Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pairing methods for unmanned aerial vehicles (UAVs) are prone to mis-pairing when multiple sets are paired simultaneously, leading to instability and inflexibility in communication channels.
Innovation Solution

Engineering Contradiction Analysis
1Ease of operation
If a fixed channel pairing mode is used, then the pairing process is simple, but mis-pairing occurs when multiple sets of unmanned aerial vehicles are paired simultaneously
Solution Approach 1:
The patent applies dynamics by transitioning from a fixed channel pairing mode to a dynamic channel selection mechanism. The system automatically selects pairing channels from multiple available channels based on real-time conditions, allowing the pairing process to adapt to different scenarios. This dynamic approach prevents mis-pairing when multiple UAV sets are paired simultaneously while maintaining operational simplicity through automated channel selection.
Solution Approach 2:
The patent introduces an intermediary mechanism through the use of a pairing channel selection module that mediates between the remote controller and the unmanned aerial vehicle. This intermediary component manages the pairing process by coordinating channel selection and avoiding direct conflicts between multiple pairing operations, thereby preventing mis-pairing while keeping the overall process simple.
2Reliability
If multiple channels are used for pairing, then pairing stability is improved, but the complexity of the pairing process increases
Solution Approach 1:
The patent applies self-service by implementing an automated channel selection mechanism that operates without requiring manual intervention. The system automatically evaluates available channels and selects the most appropriate pairing channel based on predefined criteria, thereby achieving stable pairing across multiple channels while avoiding the complexity of manual channel configuration and selection.
Solution Approach 2:
The patent utilizes parameter changes by dynamically adjusting the pairing channel parameters based on the operational environment. The system changes channel frequencies and selection criteria according to real-time conditions, enabling stable pairing across multiple channels while maintaining a simplified process through automated parameter adjustment rather than manual configuration.
3Reliability
If a one-to-one pairing relationship is established, then the communication is secure, but the flexibility for one-to-many pairing is reduced
Solution Approach 1:
The patent applies universality by designing a pairing system that can perform multiple functions: it supports both one-to-one pairing for secure communication and one-to-many pairing for flexible control. The system uses universal pairing mechanisms that can adapt to different relationship models, allowing a single UAV to be paired with multiple remote controllers while maintaining security through controlled pairing protocols and channel management.
