Elongated Firearm Rear Sight with Light Gathering Rods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional firearm sights, such as blade and notch configurations and hooded designs, often cause users to aim too high and result in double vision, impairing depth perception, and require a power source for illumination, leading to potential failure.
Innovation Solution
An elongated rear sight with light gathering rods, such as fiber optic rods, positioned within an elongated aperture that aligns with the firearm barrel, allowing users to aim accurately without power sources and maintaining depth perception with both eyes open.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If blade and notch sights or hooded designs are used, then the firearm can be aimed, but the user experiences double vision and impaired depth perception
Solution Approach 1:
The rear sight is divided into multiple discrete elements (first rear sight element, second rear sight element, third rear sight element) positioned at different locations within the aperture. This segmentation allows each element to serve a specific function in guiding the user's eye, reducing double vision while maintaining aiming capability.
Solution Approach 2:
The invention transitions from traditional two-dimensional blade/notch or hood designs to a three-dimensional aperture configuration with multiple sight elements positioned in space. This dimensional change creates a more comprehensive visual reference system that accommodates both eyes open while providing accurate aiming alignment.
2Ease of operation
If blade and notch sights or hooded designs are used, then the firearm can be aimed, but the user aims too high resulting in inaccurate shots
Solution Approach 1:
The aperture is divided into multiple zones with specific sight elements positioned in each zone (top, bottom, left, right portions). This segmentation provides the user's eye with multiple reference points that guide proper alignment, preventing the common error of aiming too high and improving shot accuracy.
Solution Approach 2:
The multiple rear sight elements act as intermediary reference points between the front sight and the target. These intermediaries provide visual cues that guide the user's eye along the correct alignment path, ensuring accurate aiming without requiring the user to interpret complex sight pictures.
3Illumination intensity
If illuminated sights with power sources are used, then aiming assistance is provided, but the sights are prone to failure when power dies
Solution Approach 1:
The rear sight elements are designed to be naturally visible through the aperture without requiring external power sources. The elongated aperture itself provides the illumination and visibility function, eliminating the need for batteries or power supplies and ensuring continuous reliable operation.
Solution Approach 2:
The invention extracts and eliminates the power source component from the sight system. By removing the vulnerable power source, the design achieves inherent reliability while maintaining all necessary aiming functions through the passive optical structure of the aperture and sight elements.
4Ease of operation
If traditional rear sights are used, then the firearm can be aimed, but the sight profile is short and requires closing one eye
Solution Approach 1:
The invention extends the sight profile in the longitudinal dimension by positioning multiple rear sight elements at different distances within the aperture. This creates an elongated three-dimensional sight structure that naturally guides the user's eye along its length, enabling accurate aiming with both eyes open and eliminating the need to close one eye.
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
The elongated rear sight improves aiming speed and accuracy by channeling the user's vision directly to the target, eliminating the need for power sources and reducing double vision, enabling precise aiming with both eyes open.
Implementation Method 1
The first elongated rod, second elongated rod, and third elongated rod may be light gathering rods that glow in the presence of light. The light gathering rods may be fiber optic rods.

AI summary
An elongated rear sight for a firearm is described herein. The elongated sight includes an elongated aperture bounded by a top portion, a first side portion, and a second side portion. A first elongated rod is interior and approximate to the top portion, and extends along a length of the top portion. A second elongated rod is interior and approximate to the first side portion, and extends along a length of the first side portion. A third elongated rod is interior and approximate to the second side portion, and extends along a length of the second side portion. The elongated rods may be light gathering rods that glow in the presence of light. The elongated aperture channels a user's eye(s) towards the target, while the three elongated rods are used to align with a front sight of the firearm to aim towards a target.
