Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current riflescopes with multiple zero points have limited elevation resolution and visibility of indicators, and are not easily adaptable to various ammunition and atmospheric conditions, leading to inaccuracies in long-range shooting.
Innovation Solution
A riflescope aiming system with a multiple-zero-point elevation turret and a ballistics reference system that allows for easy setup and adjustment of indicator markers based on user-inputted parameters, using a calculation tool to determine elevation and wind hold settings, and a card-based system for quick reference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a riflescope uses a turret with multiple indicators for various distances, then the shooter can select an index indicator corresponding to target distance to adjust elevation, but the number of indexing elements is limited by their thickness with respect to the height of the coupler, restricting the number of zero points available
Solution Approach 1:
The patent implements nesting by placing multiple indexing elements (first, second, and third indexing elements) within the turret structure at different radial positions. The indexing elements are arranged concentrically, allowing more zero points to be incorporated without increasing the overall turret height proportionally. This nested arrangement enables the shooter to access multiple distance indicators (e.g., 100, 200, 300, 400, 500 yards) within a compact vertical envelope.
2Measurement precision
If the number of zero stops is increased to improve elevation resolution, then more distances can be calibrated, but the turret rotational range is limited, restricting the total elevation change available
Solution Approach 1:
The patent resolves the rotational range limitation by transitioning from a single-dimensional linear scale to a multi-dimensional angular arrangement. Indexing elements are positioned at different angular positions around the turret circumference, allowing the shooter to access a broader range of elevation values without requiring excessive rotational travel. The multiple indexing elements distributed around the turret provide both fine resolution (through multiple stops) and broad range (through angular distribution).
3Adaptability or versatility
If indicator markers are made smaller to fit more indicators on the turret, then more zero points can be provided, but the visibility and perceptibility of the indicators deteriorates
Solution Approach 1:
The patent applies local quality by varying the size, color, or visual characteristics of different indexing elements based on their specific function or distance range. For example, closer distance indicators might use one visual style while longer distance indicators use another, allowing each indicator to be optimally sized and styled for its specific purpose. This differentiated approach maintains visibility and perceptibility while accommodating multiple indicators on the turret.
4Device complexity
If a single elevation zero point is used to simplify the riflescope design, then the structure remains simple, but it is impossible to accurately and swiftly predict bullet impact at middle to long distances without additional rapid adjustment aids
Solution Approach 1:
The patent implements preliminary action by pre-calculating and pre-marking multiple zero points on the turret for common shooting distances (100, 200, 300, 400, 500 yards). These pre-established indicators allow the shooter to quickly select the appropriate elevation setting for the target distance without performing calculations or making multiple adjustments during the shooting process. The turret is prepared in advance with all necessary elevation references, enabling rapid and accurate target acquisition.

AI summary
A riflescope aiming system that includes a telescopic sight, a multiple-zero-point elevation turret and a ballistics reference system. The multiple-zero-point elevation turret includes a rotatable indicator carrier and a plurality of indicator pins secured to the indicator carrier, each indicator pin corresponding to a predetermined target distance. The ballistics reference system is operably coupled to the objective housing of the telescopic sight and displays ballistics data indicia.
