Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Designating or tagging a target with a precision guided firearm is difficult due to human jitter, especially when telescopic devices magnify this movement, making it challenging to accurately aim and fire.

Innovation Solution

A rifle scope with an image sensor and controller that applies stabilization parameters to both the visual data and reticle, reducing the effect of user movement and jitter, allowing for accurate target selection and tagging.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If telescopic devices are used to magnify the view area, then target designation precision is improved, but human jitter is magnified making target selection more difficult

Engineering Contradiction:

Improvetarget designation precisionVSAvoidtarget selection difficulty

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The display is divided into multiple independently controllable regions: a stabilized view area that remains fixed during jitter and a movable reticle that follows user input. This segmentation allows the magnified view to provide precision while the stabilized background eliminates jitter interference during target selection

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A stabilized image buffer acts as an intermediary between the live camera feed and the display. The buffer captures a reference frame and maintains it stationary while allowing the reticle to move independently, mediating between the magnified view and the user's aiming action to eliminate jitter effects

Inventive Principle:

Principle #24Intermediary (Mediator)

2Stability of the object's composition

If stabilization is applied to the entire view area, then jitter is reduced, but reticle movement relative to the view area becomes difficult to control

Engineering Contradiction:

Improveview stabilityVSAvoidreticle control

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the display have different stability properties: the view area is stabilized to eliminate jitter, while the reticle maintains full mobility to respond to user input. This local differentiation of stability quality allows both view stability and reticle control to coexist

Inventive Principle:

Principle #3Local quality

AI summary

A rifle scope includes an image sensor configured to capture visual data corresponding to a view area, a display, and a controller coupled to the display and the image sensor. The controller is configured to apply a first stabilization parameter to at least a portion of the visual data to produce a stabilized view, to provide the stabilized view and a reticle to the display, and to apply a second stabilization parameter to stabilize the reticle relative to the stabilized view in response to motion.
