Helmet Vision Mount Tilt Assembly for Consistent Stow Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vision device mounts for helmets lack the ability to maintain consistent stow and deployment positions across different tilt orientations, fail to accommodate various helmet sizes and shapes, and do not provide durable, stable mounting for heavier vision devices like fused panoramic goggles.
Innovation Solution
A vision mounting system with a gantry and carriage assembly featuring a selectable stow position sub-assembly, including shaped apertures and fasteners for multiple stow positions, a tilt adjustment assembly, and fore/aft and vertical adjustment mechanisms, ensuring consistent stow positions and secure mounting across different tilt orientations and helmet configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a traditional mount system is used, then the structure is simple, but the stow position varies with tilt orientation and cannot maintain consistency
Solution Approach 1:
The mount system incorporates a tilt adjustment mechanism that allows the carriage to rotate relative to the gantry, enabling dynamic adjustment of the vision device's tilt angle while maintaining a consistent stow position through the selectable stow position sub-assembly with multiple detent positions
Solution Approach 2:
The mount system is divided into distinct functional modules: a gantry attached to the helmet, a carriage that moves along the gantry, and a selectable stow position sub-assembly with shaped apertures and fasteners. This segmentation allows each component to perform its specific function independently while contributing to overall stow position consistency
2Adaptability or versatility
If a single-size mount is used, then the device complexity is reduced, but it cannot accommodate different helmet sizes and shapes
Solution Approach 1:
The mount system employs a universal interface design with the selectable stow position sub-assembly that can accommodate multiple helmet sizes and shapes through adjustable positioning. The shaped aperture and fastener mechanism provides multiple selectable stow positions that can be configured for different user requirements and helmet configurations, making the system versatile across various helmet types
3Strength
If a rigid fixed-position mount is used, then positional stability is achieved, but it cannot accommodate heavier vision devices like fused panoramic goggles
Solution Approach 1:
The mount system incorporates adjustable positioning mechanisms including a tilt adjustment assembly and a selectable stow position sub-assembly with multiple detent positions. These dynamic adjustment capabilities allow the system to be optimized for different vision device weights and configurations, providing both strength for heavy devices and ease of operation through selectable positions
4Adaptability or versatility
If multiple selectable stow positions are added, then adaptability to different configurations is improved, but the device complexity increases
Solution Approach 1:
The selectable stow position mechanism is segmented into distinct components: a shaped aperture provided in one or both of the gantry and carriage, and a fastener that can be positioned in different locations within the aperture. This segmentation simplifies the overall mechanism while providing multiple selectable stow positions through the relative positioning of these components

AI summary
Mounting systems configured to mount vision systems such as goggles to target devices such as helmets include a gantry and carriage assembly having a hinge assembly with a pill and a tilt adjustment assembly that cooperates with the pill to move the carriage between various tilt positions and between a deploy and a stow position that is agnostic of deployed tilt setting. The tilt adjustment assembly includes a tilt member that moves in a front to back direction. The gantry and carriage assembly also includes a bore in an upper portion of the carriage and a stow insert that also cooperates with the pill to lock the pill into a stow detent and secure the gantry and carriage assembly in the stow position.
