Reflex Sight Multiple Aiming Marks Dichroic Optics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional reflex sights are limited to a single aiming feature, making them difficult to adjust for different types of ammunition and ranges, and require multiple sights for dual-barrel firearms, which is impractical due to space and weight constraints.
Innovation Solution
A reflex sight with multiple aiming marks, featuring two optical elements with dichroic coatings and light sources positioned at focal points, allowing users to select and adjust aiming marks for different ammunition types and ranges through a selector switch and independent adjustment mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single conventional reflex sight is used, then the device complexity is reduced, but the adaptability to different ammunition types and ranges is limited
Solution Approach 1:
The reflex sight is divided into multiple independent optical channels, each with its own light source, reflector, and aiming mark. Each channel can be independently adjusted and selected, allowing the single device to provide multiple aiming configurations for different ammunition types and ranges while maintaining manageable complexity through modular design
Solution Approach 2:
The reflex sight is designed to perform multiple functions by incorporating several light sources and reflectors that can be selectively activated. The system can switch between different aiming marks (e.g., first aiming mark for subsonic ammunition, second aiming mark for supersonic ammunition) within a single device, eliminating the need for multiple separate sights
2Adaptability or versatility
If multiple conventional sights are used for dual-barrel firearms, then the adaptability to different barrels is improved, but the weight and mounting area requirements increase
Solution Approach 1:
The patent combines multiple sight functions into a single integrated reflex sight unit. By merging multiple light sources, reflectors, and aiming mark systems into one device, the weight and mounting area requirements are significantly reduced compared to using multiple separate conventional sights, while still providing adaptability to different barrels through selective activation of appropriate aiming marks
3Measurement precision
If a single aiming mark is used, then the device complexity is reduced, but the measurement precision for different ranges deteriorates
Solution Approach 1:
The reflex sight incorporates adjustable aiming marks that can be dynamically selected and positioned. The light sources and reflectors are arranged to allow independent adjustment of each aiming mark's position and illumination, enabling precise alignment for different ranges and ammunition types while maintaining a relatively simple overall device structure through shared optical components

AI summary
A reflex sight with multiple aiming marks has a body having a forward end extending in forward direction and an opposed rearward end extending in a rearward direction, a first optical element having a first concave surface facing in the rearward direction, the first concave surface having a first focal point, a second optical element having a second concave surface facing in the rearward direction, the second concave surface having a second focal point, a first emitter proximate the first focal point and spaced apart from the second focal point, a second emitter proximate the second focal point and spaced apart from the first focal point, and the first optical element being forward of the second optical element. The first and second emitters may both be rearward of the first and second optical elements. The second emitter may be spaced apart rearwardly from the first emitter.
