Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Parallax issues in gun sights, particularly in red dot reflex sights like the M68, cause difficulties in achieving accurate zeroing and precise targeting at close distances, leading to wasted training time, excessive ammunition use, and reduced soldier effectiveness and safety.

Innovation Solution

A parallax mitigation device with a cylindrical housing and a reticle system of equal length bars and a connecting member to indicate the center position, or a transparent support surface with crosshairs, is integrated into the reflex sight to assist shooters in precisely centering the red dot, eliminating parallax errors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If multiple lenses are used in the scope to improve optical performance, then the optical capability is improved, but parallax error increases making precise centering difficult

Engineering Contradiction:

Improveoptical performanceVSAvoidcentering precision

Core Design Contradiction:

Illumination intensityVSMeasurement precision

Solution Approach 1:

A parallax mitigation device is introduced as an intermediary component between the scope and the shooter's eye. This device includes a reticle with crosshairs that serves as a reference marker, allowing the shooter to accurately center the red dot on the target without being affected by parallax errors caused by multiple lenses in the scope.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If visual estimation is used for centering the red dot, then the operation is simple, but the accuracy and repeatability of zeroing deteriorates

Engineering Contradiction:

Improvecentering operationVSAvoidzeroing accuracy

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The parallax mitigation device provides self-service by automatically providing a reference reticle with crosshairs that indicates the exact center position. This eliminates the need for the shooter to perform visual estimation of centering, as the reticle objectively defines the center point for accurate zeroing.

Inventive Principle:

Principle #25Self-service

3Loss of time

If parallax errors are present during zeroing, then the weapon can be zeroed quickly, but the accuracy of fire on targets deteriorates

Engineering Contradiction:

Improvezeroing timeVSAvoidfire accuracy

Core Design Contradiction:

Loss of timeVSReliability

Solution Approach 1:

The parallax mitigation device is installed on the scope before zeroing operations begin. This preliminary action ensures that the reference reticle is already in place to guide accurate centering of the red dot, preventing parallax errors from affecting zeroing accuracy while maintaining efficient zeroing procedures.

Inventive Principle:

Principle #10Preliminary action

AI summary

A device for mitigating parallax in a reflex sight. The reflex sight having a front portion for receiving light and a rear portion for providing a visual of a target to a user. The parallax mitigation device defines a reticle positioned in an optical path of the reflex sight. The reticle is configured to indicate a center of the visual provided to the user.
