Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current UAV systems fail to meet safety requirements, leading to increased safety incidents due to inadequate verification of flight suitability and timely application of airworthiness and safety updates, resulting in unsafe operations.
Innovation Solution
An online verification method and system that performs flight suitability verification on UAV systems, including firmware, ground station configurations, and safety databases, determining handling measures such as upgrades or flight restrictions based on verification results to ensure safe operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flight suitability verification is performed on UAV systems, then safety level is improved, but device complexity increases
Solution Approach 1:
The verification system is divided into multiple independent verification modules, each responsible for specific verification items such as firmware version verification, configuration parameter verification, and safety database verification. This segmentation allows the complex verification process to be broken down into manageable, independent components that can be executed separately and systematically.
Solution Approach 2:
A ground station serves as an intermediary between the UAV and the verification system. The ground station receives verification requests from the UAV, performs the verification operations, and returns results to the UAV. This intermediary structure simplifies the overall system architecture by centralizing the verification logic in a dedicated component rather than distributing it across all system elements.
2Measurement precision
If multiple verification items are checked, then measurement precision is improved, but verification time increases
Solution Approach 1:
The system performs preliminary checks on verification items before executing the complete verification process. By pre-assessing which verification items are most critical or likely to fail, the system can prioritize these items and potentially skip less critical checks if time constraints arise, thus maintaining high verification accuracy while reducing overall verification time when necessary.
Solution Approach 2:
The verification system implements a multi-level verification approach where essential verification items are always checked, while additional verification items can be selectively performed based on flight conditions, UAV type, and risk assessment. This partial action approach ensures that critical safety requirements are always verified while allowing flexibility to reduce verification scope when appropriate, balancing accuracy and time consumption.
