Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current unmanned aerial vehicles (UAVs) face limitations in mission duration and flexibility due to battery power constraints and the need for tethered systems, which restrict their operational range and adaptability.
Innovation Solution
A modular aerial vehicle system that can switch between battery-powered and tethered configurations, using a spooling apparatus with a stationary spool and motor to manage tether tension, allowing for extended flight times and adaptable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If UAVs use battery power, then they have operational flexibility and unrestricted movement, but mission duration is limited by battery life
Solution Approach 1:
The system dynamically switches between battery-powered and tethered configurations based on operational needs. The aerial vehicle can transition from autonomous battery operation to tethered power supply, allowing mission duration to be extended while maintaining operational flexibility through configurable power sources.
2Duration of action of moving object
If UAVs use tethered power supply, then mission duration is extended, but operational range and flexibility are restricted
Solution Approach 1:
The system employs dynamic configuration where the tether can be deployed or retracted based on operational requirements. When extended range is needed, the tether is retracted or disconnected, allowing battery-powered autonomous operation. When extended duration is prioritized, the tether is deployed for continuous power supply.
3Reliability
If a spooling apparatus with motor is used to manage tether tension, then tether tension is optimized, but device complexity increases
Solution Approach 1:
The spooling apparatus uses a motor that can be controlled to automatically maintain optimal tether tension during deployment and retrieval. The system self-regulates the tether management based on operational conditions, reducing the need for complex mechanical tensioning mechanisms while ensuring reliable tether control.
