Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reticles for sniper and hunting rifles, such as those with mil-dot patterns, are difficult to use accurately due to their curved shapes and limited measuring points, which hinder effective trajectory compensation for bullet drop and drift.
Innovation Solution
A reticle design featuring a vertical and horizontal line intersecting at a center point, with a plurality of quadrilaterals that provide multiple measuring points spaced at predetermined distances, allowing for accurate vertical and horizontal trajectory compensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a reticle uses curved shapes like circles or dots for measuring points, then the reticle design is simple and easy to manufacture, but the measuring accuracy and ease of use deteriorate due to limited effective measuring points and difficulty in precise alignment
Solution Approach 1:
The patent divides the reticle into multiple functional components: a mil-dot reticle portion with curved dots for distance estimation, and a quadrilateral reticle portion with straight lines forming multiple measuring points for precise trajectory adjustment. This segmentation allows each portion to serve its optimal function while maintaining overall reticle simplicity.
Solution Approach 2:
The patent transitions from a traditional single-plane reticle design to a multi-planar design where the mil-dot portion and quadrilateral portion operate in different functional planes. The mil-dot dots provide radial distance measurements while the quadrilateral lines provide orthogonal horizontal and vertical measurements, adding a dimensional aspect to the measuring capability.
2Device complexity
If a reticle uses only two measuring points as in traditional mil-dot designs, then the reticle structure remains simple, but the ability to compensate for bullet drop and drift deteriorates due to insufficient measuring points
Solution Approach 1:
The patent merges two distinct reticle designs into a single integrated reticle structure. The mil-dot reticle portion (with its curved dots and radial lines) is combined with a quadrilateral reticle portion (with its straight lines and multiple measuring points), allowing the user to leverage both distance estimation capabilities and precise trajectory adjustment capabilities within one reticle.
Solution Approach 2:
The integrated reticle design provides multiple functions: the mil-dot portion enables distance estimation and radial trajectory adjustments, while the quadrilateral portion enables precise horizontal and vertical trajectory adjustments. This multi-functionality allows a single reticle to handle various shooting scenarios including long-range bullet drop compensation and crosswind drift correction.
3Device complexity
If a reticle uses symmetrical circular measuring points, then the design is simple and aesthetically pleasing, but the ease of operation deteriorates because only one distance measurement is available in all directions
Solution Approach 1:
The patent introduces asymmetry by incorporating a quadrilateral structure with unequal sides and angles, creating measuring points at different distances from the center in different directions. This asymmetric design provides varied measurement intervals for horizontal and vertical adjustments, allowing optimized compensation for different ballistic factors such as bullet drop (vertical) and wind drift (horizontal).

AI summary
A reticle has a vertical line; a horizontal line intersecting the vertical line at a center point; and a plurality of quadrilaterals. Each of the plurality of quadrilaterals intersects either the vertical line or the horizontal line to form first and second measuring points. Each of the first and second measuring points is spaced a predetermined distance from the center point.
