Recoil Detection Device for Real-Time Shooting Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing target shooting systems lack real-time feedback, making it difficult for shooters to adjust their aim between shots, as the accuracy of shots and shooter's actions are hard to judge and often delayed.
Innovation Solution
A recoil detection device equipped with an accelerometer, gyroscope, and magnetometer, which provides real-time feedback by tracking the shooter's recoil and connecting wirelessly to a smartphone or computer, allowing for instant analysis of shooting performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a recoil sensor is attached to the firearm or person's body to trigger the monitoring system, then real-time tracking of shooting performance is achieved, but the device becomes large and cumbersome that interferes with the shooter's aim or shooting comfort
Solution Approach 1:
The system divides the monitoring function into separate components: a small sensor unit attached to the shooter's body (fingertip, wrist, or arm) rather than the firearm, and a separate processing/display unit. This segmentation allows the sensor to be minimally invasive while still capturing recoil data for real-time analysis.
Solution Approach 2:
The patent replaces traditional mechanical recoil sensors with a multi-sensor approach using accelerometers, gyroscopes, and magnetometers. These electronic sensors detect recoil through subtle body movements and magnetic field changes, eliminating the need for large mechanical recoil measurement devices attached to the firearm.
2Measurement precision
If acoustic sensors are used to trigger the monitoring system, then shooting accuracy tracking is achieved, but the system becomes overwhelmed by loud gunfire sounds and echoes in multi-person ranges
Solution Approach 1:
The system replaces acoustic sensing with mechanical/biomechanical sensing by attaching sensors directly to the shooter's body. The accelerometers, gyroscopes, and magnetometers detect physical recoil movements and magnetic field changes caused by gunfire, completely eliminating dependence on acoustic signals and their associated interference problems.
Solution Approach 2:
The sensor unit acts as an intermediary between the gunfire event and the monitoring system. Instead of directly detecting sound waves that can be overwhelmed by echoes and multiple shooters, the intermediary sensor unit captures subtle body movements and magnetic changes that uniquely identify each shot event.
3Measurement precision
If a sensor attaches to the firearm to sense motion, then shooting tracking is enabled, but the attachment changes the shooter's aim
Solution Approach 1:
The system separates the sensing function from the firearm by attaching the sensor unit to the shooter's body instead. This segmentation ensures that no additional weight or attachment point is introduced on the firearm that could affect balance or aim, while still enabling comprehensive shooting tracking through body movement detection.

Data Source
AI summary
The recoil detection device detects the recoil associated with a person firing a firearm. The recoil device measures information using motion sensors such as an accelerometer, gyroscope, and magnetometer, and analyzes that information to indicate the firearm has been fired. The information is processed and aggregated to generate useful information to the person shooting the firearm and to anyone on the internet.
