Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems for aviation require complex integration with aircraft instrumentation, necessitating installation expertise and increasing costs, while also lacking user-friendly, visually sensible navigation aids for pilots.
Innovation Solution
A personal aviation navigation system comprising a head-mounted orientation sensor, a portable coordinate position sensor, and a processor that provides visually sensible outputs on a partially transparent display, overlaying navigation information onto the pilot's view without requiring interface with aircraft instrumentation, using a commercially available inertial sensor and GPS receiver, and offering features like landing strip designation, approaching aircraft warnings, and temporary flight restriction zone indications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current navigation systems are integrated with aircraft instrumentation, then navigation functionality is achieved, but device complexity and installation difficulty increase
Solution Approach 1:
The patent extracts the navigation system from the aircraft instrumentation ecosystem and makes it fully portable. The system uses standalone GPS receivers, inertial measurement units, and head-mounted displays that operate independently of aircraft systems, eliminating the need for complex integration while maintaining navigation functionality
Solution Approach 2:
The patent creates a universal navigation system that can operate with any aircraft type without requiring type-specific integration. The head-mounted display and portable processors work across different aircraft platforms, making the system adaptable to various aviation applications without increasing complexity
2Reliability
If current navigation systems are integrated with aircraft instrumentation, then navigation functionality is achieved, but installation cost increases
Solution Approach 1:
By extracting the navigation system from aircraft-specific instrumentation and using commercially available portable components (GPS receivers, inertial sensors, off-the-shelf displays), the patent dramatically reduces installation costs while maintaining full navigation functionality
Solution Approach 2:
The patent employs inexpensive, commercially available components that can be easily replaced if needed. The portable processors, GPS receivers, and head-mounted displays use standard consumer electronics that are much cheaper than specialized aviation instrumentation, reducing overall system cost
3Loss of information
If traditional navigation displays are used, then navigation information is provided, but user-friendliness and visual sensibility decrease
Solution Approach 1:
The patent transitions from traditional two-dimensional panel displays to three-dimensional head-mounted displays that overlay navigation information directly on the pilot's field of view. This dimensional change makes the information more intuitive and easier to process by presenting it in the natural spatial context of flight
Solution Approach 2:
The patent introduces an intermediary layer between the navigation system and the pilot through head-mounted displays that present information in a visually sensible format. This intermediary translates complex navigation data into intuitive visual cues that are easily understood and acted upon by the pilot
