Adjusting Turret Torque Segmentation for Optical Sights
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjusting turrets for long-range optical devices, such as telescopic sights, are prone to unintentional rotation due to accidental contact or knocks, leading to unwanted adjustments, and existing solutions require complex manipulation sequences to prevent this.
Innovation Solution
Incorporating a rotatable rotation stop on the rotary cap that requires a smaller torque than the actuating torque, which can rotate independently of the spindle, along with a separate scale and potentially multiple rings with markings, to absorb unintended torque and prevent unwanted adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking mechanism is added to prevent unintentional rotation of the rotary cap, then reliability is improved, but device complexity increases
Solution Approach 1:
The rotary cap is segmented into two independent rotational components: the main rotary cap for adjustment and a separate rotation stop for protection. The rotation stop can rotate independently on the exposed surface while the main adjustment mechanism remains locked, providing protection without requiring complex locking systems.
Solution Approach 2:
The rotation stop acts as an intermediary element between the user's hand and the main adjustment mechanism. It absorbs accidental contact and torque, preventing these forces from being transmitted to the spindle and optical system, thus protecting against unintentional rotation without complicating the overall structure.
2Reliability
If the rotary cap is made more secure to prevent rotation, then reliability is improved, but ease of operation deteriorates
Solution Approach 1:
By segmenting the rotary cap into a main body and a separate rotation stop, the invention allows the rotation stop to be freely rotatable for intentional adjustments while preventing unintentional rotation through its protective function. This segmentation maintains ease of operation for the main adjustment mechanism while providing security.
Solution Approach 2:
Different parts of the rotary cap have different rotational properties: the rotation stop on the exposed surface is designed to be freely rotatable to absorb accidental contact, while the main adjustment mechanism requires deliberate torque to rotate. This local differentiation of rotational characteristics provides both protection and ease of operation.

AI summary
An adjusting turret for a telescopic sight or reflex sight includes a rotary cap, which is rotatable about a rotary axis by applying a first torque, as an actuator for a spindle, wherein the rotary cap includes at least one rotation stop which is rotatable relative to the spindle about the rotary axis by applying a second torque that is smaller than the first torque, wherein the adjusting turret has at least one scale which is arranged on a part that is separate from the rotation stop.
