Telescopic Gunsight Reticle System for Ballistic Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional telescopic target acquisition devices are inadequate for achieving accuracy at long ranges due to limitations in compensating for bullet drop and windage effects, and they often require adjustments that divert the shooter's attention from the target, while laser rangefinders pose risks of detection and are cumbersome.
Innovation Solution
A reticle system integrated into telescopic gunsights that includes an optical rangefinder, allowing shooters to quickly and accurately estimate range and make adjustments for bullet drop and windage without moving adjustment rings, using a reticle with proportional markings that remain consistent across magnification levels, enabling precise targeting at various ranges without diverting attention from the target.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional telescopic target acquisition devices are used with standard cross-hairs, then the device structure remains simple, but the device cannot provide accurate targeting at long ranges due to inability to compensate for bullet drop and windage effects
Solution Approach 1:
The reticle is divided into multiple distinct aiming points arranged in a grid pattern, with each point calibrated for specific ranges and compensation values. This segmentation allows the shooter to select the appropriate aiming point for the target distance without requiring complex mechanical adjustments, thereby improving measurement precision while maintaining relatively simple device structure.
Solution Approach 2:
The patent transitions from a single-plane cross-hair system to a multi-level reticle system with aiming points distributed across different positions and depths in the field of view. This dimensional expansion enables simultaneous presentation of multiple range solutions without adding mechanical complexity, resolving the contradiction between accuracy and simplicity.
2Measurement precision
If adjustment rings are used to compensate for bullet drop and windage, then targeting accuracy can be improved, but the shooter's attention is diverted from the target during adjustments
Solution Approach 1:
Multiple aiming points are pre-calculated and pre-positioned on the reticle for various ranges and wind conditions. The shooter can directly select the appropriate pre-prepared aiming point based on estimated range, eliminating the need for time-consuming adjustments during the shooting sequence. This preserves both accuracy and rapid target acquisition.
Solution Approach 2:
The reticle system provides self-service by embedding all necessary compensation data directly in the aiming points. The shooter uses the system without needing to perform separate calculation or adjustment operations, allowing continuous focus on the target while the reticle automatically provides the correct aiming solution for the given conditions.
3Measurement precision
If laser rangefinders are used to determine target distance, then range measurement precision is improved, but the device becomes cumbersome and poses detection risks
Solution Approach 1:
The patent extracts the rangefinding function from external electronic devices and integrates it into the optical reticle system itself through geometric scaling relationships. By using the known size of standard targets and the angular size measured through the scope, the system calculates range purely through optical geometry, eliminating the need for laser rangefinders and their associated complexity and detection risks.
Solution Approach 2:
The patent replaces electronic laser rangefinding systems with an optical-geometric calculation method embedded in the reticle. This substitution eliminates electronic components and power requirements, reducing device complexity while maintaining range measurement precision through pure optical means.
4Adaptability or versatility
If reticle markings are made proportional to magnification, then the reticle remains useful across variable power settings, but the manufacturing precision requirements increase
Solution Approach 1:
The reticle is designed with universal aiming points that function correctly across multiple magnification levels. The grid pattern and spacing are calculated to maintain proportional relationships that work at any power setting, allowing a single reticle to serve multiple functions and ranges without requiring multiple specialized reticles or complex adjustment mechanisms.
