Rotatable Helmet Visor Mount Arms for Bulk Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional helmet-mounted visors are bulky, inconsistent in fit across different helmets, and require removal of existing mounts, which hampers their utility and stability.
Innovation Solution
A helmet-mounted visor with rotatable mount arms that attach to a helmet via a rail system, allowing the lens to be positioned in multiple configurations (use, middle, and stowage positions) using a locking mechanism, enabling easy adjustment and maintaining mount utility on the helmet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional helmet-mounted visors are used, then ballistic protection is provided, but the visors are bulky and require removal of existing mounts
Solution Approach 1:
The mount arm is divided into multiple segments (first portion and second portion) that can rotate relative to each other, allowing the visor to be positioned in different configurations (use position, stowage position, intermediate positions) without requiring a completely different mounting system
2Reliability
If traditional helmet-mounted visors are used, then ballistic protection is provided, but the visors are inconsistent in fit across different helmets
Solution Approach 1:
The mount arm design with rotatable portions and locking mechanisms provides a universal mounting solution that can adapt to different helmet types and configurations, allowing consistent fit and ballistic protection across various helmets while maintaining the ability to mount and dismount the visor as needed
3Reliability
If traditional helmet-mounted visors are used, then ballistic protection is provided, but the mounts must be removed which hampers utility
Solution Approach 1:
The locking mechanism allows the mount arm to transition between locked and unlocked states, enabling the visor to be securely mounted when needed and easily removed when not needed, providing dynamic adaptability rather than a fixed mounting solution
4Adaptability or versatility
If a rotatable mount arm with locking mechanism is used, then the lens can be positioned in multiple configurations, but the device complexity increases
Solution Approach 1:
The locking mechanism is designed as a separate, extractable component that can be independently engaged or disengaged, allowing the basic rotatable mount structure to remain simple while adding positioning flexibility through an optional locking feature rather than complicating the entire mount structure

AI summary
A helmet mounted visor includes a lens that may be configured to extend across substantially all of a user's face. The helmet mounted visor may include a pair of mount arms coupled to the lens and each configured to releasably mount to a mount attached to a helmet. The pair of mount arms may each including first, second and third portions. The first portion may be rotatably coupled to the second portion about a first axis. The first portion may be rotatably coupled to the third portion about a second axis. The second axis may be generally perpendicular to the first axis. A locking mechanism may be provided and configured to selectively retain the first portion relative to the second portion in and between a use position where the lens is positioned in front of the user's face and a stowage position where the lens is positioned proximate the top of the helmet.
