Bi-directional Trigger Assembly with Selector Switch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional firearm trigger assemblies are limited to rearward trigger pull, which may not be natural or convenient for all users, restricting optimal performance and accuracy.
Innovation Solution
A bi-directional trigger assembly that allows the trigger to be pulled both rearward and forward, featuring a trigger bar with a slot, a selector switch, a disconnector, a hammer, and a linkage with protrusions that facilitate both directions of trigger movement, enabling the hammer to release and fire a round regardless of the pull direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the trigger assembly is designed for rearward trigger pull only, then the structure is simple and reliable, but the ease of operation is reduced for users who prefer forward pull
Solution Approach 1:
The trigger assembly is designed with dynamic functionality to adapt between two operational modes (rearward pull and forward pull) based on user preference. The selector switch enables the system to change its operational state, allowing the trigger bar and linkage to function in either direction, thus improving ease of operation without permanently increasing structural complexity.
Solution Approach 2:
The trigger assembly is designed to perform multiple functions by enabling both rearward and forward trigger pulls. The selector switch mechanism allows the same physical assembly to serve dual purposes: conventional rearward operation and alternative forward operation, making the device universal and adaptable to different user preferences without requiring separate assemblies.
2Adaptability or versatility
If the trigger assembly allows bidirectional operation, then the adaptability is improved, but the device complexity increases due to additional components
Solution Approach 1:
The trigger assembly incorporates a selector switch that enables dynamic adaptation between rearward and forward pull modes. This allows the system to change its operational characteristics based on user preference, significantly improving adaptability. The selector switch mechanism, while adding a component, integrates seamlessly with the existing trigger bar and linkage structure.
Solution Approach 2:
The trigger assembly is segmented into distinct functional components: the selector switch, trigger bar, disconnector, and linkage. This segmentation allows the adaptability feature to be isolated to specific components (selector switch and linkage positioning) rather than requiring complete redesign of the entire assembly, thereby managing complexity through modular design.
3Ease of operation
If the trigger assembly is designed for unidirectional pull, then the manufacturing precision requirements are lower, but the ease of operation is reduced for users preferring the opposite direction
Solution Approach 1:
The trigger assembly uses a selector switch to dynamically adjust the operational direction, allowing users to choose between rearward and forward pull based on their preference. This dynamic capability ensures that manufacturing precision is optimized for each specific mode while maintaining overall ease of operation for all users, regardless of their preferred pulling direction.
Solution Approach 2:
The linkage component features localized quality variations with specific protrusions positioned at predetermined locations. These local structural features are precisely manufactured to engage with corresponding elements in either the forward or rearward direction, ensuring that manufacturing precision is applied selectively to the critical engagement points rather than the entire assembly.
4Adaptability or versatility
If the trigger assembly allows forward pull in addition to rearward pull, then the adaptability is improved, but the device complexity increases due to additional linkages and protrusions
Solution Approach 1:
The trigger assembly is divided into modular components: selector switch, trigger bar, disconnector, and linkage with specific protrusions. This segmentation allows the forward pull capability to be added as a distinct functional module rather than requiring complete redesign, managing complexity through organized modularity while achieving improved adaptability.
Solution Approach 2:
The selector switch enables the trigger assembly to dynamically switch between two operational configurations. In one configuration, the linkage protrusions engage for rearward pull; in the other, they engage for forward pull. This dynamic reconfiguration allows bidirectional operation without requiring duplicate complete assemblies, thereby improving adaptability while controlling the increase in device complexity.

AI summary
A bi-directional trigger assembly comprises a trigger having a first protrusion. A trigger bar having a slot is coupled to the trigger. A selector switch is positioned adjacent the rear end of the trigger bar. A disconnector is accommodated within the slot. A hammer is provided adjacent the front end of the trigger bar, wherein the hammer is configured for operable coupling to the trigger bar and the disconnector. A linkage is configured for fitment adjacent the trigger bar within the fire arm, wherein the linkage includes a second protrusion positioned adjacent a top edge of the trigger bar. The linkage further includes a third protrusion wherein the third protrusion abuts the first protrusion for displacing the linkage downward when a forward force is applied on the trigger, thereby causing the second protrusion to exert a downward acting force adjacent the front end of the trigger bar.
