Air Mobility Bird Avoidance Using Forward Lattice Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for preventing air mobility collisions with birds during flight are inefficient due to the complexity and cost of satellite navigation and observation systems, which struggle to detect birds in time for effective avoidance.
Innovation Solution
A system and method utilizing an image formation device on the air mobility to project a lattice-patterned image in front of the vehicle, controlled by a sensor and controller to adjust image position and size based on flying speed, ensuring birds can perceive and avoid the image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If satellite navigation and observation satellites are used to detect birds, then bird detection capability is improved, but system complexity and cost increase significantly
Solution Approach 1:
The patent extracts the bird detection function from complex satellite navigation systems and implements it using a simple image formation device (hologram projector) mounted on the air mobility itself. This eliminates the need for expensive satellite infrastructure while achieving the same bird warning function through projected lattice images that birds can perceive and avoid.
Solution Approach 2:
The patent creates a virtual lattice pattern image (hologram) that appears in front of the air mobility to warn birds. This copied visual representation serves as a substitute for direct bird detection, allowing birds to perceive the air mobility's presence and alter their flight path without requiring actual bird detection capabilities.
2Area of stationary object
If satellite observation systems are deployed, then bird detection coverage is improved, but cost and infrastructure requirements increase
Solution Approach 1:
The air mobility performs its own bird warning function by projecting lattice images from an onboard image formation device. This self-service approach eliminates the need for external satellite infrastructure, reducing both the quantity of equipment needed and the associated costs while maintaining effective bird detection and warning coverage.
3Reliability
If the image formation device projects a lattice image, then bird avoidance effectiveness is improved, but energy consumption increases
Solution Approach 1:
The image formation device operates periodically or on-demand based on flight conditions rather than continuously. The controller activates the lattice image projection when birds are detected or during critical flight phases, reducing energy consumption while maintaining collision prevention reliability when needed.
Solution Approach 2:
The lattice image parameters (position, size, pattern) are dynamically adjusted based on the air mobility's flying speed and distance from obstacles. This dynamic adaptation optimizes energy consumption by projecting images only at necessary intensities and durations while maintaining effective bird avoidance.
