Adjusting Turret With Tunable Click Hardness for Telescopic Sights
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjusting turrets for long-range optical devices, such as telescopic sights, provide a constant rotary resistance perceived as 'click hardness' regardless of user preference or conditions, which can be a disadvantage, especially when using the device with gloves or for users with different preferences.
Innovation Solution
The adjusting turret incorporates an adjusting element for stepless adjustment of rotary resistance, allowing users to individually adjust the force required for rotation by varying the hardness of an elastic element or its pretensioning, enabling customizable 'click hardness' through displacement of the detent element and use of a force-transmitting element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a constant rotary resistance is provided in the adjusting turret, then the mechanical structure is simple and reliable, but the adaptability to different user preferences and conditions deteriorates
Solution Approach 1:
The patent applies the dynamics principle by making the rotary resistance adjustable rather than fixed. The elastic element's pretensioning can be modified to change the click hardness, transforming a static mechanical system into a dynamic one that adapts to different user needs while maintaining mechanical reliability through a simple adjustment mechanism.
Solution Approach 2:
The patent implements parameter changes by allowing modification of the elastic element's pretensioning force. This changes the physical parameter of rotary resistance, enabling the same mechanical structure to provide different click hardness levels for different users or conditions without altering the fundamental mechanical design.
2Adaptability or versatility
If the rotary resistance is made adjustable, then the adaptability to different user preferences is improved, but the device complexity increases
Solution Approach 1:
The adjusting element serves multiple functions: it adjusts the pretensioning of the elastic element, modifies the rotary resistance, and maintains the overall structural integrity. This multi-functionality reduces the need for separate adjustment mechanisms, thereby limiting the increase in device complexity while achieving customizable click hardness.
Solution Approach 2:
The adjusting element is integrated within the existing turret structure, nesting the adjustment function within the overall mechanism. This allows the adjustment capability to be incorporated without adding significant external components, thus minimizing the increase in device complexity.
3Measurement precision
If the detent element is forced out of engagement with high rotary resistance, then the click perception is clear and distinct, but the ease of operation deteriorates especially when wearing gloves
Solution Approach 1:
The patent allows adjustment of the rotary resistance parameter to optimize the balance between click perception clarity and ease of operation. Users can reduce the resistance when wearing gloves or other restrictive items, making operation easier while still maintaining sufficient resistance for clear click feedback when conditions permit.
Solution Approach 2:
By making the rotary resistance dynamically adjustable, the system can adapt to different operational conditions. When gloves are worn, the resistance can be reduced for easier operation; when hands are bare, the resistance can be increased for more distinct click perception, thus dynamically optimizing the trade-off between these two requirements.

Function Achieved in This Case
This solution allows for a customizable and adaptable 'click hardness' adjustment, ensuring the turret remains rotatable while allowing users to set the desired rotary resistance, enhancing usability across different user preferences and conditions.
Implementation Method 1
at least one elastic element, in particular a spring, which produces a force acting perpendicular to or obliquely to the rotary axis and loading the at least one detent element

AI summary
An adjusting turret for a long-range optical device, in particular a telescopic sight, includes a rotary cap rotatable about a rotary axis and at least one locking ring having a toothing and at least one locking element cooperating permanently with the toothing. The at least one locking element is moved by rotating the rotary cap out of a first, non-locked engagement position, in which the at least one locking element is in engagement with a first portion of the toothing of the at least one locking ring, overcoming a rotary resistance produced by the force of at least one elastic element into a second, non-locked engagement position, in which the at least one locking element is moved into engagement with a second, portion of the toothing of the locking ring. The adjusting turret includes at least one adjusting element in particular for the stepless adjustment of the rotary resistance.
