Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical scopes for firearms require complex calculations using mil dots for range estimation, which can be cumbersome and inaccurate, especially under stress, due to the need for memorization and mental calculations.
Innovation Solution
A multi-distance ranging reticle with secondary horizontal crosshairs and vertical markings allows users to quickly estimate range by framing an object of known width between specific markings, simplifying the process and reducing reliance on complex calculations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mil dots are used for range estimation, then ranging functionality is provided, but the device complexity and ease of operation deteriorate due to requiring memorization and complex calculations
Solution Approach 1:
The reticle is segmented into multiple horizontal crosshairs (first, second, third horizontal crosshairs) with different spacing configurations. Each horizontal crosshair provides a distinct ranging scale, allowing users to select the appropriate crosshair for the expected range, thereby simplifying the ranging process while maintaining versatile ranging functionality across multiple distances.
Solution Approach 2:
The patent transitions from a single vertical mil dot scale to a two-dimensional grid system with multiple horizontal crosshairs at different vertical positions. This dimensional expansion allows simultaneous presentation of multiple ranging scales, enabling users to quickly estimate range without complex calculations by simply observing which horizontal crosshair aligns with the target.
2Adaptability or versatility
If mil dots are used for range estimation, then ranging functionality is provided, but productivity deteriorates due to time-consuming calculations under stress
Solution Approach 1:
The reticle pre-configures multiple horizontal crosshairs with spacing that corresponds to standard target distances (e.g., 100 yards, 200 yards, 300 yards). Users perform preliminary ranging by simply observing which pre-configured horizontal crosshair aligns with the target, eliminating the need for real-time calculations and significantly improving aiming efficiency under stress.
Solution Approach 2:
The reticle design enables self-service ranging where the optical device itself provides the ranging information through its built-in multi-distance crosshairs. The user simply needs to observe the alignment between the target and the appropriate horizontal crosshair, with no external calculating devices or complex mental computations required, thereby maintaining high productivity.
3Adaptability or versatility
If multiple horizontal crosshairs are added to provide multi-distance ranging, then adaptability improves, but device complexity increases
Solution Approach 1:
Each horizontal crosshair serves multiple functions: it acts as a ranging scale for a specific distance, provides a reference line for target alignment, and can be used for both close-range and long-range estimation depending on which crosshair aligns with the target. This multi-functionality allows the reticle to provide adaptability for multiple distances without proportionally increasing complexity.
Solution Approach 2:
The reticle design allows dynamic selection of the appropriate horizontal crosshair based on the expected target distance. Users can mentally select which horizontal crosshair to use based on range estimation, making the system adaptable without requiring physical adjustment mechanisms, thereby managing complexity while maintaining versatility.

AI summary
A multi-distance ranging reticle for an optical device is provided. The reticle can include a primary vertical crosshair transverse to a primary horizontal crosshair, a secondary horizontal crosshair having a first vertical marking and a second vertical marking, separated by a distance, the secondary horizontal crosshair corresponding to a first range. A first object having a first known width can be placed between the first and second vertical markings to estimate a first estimated range to the first object. An assortment of other vertical markings can be disposed along the secondary horizontal cross hair, and/or other additional horizontal crosshairs and separated by other distances corresponding to other known widths of other objects. By selectively framing an object of a known width between certain vertical markings along a particular horizontal crosshair, a user can quickly and efficiently estimate range of the object.
