Aircraft Head-Mounted Visualization System with Audio Headset Hasps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current head-mounted visualization systems for aeronautical applications are not compatible with audio headsets, leading to issues such as bulkiness, heat sensation, isolation, and image problems, and they lack the necessary performance and accuracy for precise information overlay on the real landscape, while also being heavy and causing visual loss due to forward slippage.
Innovation Solution
A headband-based visualization system with symmetrical lateral arches and adjustable components that allow mounting over audio headsets, incorporating a hybrid posture detection assembly with optical recognition and inertial sensors, and a thin optical plate for image superimposition, with a ball joint mechanism for flexible positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective headset is worn for head-mounted visualization, then impact protection and audio communication are provided, but the system becomes bulky, causes heat sensation, isolation, and image problems
Solution Approach 1:
The head-mounted display is divided into separate components: a lightweight spectacles frame for visual display and a separate protective headset for audio and impact protection. This segmentation allows each component to be optimized independently, reducing overall bulkiness while maintaining protection functionality.
Solution Approach 2:
The spectacles-type HMD is designed to be worn over or integrated with the protective headset, nesting the visualization function within the existing headset structure. This allows the HMD to utilize the headset's support structure without requiring a separate bulky mounting system.
2Strength
If the HMD is mounted on a headset, then the display device is supported, but it is not compatible with audio headsets and gives a sensation of heat and isolation
Solution Approach 1:
The spectacles frame is designed with universal compatibility features, allowing it to be worn with or without audio headsets. The frame structure incorporates adjustable elements that can accommodate different headset configurations, making the HMD adaptable to various wearing scenarios including over audio headsets.
3Weight of moving object
If consumer spectacles like Google Glass are used, then lightweight design is achieved, but they are not compatible with sight spectacles, audio headsets, or breathing masks
Solution Approach 1:
The spectacles frame incorporates dynamic adjustment mechanisms including adjustable temples and nose pads that can be configured to accommodate different headwear combinations. This dynamic adaptability allows the lightweight frame to work with sight spectacles, audio headsets, and breathing masks simultaneously or in various combinations.
4Measurement precision
If the visualization device is positioned in front of the eye, then accurate information overlay is achieved, but the weight causes forward slippage and visual loss
Solution Approach 1:
The spectacles frame is designed with a counterbalancing structure that distributes the weight of the visualization device across the nose bridge and temple arms. This counterweight distribution prevents forward slippage by balancing the gravitational force on the device, maintaining stable positioning for accurate information overlay.

AI summary
Visualization systems are provided which are intended to be worn by the head of a user wearing an audio headset consisting of a first hoop and two lateral earpieces, the visualization system comprising at least one headband in the form of a strap and a visualization device mounted on the headband. The headband comprises two symmetrical lateral hasps, each hasp being in the form of an arch so as to form an opening of a few centimeters between the arch and the head of the user so that, when the system is worn by the head, the opening is sufficient to allow the passage of one of the two lateral arms of the first hoop.
