Solution Overview
Problem
Existing adjustable sights for firearms are complex, heavy, and lack a mechanism to prevent unintentional lateral movement while allowing intentional adjustment, which is crucial for combat situations.
Innovation Solution
A compact, lightweight adjustable sight assembly with a front sight support element that includes a spring-loaded adjustment element and a torque-transferring axle mechanism, allowing vertical and lateral adjustments with a keyhole opening to prevent unintentional lateral movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If existing adjustable sights are used, then sighting functionality is provided, but the device complexity and weight increase
Solution Approach 1:
The sight assembly is divided into separate functional components: a sight element that can be adjusted independently, a mounting element with distinct adjustment mechanisms for elevation and windage, and a firearm body. This segmentation allows each component to be optimized for its specific function, reducing overall complexity while maintaining reliability.
Solution Approach 2:
The mounting element serves multiple functions: it provides structural support for the sight element, enables elevation adjustment through a first adjustment mechanism, enables windage adjustment through a second adjustment mechanism, and secures the sight element in adjusted positions. This multi-functionality reduces the need for separate components, simplifying the overall assembly.
2Weight of moving object
If existing adjustable sights are used, then adjustment functionality is provided, but the weight increases
Solution Approach 1:
The patent replaces complex traditional mechanical adjustment systems with simplified mechanisms. The first adjustment mechanism for elevation and the second adjustment mechanism for windage use streamlined components rather than elaborate gear systems, reducing weight while maintaining ease of operation. The sight element can be adjusted independently without requiring complex locking and unlocking sequences.
Solution Approach 2:
The sight assembly incorporates dynamic adjustment capabilities where the sight element can be moved independently in elevation and windage directions. The adjustment mechanisms allow for quick, on-the-fly adjustments during combat situations, providing ease of operation. The independent adjustability enables the sight to adapt dynamically to different shooting conditions and ranges.
3Reliability
If existing adjustable sights are used, then lateral adjustment is possible, but unintentional movement cannot be prevented
Solution Approach 1:
The second adjustment mechanism for windage adjustment is designed to be self-locking, preventing unintentional lateral movement of the sight element. The mechanism inherently maintains the adjusted position without requiring additional locking steps or complex securing procedures. This self-service feature ensures sight position stability while keeping the adjustment process simple and straightforward.
Solution Approach 2:
The mounting element acts as an intermediary between the sight element and the firearm body, providing a stable interface that prevents unintentional lateral movement. The mounting element's structure includes features that securely hold the sight element in the adjusted windage position, mediating between the adjustment mechanism and the sight element to ensure both stability and ease of adjustment.

AI summary
In one example, the disclosure relates to adjustable flip up sight assembly that can be adjusted vertically and laterally in particular, for an automatic firearm, comprising a front sight support element that is supported by an axle on a mount, in particular such that they can pivot thereon, wherein the front sight support element has an adjustment element supported on a spring element and releasably connected to a front sight, which contains a keyhole type opening through which the axle is inserted, wherein the adjustment element can be moved in relation to the axle against the spring force between two positions inside the front sight support element such that the keyhole opening prevents a lateral movement of the front sight support element along the axle when engaged with the axle, and allows the lateral adjustment of the front sight support element in a released position.
