Dynamically Balanced Rifle Trigger for Drop-Safe Firing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rifle triggers are prone to negligent discharge and trigger slap due to movement caused by blunt forces, such as during drop tests, which is undesirable and poses safety risks.
Innovation Solution
A dynamically balanced trigger system with a center of gravity near the axis of rotation, incorporating specific design features like weight distribution and cutouts, to prevent accidental discharge and mitigate trigger slap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the trigger system uses conventional design without dynamic balancing, then the structure is simpler and easier to manufacture, but the trigger is prone to movement during drops causing negligent discharge
Solution Approach 1:
The trigger system employs dynamic balancing by positioning the center of gravity of the trigger assembly at or near the axis of rotation. This counterbalancing approach eliminates unwanted movement during drops by creating a stable rotational axis, preventing negligent discharge while maintaining structural integrity without requiring additional complex counterweight components.
Solution Approach 2:
The patent modifies geometric parameters of the trigger components, including the shape, weight distribution, and dimensional relationships between the trigger, disconnector, and hammer. These parameter changes optimize the center of gravity positioning and mass distribution to achieve dynamic balance, reducing sensitivity to blunt forces while maintaining operational functionality.
2Ease of manufacture
If the trigger components have conventional geometry, then manufacturing is easier, but trigger slap occurs during hammer re-cocking
Solution Approach 1:
The trigger system applies local quality modifications by optimizing specific geometric features of individual components. The trigger body, disconnector, and hammer each have tailored dimensional relationships and surface characteristics that reduce trigger slap during hammer re-cocking. These localized geometric optimizations minimize harmful movements without requiring complete redesign of the entire trigger system.
3Reliability
If the trigger is designed to be sensitive for accurate firing, then shooting precision is improved, but the trigger becomes more vulnerable to movement during drop tests
Solution Approach 1:
The dynamic balancing design positions the center of gravity at the rotational axis, creating a stable configuration that resists blunt force movements during drops. This stability mechanism operates independently of the trigger's firing sensitivity, allowing the system to maintain both drop resistance and operational sensitivity through proper geometric design of the balanced components.

AI summary
A dynamically balanced trigger system for a firearm. The dynamically balanced trigger has a specific design, orientation, weights, and cutouts such as to provide a balanced trigger, where the chances of accidental discharge due to drops, shocks, and impacts are dramatically reduced. Unlike other triggers, the dynamically balanced trigger system has a trigger with a center of gravity near the center point of the trigger, which weights the trigger components against itself to prevent movement, such as may be caused by dropping the firearm, thereby helping prevent an unintentional discharge of the firearm.
