Slot-Mounted Laser Sighting Device for Single-Hand Gun Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Trigger-guard mounted laser sights on guns are complex to mount, align, and use due to their three-dimensional shapes, making it difficult to holster the gun and requiring two hands to operate, especially when positioned below the gun barrel.
Innovation Solution
A sighting device mounted in a slot on the top surface of the gun, featuring a laser module, power source, and mechanical sight, allowing for single-hand operation and proper holstering, with adjustable light source positioning and power management to conserve battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the laser sight is mounted on the trigger guard, then the laser can be positioned close to the trigger for operation, but the complex three-dimensional shape of the trigger guard makes mounting and alignment difficult and the gun difficult to holster
Solution Approach 1:
The laser sight is extracted from the trigger guard mounting location and relocated to the barrel shroud or handguard area. This removes the conflict between the laser mounting and the trigger guard's complex three-dimensional shape, allowing the gun to be holstered normally while the laser remains accessible for operation.
Solution Approach 2:
The laser sight is repositioned from the vertical trigger guard area to the horizontal barrel shroud or handguard area. This dimensional relocation provides a flat, accessible surface for mounting while maintaining ease of operation and allowing proper holstering.
2Ease of manufacture
If the laser sight is positioned below the gun barrel, then the laser can be mounted on the picatinny rail, but the gun requires two hands to operate and cannot be holstered
Solution Approach 1:
The laser sight is repositioned from the lower picatinny rail area to the upper barrel shroud or handguard area. This vertical relocation allows the gun to be holstered normally and operated with one hand while still providing stable mounting on a flat surface.
Solution Approach 2:
The barrel shroud or handguard area serves dual purposes: it provides a stable mounting surface for the laser sight and maintains compatibility with normal gun handling, holstering, and operation. This multi-functional location resolves the conflict between mounting stability and operational convenience.
3Ease of operation
If the laser sight is mounted on the trigger guard, then the laser can be operated near the trigger, but adjusting the laser requires two hands
Solution Approach 1:
The laser sight assembly is designed as a self-contained unit with integrated adjustment mechanisms. The adjustment controls are segmented and positioned on the side or top of the laser housing, allowing one-handed operation while maintaining stable mounting on the barrel shroud or handguard.
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
Enables efficient alignment and sighting of a gun with a compact design that allows for single-hand operation and easy holstering, improving usability and convenience.
Implementation Method 1
Lasers are the preferred means of generating light beams for weapon sighting because they have comparatively high intensity and can be focused into a narrow beam with a very small divergence angle so they produce a small, bright spot on a target.
Implementation Method 2
a secondary light source, preferably the secondary light source may be an infra-red light; a flashlight, preferably an LED flashlight

AI summary
A sighting device (10) is mountable to a gun. The device (10) includes a light source (20) (preferably a laser), a power source (30) connectable to the light source (20) and a mount (102) attachable to the gun so that the laser is juxtaposed either the top surface of the gun or a side surface of the gun. In one embodiment, the sighting device (10) includes a bottom rail (102) mountable in a slot on the gun, wherein the slot is preferably positioned on the top surface of the gun. The sighting device (10) may also include a mechanical sight (2005) that functions as the rear mechanical sight on the gun and/or a secondary light source.
