Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Civilian unmanned aerial vehicles (UAVs) lack advanced flight data recording capabilities, which hinders accident reconstruction, operator performance optimization, and safety improvements, as they do not typically record in-flight data, adjust performance based on operator experience, or share flight data through social networks.
Innovation Solution
A system and method for recording and analyzing operational data from UAVs, involving sensors that collect and transmit data for real-time analysis, adjusting operating parameters based on operator profiles, and enabling data sharing, including image and video recording for accident investigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flight data recording capability is added to civilian UAVs, then accident reconstruction and safety improvement are enhanced, but device complexity increases
Solution Approach 1:
The patent combines multiple functions into a single integrated system: flight data recording, operator profile management, real-time performance adjustment, and social networking capabilities are merged into one comprehensive platform. This reduces overall system complexity while maintaining enhanced reliability and safety features.
Solution Approach 2:
The flight data recorder is designed as a multi-functional device that not only records accident data but also continuously monitors flight parameters, adjusts UAV performance based on operator experience, and enables social sharing of flight information. This universal approach maximizes the value of the added complexity.
2Reliability
If real-time data analysis and performance adjustment are implemented, then operator safety and flight experience optimization are improved, but use of energy increases
Solution Approach 1:
The system implements selective real-time analysis rather than continuous full-scale processing. It focuses computational resources on critical safety parameters and operator profile matching while reducing analysis intensity for non-critical flight data, thereby improving safety without proportionally increasing energy consumption.
Solution Approach 2:
The performance adjustment mechanism operates periodically based on significant flight events or predefined intervals rather than continuously. The system updates UAV performance characteristics at strategic moments during flight, reducing computational load and energy usage while maintaining operator safety benefits.
3Loss of information
If comprehensive flight data recording and social networking integration are added, then information sharing and operational insights are improved, but device complexity increases
Solution Approach 1:
The flight data recorder serves as a universal platform that handles both traditional recording functions and modern social networking integration. By making the core recording system multi-functional, the patent reduces the need for separate dedicated systems, thereby managing complexity while enabling comprehensive data sharing and operational insights.
