Solution Overview

Problem

Current modular systems for firearms are proprietary, limiting customization as they only function with specific grip frames and slide assemblies, restricting compatibility across different sizes, colors, and calibers.

Innovation Solution

A modular trigger control unit designed to be removably installed on various grip frames and slide assemblies, secured by a locking block and pin system, allowing compatibility with different firearm configurations while displaying identification markings, enabling customization across semi-automatic and full-automatic firearms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If proprietary modular systems are used, then the trigger control unit is designed to function only with specific grip frames and slide assemblies, but this limits customization and compatibility across different sizes, colors, and calibers

Engineering Contradiction:
ImprovecompatibilityVSAvoidcustomization
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The trigger control unit is designed with universal compatibility features that allow it to function with multiple grip frames and slide assemblies of different sizes, colors, and calibers. The locking block and pin system provides a standardized interface that can accommodate various firearm configurations, enabling one trigger control unit to serve multiple functions across different firearm platforms.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If a standardized locking block and pin system is used, then the trigger control unit can be secured to various grip frames, but this requires a secure mounting mechanism that prevents unintended removal

Engineering Contradiction:
ImprovecompatibilityVSAvoidmounting mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mounting mechanism is segmented into distinct functional components: a locking block that interfaces with the grip frame, locking block pins that secure the assembly, and a protruding tab that engages with a recess on the beavertail portion. This segmentation allows each component to perform its specific function independently while contributing to the overall secure mounting capability.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If the trigger control unit is designed for easy removal and installation, then customization is enhanced, but this may compromise the secure attachment and potential safety

Engineering Contradiction:
Improveremoval and installationVSAvoidsecure attachment
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The locking block pins are designed to be extractable from the assembly, allowing the trigger control unit to be removed from the grip frame. The pins can be taken out to release the locking block from the grip frame recess, enabling easy removal and reinstallation while maintaining secure attachment when the pins are in place.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A modular trigger control unit Is configured to be removably installed on a grip frame of a firearm and includes a locking block and a locking block pin. The trigger control unit has a protruding tab protruding rearward. The locking block includes slide rails extending forward, with each slide rail of the pair of slide rails having a flat wall extending downward with respect to the grip frame when the trigger control unit is installed on the grip frame. The trigger control unit is secured to the grip frame by: (1) the protruding tab received in a recess on an interior wall of a beavertail portion of the grip frame; and (2) the locking block pin traversing through a through hole on each flat wall such that removal of the trigger control unit from the grip frame requires removal of the locking block pin.
