UAV Delivery Destination Switching Under Unsafe Flight Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional unmanned aerial vehicle (UAV) delivery systems face difficulties in reaching destinations due to obstacles, strong winds, and other environmental factors, which can result in failed deliveries and inconvenience to recipients.
Innovation Solution
The UAV system includes a storage unit for multiple regions, a selecting unit to prioritize destinations, and a changing unit that alters the destination to a region with the next highest priority if the initial path is unsuitable for flight, using evaluation items like wind speed, obstacle detection, and battery status to determine path suitability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UAV flies to the originally selected destination, then the delivery follows the initial plan, but the flight may fail due to obstacles, strong winds, or other environmental factors
Solution Approach 1:
The patent implements dynamic destination selection by enabling the UAV to switch from a statically pre-selected destination to an alternative destination when environmental conditions (obstacles, wind, battery status) become unfavorable. The system continuously evaluates flight conditions and dynamically adjusts the destination based on real-time data, transforming a rigid delivery plan into a flexible adaptive system that prioritizes safe and reliable delivery.
2Object-affected harmful factors
If the UAV changes the destination to a region with the next highest priority, then the delivery can proceed under safer conditions, but the delivery location differs from the original recipient's choice
Solution Approach 1:
The patent applies beforehand cushioning by pre-storing multiple candidate destinations with priority rankings before the UAV departs. When the originally selected destination becomes unsafe due to environmental factors, the system can immediately switch to a pre-prepared alternative destination without requiring complex real-time calculations or user intervention. This pre-prepared buffer of alternative destinations ensures continuous safe operation while maintaining user convenience through automated decision-making.
3Reliability
If the UAV evaluates multiple evaluation items (wind speed, obstacles, battery status) before selecting a destination, then the flight safety improves, but the system complexity increases
Solution Approach 1:
The patent segments the complex destination selection process into distinct evaluation components: wind speed evaluation, obstacle detection, battery status monitoring, and priority-based destination ranking. Each evaluation item is processed independently and contributes to the overall destination selection decision. This segmentation allows the system to manage complexity by breaking down the decision-making process into manageable modules while maintaining comprehensive safety checks across all critical parameters.

AI summary
An unmanned aerial vehicle includes a storage storing information regarding a plurality of regions and a control circuitry. The control circuitry is configured to select a first one of the plurality of regions that has a highest priority among the plurality of regions as a destination, and change the destination to a second one of the plurality regions that has a next highest priority among the plurality of regions in response to determining that a selected path to the destination is not suitable for flight.
