Trigger Assembly With Secondary Disconnector for Dual-Release Firing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Triggers that actuate and fire a round upon both pull and release present challenges such as light primer strikes and unexpected trigger states, especially when integrated into existing firearm frames.
Innovation Solution
A trigger assembly with a housing and a trigger bar guide that moves along a ramp within the housing, causing a striker to be released upon trigger pull and release, utilizing a secondary disconnector mechanism for reliable firing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a trigger assembly is integrated into an existing firearm frame, then the firearm can be upgraded with dual-release capability, but the complexity of the trigger mechanism increases
Solution Approach 1:
The trigger mechanism is segmented into distinct functional components: a trigger bar guide for managing trigger movement, a secondary disconnector for releasing the striker on trigger release, and a ramp structure for guiding the trigger bar guide's path. This segmentation allows each component to perform its specific function while maintaining overall system reliability without excessive complexity.
Solution Approach 2:
The trigger bar guide acts as an intermediary element between the trigger and the striker. It mediates the interaction by first guiding the trigger's movement and then working with the secondary disconnector to reliably release the striker, ensuring proper sequence of events without direct complex interactions between the trigger and striker.
2Reliability
If a secondary disconnector is added to ensure reliable firing on trigger release, then firing reliability improves, but the number of components increases
Solution Approach 1:
The secondary disconnector is merged with the trigger bar guide assembly, where the secondary disconnector is positioned to interact with the trigger bar guide during its movement along the ramp. This merging reduces the number of separate components while maintaining the dual-release functionality, as the secondary disconnector works in conjunction with the existing trigger bar guide rather than operating as a completely separate mechanism.

AI summary
A trigger assembly for a firearm includes a housing with an opening adapted to receive a trigger bar guide portion of a trigger bar. The opening includes a ridge that extends downward from an upper surface of the opening. The trigger bar guide is forced downward in the opening by a connector as the trigger is pulled to cause a first disconnect of a striker resulting in a first firing. Upon release of the trigger the trigger bar guide moves upward and upon return to a released position is forced downward to cause a secondary disconnect of striker resulting in a second firing.
