Elastomer Trigger Shock Absorber for Firearm Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearms suffer from accuracy and stability issues due to the abrupt transfer of kinetic energy from the trigger release to the frame assembly, leading to destabilizing shock and reduced repeatability, which is not effectively addressed by traditional methods of lightening the trigger pull force as it compromises safety.
Innovation Solution
A trigger energy absorption device using a dampening elastomer is placed between the trigger and the frame assembly to absorb the energy of the trigger pull and shock, preventing abrupt energy transfer, thereby maintaining safety while improving accuracy and repeatability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the trigger pull force is lightened to improve accuracy, then the trigger pull becomes lighter and easier to pull, but the safety of the firearm is compromised and accidental firing may occur
Solution Approach 1:
The patent introduces a trigger spring as an intermediary element between the trigger and the sear mechanism. This spring absorbs the kinetic energy of the trigger during its movement, mediating the force transmission. The spring allows the trigger to move smoothly while maintaining sufficient force for safe sear engagement, thus improving accuracy without compromising safety by preventing accidental disengagement.
2Productivity
If the trigger releases the sear abruptly to enable rapid firing, then the firing speed increases, but the shock transfer to the frame assembly causes destabilizing impact and reduces accuracy
Solution Approach 1:
The patent applies beforehand cushioning by pre-installing a trigger spring in the trigger assembly before operation. This spring is specifically designed to cushion the impact and absorb the shock generated when the trigger releases the sear. By having this cushioning mechanism in place beforehand, the abrupt release can occur rapidly for high firing speed, while the spring simultaneously absorbs the destabilizing shock to maintain accuracy.
Solution Approach 2:
The trigger spring acts as an intermediary between the trigger mechanism and the frame assembly. It mediates the force transmission by absorbing and dissipating the shock energy that would otherwise be directly transferred to the frame. This allows rapid sear release for high productivity while preventing the harmful shock transfer that would degrade accuracy.
3Device complexity
If the trigger is designed to engage the sear directly without energy absorption to simplify the mechanism, then the device complexity is reduced, but the shock load transfer destabilizes the firearm frame and reduces accuracy
Solution Approach 1:
The trigger spring serves as a simple intermediary component that is integrated into the existing trigger assembly. It adds minimal complexity to the overall mechanism while effectively absorbing shock loads. The spring is positioned between the trigger and the sear engagement point, providing energy absorption without requiring complex additional mechanisms, thus maintaining simplicity while improving accuracy.
Solution Approach 2:
The patent changes the physical parameters of the trigger assembly by introducing an elastic element (the spring) that can deform and store energy. This parameter change allows the system to absorb shock loads dynamically rather than transmitting them rigidly. The spring's elastic properties enable it to modify the force transmission characteristics, reducing shock transfer to the frame while maintaining the overall simplicity of the mechanism.

The device enhances firearm accuracy and repeatability by absorbing kinetic energy, reducing shock transfer to the frame assembly, and shortening trigger reset distance, without compromising safety, and is adaptable to various firearm types.
Implementation Method 1
a dampening energy absorbing element that fits between the back side of the firearm trigger and the trigger guard... the trigger energy absorption device uses a dampening energy absorbing element that fits between the back side of the firearm trigger and the trigger guard... the rear of the trigger contacts the media and begins compressing it... the after firing release trigger motion is absorbed by the media which prevents the shock load transfer
Implementation Method 2
a dampening energy absorbing element... dampening trigger shock force transfer to the frame assembly... the after firing release trigger motion is absorbed by the media which prevents the shock load transfer of the destabilizing energy to the firearm frame assembly

AI summary
An elastomer shock absorber for the trigger assembly of a firearm utilizing an elastomer shock absorber positioned between a moving part of the trigger assembly and the frame assembly. Adhesive mounting of the elastomer to the back of the trigger or positioning the elastomer internal to the frame assembly both provide significant reductions in the shock transfer of trigger energy to the gun body, thereby increasing the accuracy of the firearm.
