Elastomer Trigger Energy Absorber for Firearm Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearms suffer from accuracy and repeatability issues due to the abrupt transfer of kinetic energy from the trigger release to the frame assembly, leading to instability and potential accidental firing when attempting to lighten the trigger pull to improve accuracy.
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 and maintaining stability during firing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the trigger pull weight is lightened to improve accuracy, then the trigger pull force is reduced, but the safety is degraded causing potential accidental firing
Solution Approach 1:
The patent applies beforehand cushioning by placing an elastomeric material between the trigger and frame assembly that compresses during trigger pull. This cushioning element absorbs the kinetic energy of the trigger release, preventing abrupt energy transfer to the frame assembly. The elastomer is positioned to engage after sear release, cushioning the trigger's forward motion and eliminating the jarring impact that causes accuracy issues without requiring a lighter trigger pull, thus maintaining safety.
2Reliability
If the trigger pull weight is increased to improve safety, then the safety is improved, but the accuracy is degraded due to abrupt energy transfer causing frame assembly instability
Solution Approach 1:
The patent applies the intermediary principle by introducing an elastomeric material as a mediator between the trigger and frame assembly. This intermediary element absorbs the shock and kinetic energy from the trigger release, preventing direct transfer of energy to the frame assembly. The elastomer acts as a buffer that smooths out the energy transfer, eliminating the jarring impact that causes frame assembly instability and accuracy degradation, while allowing the trigger pull weight to remain at safe levels.
3Device complexity
If a traditional trigger mechanism is used without energy absorption, then the device complexity is low, but the accuracy and repeatability are degraded due to shock transfer
Solution Approach 1:
The patent applies parameter changes by modifying the physical state and energy absorption characteristics of the trigger assembly through the addition of an elastomeric material. The elastomer changes the way energy is absorbed and dissipated in the trigger system, transforming the abrupt kinetic energy release into a controlled compression and release cycle. This parameter change in energy absorption behavior improves accuracy and repeatability without significantly increasing device complexity, as the elastomer is a simple component that integrates into the existing trigger mechanism.

Implementation Method 1
a dampening energy absorbing element that fits between the back side of the firearm trigger and the trigger guard
Implementation Method 2
The trigger energy absorption device can be adhesively mounted to a moving part of the trigger assembly or to an element of the frame assembly so that it absorbs the energy from the trigger moving element

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.
