Wearable Head-Mounted Display for Aircraft Piloting Assistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current piloting aid systems are inefficient in rapidly transmitting accurate information to pilots, particularly during complex flight conditions, due to lengthy processing methods and the complexity of ensuring data integrity, which can lead to delayed detection of malfunctions.
Innovation Solution
A portable display system with separate processing and display units for each eye, using dual processing means to simultaneously display piloting information on a left and right display, eliminating the need for complex cyclic redundancy checks and allowing quick pilot detection of discrepancies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex cyclic redundancy check methods are used to verify image integrity, then data accuracy is improved, but processing time increases
Solution Approach 1:
The patent divides the image data into multiple blocks and processes each block independently through separate processing means. This segmentation allows parallel processing of different image portions, significantly reducing overall processing time while maintaining data integrity through distributed cyclic redundancy checks on each block.
Solution Approach 2:
The patent performs cyclic redundancy checks on individual image blocks before final image assembly and display. By verifying data integrity at intermediate stages rather than only at the end, the system can detect and handle errors early, reducing reprocessing time and improving overall efficiency.
2Productivity
If a single processing means is used to display information, then device complexity is reduced, but the ability to rapidly transmit information to multiple pilots is limited
Solution Approach 1:
The patent employs multiple independent processing means (first processing means and second processing means) that simultaneously process different blocks of image data. Each processing unit operates independently to generate and display information on separate display means, enabling parallel information transmission to multiple pilots without requiring a single complex centralized processor.
Solution Approach 2:
Each processing means is designed to perform multiple functions: acquiring image data, performing cyclic redundancy checks, processing image blocks, and controlling display output. This multi-functionality allows the system to rapidly transmit information through multiple channels while keeping individual processing units relatively simple and modular.

AI summary
The system (10) has a display system (40) wearable on a head of a pilot and provided with a left display unit (41) to be viewed by a left eye of the pilot and a right display unit (42) to be viewed by a right eye of the pilot. A determination unit (20) includes processing units (21, 22) for processing piloting information. One of the processing units includes stored instructions for causing the information to be displayed simultaneously and respectively on the display units. The instructions determine information relative to data e.g. air speed, of an aircraft (1).
