Multi-Axis Trigger Displacement Monitoring System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional firearm systems fail to accurately monitor and provide feedback on the trigger pull path, leading to inaccuracies due to lateral and vertical displacement during trigger activation, which affects the firearm barrel's alignment and shot accuracy.
Innovation Solution
A firearm system equipped with a multi-axis position controller and microcontroller that senses and graphically displays the trigger displacement along longitudinal, lateral, and vertical axes, allowing users to improve their trigger pull technique and barrel alignment through real-time feedback on an electronic device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional firearm systems are used without multi-axis monitoring, then the device complexity is low, but the measurement precision of trigger pull path is insufficient
Solution Approach 1:
The trigger pull monitoring function is segmented into three independent single-axis position controllers, each measuring displacement along one axis (longitudinal, lateral, vertical). This modular segmentation allows precise multi-axis measurement while keeping each controller's design simple and manageable, resolving the contradiction between measurement precision and device complexity.
Solution Approach 2:
A microcontroller serves as an intermediary that receives data from all three single-axis position controllers, processes the combined information, and generates the composite trigger pull path indication. This intermediary approach enables integrated multi-axis monitoring without requiring a complex monolithic controller, thus improving measurement precision while controlling system complexity.
2Measurement precision
If single-axis position controllers are used for each axis, then the measurement precision of trigger displacement is improved, but the device complexity increases
Solution Approach 1:
The monitoring system is divided into three separate single-axis position controllers, each dedicated to measuring displacement along one specific axis. This segmentation allows each controller to be optimized for its specific measurement task, improving measurement precision while maintaining simplicity at the component level. The complexity is distributed rather than concentrated.
Solution Approach 2:
The outputs from the three separate single-axis position controllers are merged and processed by a single microcontroller that generates a unified trigger pull path indication. This merging approach allows the system to achieve comprehensive multi-axis monitoring capability while using relatively simple individual components, balancing measurement precision with overall system complexity.

AI summary
A firearm system for monitoring the displacement of a firearm trigger during a trigger pull includes a firearm body including a handle and a barrel attached to the handle. A trigger is attached to the firearm body, and a position input circuit is attached to the trigger. The position input circuit emits a trigger position signal including information representative of the trigger displacement. The firearm body is in wired or wireless communication with an electronic device. The electronic device can include a monitor, or screen, for graphically displaying a trigger position indicator representative of the displacement of the trigger along one or more axes. The firearm body can include a motion sensing circuit generally adapted to detect motion of the firearm body. The motion sensing circuit can include one or more accelerometers or gyroscopes. A wireless transmitter or transceiver can be positioned on the firearm body for communicating trigger displacement information and/or firearm body motion information to the electronic device. Methods of providing firearm user input information to a firearm user are also provided.
