Handgun Breech Device With Internally Mounted Functional Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high machining costs associated with producing internal functional surfaces in breech devices for handguns result in elevated production costs for these devices.
Innovation Solution
A breech device design featuring a main functional region as a compact unit that can be securely anchored in a pre-defined position within the breech device, allowing for assembly from separately producible components, including plastics materials, which reduces manufacturing expenses and enables the use of morphologically structured designs at lower costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If internal functional surfaces are produced with high machining precision in the breech device, then functional reliability is improved, but manufacturing costs increase significantly
Solution Approach 1:
The breech device is divided into separate components: the breech block and the functional element. The functional element is produced separately with integrated functional surfaces, then assembled into the breech block. This segmentation allows the functional element to be manufactured using cost-effective processes like injection molding while maintaining high functional reliability through precise integration into the breech block.
2Manufacturing precision
If morphologically structured internal functional guiding surfaces are produced in the breech device, then functional performance is improved, but machining complexity and costs increase
Solution Approach 1:
The complex morphologically structured functional surfaces are extracted from the breech block and integrated into a separate functional element. This functional element can be produced using injection molding or other efficient processes that naturally create complex geometries without expensive machining operations, thereby reducing machining complexity while maintaining manufacturing precision.
Solution Approach 2:
The manufacturing method for the functional surfaces is changed from traditional precision machining to processes like injection molding that are better suited for producing complex morphologies. This parameter change in the manufacturing process allows for cost-effective production of precisely shaped functional surfaces.

AI summary
A breech device (100) for a handgun has an impact base (120) in a central recess (110) in said breech device (100). The impact base (120) is in the form of a front end face of an impact-base member (160) in the central recess. A main functional region (150) is between said impact base (120) and a rear end face (140) of said breech device. At least one percussion member (300) for firing a cartridge and also a surface of a cartridge slide (211) are in the main functional region (150). The surface of the cartridge slide (211) is adapted to abut cartridges mounted in a magazine (100) in a neutral position of the breech device.
