Firearm Diopter Sight Single-Actuator Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rear sights for firearms are cumbersome to adjust, especially when shooting in a prone position, as they require operating two separate actuating elements, which can lead to loss of position during adjustment.
Innovation Solution
A diopter design featuring a frame with a common axis for two sliding blocks, where one block can move relative to the other to change distance, allowing vertical adjustment, and simultaneous movement along the axis for horizontal adjustment, with a wedge-shaped extension and inclined plane for stable vertical movement, and a selective entrainment device for intuitive operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two separate actuating elements are provided for horizontal and vertical movement, then the optical unit can be adjusted in both directions, but the operation becomes cumbersome and position can be lost during adjustment
Solution Approach 1:
The patent combines two separate actuating elements into a single integrated actuating element that controls both horizontal and vertical movement of the optical unit. This single element simultaneously actuates both the horizontal adjustment mechanism and the vertical adjustment mechanism, eliminating the need for separate controls and preventing position loss during adjustment.
Solution Approach 2:
The single actuating element performs multiple functions by simultaneously controlling both horizontal and vertical adjustment of the optical unit. This multi-functional design allows one element to replace what would traditionally require two separate elements, improving ease of operation while maintaining full adjustment capability.
2Adaptability or versatility
If a compound slide with two actuating elements is used, then both horizontal and vertical adjustment are possible, but the device complexity increases
Solution Approach 1:
The patent merges the compound slide mechanism into a simplified single-element actuation system. Instead of maintaining separate horizontal and vertical adjustment mechanisms with independent actuating elements, the invention uses one actuating element that simultaneously controls both adjustment directions through a unified mechanical linkage.
3Stability of the object's composition
If set screws are used to fix horizontal position, then horizontal positioning is stable, but the adjustment process becomes time-consuming and complex
Solution Approach 1:
The patent replaces static set screw fixation with a dynamic adjustment mechanism that allows continuous horizontal and vertical movement of the optical unit through a single actuating element. The mechanism provides stable positioning through its mechanical design while enabling rapid adjustment without the need for time-consuming set screw operations.

AI summary
A diopter sight (1) for a firearm (2), comprising: a frame (3) attachable to the firearm (2), an optical unit (4) with a viewing aperture (5), and an adjusting device (6) for horizontal and vertical movement of the optical unit (4) relative to the frame (3), wherein the adjusting device (6) has a first and second cam block (7, 8) arranged along a common axis (10), wherein the first cam block (7) and the second cam block (8) are selectively (i) movable relative to each other along the common axis (10) via an actuating device (11), such that the distance between the two cam blocks (7, 8) changes, thereby making the optical unit (4) vertically movable relative to the frame (3), or (ii) movable together along the common axis (10) without substantially changing the distance between the two cam blocks (7, 8).which allows the optical unit (4) to be moved horizontally relative to the frame (3).
