Firearm Scope Push-In Windage Elevation Reset Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional firearm scopes lack an efficient and user-friendly mechanism for adjusting windage and elevation settings, which can lead to inaccuracies in aiming due to the complexity and difficulty in resetting these adjustments.
Innovation Solution
A scope design featuring a main tube with imaging optics and a movable optic assembly, utilizing a rotatable adjustment knob and threaded member biased by a biasing element, allowing for precise adjustments in windage and elevation with a mechanism that disengages for easy resetting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional windage and elevation controls are used, then the scope can be adjusted for aiming, but the mechanism becomes complex and difficult to reset
Solution Approach 1:
The adjustment knob transitions between two dynamic states: engaged and disengaged. When engaged, the knob drives the threaded member for precise adjustment. When disengaged (pushed in), the knob allows free rotation for resetting without driving the threaded member. This dynamic state change simplifies the resetting operation while maintaining adjustment precision.
Solution Approach 2:
The adjustment mechanism is segmented into distinct functional components: the adjustment knob, the threaded member, and the biasing element. This segmentation allows the knob to independently control engagement/disengagement from the threaded member, separating the adjustment function from the resetting function and reducing overall system complexity.
2Measurement precision
If a threaded member is used for precise adjustment, then positioning accuracy is improved, but the mechanism requires more components increasing complexity
Solution Approach 1:
Multiple functions are merged into the adjustment knob: it serves as the user interface for rotation, the actuator for engagement/disengagement, and the driver for the threaded member. This consolidation reduces the number of separate components needed while maintaining precise adjustment capability through the threaded member.
Solution Approach 2:
The biasing element automatically maintains engagement between the adjustment knob and threaded member, eliminating the need for additional locking mechanisms or complex control systems. The spring self-regulates the engagement state based on the knob position, simplifying the overall mechanism while ensuring precise adjustment transmission.

AI summary
Certain embodiments described herein comprise a scope for mounting on a firearm to provide a sight. This scope is adjustable in at least one of elevation and windage. The scope comprises a main tube, imaging optics in the main tube, a movable optic assembly that holds at least a portion of the optics; and an adjustable mechanism configured to adjust the position of the movable optics assembly. The adjustment mechanism comprises a rotatable adjustment knob, an adjustment screw, and a biasing element that biases the adjustment screw with respect to the adjustment knob. In an engagement position the adjustment knob drivingly engages with the adjustment screw such that rotation of the knob causes rotation of the adjustment screw, and in a depressed position the knob disengages the adjustment screw.
