Rear Firearm Sight Slide Elevator for One-Handed Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rear firearm sight elevators face issues such as obstructing the sight path, being prone to unintentional lateral movements, requiring two-handed operation, and having limited grip surface area, making it difficult to adjust sight elevation settings quickly and effectively.
Innovation Solution
A rear firearm sight slide elevator with parallel fins and a smooth ramp that allows one-handed adjustment, providing a large grip surface, clear sight markings, and a channel for unobstructed sight path, enabling easy and quick elevation changes without losing sight of the rear sight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If a single-step rear sight elevator is made taller to provide higher sight elevation settings, then the sight elevation capability is improved, but the elevator obstructs the sight path
Solution Approach 1:
The elevator is divided into multiple fins (first fin, second fin, etc.) that are positioned at different locations. This segmentation allows the elevation function to be distributed across multiple smaller elements rather than one large obstructive structure, enabling higher sight elevation without blocking the sight path.
Solution Approach 2:
Instead of increasing elevation in a single vertical dimension which causes obstruction, the invention positions multiple fins at different lateral locations. This transforms the problem from a single-dimension height issue to a multi-dimensional arrangement where elevation is achieved through spatial distribution rather than vertical stacking.
2Length of stationary object
If a double-step rear sight elevator is used to provide higher sight elevation settings, then the sight elevation capability is improved, but the elevator becomes exposed from under the rear sight and is prone to unintentional lateral movements
Solution Approach 1:
The elevator structure is segmented into multiple fins positioned at different locations rather than using a single double-step structure. This segmentation distributes the elevation function across multiple stable elements, reducing lateral exposure and minimizing unintentional movements while maintaining high sight elevation capability.
3Adaptability or versatility
If single- or double-step rear sight elevators are used, then sight elevation adjustment is possible, but the sight elevation steps are difficult to force under the rear sight and require two-handed operation
Solution Approach 1:
The fins are designed with specific local characteristics including ridges on inner walls and sight markings on outer walls. These local quality features provide enhanced grip surfaces and visual feedback, making the elevation adjustment process easier and more intuitive while allowing one-handed operation.
Solution Approach 2:
The invention replaces the traditional step-based mechanical adjustment system with a slide-based system where fins can be smoothly moved along the rail. This substitution eliminates the need to force steps under the rear sight and enables easier one-handed operation while maintaining full elevation adjustment capability.
4Adaptability or versatility
If single- or double-step rear sight elevators are used, then sight elevation adjustment is possible, but the exposed surface area is small making them difficult to contact and grip
Solution Approach 1:
The fins are designed with enhanced local surface features including ridges on inner walls and sight markings on outer walls. These local quality improvements significantly increase the effective grip surface area, making it easier to contact and manipulate the elevation mechanism even when wearing gloves or with cold fingers.
5Adaptability or versatility
If single- or double-step rear sight elevators are used, then sight elevation adjustment is possible, but there is little exposed surface area making it unfeasible to put detailed and legible sight elevation reference markings on them
Solution Approach 1:
The elevation system is segmented into multiple fins, each providing additional surface area. This segmentation creates multiple opportunities to display sight elevation reference markings, ensuring that detailed and legible markings can be clearly visible while maintaining full elevation adjustment functionality.
Solution Approach 2:
The outer walls of the fins are designed with specific local quality features including large flat surfaces dedicated to displaying sight elevation reference markings. These enhanced surface areas ensure that detailed markings are legible and easily readable, preventing information loss while maintaining adjustment capability.

AI summary
A rear firearm sight slide elevator with a base member that is configured to surround part of a firearm barrel and has a first wing on one side and a second wing on another side of the front part of the base member, first and second fins that are parallel to each other and situated at least in part on top of the base member, and a smooth ramp that is situated on a central portion of the base member between the fins. The ramp increases in height from front to back and has a central channel that is configured to provide a sight path from the user to the front sight on the firearm. The inner wall of the first and/or second fin includes a plurality of vertically oriented ridges. The outer wall of at least one of the first and second fins displays a plurality of sight markings.
