Rifle Scope Turret Spiral Cam With Zero And Maximum Stops
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rifle scope turrets lack adjustment stops, rotation indicators, and locking mechanisms, making it difficult to accurately adjust for bullet drop and wind drift, especially in poor lighting conditions, and are prone to inadvertent adjustments.
Innovation Solution
The rifle scope incorporates a spiral cam mechanism with adjustment stops, a rotation indicator, and a locking mechanism to prevent over-adjustment and provide tactile feedback, ensuring precise elevation and windage adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional turrets allow multiple rotations for long-range compensation, then the scope can compensate for longer-range targets and environmental conditions, but the user may lose track of how many rotations are dialed in and turrets can be easily bumped
Solution Approach 1:
The patent implements a rotation indicator that provides visual feedback to the user about the number of rotations dialed in. This feedback mechanism allows users to track their adjustments without having to count manually, preventing loss of track while maintaining the ability to make multiple rotations for long-range compensation.
Solution Approach 2:
The turret is divided into rotational segments with markings that indicate the number of rotations. The rotation indicator is segmented to show discrete rotation counts, breaking down the continuous rotation into manageable, trackable segments that reduce the likelihood of user error.
2Device complexity
If conventional turrets omit adjustment stops and locking mechanisms, then the turret structure remains simple, but users cannot prevent over-adjustment and turrets are prone to inadvertent adjustments
Solution Approach 1:
The patent incorporates adjustment stops that are preset to prevent the turret from being adjusted beyond safe limits. These stops provide preliminary protection against over-adjustment by physically blocking further rotation before user error can occur, maintaining reliability without requiring complex locking mechanisms.
Solution Approach 2:
The adjustment stops act as intermediary elements between the turret rotation and the optical elements. These stops mediate the adjustment process by limiting the range of motion to safe levels, preventing direct contact between excessive rotation and the optical components.
3Volume of moving object
If markings on conventional turrets are small for compact scope components, then the scope remains compact, but markings are difficult to read under poor lighting conditions
Solution Approach 1:
The patent employs high-contrast markings with distinct visual characteristics that enhance visibility under poor lighting conditions. The rotation indicator uses markings that stand out clearly against the background, making them detectable even in low-light environments while maintaining compact scope dimensions.
Solution Approach 2:
The rotation indicator extends the information display into a third dimension by projecting rotation counts outward from the turret. This dimensional extension allows users to read rotation information from a distance without increasing the footprint of the markings on the turret surface itself.

AI summary
Rifle scope turrets with spiral cam mechanisms include a scope body, a movable optical element defining an optical axis enclosed by the scope body, and a turret having a screw operably connected to the optical element for adjusting the optical axis in response to rotation of the screw. The turret has a spiral cam mechanism engaged thereto. The turret defines first and second stop surfaces positioned for engagement by the spiral cam to limit rotation of the turn The first stop surface defines a zero position of the screw and the movable optical element. The second stop surface defines a maximum point of displacement of the screw and the moveable optical element. The stop surfaces may be defined by a spiral cam groove in the indexing portion of the turret. The groove may overlap itself at least partially. The turret may be an elevation turret or a windage turret.
