Helmet-Mounted Display Module With Removable Binocular Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surveillance operators face significant fatigue and reduced situational awareness due to frequent switching between different vision equipment (binoculars and display devices) for varying environmental conditions and brightness, necessitating multiple equipment changes that disrupt monitoring and increase clutter.
Innovation Solution
A removable visualization system with interchangeable attachments for both binoculars and display devices, compatible with helmets and headbands, allowing seamless transitions without the need for constant equipment swaps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If operators use separate equipment for daytime surveillance (headband with display device) and nighttime surveillance (helmet with binoculars), then each equipment can be optimized for its specific function, but operators must frequently switch between equipment which causes fatigue and reduces situational awareness
Solution Approach 1:
The patent combines the display device and binoculars into a single integrated assembly that can be mounted on a single cranial support. The display device (6) and binoculars (7) are positioned adjacent to each other with the display device located between the operator's eye and the binoculars, allowing both functions to be performed simultaneously without switching equipment.
Solution Approach 2:
The integrated assembly can be mounted on different types of cranial supports (headband or helmet) depending on the operational requirements. The removable mounting interface allows the same assembly to be universally attached to either a headband for daytime use or a helmet for nighttime use, providing multi-functionality across different surveillance conditions.
2Reliability
If operators use a heavy protective helmet for nighttime surveillance with binoculars, then night vision capability is enabled, but the helmet weight increases and requires replacing lighter daytime headband equipment
Solution Approach 1:
The system separates the optical functions (display device and binoculars) from the cranial support structure. The binoculars and display device are mounted on the cranial support rather than being integrated into it, allowing operators to use lighter headbands during daytime and only add helmet protection when nighttime surveillance is required, rather than wearing heavy helmets continuously.
3Illumination intensity
If operators frequently switch between display devices and binoculars to adapt to varying brightness and terrain conditions, then optimal viewing is maintained, but time is lost during transitions and operator fatigue increases
Solution Approach 1:
The display device and binoculars are integrated into a single assembly that can be worn simultaneously, eliminating the need to switch between separate equipment. The display device is positioned to allow the operator to view both the external environment through the binoculars and the superimposed information from the display device without removing either component.
4Adaptability or versatility
If multiple separate equipment sets are maintained for different surveillance conditions, then each equipment can be optimized for its specific purpose, but equipment clutter increases at the operator station
Solution Approach 1:
The integrated assembly serves multiple functions: it provides both display device output and binocular viewing capability in a single unit. The removable mounting interface allows the same assembly to be attached to different cranial supports (headband or helmet) depending on whether daytime or nighttime surveillance is required, reducing the need for multiple specialized equipment sets.
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
Enhances situational awareness by reducing fatigue and equipment clutter, enabling operators to maintain continuous monitoring with adaptable and efficient use of binoculars and display devices.
Implementation Method 1
The combiner is then an optical plate made up of a plurality of prisms that reflect the light from the synthetic image towards the eye
Implementation Method 2
The projection lens ensures the collimation of the image displayed in the combiner
Implementation Method 3
Night vision binoculars capture the light from objects in the near-infrared spectrum and produce a visible image using image intensifiers
