Compact Reflector Sight Bridge Tunnel Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing closed reflector sights for firearms are bulky and heavy, requiring specific mounts, making them less versatile and harder to interchange with open sights.
Innovation Solution
A compact closed reflector sight design featuring a bridge on the base that creates a tunnel for light to pass through, allowing for repositioning of mounting holes forward, reducing the sight's footprint to match standard open sight mounts, and incorporating a transparent cover to minimize obstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a closed sight design is used to provide robust and weather-proof protection, then reliability is improved, but weight and bulk increase
Solution Approach 1:
The base is segmented into multiple functional portions: a first portion that is covered for structural integrity and weather protection, and a second portion that is exposed to allow light passage and mounting hole positioning. This segmentation enables a compact closed design that maintains reliability while reducing overall weight and bulk compared to traditional enclosed closed sights.
2Reliability
If a closed sight design is used to provide robust and weather-proof protection, then reliability is improved, but the size increases requiring specific mounts
Solution Approach 1:
The mounting holes are repositioned from a conventional rearward location to a forward position on the exposed second portion of the base. This spatial reconfiguration in the longitudinal dimension allows the sight to maintain a compact footprint matching standard open sight mounts while still providing enclosed weather-proof protection through the covered first portion.
3Area of stationary object
If a bridge is incorporated on the base to create a tunnel for light passage, then the footprint is reduced, but the field of view is partially obstructed
Solution Approach 1:
The bridge is designed with selective transparency: it is opaque where it provides structural support and defines the tunnel, but transparent in portions that do not obstruct the field of view. This local differentiation of material properties allows the bridge to fulfill its structural and optical functions simultaneously, minimizing field of view obstruction while maintaining the compact footprint.
