Night Vision Mount Insert for Day Sight Image Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for attaching night vision devices to rifles often result in an unwanted offset between the image output and the optical field of view, making it difficult to align the night vision image centrally within the day sight's field of view, especially when the night vision device is mounted in front of the day sight.
Innovation Solution
A mounting apparatus with a clamp and insert system that allows adjustable positioning of the night vision device relative to the day sight along the x and y axes, using a concave inner surface of the clamp and a convex outer surface of the insert, which can be secured in place with radial pressure and fastenings, ensuring proper alignment of the night vision image within the day sight's field of view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the night vision device is attached to the front end of the day sight using a fixed clamp, then the device is securely mounted, but an unwanted offset occurs between the image output and the optical field of view
Solution Approach 1:
The mounting apparatus transitions from a fixed rigid connection to a dynamic adjustable connection. The insert can be positioned at different locations along the longitudinal axis of the clamp, allowing the night vision device to be aligned precisely with the day sight's optical field of view while maintaining secure mounting through the clamp's gripping mechanism.
Solution Approach 2:
The insert acts as an intermediary element between the clamp and the night vision device. This intermediate component provides the necessary adjustment capability, allowing independent optimization of both secure mounting (through the clamp) and alignment precision (through the insert's position along the longitudinal axis).
2Strength
If the night vision device is attached directly to the rifle body, then the device is supported directly by the rifle, but alignment with the day sight becomes difficult
Solution Approach 1:
The mounting apparatus serves as an intermediary system between the rifle body and the night vision device. It combines the stable support of direct rifle mounting with the alignment capabilities of front-attachment systems, allowing the device to be securely supported while precisely aligned with the day sight through adjustable positioning.
3Device complexity
If a fixed position mounting system is used, then the structure is simple, but the image cannot be aligned centrally within the field of view
Solution Approach 1:
The mounting system incorporates controlled adjustability through the insert's movable position along the longitudinal axis. This provides the necessary alignment capability while maintaining relative structural simplicity, as the adjustment mechanism is integrated into the existing clamp and insert design rather than requiring complex external adjustment systems.

AI summary
Some embodiments of the present invention provide a mounting apparatus for supporting a device such as a night vision (30) device comprises a clamp (60) having an opening for receiving an end portion of the night vision device. The clamp has a concave inner surface (68) when viewed in cross-section and a longitudinal axis (54). An insert (70) is configured to locate within the opening of the clamp (60). The insert (70) has an inner surface (72) for locating against the night vision device (30), or the insert (70) being integrated with the night vision device (30), the insert (70) having a convex outer surface (78) when viewed in cross-section, wherein the convex outer surface (78) of the insert is movable across the concave inner surface (68) of the clamp to allow adjustment of a position of the insert (70) relative to the clamp (60) about an x axis and/or a y axis which are mutually perpendicular to the longitudinal axis (54). The clamp (60) is configured to secure the insert (70) in a selected position.
