Firearm Magazine Receiver Above Trigger Guard
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm designs face issues with length and convenience in loading cartridges due to the placement of the cartridge receptacle, particularly when it is located in front of or above the trigger guard, making it difficult to handle and install magazines.
Innovation Solution
The firearm design places the magazine receiver above the trigger guard and incorporates a side surface hole for easier magazine installation, reducing the firearm's length and improving handling by allowing direct access to the magazine receptacle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the cartridge receptacle is located in front of the trigger guard, then the firearm can be designed with a simpler structure, but the length of the firearm becomes long
Solution Approach 1:
The patent relocates the cartridge receptacle from a front-mounted position to a top-mounted position above the trigger guard. This dimensional change allows the receptacle to be accessed from above rather than from the front, thereby reducing the forward length of the firearm while maintaining structural simplicity.
2Length of moving object
If the magazine is placed above the trigger guard, then the firearm length is reduced, but the difficulty of placing cartridges increases
Solution Approach 1:
The patent introduces a side surface hole as an intermediary access point. This hole provides a dedicated pathway for inserting cartridges into the magazine, which is positioned above the trigger guard. The side hole acts as a mediator that facilitates easy cartridge loading from the side while the magazine remains in its compact top position.
3Length of moving object
If the magazine is located above the trigger guard, then the firearm length is reduced, but the handling convenience becomes very difficult and inconvenient
Solution Approach 1:
The side surface hole serves as an intermediary access mechanism that enables easy magazine and cartridge manipulation. By providing a dedicated side access point, the design allows users to quickly insert magazines and load cartridges without compromising the compact top-mounted position of the magazine, thus maintaining both short length and ease of handling.
4Ease of operation
If a side surface hole is added for magazine installation, then the ease of loading is improved, but the device complexity increases
Solution Approach 1:
The patent segments the access function by creating a dedicated side surface hole separate from the main body structure. This segmented approach allows the hole to serve as a specialized cartridge insertion pathway without requiring complex mechanisms or additional moving parts. The simple geometric feature of a side hole provides easy loading functionality with minimal added complexity.
