Helmet Mount Apparatus for Viewing Device Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing helmet mount systems lack efficient mechanisms for adjusting the position of viewing devices like VR or AR displays between a viewable and stowed position, compromising user convenience and operational efficiency.
Innovation Solution
A helmet mount apparatus featuring a track assembly with a main carriage and vertical adjustment assembly, along with an axial sliding assembly, allows for adjustable positioning of viewing devices via a gear rack and slide lock mechanism, enabling easy transition between deployed and stowed positions, and customizable stopping points through interchangeable detent plates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed helmet mount system is used, then the viewing device remains stable and secure, but the user cannot adjust the position between viewable and stowed positions
Solution Approach 1:
The mount system transitions from a fixed structure to a dynamic adjustable system using a sliding carriage assembly that moves along a track assembly. The carriage can be positioned at different locations along the track and locked in place using a slide lock mechanism, enabling the viewing device to transition between viewable and stowed positions while maintaining stability when locked.
Solution Approach 2:
The mount system is divided into separate functional components: a track assembly attached to the helmet, a sliding carriage assembly that holds the viewing device, and a slide lock mechanism. This segmentation allows each component to perform its specific function independently while working together to provide adjustable positioning.
2Ease of operation
If the viewing device is always in the viewable position, then the user can access the display easily, but the user experiences neck strain from prolonged viewing
Solution Approach 1:
The ability to dynamically reposition the viewing device along the track allows the user to switch between having the device in front of the face (viewable position) and stowed behind the helmet. This dynamic positioning eliminates the need to maintain a fixed viewing posture, thereby reducing neck strain while preserving easy viewing accessibility when needed.
3Ease of operation
If a simple mount without locking mechanism is used, then the device is easy to operate, but the viewing device cannot maintain stable stopping positions
Solution Approach 1:
The slide lock mechanism automatically engages with the track teeth when the carriage is positioned, providing self-locking capability. The user simply needs to press the release button to move the carriage, and the lock engages automatically at the desired position, maintaining both ease of operation and position stability without requiring manual locking actions.
Solution Approach 2:
The slide lock mechanism acts as an intermediary between the user's manual positioning action and the carriage's final stable position. The lock engages with specific teeth on the track to hold the carriage at predetermined positions, providing reliable stopping points while maintaining ease of adjustment through the release button mechanism.
4Object-affected harmful factors
If the viewing device is stowed continuously, then neck strain is reduced, but the user cannot quickly access the display when needed
Solution Approach 1:
The dynamic positioning system allows rapid transition between stowed and viewable positions. The viewing device can be quickly deployed by pressing the release button and sliding the carriage along the track to the front position, then locking it in place. This enables fast switching between the protective stowed position and the accessible viewable position.

AI summary
A helmet mount apparatus for adjusting the position of a viewing device on a helmet includes a track assembly removably attachable to the helmet and a main carriage assembly slidably attached to and movable along the track assembly. A vertical adjustment assembly is pivotally coupled to the main carriage assembly and an axial sliding assembly is coupled to the vertical adjustment assembly, wherein the vertical adjustment subassembly is configured to detachably couple to the viewing device.
