Aircraft Safety Management System with Authentication Switch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional safety management systems for flying objects do not effectively prevent unauthorized use, accidents, and collisions, as they fail to inhibit dangerous operations by owners and lack practical means for configuring flight enable/disable states in existing flying objects.
Innovation Solution
A safety management system that includes an authentication information storage unit, operator authentication means, and a safety management device with switching means to control the electrical connection between the motor controller and power source, allowing for easy flight enable/disable states and preventing unauthorized use by physically limiting power supply, while enabling route authentication and flight history recording.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional authentication systems are used to control flight enabled/disabled state, then unauthorized use can be prevented, but dangerous operations by authorized operators cannot be prevented
Solution Approach 1:
The patent divides the safety management system into multiple independent authentication units: operator authentication means, route authentication means, and area authentication means. Each unit independently verifies different aspects of flight authorization, creating layered safety checks that prevent both unauthorized use and dangerous operations by segmented verification points throughout the system
Solution Approach 2:
The system performs multiple authentication checks before flight is permitted: operator authentication is performed first, then route authentication, and finally area authentication. This preliminary action sequence ensures all safety conditions are verified before the flying object can operate, preventing dangerous operations in advance rather than reacting to them
2Adaptability or versatility
If flight control is implemented through main control unit software, then flexibility is achieved, but practical deployment to existing flying objects is difficult
Solution Approach 1:
The patent introduces a separate safety management device as an intermediary component between the existing main control unit and the flight control system. This mediator handles all authentication and safety decisions independently, while the main control unit continues its normal operations. This intermediary approach allows deployment to existing flying objects without modifying their core control software, achieving both flexibility and ease of manufacture
Solution Approach 2:
The safety management device is designed as a universal component that can be integrated with various types of flying objects regardless of their specific control systems. It performs multiple functions including operator authentication, route authentication, area authentication, and flight control, making it adaptable to different applications while maintaining a standardized implementation that simplifies deployment
3Reliability
If physical power supply control is used to disable flight, then unauthorized operation is prevented, but control flexibility is reduced
Solution Approach 1:
The switching means is designed to dynamically control power supply based on authentication results and flight conditions. It can switch between different power supply states (enabled, disabled, limited) depending on whether the operator is authorized, whether the route is approved, and whether the current area permits flight. This dynamic control maintains high reliability through physical security while preserving operational flexibility through conditional power management
Data Source
AI summary
A safety management system to prevent unauthorized use, accident, resale, theft, and so forth of a flying object. The safety management system includes changing, at a motor controller, a power feeding amount to each drive unit based on an instruction from a main control unit, an authentication information storage unit which records registered identification information for performing operator authentication, an authentication accepting unit which accepts an input of input identification information, an operator authentication unit which performs operator authentication of an operator of the flying object based on the input identification information and the registered identification information, and a safety managing unit connected between a power source of the flying object and the motor controller of the flying object. The safety managing unit includes a switch which controls electrical connection between the motor controller and the power source based on the result of the operator authentication.
