Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional firearm frame locking systems are complex, prone to pin loss, and require a lengthy disassembly and reassembly process, posing a significant burden on users.
Innovation Solution
A firearm frame locking system featuring an upper and lower frame that slide into each other via projections and grooves, with a double-arm swinging lever and preloaded compression spring, ensuring secure attachment and quick disassembly by using projections and grooves along the longitudinal axis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional pin-based locking systems are used to connect firearm frame groups, then the firearm can be assembled and disassembled, but the process becomes complex and time-consuming
Solution Approach 1:
The invention extracts and eliminates the pin component from the locking system. Instead of using pins that must be inserted and secured, the design employs a direct sliding connection between frame groups where the locking mechanism is integrated into the frame structure itself, removing the separate pin element that complicates the assembly process
Solution Approach 2:
The locking function is merged with the frame structure itself. The sliding connection between upper and lower frame groups incorporates the locking mechanism directly into the frame design, combining what were previously separate components (frame groups and locking pins) into an integrated system where the frames lock together through their own structural features
2Reliability
If pins are used to connect firearm frame groups, then the groups can be secured together, but the pins may be lost during disassembly
Solution Approach 1:
The locking function is merged with the frame structure itself. The sliding connection between upper and lower frame groups incorporates the locking mechanism directly into the frame design, combining what were previously separate components (frame groups and locking pins) into an integrated system where the frames lock together through their own structural features

Function Achieved in This Case
This design simplifies the disassembly and reassembly process, prevents pin loss, and reduces the time required for firearm maintenance by providing a secure locking mechanism that allows for efficient disassembly and reassembly.
Implementation Method 1
A preloaded compression spring may be placed between the second arm of the double-arm swinging lever and the rib of the front part of the lower frame

AI summary
A firearm frame locking system locks a two-part firearm frame. This is achieved by a firearm frame locking system that includes an upper frame and a lower frame that slide into each other by means of projections that fit into grooves in both the upper frame and the lower frame. In the lower frame, a double-arm lever is located along the longitudinal axis of the firearm. One arm of the double-arm lever extends at least partially into/through a vertical hole in a horizontal rib of the lower frame. A second arm of the double-arm lever ends in the opposite position to a projection in the upper frame. A spring is placed between the horizontal arm and the rib.
