Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new ultralight, single-seat aircraft that take off and land vertically poses challenges in identifying safe landing zones, especially in urban areas where traditional runway infrastructure is not available, and existing systems lack effective solutions for safety and management in these environments.
Innovation Solution
The implementation of a landing zone indicator system that includes battery-powered, portable on-the-ground indicators and vehicle-mounted indicators, using human-visible and computer vision signals to demarcate and communicate the landing zone to pilots and vehicles, ensuring safe landing and takeoff in various environments without requiring extensive infrastructure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional runway infrastructure is used for aircraft landing, then landing safety is improved, but infrastructure complexity and cost increase
Solution Approach 1:
The patent extracts the essential function of runway infrastructure (providing a defined landing zone) and implements it through portable, battery-powered indicator systems that can be deployed temporarily without permanent infrastructure. The landing zone indicators are removed from fixed infrastructure and made mobile and temporary.
Solution Approach 2:
The patent employs inexpensive, temporary landing zone indicators that can be quickly deployed and removed, replacing expensive permanent runway infrastructure for locations where runways cannot be built. These indicators are designed to be portable and temporary rather than permanent.
2Ease of operation
If portable battery-powered indicators are used, then ease of deployment is improved, but illumination intensity decreases
Solution Approach 1:
The patent combines multiple indicator units to achieve sufficient illumination intensity. Multiple portable indicators work together to define and illuminate the landing zone, compensating for the limited output of individual battery-powered units.
Solution Approach 2:
The patent employs dynamic illumination strategies where the intensity and timing of indicator activation are adjusted based on operational needs. The system can activate indicators at different intensities or sequences to maximize visibility while conserving battery power.
