Solution Overview

Problem

Current rifle scope systems require snipers to manually adjust the scope while removing their hands and eyes from the target, which can lead to inaccuracies and noise that compromise the shooting position, as they rely on verbal communication for aiming information from a spotter.

Innovation Solution

A rifle scope display adapter that securely mounts to the front of the scope, providing illuminated aim point and trajectory information through optical components, allowing the sniper to maintain their position and focus on the target without manual adjustments, using liquid crystal on silicon (LCOS) reflective elements and light emitting circuitry to overlay symbology onto the target view.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual scope adjustment is used, then aiming information can be changed, but the sniper must remove hands and eyes from the target position

Engineering Contradiction:
Improvescope adjustment operationVSAvoidshooting position stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent replaces manual mechanical scope adjustment with an electronic display system that shows aiming information on a screen mounted on the scope. The sniper can change aim points by touching the screen interface without moving the scope mechanically, thus maintaining shooting position stability while achieving ease of operation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a display screen as an intermediary between the sniper and the scope adjustment mechanism. The screen presents aiming information and allows selection of new aim points without requiring direct manual manipulation of the scope's mechanical adjustment knobs, eliminating the need to remove hands from the trigger position.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If manual scope adjustment is used, then aiming information can be changed, but verbal communication between spotter and sniper generates noise

Engineering Contradiction:
Improveaiming information transmissionVSAvoidnoise from verbal communication
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The patent replaces verbal acoustic communication with a visual electronic display system. The spotter's aiming information is transmitted electronically to the scope's display screen, allowing the sniper to receive and act on aiming data without any verbal exchange, thus eliminating noise generation while maintaining ease of information transmission.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If manual scope adjustment is used, then the scope can be repositioned, but the rifle may shift on the support

Engineering Contradiction:
Improvescope positioning flexibilityVSAvoidrifle position stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent substitutes mechanical scope repositioning with electronic aim point selection displayed on the screen. The sniper can select different aim points by interacting with the display interface without physically moving the scope or rifle, thereby maintaining adaptability in target selection while ensuring rifle position stability on the support.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Ease of operation

If the sniper takes eyes off the target for manual adjustments, then scope can be repositioned, but targeting accuracy may be reduced

Engineering Contradiction:
Improvescope adjustment capabilityVSAvoidtargeting accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent replaces the need to physically move the scope with an electronic display interface that shows multiple aim points. The sniper can select new aim points by touching the screen while keeping eyes on the target through the scope, maintaining targeting accuracy while achieving scope repositioning capability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enables accurate targeting without manual scope adjustments, maintaining the sniper's position and reducing noise, by projecting aim point indicators directly onto the target view through the rifle scope, allowing for precise compensation of windage and bullet drop without disturbing the shooting posture.

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 adapter includes a mounting assembly that provides two attachment mechanisms. A first ring of the RDA can be screwed into the threads on the interior surface of the scope. Additionally, the scope can be inserted into a second ring of the RDA and provides compressive, radial pressure against the outside surface of the scope.
