Multi-function Turret Knob for Rifle Scope Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Military and tactical operations require precise sight adjustments without distracting the shooter from their target, and existing rifle scopes often necessitate using the shooting hand to make adjustments, which can compromise focus and accuracy.
Innovation Solution
A multi-function turret knob with a slip/engagement mechanism and sensors allows for independent adjustment of windage, elevation, and parallax settings using the non-shooting hand, featuring a dual-purpose slip/engagement ring and internal sensors to display adjustment positions directly within the rifle scope, minimizing hand movement and maintaining focus on the target.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the shooter uses the shooting hand to make sight adjustments, then the adjustments can be made, but the shooter's focus on the target is compromised and accuracy decreases
Solution Approach 1:
The non-shooting hand is given the universal capability to perform multiple adjustment functions (windage, elevation, and parallax) through a single integrated turret knob, eliminating the need to use the shooting hand for adjustments while maintaining full sight adjustment functionality
2Adaptability or versatility
If multiple separate adjustment knobs are provided for windage, elevation, and parallax, then all adjustment functions are available, but the device complexity increases and operation becomes less efficient
Solution Approach 1:
Three separate adjustment functions (windage, elevation, and parallax) are merged into a single turret knob assembly, reducing the number of components from three separate knobs to one integrated unit while preserving all adjustment capabilities through a slip/engagement mechanism that selectively activates different adjustment functions
Solution Approach 2:
The turret knob is designed as a multi-functional device that can perform windage adjustment, elevation adjustment, and parallax adjustment through different engagement modes of the slip ring, eliminating the need for multiple separate knobs and reducing overall device complexity
3Ease of operation
If the shooter must move their hand to make sight adjustments, then adjustments can be made, but the shooter breaks focus from the target
Solution Approach 1:
The non-shooting hand is empowered to perform all sight adjustment functions independently, allowing the shooter to make adjustments without any hand movement toward the scope that would break focus, as the entire adjustment mechanism is accessible from the non-shooting hand position

AI summary
A turret knob comprises first and second adjustment members that are both adjustably positionable about an axis of rotation, and a slip/engagement member positioned between the first and the second adjustment members along the axis of rotation. The slip-engagement member is movable between three positions along the axis of rotation. In a first position, the slip-engagement member does not engage the first or the second adjustment members. In the second position, the slip/engagement member engages the first adjustment member to rotatably adjust only the first adjustable member about the axis of rotation as the slip/engagement member is rotated about the axis of rotation. In the third position, the slip/engagement member engages the second adjustable member to rotatably adjust only the second adjustable member about the axis of rotation.
