Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual data recording with pen and paper is used, then data recording can be performed with simple equipment, but operator effort and time consumption increase significantly
Solution Approach 1:
The system enables automatic data recording where the aircraft systems themselves generate and transmit data without manual intervention. The data recording function automatically captures flight parameters, stores them, and manages transmission, eliminating the need for operators to manually record data while reducing their workload.
Solution Approach 2:
The patent replaces manual mechanical recording (pen and paper) with electronic automated systems. Data is captured electronically from aircraft sensors and systems, stored in digital format, and transmitted automatically, substituting the mechanical manual process with an electronic automated one.
2Extent of automation
If predefined automatic data recording is used, then data recording is automated, but flexibility and real-time configuration capability are lost
Solution Approach 1:
The data recording function is designed to be dynamic and reconfigurable in real-time. Operators can modify recording parameters, select different data sets, change storage locations, and adjust transmission settings during flight operations, allowing the system to adapt to changing requirements while maintaining automated operation.
Solution Approach 2:
The system is designed to handle multiple data types, storage locations, and transmission methods through a single unified data recording function. It can record various flight parameters, store data in multiple locations (aircraft storage, ground storage, cloud storage), and transmit through different channels, providing versatility while maintaining automation.
3Device complexity
If data recording is tied to aircraft configuration, then data recording is simplified, but real-time changes and adaptability are prevented
Solution Approach 1:
The configuration of the data recording system is made dynamic, allowing operators to change recording parameters, data sets, storage locations, and transmission settings in real-time based on operational needs, rather than being fixed to a predetermined aircraft configuration.
Solution Approach 2:
The data recording function is segmented into independent configurable parameters (data selection, duration, storage location, transmission settings) that can be modified independently without changing the entire system configuration, enabling flexible real-time adjustments.
4Reliability
If certified devices only are used for data recording, then data integrity and reliability are ensured, but device selection and versatility are limited
Solution Approach 1:
The data recording function is designed to work with multiple types of devices including both certified and non-certified devices. The system maintains reliability through standardized data handling and validation while allowing flexible device selection for different recording and storage needs.
Solution Approach 2:
The data recording function acts as an intermediary layer between various data sources and storage/transmission destinations. It standardizes data handling and validates information flow, ensuring reliability regardless of whether the connected devices are certified or non-certified, while maintaining compatibility with diverse device types.
Data Source
AI summary
A system and method for dynamically recording vehicle data are provided. The system comprises an electronic unit onboard a vehicle, a data recording function hosted in the electronic unit, and one or more electronic data producers in operative communication with the data recording function. The data recording function is operative to receive a request specifying data parameters that at least include an identified electronic data set to record, a duration for the data recording, and a destination for the data recording. The data recording function is also operative to process the request based on the data parameters to produce a set of real time recorded data from the one or more electronic data producers, and to send the set of recorded data to a data storage location based on the destination in the request.
