Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for mobile communication on aircraft lack flexibility in allowing or restricting the use of mobile radio devices during flight phases, leading to unnecessary crew announcements and passenger inconvenience, as they are not automatically synchronized with flight safety.
Innovation Solution
An aircraft picocell system controlled by an aircraft control device that automatically switches on and off based on flight phases, with integrated display units to inform passengers of usage permissions, ensuring safe operation and passenger convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mobile radio devices are allowed to operate during flight phases, then passenger communication capability is improved, but interference risk to aircraft electronics increases
Solution Approach 1:
The picocell system dynamically adjusts its operational status based on real-time flight phase detection. The control device automatically switches the picocell between active and inactive states according to whether the aircraft is in safe flight phases or critical phases (take-off, landing, taxiing), thereby adapting communication availability to safety requirements without manual intervention
Solution Approach 2:
The system incorporates a feedback mechanism where the control device continuously monitors flight phase information and uses this feedback to automatically control picocell operation. The control device receives flight phase data, processes it according to safety criteria, and automatically activates or deactivates the picocell accordingly, creating a closed-loop control system that responds to changing operational conditions
2Reliability
If manual control of picocell is implemented, then safety can be maintained, but crew workload and passenger inconvenience increase
Solution Approach 1:
The picocell control system performs self-service by automatically monitoring flight phases and adjusting its own operational status without requiring crew intervention. The control device independently processes flight phase information and makes decisions about picocell activation/deactivation based on pre-programmed safety criteria, freeing the crew from manual control tasks
Solution Approach 2:
The system replaces manual mechanical control (crew members physically controlling the picocell) with an automated electronic control system. The control device uses electronic sensors to detect flight phase changes and automatically actuates the picocell switches, substituting human operation with automated electronic decision-making and control mechanisms
3Productivity
If automatic picocell control based on flight phases is implemented, then service quality is improved, but system complexity increases
Solution Approach 1:
The control device performs multiple functions within a single integrated system: it monitors flight phase parameters, processes safety criteria, controls picocell activation, and provides passenger information displays. By consolidating these diverse functions into one multi-functional control unit, the system achieves automatic picocell control without proportionally increasing overall system complexity
Solution Approach 2:
The system merges the flight phase monitoring function, safety decision-making function, and picocell control function into a single integrated control device. Rather than separating these functions into independent systems, the invention combines them into one unified control unit that processes information and executes control actions through integrated logic, thereby reducing total system complexity
Data Source
AI summary
A picocell in an aircraft for the wireless transmission of data between at least a mobile station in the aircraft and a base station in the aircraft in which a communications connection between the at least one mobile station in the aircraft and a subscriber in a terrestrial communications network is established via the base station. In order to enable passengers automatically the use of their mobile radio devices, when no risk of danger to the flying operation is to be expected, or otherwise to refer them to a corresponding ban, a flight control device is provided for detecting flight data and for setting up the picocell in dependence on the flight data.
