Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing unmanned aerial vehicles (UAVs) lack effective mechanisms for safe operation and package delivery, particularly in scenarios where anomalies occur during flight, leading to potential crashes and inefficiencies in navigating rail systems.
Innovation Solution
An unmanned aerial vehicle (UAV) configuration with rotary wings, a control circuit, and a movable block that adjusts the inclination of the rotary wings relative to a rail, allowing for controlled movement along the rail and safe operation by setting appropriate rotation rates and angles, enabling efficient package delivery and anomaly detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the UAV uses a rail system for guided flight, then navigation precision is improved, but the device complexity increases due to the connector and movable block mechanisms
Solution Approach 1:
The connector acts as an intermediary component that interfaces between the UAV and the rail system. It includes a movable block that can engage with the rail to provide guided movement while allowing the UAV to remain primarily aerodynamically supported. This mediator approach enables precise rail-guided navigation without requiring the entire UAV structure to be complexly integrated with the rail.
2Use of energy by moving object
If the UAV operates at lower rotation rates near the rail, then energy consumption is reduced, but the reliability decreases due to reduced lift margin
Solution Approach 1:
The system provides beforehand cushioning by having the connector engage with the rail structure before critical failures can occur. The rail connection serves as a safety net that prevents crashes even when the UAV operates at lower rotation rates with reduced lift margin. This prior cushioning mechanism allows energy-efficient operation while maintaining reliability through the physical support of the rail system.
3Ease of operation
If the movable block increases the angle of the rotary wings, then the UAV can navigate along the rail more effectively, but the stability of flight decreases
Solution Approach 1:
The control system segments the stabilization function by separating the rotary wing angle control from the overall flight stability. The movable block independently adjusts the rotary wing angles for effective rail navigation, while the connector-rail interface provides passive mechanical stability. This segmentation allows aggressive angle adjustments for navigation without compromising overall flight stability.

AI summary
An unmanned aerial vehicle that delivers a package includes a plurality of rotary wings (709a), a plurality of first motors (711), a main body (712), a connector (730), a movable block (740), and a processor (734). When the connector (730) is connected to a rail (400), the processor (734) sets a rotation rate of the plurality of first motors (711) to a rotation rate that is lower than a minimum rotation rate necessary for floating and higher than a minimum rotation rate necessary for propulsion along the rail (400). Furthermore, the processor (734) causes the movable block (740) to increase the angle formed by the normal direction of an imaginary plane containing the plurality of rotary wings (709a) relative to a support direction of the connector (730).
