Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need to prevent collisions between hover aircraft and obstacles during maneuvers, such as takeoff, landing, or rescue operations, due to judgment errors or communication errors between operators and pilots.
Innovation Solution
The solution involves an aircraft equipped with sensors having a plane sweep region to measure distances between obstacles and the aircraft, a control unit generating alarm signals when safety thresholds are breached, and a graphic interface displaying critical information for safe maneuvering, including recommended backoff directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an operator visually monitors distance to obstacles during hover maneuvers, then the aircraft can be operated close to obstacles, but collision risk increases due to human judgment or communication errors
Solution Approach 1:
The patent introduces an automatic obstacle detection and alarm system as an intermediary between the operator and the aircraft control. Sensors detect obstacle positions and distances, the control unit processes this data, and the system automatically generates alarm signals when safety thresholds are breached, removing the need for human judgment in distance assessment and eliminating communication errors between operator and pilot
Solution Approach 2:
The aircraft equip s itself with autonomous safety monitoring capabilities through integrated sensors, control units, and alarm systems that automatically detect obstacles, calculate distances, and trigger warnings without requiring external human intervention or communication, making the system self-protecting against collision risks
2Measurement precision
If sensors are positioned to surround the drive shaft, then complete 360-degree obstacle detection is achieved, but device complexity increases
Solution Approach 1:
The patent combines multiple sensors into a single integrated sensor unit that surrounds the drive shaft, merging their functions into one cohesive component that provides complete 360-degree detection coverage without requiring separate sensor assemblies positioned at different locations
Solution Approach 2:
The sensor unit positioned around the drive shaft serves multiple functions simultaneously: it provides omnidirectional obstacle detection, measures distances to obstacles from multiple angles, and integrates with the existing drive shaft structure, eliminating the need for separate mounting structures and reducing overall system complexity
