Adjustable Trigger Assembly for Firearm Hand Size Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Firearms often require customization to fit individual shooter hand sizes, particularly in the resting position of the trigger, which existing models fail to adequately address, leading to discomfort and reduced accuracy.
Innovation Solution
An adjustable trigger assembly that allows the resting position of the trigger to be customized by modifying the linkage connection points within the trigger body, enabling forward or rearward adjustment to accommodate different hand sizes, and potentially adjusting trigger travel distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the trigger position is fixed in standard firearms, then the manufacturing and design are simplified, but the fit and comfort for shooters with different hand sizes deteriorates
Solution Approach 1:
The trigger assembly incorporates adjustable components that allow the trigger resting position to be dynamically changed between multiple predetermined positions. The trigger body can be repositioned relative to the trigger guard along the trigger axis, enabling adaptation to different shooter hand sizes while maintaining a manageable structural complexity through standardized adjustment mechanisms.
Solution Approach 2:
The trigger assembly is divided into separable components including the trigger body, trigger guard, and linkage system. This segmentation allows independent adjustment of the trigger body position within the trigger guard while keeping other components standardized, thus improving adaptability without proportionally increasing overall device complexity.
2Ease of operation
If the trigger resting position is adjusted forward for shooters with larger hands, then the fit and comfort improve, but the trigger travel distance increases
Solution Approach 1:
The system provides discrete adjustment of the trigger resting position along the trigger axis to multiple predetermined positions. By changing the positional parameter of the trigger body relative to the trigger guard, shooters can optimize comfort while the linkage system compensates for travel distance variations through its geometric configuration.
Solution Approach 2:
The linkage system acts as an intermediary between the trigger body and the firing mechanism. It translates the adjusted trigger body position into appropriate hammer engagement, compensating for variations in trigger travel distance caused by different resting positions and maintaining consistent firing performance across all adjustment settings.
3Ease of operation
If the trigger resting position is adjusted rearward for shooters with smaller hands, then the fit and comfort improve, but the trigger travel distance decreases
Solution Approach 1:
The system enables adjustment of the trigger resting position to multiple predetermined positions along the trigger axis, including rearward positions for shooters with smaller hands. The linkage system's geometric parameters are designed to accommodate these position changes while maintaining adequate trigger travel for reliable firing across all adjustment settings.
Solution Approach 2:
The linkage system serves as a mediator that adapts the reduced trigger travel distance resulting from rearward position adjustment. Through its mechanical geometry, it ensures sufficient effective travel is transmitted to the hammer engagement point, compensating for the shorter physical displacement of the trigger body.

AI summary
The present disclosure provides a system and method for adjusting the normal resting position of a trigger for a firearm. The system and method allow for further customization of the fit of the firearm by moving the resting position of the trigger forward to accommodate shooters with larger hands and moving the resting position of the trigger rearward to accommodate shooters with smaller hands.
