Rifle Scope Turret Assembly Locking and Zero Stop Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current rifle scope turret assemblies lack mechanisms to securely lock and limit adjustments, leading to potential unintended changes in target settings, and lack indicators for precise position depiction, affecting accuracy in ballistic applications.
Innovation Solution
A turret assembly with a locking mechanism using a movable locking pin to prevent rotational movement, a stopping mechanism with a zero stop ring to limit rotational adjustments, and an indicator for translational movement to depict position changes, ensuring secure and precise adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking mechanism with a movable locking pin is added to prevent rotational movement of the turret cap, then the reliability of maintaining target settings is improved, but the device complexity increases
Solution Approach 1:
The locking mechanism is segmented into distinct functional components: a locking pin that can move between locked and unlocked positions, a locking cavity in the turret body, and engagement features on the turret cap. This segmentation allows each component to perform its specific function independently while contributing to the overall reliability of maintaining target settings without excessive complexity.
Solution Approach 2:
The locking pin is designed to be movable between a locked position (where it engages with the turret cap to prevent rotation) and an unlocked position (where it allows rotation for adjustment). This dynamic capability enables the system to transition between locked and unlocked states, providing reliability when needed while maintaining operational flexibility, thus resolving the contradiction between reliability and device complexity.
2Manufacturing precision
If a stopping mechanism with a zero stop ring is added to limit rotational adjustments, then the manufacturing precision of adjustments is improved, but the device complexity increases
Solution Approach 1:
The zero stop ring is pre-positioned within the turret body to define a zero stop point that limits rotational adjustments in one direction. This preliminary positioning ensures that adjustments cannot exceed predetermined boundaries, improving manufacturing precision by preventing over-adjustment or incorrect positioning, while the simple ring structure adds minimal complexity to the device.
3Measurement precision
If an indicator configured for translational movement is added to depict position changes, then the measurement precision of turret position is improved, but the device complexity increases
Solution Approach 1:
The indicator acts as an intermediary component that translates the rotational position of the turret cap into a visible translational movement. As the turret cap rotates to adjust target settings, the indicator moves translationally to depict the position change, providing precise measurement information without requiring complex sensing or measurement systems, thus improving measurement precision while adding minimal complexity.

AI summary
A turret assembly configured to be coupleable to the combination of a rifle scope and a rifle, to adjust the rifle scope relative to the rifle is provided. The turret assembly includes a turret body, a jacking screw, and a turret cap. The turret assembly may also include a locking mechanism including a locking pin configured to prevent rotational movement of the turret cap relative to the turret body. The turret assembly may include a stopping mechanism configured to limit rotational movement of the turret cap relative to the turret body. The stopping mechanism may include a zero stop ring which defines a zero stop point which prevents further rotational movement of the turret cap. The turret assembly may also include an indicator configured to depict information about the position of the turret cap relative to the turret body, where the indicator is configured for only translational movement.
