Marksman Positioning Device for Optical Sight Parallax Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inconsistent marksman eye positioning with optical sights leads to parallax error, affecting the accuracy of firearm projectile placement, especially in long-distance shooting, as existing devices fail to effectively reduce parallax while maintaining minimal obstruction and easy use.
Innovation Solution
A marksman positioning device with an alignment pattern integrated into or applied to the ocular lens of optical sights, allowing consistent eye placement by correlating with the reticle, visible only in the central region of the target picture, and secured using suction or a flexible frame to minimize disruption and facilitate easy installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an alignment device is added to reduce parallax error, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The alignment pattern is merged with the ocular lens or reticle assembly, combining the parallax reduction function with the existing optical components. This integration eliminates the need for separate alignment devices while maintaining the ability to provide parallax error reduction.
Solution Approach 2:
The alignment pattern acts as an intermediary visual reference between the marksman's eye and the reticle. By providing this intermediate alignment feature, the system enables precise eye positioning without requiring complex mechanical adjustment mechanisms.
2Ease of operation
If an alignment pattern is made visible in the target picture, then ease of operation is improved, but loss of information increases
Solution Approach 1:
The alignment pattern is positioned in a specific local region of the optical system (ocular lens or reticle area) rather than throughout the entire field of view. This localized placement provides alignment functionality while preserving the clarity and information content of the main target picture.
Solution Approach 2:
The alignment pattern occupies only a partial portion of the visual field, sufficient to provide alignment reference but limited enough to minimize interference with target acquisition and picture clarity.

AI summary
Device and related methods for improving the accuracy and precision of firearms fitted with optical sights. The device comprises a small alignment pattern for indexing against a small, central region of a target picture aimpoint or reticle. The alignment pattern is applied to an auxiliary lens fixed in position externally behind an ocular lens. The auxiliary lens is supported by a frame secured to the optical sight or the auxiliary lens is made to adhere to the outside surface of the ocular lens. Some embodiments refract or condition light to improve target pictures. Alternatively, an alignment pattern, without an auxiliary lens, is applied directly to or made integral with an ocular lens during the manufacture of an optical sight. In general, referencing the alignment pattern with the reticle, by adjusting eye placement until a desired alignment is observed, provides consistent shooter positioning and reduced parallax.
