Rear-Mounted Reflex Sight for Firearm Balance and Dry-Fire Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gun sights, particularly occluded eye gun sights, face challenges in providing effective dry fire training due to lack of real-time user feedback on accuracy, and their mounting arrangements can disrupt the balance and usability of firearms.
Innovation Solution
A reflex sight is positioned behind the barrel of a handgun, centered on its longitudinal axis, using a reflective or refractive optical system to project a collimated beam of light as an illuminated reticle, allowing binocular vision and minimizing interference with conventional sights, while incorporating adjustable brightness and intelligent power control features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an occluded eye gun sight (OEG) is mounted on the side or top of the receiver, then the sight provides fast target acquisition and illuminated dot feedback, but it disrupts the firearm's balance and interferes with conventional open sights
Solution Approach 1:
The patent moves the sight mounting location from the traditional top or side of the receiver to the rear end of the weapon, positioning it in a different spatial dimension. This rear mounting location is behind the barrel and does not interfere with the balance or conventional sights, while still providing the illuminated dot feedback function
2Ease of operation
If a reflex sight projects an illuminated reticle superimposed over the field of view, then the user sees the target and reticle simultaneously, but the sight becomes complex and interferes with conventional sights
Solution Approach 1:
The patent extracts the illuminated reticle projection function from a complex optical system and implements it using a simpler arrangement with a light source and optical elements positioned at the rear of the weapon. This separates the illumination function from the main optical path, reducing overall system complexity
3Device complexity
If existing gun sights are used for dry fire training, then the structure is simple, but there is no real-time user feedback on aiming accuracy
Solution Approach 1:
The patent incorporates an illuminated reticle that provides real-time visual feedback to the user about aiming accuracy. The illuminated dot or pattern allows the user to see whether the firearm is properly aligned with the target during dry fire training, compensating for the lack of live ammunition feedback

Function Achieved in This Case
Enables accurate and efficient dry fire training with real-time feedback on aiming accuracy, maintaining the firearm's balance and usability, and allowing for fast target acquisition in combat situations.
Implementation Method 1
a light source. The sight also includes an optical system that projects an approximately collimated beam of light from the light source toward a user of the sight to create an image of an illuminated reticle
Implementation Method 2
uses a refractive or reflective optical system to generate a collimated beam of light
Implementation Method 3
uses a refractive or reflective optical system to generate a collimated beam of light

AI summary
Various gun sights for firearms and related methods of use are provided. In one embodiment, the sight includes an apparatus adapted to be mounted at a rear end of a firearm and arranged to occlude one eye of a user of the firearm and to generate an illuminated dot that is disposed such that it is generally centered on the longitudinal axis of the barrel of the firearm. The gun sight produces a collimated beam of light that creates an image of an illuminated dot by either a refractive method or a reflective method. In use, a dominant eye of the user is occluded by the sight and the other eye of the user is focused on the target. The user then adjusts the position of the gun relative to the target such that the user perceives the illuminated dot of the sight to be positioned on the target.
