Segmented Pistol Slide Design for Reduced Material Waste
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing manufacturing process for pistol slides results in significant metal waste, as more than half of the metal block is discarded when forming the recoil spring housing, and the interdependence of parts complicates the manufacturing of both the upper and lower parts.
Innovation Solution
The pistol slide is designed as two separate parts, an upper part to guide the barrel and a lower part to guide the recoil spring system, which are manufactured independently and coupled together using rigid or non-rigid attachment methods, allowing for efficient production and assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the slide is manufactured as a single solid unit by machining a metal block, then the structural integrity and robustness of the slide is improved, but significant metal waste occurs (more than half of the metal block is discarded)
Solution Approach 1:
The slide is divided into two separate parts: an upper part that guides the barrel and a lower part that guides the recoil spring guide rod. Each part is manufactured independently from smaller metal blocks, reducing overall material waste while maintaining the structural integrity of the complete slide assembly.
2Stability of the object's composition
If the slide is manufactured as a single solid unit, then the robustness of the slide is improved, but the manufacturing process becomes more complex due to the interdependence of upper and lower parts
Solution Approach 1:
The slide is segmented into an upper part and a lower part that are manufactured independently. This segmentation simplifies the manufacturing process by eliminating the interdependence issues that arise when machining a single solid block, while the parts are subsequently assembled to form the complete slide structure.
Solution Approach 2:
The patent introduces an intermediary connection mechanism between the upper and lower parts, such as rails, grooves, or other attachment methods, that allow the parts to be joined while maintaining the necessary structural stability and functionality during operation.
3Strength
If the slide is manufactured as a single solid unit, then the structural strength is improved, but the manufacturing time and productivity are reduced due to the need to machine both parts from one block
Solution Approach 1:
The slide is divided into separable upper and lower parts that can be manufactured simultaneously in parallel processes, eliminating the sequential machining requirements of a single-block approach and thereby improving manufacturing efficiency and productivity.
