Remote Trigger Mechanism for Stable Shooting Rest Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shooting rests for firearms are susceptible to undesirable movements relative to the operator during trigger operation, which can affect the stability and accuracy of the firearm.
Innovation Solution
A remote trigger activation system that connects to a firearm or bench/shooting rest, allowing for one-to-one force application to the trigger, resisting movement of the rest during firing, and includes features like fail-safe mechanisms and adjustable configurations to ensure precise and stable trigger activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a shooting rest is used to stabilize a firearm, then the firearm stability is improved, but the rest may be laterally displaced when the operator affects trigger operation
Solution Approach 1:
A remote trigger mechanism is introduced as an intermediary device between the operator and the firearm trigger. This mechanism allows the operator to actuate the trigger remotely without direct contact, thereby eliminating the lateral displacement problem while maintaining firearm stability. The remote trigger mechanism includes a trigger bar that can be actuated by the operator through a controlled motion path that does not interfere with the shooting rest stability.
2Ease of operation
If the operator directly operates the trigger, then the trigger activation is simple, but the rest experiences unwanted movement affecting accuracy
Solution Approach 1:
The trigger operation is segmented into two independent functions: trigger actuation and rest stabilization. The remote trigger mechanism handles trigger actuation while the shooting rest independently maintains stabilization. This segmentation allows each function to be optimized separately, ensuring both ease of operation and shooting accuracy are achieved without interference between the two functions.

AI summary
A remote trigger activation system for a firearm secured in a shooting rest includes a trigger-activation mechanism mountable to the rest or directly to the firearm and a remote manual trigger assembly coupled via flexible push-pull cable. The activation mechanism employs a cam or gear train configured with approximately 1:1 mechanical advantage to depress the firearm trigger while preserving tactile “pull” and “break” feel. A safety interlock biases the mechanism to a non-engaged state and includes a removable pin to block actuation in safe mode. Toolless, multi-axis adjustments (height, lateral offset, and fore-aft) and universal interfaces accommodate diverse platforms. A shooting rest stabilizer may include a base plate that captures a rear rest leg and three elongate, preloaded supports clamped to fixed supports or a unitary mount (ground, bench, truck bed, or hitch), reducing rest displacement during firing. Optional sensors measure trigger and recoil dynamics for testing and QA/QC.
