Helmet Display Lateral Movement for Unobstructed Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing helmets with video acquisition devices and displays obstruct the user's view, causing eye fatigue due to alternating focus distances between the real scene and the displayed image, as one eye is covered while the other views the display.
Innovation Solution
A helmet design with a display that can be moved laterally and angled, allowing unhindered viewing by providing means for the display to be adjusted from a fully frontal position to a position where it is moved laterally and rotated upwardly, using a C-shaped guide and blocking mechanism to maintain focus on a single distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the display is arranged frontally in front of the user's eyes, then the user can view displayed images, but the user's view of the real scene is obstructed
Solution Approach 1:
The display is made movable along a guide mechanism, allowing it to dynamically change position between a frontal viewing position and a retracted position. This dynamic adjustment enables the display to be brought forward when image viewing is needed and retracted when unobstructed real scene viewing is required, resolving the contradiction between providing display access and maintaining clear viewing of the real environment.
2Loss of information
If one eye is covered by the display to view images, then the display can be seen, but the ocular muscles are intensely strained due to alternating focus distances
Solution Approach 1:
The movable display allows both eyes to remain uncovered and maintain the same focus distance on the real scene while the display is retracted. When the display is brought forward, it can be positioned to allow both eyes to view images without intense alternating focusing, as the display movement enables a stable viewing configuration rather than forcing one eye to cover and the other to focus at different distances.
3Device complexity
If the display is fixed in a frontal position, then the structure is simple, but the user cannot simultaneously view the real scene and displayed images with both eyes unhindered
Solution Approach 1:
A guide mechanism with minimal mechanical complexity enables the display to move between frontal and retracted positions. This simple dynamic structure provides multiple viewing configurations: the display can be retracted for unobstructed real scene viewing with both eyes, brought forward for image viewing, or positioned to allow simultaneous viewing of both real scene and display, thus achieving high adaptability with relatively simple structural additions.

AI summary
A helmet with video acquisition device and display, comprising a helmet shell on which at least one video acquisition device is fixed, and a display arranged at one end of a front piece of the helmet; further comprising elements to allow the movement of the display laterally with respect to the active position in which the display is arranged completely in front of the eyes of a user.
