Rear Gunsight Light Collector for Precise Sight Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm sights do not effectively provide a clear and adjustable reference point for alignment, especially when the firearm is not perfectly aimed, leading to potential misalignment and reduced accuracy.
Innovation Solution
A rear gunsight system that includes an elongate light collector with a nontransparent light blocking tube and a convex lens, allowing for an adjustable alignment with a straight sight line that ensures a bright shining reference point appears only when the sight is optimally aligned, enhancing visibility and accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a traditional front gunsight is used, then the sight is simple in structure, but it does not provide an effective reference point for alignment when the firearm is not perfectly aimed
Solution Approach 1:
The patent places the light collector inside the hollow space of the light blocking tube, creating a nested structure where one component is contained within another. This nesting approach provides the reference point functionality while maintaining a compact and relatively simple overall structure.
Solution Approach 2:
The light collector acts as an intermediary element that receives light from the light source and directs it through the hollow space to create the reference point. This intermediary component enables the alignment reference function without requiring a completely complex optical system.
2Ease of operation
If a light source is added to create a reference point, then alignment visibility is improved, but the device complexity increases
Solution Approach 1:
The light blocking tube serves multiple functions: it blocks extraneous light, defines the hollow space, and structurally supports the light collector. This self-service approach reduces the need for additional separate components, thereby limiting the increase in device complexity while still providing the light-based reference point.
Solution Approach 2:
The light blocking tube is designed to perform multiple functions simultaneously - structural support, light blocking, and defining the optical path. This multi-functionality reduces the total number of components needed, making the complexity increase manageable while achieving improved alignment visibility.
3Measurement precision
If the light collector is positioned to create a bright reference point, then alignment accuracy is enhanced, but the manufacturing precision requirements increase
Solution Approach 1:
The optical path is segmented into distinct zones: the light source area, the hollow space, and the light collector position. This segmentation allows each component to be manufactured and positioned independently with standard tolerances, reducing the overall manufacturing precision requirements while still achieving accurate alignment reference.

AI summary
A rear gunsight connects to a rear of a gun. The rear gunsight includes a sight longitudinal axis. The rear gunsight and a straight sight line are optimally aligned relative to each other when the sight longitudinal axis is substantially coextensive with the straight sight line. Further when the rear gunsight and straight sight line are optimally aligned, the straight sight line extends through a lens of the rear gunsight and through an end face of an elongated light collector of the rear gunsight. When the rear gunsight and the straight sight line are optimally aligned relative to each other, a bright reference point appears in a hollow tube of the rear gunsight.
