Problem
Unmanned aerial vehicles (UAVs) face limitations in maintaining prolonged airborne operations due to battery life constraints, necessitating a solution for continuous power supply while allowing for unrestricted flight.
Innovation Solution
A surveillance drone system that includes a UAV connected to a base power station via a tether, allowing for detachable power transmission and data communication, enabling the UAV to fly unrestricted and maintain extended airborne operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a tether is connected to the UAV to provide continuous power, then the duration of airborne operation is extended, but the UAV loses freedom of movement and cannot fly unrestricted
Solution Approach 1:
The power supply system is segmented into a fixed base power station and a detachable tether assembly. The tether can be connected when prolonged power is needed and detached when flight freedom is required, allowing the system to adapt between these two states. The plug at the tether end enables clean separation of the power supply component from the mobile UAV.
Solution Approach 2:
The tether connection system transitions from a static permanent connection to a dynamic detachable connection. The plug and socket interface allows the tether to be connected or disconnected based on operational requirements, making the system adaptable rather than fixed. This dynamic capability resolves the contradiction between needing continuous power and maintaining flight freedom.
2Reliability
If a permanent harness connection is used, then power transmission is reliable, but the system cannot be controllably detached when airborne
Solution Approach 1:
The permanent harness is replaced with a segmented tether assembly featuring a plug at the end. This segmentation allows the connection to be reliably made when needed while enabling clean separation when detachment is required. The plug interface provides both reliable power transmission during connection and easy detachment when airborne.
Solution Approach 2:
The plug acts as an intermediary component between the tether and the UAV power interface. It provides a reliable electrical connection when mated, while also serving as the mechanism for controlled detachment. The plug mediates between the need for reliable power transmission and the need for operational flexibility.

Function Achieved in This Case
The system allows for prolonged UAV operation, enabling continuous monitoring and investigation of anomalies without the constraint of battery life, while also allowing for safe and controlled detachment from the power source.
Implementation Method 1
a tether for connecting the UAV to the base power station to provide electrical power to the UAV when airborne
Implementation Method 2
A plug or power module is provided at the free end of the tether configured to be detachably coupled with the UAV, to transmit electrical power to, and, possibly, data to and from, the UAV

AI summary
A surveillance drone system is provided herein generally including an UAV, a base power station, and, a tether for connecting the UAV to the base power station to provide electrical power to the UAV when airborne. The base power station may include a cable take-up assembly for releasing and taking up the tether. A plug or power module is provided at the free end of the tether configured to be detachably coupled with the UAV, to transmit electrical power to, and, possibly, data to and from, the UAV. With the plug or power module being detached, the UAV is free to fly unrestricted. This arrangement allows for the UAV to be airborne for prolonged periods to allow for monitoring a region and for release to allow the UAV to investigate anomalies in the monitored region.
