Modular Trigger Control Unit with Intermediary Rail Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current modular systems for firearms, particularly pistols, are proprietary and prone to stress issues due to recoil forces, limiting their compatibility with different slide assemblies and grip frames.
Innovation Solution
A modular trigger control unit and rail module design that allows for installation on various slide assemblies and grip frames of different sizes, colors, and calibers, with the rail module securing the trigger control unit to the grip frame, reducing stress and enhancing customization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a trigger control unit is secured to the grip frame by a pin in existing modular systems, then the trigger control unit can be attached to the grip frame, but under repeated recoil forces a significant amount of stress is exerted on the pin leading to reliability issues
Solution Approach 1:
The attachment system is divided into multiple components: a trigger control unit, a grip frame, and an intermediary rail module with engagement features. This segmentation distributes the stress from recoil forces across multiple attachment points and components rather than concentrating it on a single pin, thereby improving reliability while reducing stress on individual elements.
Solution Approach 2:
A rail module is introduced as an intermediary component between the trigger control unit and the grip frame. This rail module includes engagement features that interface with both the trigger control unit and the grip frame, serving as a mediator that distributes and manages the stresses generated during recoil, preventing excessive stress concentration on any single attachment point.
2Adaptability or versatility
If proprietary modular systems are used for pistols, then customization is enabled, but compatibility is limited to specific vendor's grip frames and slide assemblies
Solution Approach 1:
The rail module is designed with engagement features that can interface with multiple different slide assemblies and grip frames from various vendors. By creating a universal intermediary component that can adapt to different configurations, the system enables cross-compatibility between trigger control units and various firearm components, transforming a proprietary system into a universal one that maintains versatility while reducing vendor-specific limitations.

AI summary
.An apparatus implementable on a firearm includes a grip frame, a slide assembly, a trigger control unit, and a rail module. The trigger control unit is removably receivable in the grip frame and installed between the grip frame and the slide assembly such that, when operated, the trigger control unit causes firing of one or more rounds of ammunition. The rail module is configured to be installed between the trigger control unit and the grip frame to aid in securing the trigger control unit to the grip frame.
