Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current military sniper systems require snipers to manually adjust rifle scopes, which can lead to loss of focus and noise, compromising accuracy and stealth due to the need for verbal communication and manual adjustments for aiming and windage calculations.

Innovation Solution

A rifle scope display adapter that projects aiming information, such as a targeting reticle, onto the scope's field of view, allowing snipers to align the reticle with the target without removing their eyes or adjusting the scope, using a ballistic computer for precise calculations and wireless communication with a spotter.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual scope adjustment is used, then aiming information can be obtained, but sniper accuracy and stealth are compromised due to loss of focus and noise

Engineering Contradiction:

Improveaiming accuracyVSAvoidnoise and loss of focus

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent replaces manual mechanical scope adjustment with an automated electronic display system. The rifle scope display adapter projects aiming information including reticles and adjustment indicators onto the scope's field of view, allowing the sniper to make precise aiming adjustments by simply moving the rifle without manually adjusting scope turrets or knobs. This eliminates the mechanical adjustment process that causes loss of focus and generates noise.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The display adapter serves as an intermediary device between the sniper and the target. It processes aiming information from ballistic computers and presents it visually through the scope's field of view, mediating the complex task of manual adjustment and reducing it to simple rifle movement while maintaining precision.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If verbal communication is used for target information, then coordination between spotter and sniper is achieved, but stealth is compromised due to noise

Engineering Contradiction:

Improvecoordination between spotter and sniperVSAvoidnoise

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent replaces verbal communication with wireless electronic communication. The display adapter receives aiming information wirelessly from ballistic computers carried by the spotter, transmitting data without sound through radio frequency or other wireless protocols, thereby maintaining coordination while eliminating noise that would compromise stealth.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Measurement precision

If manual scope adjustment is used, then windage and elevation calculations can be applied, but productivity is reduced due to time loss

Engineering Contradiction:

Improvefiring solution accuracyVSAvoidtime to acquire target

Core Design Contradiction:

Measurement precisionVSProductivity

Solution Approach 1:

The system performs preliminary calculations of windage and elevation adjustments through ballistic computers before the sniper needs to aim. The display adapter then presents the pre-calculated firing solution as a visual reticle overlay, allowing the sniper to immediately align with the target without performing manual calculations or sequential adjustments, significantly reducing time to acquire target while maintaining precision.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent replaces the time-consuming manual process of calculating and adjusting windage and elevation with automated electronic computation and visual display. The ballistic computer rapidly calculates firing solutions and the display adapter presents them instantly as visual guidance, eliminating the sequential manual adjustment process.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

This disclosure describes a compact and lightweight rifle scope display adapter configured to be affixed in front of the objective lens of a rifle scope. The display adapter includes a receptacle that enables the adapter to be electrically connected to a ballistic computer, rangefinder or other targeting mechanism. The display adapter is configured to receive aimpoint information and project illuminated symbology that is brought into focus by the rifle scope optics in such a way that the symbology appears to overlay an image of a scene on which the rifle scope is focused. The display adapter includes a casing that houses processing circuitry, a light emitting diode, polarizer, polarized beam splitter, liquid crystal on silicon imaging element and reflective element. The display adapter also includes a light bar, spherical mirror, quarter-wave plate and an additional polarized beam splitter contained within the light bar.
