UAV Dock Unlock and Ascent Control During Sudden Vehicle Acceleration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging systems for unmanned air vehicles (UAVs) face challenges in properly controlling takeoff and landing during sudden acceleration events, such as braking or collisions, which can disrupt the UAV's flight position and imaging capabilities.
Innovation Solution
The proposed imaging system includes a UAV equipped with a flight controller, imaging unit, communication controller, and acceleration detector. When an acceleration threshold is exceeded, the system unlocks the UAV from its dock in the opposite direction of the acceleration, allowing the UAV to ascend and capture images from a proper flight position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the unmanned air vehicle is locked to the movable object, then the UAV can be securely positioned, but the UAV cannot take off during sudden acceleration events
Solution Approach 1:
The locking mechanism transitions from a static locked state to a dynamic unlocked state based on acceleration conditions. The acceleration detector monitors real-time acceleration, and when threshold values are exceeded, the locking mechanism automatically unlocks, allowing the UAV to take off. This dynamic response enables the system to adapt between secure positioning and takeoff capability based on operational conditions.
2Stability of the object's composition
If the UAV maintains constant distance from the movable object, then positioning is stable, but the UAV cannot image from desired positions during movement
Solution Approach 1:
The system dynamically adjusts the UAV's positioning mode based on acceleration detection. During normal operation, the UAV maintains constant distance for stable positioning. When acceleration exceeds thresholds, the system transitions to takeoff mode, allowing the UAV to ascend and image from elevated positions, thus achieving both stability and flexibility.
3Adaptability or versatility
If the UAV is unlocked during acceleration, then the UAV can take off, but the UAV may be damaged by the acceleration force
Solution Approach 1:
The acceleration detector continuously monitors acceleration levels before they reach damaging thresholds. When predetermined threshold values are detected, the locking mechanism proactively unlocks the UAV, allowing it to take off and escape the harmful acceleration zone before damage can occur. This preliminary action prevents the harmful effect of excessive acceleration on the UAV structure.

AI summary
When an acceleration equal to or larger than a threshold value is exerted to a vehicle, an unmanned air vehicle takeoff and landing dock unlocks an unmanned air vehicle in a direction opposite to a direction in which the acceleration is exerted. When an acceleration detector of the unmanned air vehicle detects the acceleration equal to or larger than a threshold value, a flight controller of the unmanned air vehicle controls flight of the unmanned air vehicle to cause the unmanned air vehicle to ascend. Further, the unmanned air vehicle starts imaging by an imaging unit and starts transmitting imaging data acquired.
