Modular Trigger Control Unit with Universal Grip-Frame Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current modular systems for pistols are proprietary, limiting the customization of fire control units to specific grip frames and slide assemblies, restricting compatibility and flexibility.
Innovation Solution
A modular trigger control unit that can be removably installed on various grip frames and slide assemblies of different sizes, colors, and calibers, secured by a locking block, pins, and physical features, allowing for customizable firearm configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If proprietary modular systems are used for pistols, then the trigger control unit is designed to function only with specific proprietary grip frames and slide assemblies, but this limits customization and compatibility across different firearm configurations
Solution Approach 1:
The trigger control unit is designed with universal mounting features including a protruding tab that fits into a recess on the beavertail portion, a locking block with slide rails, and physical features that mate with corresponding features on the grip frame. This universal design allows the same trigger control unit to be installed on multiple different grip frames and slide assemblies of various sizes, colors, and calibers, eliminating the need for proprietary-specific designs while maintaining secure attachment and proper function
2Adaptability or versatility
If a modular trigger control unit is designed to fit multiple grip frames and slide assemblies, then customization options increase, but the securing mechanism must accommodate various sizes and configurations
Solution Approach 1:
The securing mechanism is divided into distinct functional components: a protruding tab for rearward engagement with a recess on the beavertail portion, a locking block with slide rails for lateral positioning, pins for rigid attachment, and mating physical features. This segmentation allows each component to perform its specific function independently while working together as a unified system that accommodates various grip frame and slide assembly configurations without complicating the installation process
3Reliability
If the trigger control unit uses multiple securing features (protruding tab, locking block, pins, physical features), then the attachment is more secure, but the number of components increases
Solution Approach 1:
Multiple securing functions are merged into an integrated trigger control unit assembly where the protruding tab, locking block with slide rails, pins, and mating physical features work together as a unified securing system. This merging provides robust attachment security through redundant securing mechanisms while avoiding the complexity of separate, independent securing devices. The components are designed to install together in a coordinated manner, reducing the overall complexity compared to using multiple separate securing mechanisms

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 pin configured to traverse through both the trigger control unit and the grip frame. 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 or upward 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; (2) the pin; and (3) one or more first physical features on the trigger control unit mating with one or more second physical features on the grip frame.
