Adjustable Headgear Mount for Night Vision Dovetail Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing night vision device mounting assemblies for headgear often lack a universal fit, leading to instability and potential detachment due to varying sizes of dovetail connectors from different manufacturers.
Innovation Solution
An adjustable headgear mount system featuring a dovetail adapter with an adjustable jaw that can slide longitudinally to accommodate dovetail devices of varying sizes, secured by attachment screws and a clipping lever for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-size dovetail receiver is used, then the mounting structure is simple, but it cannot accommodate dovetail devices of varying sizes from different manufacturers
Solution Approach 1:
The receiver incorporates an adjustable jaw that can move between multiple positions to accommodate different dovetail widths. The jaw is held in place by spring-loaded detent mechanisms that engage with corresponding slots, allowing the receiver to dynamically adapt its internal dimensions to match various dovetail connector sizes from different manufacturers.
Solution Approach 2:
The receiver design allows change in the geometric parameter of the receiver cavity width through adjustable jaw positioning. By modifying the position of the adjustable jaw, the receiver can accommodate dovetail connectors of varying widths while maintaining a secure fit, thus resolving the contradiction between adaptability and structural simplicity.
2Adaptability or versatility
If a universal fit mounting system is designed to accommodate all dovetail sizes, then compatibility improves, but the fit becomes loose and devices may rattle or detach
Solution Approach 1:
The spring-loaded detent mechanism provides dynamic adjustment capability, allowing the receiver to precisely fit different dovetail sizes. When a dovetail is inserted, the spring allows the jaw to move and engage at the appropriate detent position, ensuring a snug fit that prevents rattling and detachment while maintaining universal compatibility.
Solution Approach 2:
The detent mechanism provides mechanical feedback through distinct engagement positions, allowing the user to select the appropriate fit for each dovetail size. This feedback system ensures that the receiver adapts to the specific dovetail being mounted, providing both universal compatibility and secure, stable attachment.
3Adaptability or versatility
If multiple fixed receiver sizes are provided, then compatibility with different manufacturers is achieved, but the device complexity and number of components increases
Solution Approach 1:
The receiver design implements multi-functionality by incorporating an adjustable jaw within a single receiver unit. This single receiver can accommodate multiple dovetail sizes through jaw adjustment, eliminating the need for multiple separate receivers and reducing overall device complexity while maintaining compatibility with different manufacturers.
Solution Approach 2:
The receiver is segmented into adjustable components (jaw, detent mechanism, slots) that work together to provide adaptability. This segmentation allows the single receiver to perform multiple functions by adjusting the jaw position, rather than requiring multiple fixed-size receivers.

AI summary
An adjustable headgear mount device and system is presented. The mount system comprises an adjustable jaw that is adjustable by the user to accommodate a various range of male dovetail parts. A dovetail adapter and the adjustable jaw define a female receiver cavity configured to engage a male dovetail protrusion therein. A user moves the adjustable jaw into a desired position relative to the dovetail adapter and securedly fixes the adjustable jaw in the desired position with at least one attachment screw. In the desired position, a portion of the device engages the male protrusion. The adjustable jaw can be moved to a different position by the user if a different size male dovetail part is desired to be attached to the headgear.
