Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing firearms often have complex operating systems that rely on direct mechanical attachments between the trigger and firing mechanism, requiring multiple springs and additional mechanical systems, which can complicate functionality and reliability.

Innovation Solution

A firearm operating system featuring a central pivoting member within a housing, where the trigger's movement causes a finger to press against the central pivoting member, rotating it to simplify the operating system and reduce the number of springs and mechanical components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a direct and fixed mechanical attachment between the trigger and firing system is used, then the firing mechanism is reliable, but the device complexity increases and multiple springs are required

Engineering Contradiction:

Improvefiring mechanism reliabilityVSAvoidoperating system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the trigger and firing mechanism into a single integrated assembly where the trigger directly actuates the firing pin through a unified mechanical structure. This consolidation eliminates the need for separate springs and intermediate mechanical linkages, reducing overall device complexity while preserving reliable fire control through the integrated design.

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If multiple springs are used to operate the firearm, then the operating system is robust, but the quantity of components increases

Engineering Contradiction:

Improveoperating system robustnessVSAvoidnumber of springs

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent extracts and eliminates the multiple springs from the operating system by designing a direct mechanical actuation mechanism. The trigger assembly directly pushes the firing pin without requiring spring intermediaries, thereby reducing the quantity of components while maintaining operational robustness through the simplified direct-drive architecture.

Inventive Principle:

Principle #2Taking out (Extraction)

3Adaptability or versatility

If separate mechanical systems are used for releasing the slide and disassembling the firearm, then the functionality is comprehensive, but the device complexity increases

Engineering Contradiction:

Improveslide release and disassembly functionalityVSAvoidmechanical systems quantity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal trigger assembly that performs multiple functions: it controls the firing mechanism, releases the slide, and facilitates disassembly. This multi-functional design eliminates the need for separate mechanical systems for each operation, reducing device complexity while maintaining comprehensive functionality through the integrated trigger mechanism.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A firearm operating system includes a housing, a central pivoting member disposed within the housing, a trigger including a portion disposed within the housing and a portion extending outside the housing such that the portion of the trigger within the housing includes a hole and at least one finger that extends in a first direction from the hole. Due to movement of the trigger, the at least one finger presses against the central pivoting member to cause the central pivoting member to rotate.
