Self-Resetting Trigger Simulation Device for Dry Fire Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dry fire training devices for weapons like AR15, AR10, M4, and M16 require manual resetting of the trigger and hammer, which is inconsistent with live ammunition fire and lacks realism.
Innovation Solution
A self-resetting trigger simulation device with a biasing mechanism, such as a tension spring, that automatically returns the trigger lever to a firing position, mimicking the feel of a cocked trigger, allowing for realistic dry fire training.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a manual reset mechanism is used in dry fire training devices, then the device structure is simple, but the training realism is poor because it does not simulate live ammunition fire
Solution Approach 1:
The trigger assembly is designed to automatically reset itself through the integrated biasing mechanism. When the trigger is pulled, the biasing mechanism stores energy and automatically returns the trigger to its original position, eliminating the need for manual resetting by the user. This self-service feature mimics the automatic cycling of live ammunition fire, significantly improving training realism.
Solution Approach 2:
The patent combines the trigger assembly with a biasing mechanism into a single integrated unit that replaces the entire original trigger assembly. This merging of components creates a compact self-resetting system that maintains simplicity while achieving realistic training simulation. The combined structure eliminates separate manual reset operations.
2Productivity
If manual action cycling is required for each trigger pull, then the device requires fewer components, but the training efficiency is reduced due to inconsistent practice with live fire
Solution Approach 1:
The automatic resetting function allows users to continuously pull the trigger without manually cycling the action between shots. This self-service automatic reset maintains consistent practice rhythm and matches the semi-automatic or automatic cycling of live ammunition weapons, significantly improving training efficiency and operation consistency.
3Ease of manufacture
If the trigger assembly is replaced with a simple manual reset device, then the manufacturing cost is low, but the user experience is poor due to lack of realistic trigger feel
Solution Approach 1:
By merging the trigger assembly with a biasing mechanism into one integrated replaceable unit, the patent achieves realistic trigger feel with consistent resistance and automatic reset. This combined design maintains ease of manufacture through modular replacement of a single assembly while delivering authentic trigger pull experience that mimics live fire weapons.

Data Source
AI summary
A device is disclosed that is used temporarily to replace a trigger assembly of a weapon. In one embodiment, the device is self-resetting, including a biasing mechanism to reset a trigger lever to a firing position. As such, the feel of depressing a cocked trigger with each simulated trigger pull is simulated. This device allows the user to experience a more realistic dry fire training session, allowing the user to still cycle the gun action normally if they choose.
