Modular Helmet Display System With Mechanical Arch And Binoculars
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing helmet-mounted display systems for aircraft pilots are complex to switch between daytime and nighttime modes due to the need for temporary storage of multiple modules, and the lateral tilt of the display device limits the available field of view when using binoculars.
Innovation Solution
A modular helmet-mounted display system with a standardized helmet shell and adaptable attachment members for binoculars and display devices, featuring a mechanical arch with adjustable attachment points, a movable visor, and a flat pupil-expansion optical combiner to allow simultaneous mounting of display and binoculars, along with a posture detection device for precise adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a modular system with separate visor and binoculars modules is used, then adaptability to different missions is improved, but device complexity and storage requirements increase
Solution Approach 1:
The patent combines the visor and display device into a single integrated module that can be mounted on the helmet. This integration eliminates the need for separate storage locations for different modules, as the combined module serves multiple functions (day vision, night vision, display) when mounted together with the binoculars. The mechanical arch provides a unified mounting structure that accommodates all components in a single configuration.
Solution Approach 2:
The integrated visor-display module is designed to perform multiple functions: it serves as a protective visor during day, incorporates a display device for synthetic image presentation, and can work with night-vision binoculars. This multi-functionality reduces the number of separate components needed and eliminates the complexity of switching between different module configurations.
2Ease of operation
If the display device is laterally tilted to accommodate binoculars, then ease of mounting is improved, but the available field of view is reduced
Solution Approach 1:
The patent employs adjustable mounting mechanisms on the mechanical arch that allow the display device and binoculars to be positioned at optimal angles. The display device can be adjusted in position and orientation to work harmoniously with the binoculars, enabling full utilization of the field of view while maintaining ease of mounting. The posture detection device enables dynamic adjustment to compensate for user morphology differences.
Solution Approach 2:
The mounting system allows for adjustment of angular and positional parameters of both the display device and binoculars. By changing these parameters, the system optimizes the field of view and ensures proper alignment between the display and binoculars, eliminating the need for fixed lateral tilting that would reduce the available field.
3Ease of manufacture
If a standardized helmet structure is used, then ease of manufacture is improved, but adaptability to different user morphologies decreases
Solution Approach 1:
The patent incorporates adjustable and repositionable mounting devices on the standardized mechanical arch. These adjustable components allow the display device and binoculars to be repositioned to accommodate different user morphologies. The posture detection device works with adjustment mechanisms to dynamically adapt the system to individual user requirements while maintaining a standardized base structure.
Solution Approach 2:
The system is divided into a standardized helmet structure with a mechanical arch, and separate adjustable mounting components for the display device and binoculars. This segmentation allows the standardized arch to be manufactured efficiently while the adjustable components provide adaptability to different user morphologies. The attachment members can be repositioned along the arch to fit different users.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables seamless switching between modes without complex assembly, maintains a clear field of view, and accommodates morphological differences, ensuring harmonization and efficient use of the display system across various configurations.
Implementation Method 1
a projection optic and an optical combiner or mixer. The combiner may be integrated into the helmet's visor... It is then an optical plate made up of a plurality of prisms reflecting the light of the synthetic image toward the eye
Implementation Method 2
Night-vision binoculars capture the luminosity of objects in the near-infrared and render an image visible using light-intensification devices

AI summary
A modular helmet display system includes at least one helmet shell, binoculars and a display device. The helmet shell includes a mechanical arch fixedly mounted on the front part of the helmet, and the mechanical arch includes at least one first device for attaching the binoculars. In the system, the mechanical arch includes a second device for attaching the display device. The display device may include a posture detection device and an adjustment mechanism. The display system may include a mechanical cover which is mounted in place of the display device, the shape of the cover being adapted so as to hide the upper part of the helmet. A mobile visor can be mounted on the mechanical arch.
