Firearm Laser Sight with Angled Peripheral Beams for Spread Pattern
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Firearm sighting systems fail to effectively represent the spread pattern of projectiles at varying distances, particularly for firearms that fire multiple projectiles simultaneously, such as shotguns, where the impact area increases with distance, leading to inaccuracies in target acquisition.
Innovation Solution
A laser sighting system with a housing configured to mount on a firearm, featuring a plurality of peripheral lasers positioned at specific angles to project a pyramidal or conical pattern of light beams, which increases in size with distance, along with a central target laser and optional LED lights for illumination and adjustment capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single laser or simple sight system is used, then the device complexity is low, but the ability to represent projectile spread pattern at varying distances is insufficient
Solution Approach 1:
The system divides the laser sighting function into multiple independent laser units (typically five lasers: one central and four peripheral). Each laser projects an individual beam, and collectively they form a comprehensive spread pattern representation. This segmentation allows accurate depiction of projectile dispersion without requiring a single complex laser system.
Solution Approach 2:
The patent combines multiple laser beams into a unified visual pattern that represents the complete projectile spread area. The central laser indicates the aim point while peripheral lasers define the spread boundaries, merging individual beam functions into a comprehensive targeting system that accurately represents ballistic dispersion.
2Measurement precision
If parallel lasers are used as in prior art, then the device structure is simple, but the projected pattern does not increase in area with distance to represent spread pattern
Solution Approach 1:
The peripheral lasers are angled relative to the central laser axis, introducing a dimensional component that causes the light pattern to expand radially with distance. This angular arrangement transforms the simple parallel beam pattern into a conical or pyramidal spread pattern that accurately represents how projectiles disperse over distance, adding the dimension of angular divergence to the optical geometry.
3Measurement precision
If multiple peripheral lasers are positioned at angles to create an expanding pattern, then the spread pattern representation improves, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The system uses specific angular parameters for laser positioning (typically 45 degrees for peripheral lasers relative to the central axis) that create the desired expanding pattern while simplifying manufacturing. By standardizing these angular parameters, the system achieves accurate spread pattern representation without requiring complex custom mounting solutions, making the angled configuration manufacturable with standard precision tolerances.
