Adjustable Rear Gun Sight Aperture Module Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional firearm sighting systems lack adjustability to effectively compensate for elevation, windage, projectile type, and charge variations, leading to potential targeting errors due to recoil-induced movement and misalignment.
Innovation Solution
An adjustable rear gun sight with a vertically movable aperture module, secured by springs and an adjustment screw, which is designed to resist recoil forces and maintain alignment, optionally incorporating a tritium module for illumination in dark conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the rear sight is made adjustable to compensate for elevation and other factors, then the adaptability and precision are improved, but the device complexity increases
Solution Approach 1:
The aperture module is made movable relative to the base through a sliding mechanism, allowing dynamic adjustment of the rear sight position. The module can move vertically along the base to change elevation compensation while maintaining a relatively simple overall structure. This dynamic design enables adaptability without requiring complex mechanical systems.
Solution Approach 2:
The sight system is divided into two main segments: a fixed base and a movable aperture module. This segmentation allows the adjustment function to be isolated to the module component, keeping the base simple and reducing overall device complexity while still providing the needed adjustability for different shooting conditions.
2Ease of operation
If the aperture module is made movable to allow adjustment, then the ease of operation is improved, but the stability under recoil forces deteriorates
Solution Approach 1:
The adjustment function is extracted into a separate aperture module that can be independently adjusted and then locked in position. Once adjusted, the module is secured relative to the base, separating the adjustment operation from the stability requirement during firing. This allows easy adjustment before shooting while maintaining stability during recoil.
Solution Approach 2:
The aperture module is adjusted to the desired position before firing, and then secured in place. This preliminary adjustment and securing action ensures that the sight is properly configured before recoil forces are applied, maintaining alignment stability during firing while preserving ease of adjustment when needed.
3Ease of operation
If springs are added to bias the aperture module away from the base, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The springs provide a self-service function by automatically biasing the aperture module away from the base, creating natural tension that facilitates smooth adjustment movement. The springs continuously apply force to maintain the module in an adjusted position without requiring additional active components or complex mechanisms, adding minimal complexity while significantly improving operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides precise elevation adjustments while resisting recoil-induced movement, reducing targeting errors and enhancing usability in various lighting conditions, with a lighter and more compact design compared to conventional sights.
Implementation Method 1
The aperture module is held to the base by an adjustment screw and is biased away from the base by at least one, but preferably two springs
Implementation Method 2
the aperture module includes a recess for receiving a tritium module which emits light through a port formed in the module in order to illuminate the gun sight aperture or groove

AI summary
A rear gun sight mountable to a firearm that includes an aperture module defining a gun sight aperture and a base. The base defines a recess for receiving the aperture module and the aperture module includes ribs that are slidably received by associated recess in the base to constrict the aperture module to relative rectilinear movement with respect to the base. At least one spring acts between the base and the aperture module. An adjustment member couples the module to the base such that rotation of the adjustment member moves the module towards and away from the base depending on direction of rotation. A detent resists uncontrolled rotation of the adjustment member. The aperture module includes a recess for receiving a light emitting member such as a tritium module.
