Ease of repair
If hand tools are used for disassembly, then complete dismantling is achieved, but wear and damage risks increase over time
Solution Approach 1:
The manual locking mechanism allows users to perform maintenance without tools, eliminating the wear and damage associated with tool usage. The direct manual operation on the locking block and locking surfaces prevents tool-induced deformation and damage to the recoil group components.
Solution Approach 2:
The locking block is extracted as a separate, manually operable component that can be moved independently to enable access to internal components like the recoil spring, allowing maintenance without forcing or tool-induced stress on the assembled structure.
3Ease of repair
If users carry tools for disassembly, then complete maintenance is possible, but user mobility is reduced
Solution Approach 1:
The disassembly capability is extracted from the tool set and integrated directly into the recoil group structure through the manual locking block mechanism. Users no longer need to carry external tools for maintenance, as the firearm itself provides the necessary disassembly function through its built-in locking mechanism.
