Gun Sighting Device Top-Mounted Laser Alignment
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 with non-uniform cross-sections, 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 with a first light source, such as a laser, and a second light source, like an infra-red or visible light, spaced apart with a mechanical sight in between, mounted on the top surface of the gun, using a housing made of metal with a connective portion and set screws for secure attachment, allowing for single-hand operation and proper holstering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the laser sight is mounted on the trigger guard, then the laser can be attached to the weapon, but the complex three-dimensional shape with non-uniform cross-sections makes it difficult to mount, align and use
Solution Approach 1:
The patent extracts the laser sight from the complex trigger guard area and relocates it to the simpler rail system on the gun. This allows the laser to be mounted on a flat, uniform surface rather than contending with the three-dimensional non-uniform cross-section of the trigger guard, significantly simplifying mounting and alignment procedures
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 becomes difficult or impossible to holster and requires two hands to operate
Solution Approach 1:
The patent repositions the laser sight from a below-barrel location to a top-surface location on the gun. This dimensional change allows the laser to be mounted higher on the weapon, clearing the way for proper holstering and enabling single-hand operation while maintaining all mounting benefits
3Ease of operation
If the laser sight is mounted on the top surface of the gun, then the gun can be easily holstered and operated with one hand, but the laser may interfere with the mechanical sight
Solution Approach 1:
The patent incorporates specific alignment features directly into the laser housing at the local mounting position. These features include alignment slots and adjustment mechanisms that are built into the laser unit itself, allowing for precise alignment with the mechanical sight without requiring complex external alignment procedures or modifying the gun's existing sight system
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 easy mounting, alignment, and operation of the laser sight on a gun without obstructing holstering, allowing for single-hand use and improved usability by maintaining a compact size and efficient power management.
Implementation Method 1
a light-emitting sighting device, particularly a laser... The laser projects a narrow beam of light in a direction generally parallel to the gun's bore
Implementation Method 2
the second light source may be an infra-red light; a flashlight; a LED flashlight; or a visible light or infra-red laser

AI summary
A sighting device (10) is mountable to a gun (2000). The device 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 (2000) so that the laser is juxtaposed either the top surface of the gun (2000) or a side surface of the gun (2000). In one embodiment, the sighting device (10) includes a bottom rail mountable in a slot (2010) on the gun (2000), wherein the slot (2010) is preferably positioned on the top surface of the gun (2000). The sighting device (10) may also include a mechanical sight that functions as the rear mechanical sight on the gun and/or a secondary light source.
