Handgun Slide Integrated Red Dot Sight
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current red-dot sights for handguns are often mounted via a machining process that requires a separate plate, which can lead to reduced accuracy due to the increased distance between the sight line and the bore axis, and may become loose over time, requiring additional components and potentially obstructing the view.
Innovation Solution
A handgun design with a lens and light source integrated into the slide, eliminating the need for a mounting plate, featuring a reflector for backup functionality and adjustable light source positioning, allowing for improved accuracy and ease of lens replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mounting plate is used to mount the sight on the slide, then the sight can be installed and replaced, but the sight line is raised away from the bore axis, reducing shooting accuracy
Solution Approach 1:
The sight assembly is merged directly with the slide by integrating the lens and light source into recesses formed in the slide itself, eliminating the separate mounting plate. This integration lowers the sight line to align with the bore axis, improving accuracy while reducing structural complexity.
2Reliability
If the sight is mounted using screws and a mounting plate, then the sight can be installed, but it may become loose over time
Solution Approach 1:
The lens and light source are integrated directly into the slide through recesses, eliminating screws and mounting plates. This merger ensures the sight components cannot become loose while simplifying the assembly process to require fewer fastening operations.
3Adaptability or versatility
If a mounting plate is used, then multiple sight options can be accommodated, but additional components are required and the view may be obstructed
Solution Approach 1:
The sight assembly is merged into the slide structure with recesses for the lens and light source, eliminating the mounting plate and reducing the total component count. The integrated design provides an unobstructed view while maintaining adaptability through configurable recess arrangements.
4Ease of repair
If the lens is fixed to the mounting plate, then the sight assembly is complete, but the lens cannot be easily replaced if damaged
Solution Approach 1:
The lens is segmented as a separate replaceable component housed in a recess in the slide, distinct from the light source and other components. This segmentation allows the lens to be easily removed and replaced independently, improving repairability while maintaining a simple integrated structure.
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
This design lowers the sight line closer to the bore axis, enhancing shooting accuracy, reduces the likelihood of the sight becoming loose, minimizes assembly components, and provides a backup reflector for continued functionality even if the lens is damaged, while maintaining a clear view of the target.
Implementation Method 1
a light source associated with the slide and positioned at the focal point of the lens, such that when a user aims the handgun at the target, light from the light source reflects from the lens to the user's eye, providing an infinity image of an illuminated reticle over the target
Implementation Method 2
a lens removably mounted on the slide; and a light source associated with the slide and positioned at the focal point of the lens
Implementation Method 3
a reflector associated with the slide, wherein the light source is positioned at the focal point of the reflector; and wherein the reflector is arranged to provide a continuous reflecting surface with the lens; such that when the user aims the handgun at the target, light from the light source reflects from the reflector and the lens to the user's eye
Data Source
AI summary
There is provided a handgun for aiming at a target. The handgun comprises a handgun body, a slide arranged to move with respect to the handgun body, a lens removably mounted on the slide, and a light source associated with the slide and positioned at the focal point of the lens, such that when a user aims the handgun at the target, light from the light source reflects from the lens to the user's eye, providing an infinity image of an illuminated dot over the target. The lens is removable from both of the slide and the light source.
