Solution Overview
Problem
Existing trigger mechanisms for firearms are often complicated, unreliable, and costly to produce, necessitating improvements for enhanced performance and simplicity.
Innovation Solution
A redesigned trigger mechanism comprising a single stage trigger system with a trigger, trigger element, hammer element, disconnector, and associated springs, which provides a straightforward resistance profile for consistent firearm discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional trigger mechanism with multiple components (hammer, hammer spring, trigger, trigger spring, disconnector, disconnector spring) is used, then the firearm can be operated, but the mechanism becomes complicated and expensive to produce
Solution Approach 1:
The patent combines the hammer and trigger elements into a single integrated trigger assembly that moves as one unit. The trigger member integrates both the trigger function and hammer function, eliminating the need for separate hammer and trigger components while maintaining the firing mechanism's reliability through a unified structural design
2Ease of manufacture
If a traditional trigger mechanism with multiple pins and apertures is used, then the firearm can be assembled, but the manufacturing cost increases
Solution Approach 1:
The integrated trigger assembly requires fewer pins and mounting points compared to separate hammer and trigger components. By combining multiple functions into one piece, the patent reduces the number of assembly steps and fasteners needed, thereby lowering manufacturing complexity and cost
3Ease of operation
If a multi-stage trigger system is used, then the firearm can provide varied resistance, but the trigger pull becomes inconsistent and requires more user effort
Solution Approach 1:
The patent employs a single-stage spring system that provides a consistent linear resistance throughout the trigger pull. By using a progressive spring design with optimized coil spacing and wire diameter, the trigger delivers a uniform force profile, ensuring consistent discharge timing and reducing the total force required compared to multi-stage systems
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 new trigger mechanism offers improved reliability, reduced complexity, and cost-effectiveness by providing a single stage resistance that ensures consistent firearm discharge with minimal user effort.
Implementation Method 1
a trigger spring, positioned within the trigger element, configured to provide a single stage resistance to movement of the trigger element
