Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unmanned aerial vehicle (UAV) swarms face limitations in detecting incidents and recovering due to restrictions on transmitting distance, low battery life, and inefficient swarming algorithms, leading to potential task failures.
Innovation Solution
Implementing a method for UAV user equipment (UE) replacement within a UAV swarm, where a backup UAV UE is configured and activated to replace a UE that cannot perform normal operations, using dedicated RRC signaling or system information blocks to transmit configuration and replacement commands, and establishing a sidelink connection to ensure seamless replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a self-organized UAV swarm is used, then the device complexity is reduced and ease of operation is improved, but the reliability deteriorates due to limited incident detection and recovery capability
Solution Approach 1:
The patent applies preliminary action by pre-configuring backup UAV UEs with necessary communication parameters and establishing standby relationships before incidents occur. When a primary UAV UE fails, the pre-configured backup can immediately take over without requiring complex real-time reorganization, thus maintaining reliability while preserving the simplicity of autonomous operation.
Solution Approach 2:
The patent introduces a base station as an intermediary that facilitates the replacement process by transmitting replacement commands and configuration information. This intermediary enables reliable incident detection and recovery by coordinating the transition from primary to backup UAV UE, while the swarm itself maintains its simple self-organized structure.
2Use of energy by moving object
If transmission distance is restricted to maintain energy efficiency, then use of energy is improved, but reliability deteriorates due to limited coordination capability for incident detection
Solution Approach 1:
The patent applies local quality by enabling UAV UEs to operate with different transmission power levels based on their roles. Primary UAV UEs performing tasks use restricted transmission distances for energy efficiency, while backup UAV UEs and those involved in replacement coordination can utilize higher transmission powers when needed, thus maintaining both energy efficiency and reliable incident detection.
3Weight of moving object
If battery life is limited to reduce weight, then the weight of moving object is improved, but reliability deteriorates due to low battery life affecting operation duration
Solution Approach 1:
The patent applies copying by creating backup copies of UAV UEs with identical configurations and capabilities. These backup UAV UEs serve as replacements when primary UAVs fail or deplete their battery, thus extending the overall operation duration of the swarm without requiring individual UAVs to carry excessive battery weight.
4Device complexity
If inefficient swarming algorithms are used to reduce device complexity, then device complexity is improved, but productivity deteriorates due to slow incident response and recovery
Solution Approach 1:
The patent applies preliminary action by pre-establishing backup relationships and configuring replacement parameters before incidents occur. This eliminates the need for complex real-time decision-making algorithms during incident response, as the replacement process follows pre-determined rules, thus maintaining low algorithmic complexity while improving productivity through faster incident recovery.
