Problem
Bump firing a semi-automatic firearm using freehand techniques is difficult to master and requires precise control, making it inconsistent and challenging for operators to achieve rapid-fire successions without elaborate accessories.
Innovation Solution
A rapid-fire accessory for semi-automatic firearms, comprising a trigger guard mount and trigger actuator, which attaches to the firearm's trigger guard, allowing for sliding movement and engaging the trigger to facilitate consistent and rapid firing without the need for elaborate accessories or modifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If freehand bump firing technique is used, then rapid-fire capability is achieved, but operational difficulty and learning curve increase significantly
Solution Approach 1:
The patent introduces a bump fire accessory as an intermediary device between the operator and the firearm. This accessory includes a trigger guard mount that attaches to the firearm's trigger guard and a trigger actuator that engages the trigger, serving as a mechanical mediator that translates recoil energy into trigger actuation without requiring complex freehand techniques from the operator.
Solution Approach 2:
The bump fire accessory utilizes the firearm's own recoil energy to automatically actuate the trigger for subsequent shots. The trigger actuator is positioned and configured so that recoil movement of the firearm directly drives the actuator to release the trigger, creating a self-service system where the firearm's natural recoil performs the work of trigger manipulation.
2Productivity
If freehand bump firing technique is used, then rapid-fire capability is achieved, but consistency and reliability decrease
Solution Approach 1:
The trigger actuator serves as a reliable intermediary mechanism that consistently translates recoil energy into trigger actuation. Unlike freehand techniques that depend on operator skill and timing, the mechanical actuator provides a consistent geometric relationship between recoil movement and trigger release, ensuring reliable and consistent rapid-fire performance.
Solution Approach 2:
The patent modifies the operational parameters by introducing a fixed geometric relationship through the trigger actuator. The actuator's position, engagement point on the trigger, and movement path are all fixed parameters that ensure consistent trigger actuation regardless of operator variability, thereby improving firing consistency and reliability.
3Productivity
If elaborate accessories or modifications are used, then rapid-fire capability improves, but device complexity increases
Solution Approach 1:
The bump fire accessory is segmented into distinct functional components: a trigger guard mount for attachment and a trigger actuator for trigger manipulation. This segmentation allows each component to perform its specific function independently while maintaining overall simplicity, avoiding the need for elaborate integrated systems.
Solution Approach 2:
The trigger guard mount is designed to attach to the firearm's existing trigger guard, utilizing an existing structural element rather than requiring separate mounting hardware or modifications. The accessory leverages the firearm's natural recoil movement and existing trigger guard structure, reducing the need for additional components and simplifying the overall device design.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easier and more consistent rapid-fire capabilities by guiding the recoil energy for faster discharge sequences, improving operational ease and reducing the learning curve compared to freehand techniques.
Implementation Method 1
Bump firing is a technique of firing a semi-automatic firearm using the recoil energy from firing the weapon to rapid-fire faster than what an operator could achieve by repeated finger pulls

AI summary
Devices, systems, and methods of manufacturing are disclosed with regard to a rapid-fire accessory for a semi-automatic firearm. The rapid-fire accessory may include a trigger guard mount and a trigger actuator. The trigger guard mount may attach the rapid-fire accessory to the semi-automatic firearm. The trigger guard mount may include a mounting channel for receiving a trigger guard of the semi-automatic firearm. When mounted in the mounting channel, the trigger guard guides a sliding movement of the trigger guard mount forward and rearward relative to the trigger guard. The trigger actuator may engage a trigger of the semi-automatic firearm. The trigger actuator may be fixed relative to the mounting channel and configured to pull the trigger when the trigger guard slides forward in the mounting channel.
