Trigger Relocation Assembly for Firearm Configuration Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern sporting firearms lack a versatile and ergonomic solution for relocating the trigger to improve handling and convert between standard and bullpup configurations without modifying the firearm.
Innovation Solution
A modular trigger relocation assembly that includes a frame enclosing the firearm's trigger, an assembly trigger positioned forward, an asymmetrical transfer bar for one-to-one movement transfer, and bushings to guide the transfer bar, allowing reversible conversion between configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the trigger is relocated forward to improve ergonomics and enable bullpup configuration conversion, then the ease of operation and adaptability are improved, but the device complexity increases due to the need for transfer bars, bushings, and framing mechanisms
Solution Approach 1:
The trigger relocation assembly is divided into separate functional components: a frame that encloses the original trigger, an assembly trigger positioned forward, a transfer bar mechanism for movement transfer, and bushings for guidance. This segmentation allows each component to perform its specific function while maintaining overall system manageability and ease of installation.
Solution Approach 2:
The transfer bar acts as an intermediary element that mechanically couples the forward-positioned assembly trigger to the original firearm trigger. This intermediary component enables the relocation function by transferring movement from the new trigger position to the original trigger mechanism without requiring direct modification of the firearm's core components.
2Adaptability or versatility
If a modular trigger relocation assembly is used to enable reversible conversion between configurations, then the adaptability is improved, but the device complexity increases due to multiple components including frame, transfer bar, and bushings
Solution Approach 1:
The trigger relocation assembly is designed as a universal modular unit that can be attached to and removed from the firearm, enabling conversion between standard and bullpup configurations. The assembly functions as a complete, self-contained system that can be installed or removed without permanent modification to the firearm, providing reversible adaptability.
Solution Approach 2:
The assembly incorporates movable components including the transfer bar that can move within guided bushings, allowing dynamic adjustment and operation. The entire assembly can be dynamically installed or removed from the firearm, providing flexibility and reversible configuration change rather than a fixed permanent modification.
3Ease of operation
If the assembly trigger is positioned forward of the original trigger, then the ergonomics and handling are improved, but the structural complexity increases due to the framing and transfer mechanisms required
Solution Approach 1:
The transfer bar is designed as an asymmetrical component with a specific geometry that allows it to couple the forward-positioned assembly trigger to the original trigger in a one-to-one movement relationship. The asymmetrical design enables the transfer function while maintaining a compact structure that minimizes the size and complexity of the required framing.

AI summary
A trigger relocation assembly for a modern sporting firearm includes a frame enclosing a trigger of the modern sporting firearm, an assembly trigger within the frame, the assembly trigger positioned forward of the trigger, an asymmetrical transfer bar coupled to transfer movement of the assembly trigger one-to-one to the trigger, and a plurality of bushings. The bushings are configured to guide the transfer bar within the frame.
