Solution Overview
Problem
Conventional riflescopes require users to remove their eye from the view to interpret turret knob markings, making it inconvenient to determine the rotational position of adjustment assemblies for compensating bullet trajectory factors in long-range shooting.
Innovation Solution
An adjustment assembly for riflescopes incorporating a knob, a disc with a varying trace, sensors, and a processor to measure and correlate the trace characteristics with rotational displacement, allowing for precise determination of the erector tube displacement without needing to remove the eye from the view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional turret knob markings are used for adjustment, then the device complexity is reduced, but the ease of operation deteriorates because users must remove their eye from the view to interpret markings
Solution Approach 1:
The patent replaces the mechanical interpretation of turret knob markings with an optical system. A camera captures images of the turret knob, and image processing algorithms automatically determine the rotational position and adjust the reticle position accordingly. This substitution eliminates the need for users to visually interpret markings and manually calculate adjustments, thereby improving ease of operation while accepting increased device complexity through the addition of camera and processing components.
2Productivity
If visual interpretation of turret markings is required, then the device complexity is minimized, but the loss of time increases due to repeated eye removal and interpretation
Solution Approach 1:
The system performs self-service by automatically capturing images of the turret knob, processing the images to determine rotational position, and calculating the required reticle adjustment without user intervention. The camera continuously monitors the turret position, and the processor automatically correlates the position with the appropriate reticle coordinates, eliminating the need for users to repeatedly remove their eyes to check markings and manually adjust settings.
3Ease of operation
If automated sensors and processors are added to eliminate visual interruption, then the ease of operation improves, but the device complexity increases
Solution Approach 1:
The patent introduces a camera as an intermediary between the turret knob and the user. Instead of the user directly observing and interpreting markings, the camera captures the turret position and transfers this information to the processing system, which then determines the reticle adjustment. This intermediary eliminates the need for direct visual interpretation by the user, improving ease of operation while managing the complexity through a standardized imaging interface.

AI summary
An adjustment assembly for riflescopes and related methods are provided. In one example, an adjustment assembly includes a knob configured to rotate about an axis, a disc having a trace, a first sensor configured to measure a value relating to a particular portion of the trace, and a second sensor configured to sense complete revolutions of the knob about the axis. The riflescope also includes a processor configured to correlate the value with an angular displacement of the knob about the axis relative to a zero point.
