Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handguns are complex and costly to manufacture, lacking simplicity in design and production processes.
Innovation Solution
A fully automatic handgun design featuring a U-shaped breech block and sheet metal components, including a barrel mount, breech, and trigger mechanism, allowing for easy assembly and cost-effective production using stamped and bent sheet metal parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional handgun designs are used, then manufacturing complexity and cost increase, but manufacturing simplicity and cost-effectiveness decrease
Solution Approach 1:
The handgun is divided into distinct modular components including a barrel assembly, trigger assembly, magazine assembly, and frame. Each component can be manufactured separately using standardized processes and assembled through simple fastening operations, reducing overall manufacturing complexity while maintaining functional integrity
Solution Approach 2:
The trigger assembly serves multiple functions: it releases the firing mechanism, controls the firing sequence, and can be configured for different firing modes (single-shot, double-shot, automatic). This multi-functionality reduces the need for separate control mechanisms, simplifying the overall design while maintaining operational versatility
2Ease of manufacture
If traditional handgun designs are used, then manufacturing cost increases, but cost-effectiveness decreases
Solution Approach 1:
By segmenting the handgun into standardized modules (barrel, trigger, magazine, frame), each can be produced using efficient, scalable manufacturing processes. This modularity enables batch production and assembly line techniques, significantly reducing per-unit costs while maintaining quality standards
Solution Approach 2:
The design allows for parameter variations in different components (material selection, dimensional tolerances, finish requirements) based on functional needs rather than uniform high-specification manufacturing throughout. This selective parameter optimization reduces overall production costs while maintaining necessary performance levels
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enables the production of a cost-effective, simplified handgun mechanism that is easy to manufacture and assemble, while maintaining reliable automatic firing functionality.
Implementation Method 1
Pulling the trigger releases the slide and moves it forward towards the barrel by a spring
Implementation Method 2
The mass inertia causes the breech to essentially hold the cartridge case in the cartridge chamber until the bullet has left the barrel
Implementation Method 3
The cartridge case and breech are then pushed backwards by the gas pressure until the breech is caught again
