Subcompact Pistol Grip Protrusions for Stable Magazine Feeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing semi-automatic pistols face issues of magazine movement within the grip, leading to jamming and ejection problems, particularly with increased bullet capacity, which existing solutions have not adequately addressed.
Innovation Solution
The pistol features flat protrusions on the inner surface of the grip to secure the magazine, specifically a rear and front protrusion, ensuring proper fit and preventing magazine movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the magazine capacity is increased to hold more bullets, then the ammunition storage capability is improved, but the magazine becomes more prone to movement and jamming within the grip
Solution Approach 1:
The patent applies local quality by adding flat protrusions at specific locations on the inner surface of the grip to create localized contact points. These protrusions are positioned to engage with corresponding flat surfaces on the magazine, providing targeted stabilization without altering the overall magazine structure or capacity. This localized modification prevents magazine movement and feeding issues while maintaining the increased bullet capacity.
2Quantity of substance
If the magazine capacity is increased to hold more bullets, then the ammunition storage capability is improved, but the magazine stability within the grip deteriorates
Solution Approach 1:
