Supplementary Sight Aid Axial Projection for Scope Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional iron sights are difficult to use for precise aiming due to lack of visual feedback for vertical alignment and are not effective when used with scopes, leading to eye-straining and unsatisfactory alignments, and existing aids like laser projections require frequent power replenishment.
Innovation Solution
A sight aid with an illuminated supplementary sight alignment indicator is provided, disposed forward of the objective lens and axially-centered with respect to the primary sight alignment indicator, allowing for precise alignment and reduced power consumption by projecting indicators within the scope's vicinity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If an iron sight is used for aiming through a scope, then the scope provides magnification and extended range, but the iron sight cannot be seen or picked up in the sight pictures, making precise alignment impossible
Solution Approach 1:
The patent introduces a light source as an intermediary element that projects a visible alignment indicator onto the target or into the field of view. This mediator bridges the gap between the invisible iron sight and the user's line of sight, enabling precise alignment to be seen and adjusted while maintaining the magnification capability of the scope.
2Ease of operation
If an iron sight is used without a scope, then rough aiming is possible, but the alignment process is difficult and eye-straining with unsatisfactory results
Solution Approach 1:
The patent implements a visual feedback mechanism where the light source projects an alignment indicator that provides real-time visual information to the user about the alignment status. This feedback loop allows the user to see whether the alignment is correct and make adjustments accordingly, eliminating the eye-straining guesswork associated with traditional iron sights and achieving precise alignment effortlessly.
3Measurement precision
If laser beams are projected onto the target for aiming assistance, then alignment visualization is improved, but a significant amount of power is consumed requiring frequent replenishment
Solution Approach 1:
The patent changes the operational parameters of the light source by using intermittent or pulsed illumination rather than continuous laser projection. This parameter change significantly reduces power consumption while still providing adequate alignment visualization during the brief periods when illumination is active, eliminating the need for frequent power replenishment.
4Device complexity
If the supplementary sight alignment indicator is disposed in close proximity to the primary reticle, then the device complexity is reduced, but the alignment effectiveness is diminished
Solution Approach 1:
The patent positions the supplementary sight alignment indicator at a different axial distance from the primary reticle, utilizing the depth dimension within the optical path. This spatial separation in the axial dimension allows both indicators to be simultaneously visible and functional, with the supplementary indicator providing distinct visual reference points that enhance alignment effectiveness without adding significant device complexity.

AI summary
A sight aid including a supplementary sight alignment indicator having a projection plane and a projection device adapted to project a supplementary sight alignment indicator and at least one reference point on the projection plane, the supplementary sight alignment indicator is axially-centered with respect to the sight alignment indicator and spaced apart therefrom on the optical axis for forming a composite image with the image of the sight alignment indicator, the target image being viewable together by the user by means of the ocular lens and the projection plane is disposed at a distance from the sight alignment indicator. An adaptor secures the supplementary sight alignment indicator to a portion of the projectile device or the housing.
