Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flight data is stored in a single storage device, then device complexity is reduced, but data reliability deteriorates due to risk of data loss in accidents
Solution Approach 1:
The storage system is divided into multiple independent storage devices (primary storage device and secondary storage device) that separately store flight data. This segmentation ensures that if one device fails or is damaged in an accident, the other device still contains the data, thereby improving data protection without requiring a complex centralized backup system.
Solution Approach 2:
The patent implements copying of flight data to multiple storage devices. The primary storage device stores data during normal operation, and the secondary storage device stores copies of the same data. This copying mechanism ensures data redundancy and protection against data loss while maintaining relatively simple storage device structures.
2Reliability
If multiple storage devices are used to protect data, then data reliability is improved, but ease of operation deteriorates due to difficulty in checking recorded information
Solution Approach 1:
The patent introduces a debriefing solution equipment as an intermediary device that interfaces with both storage devices and the user. This equipment provides a unified interface for checking and analyzing flight data from multiple storage devices, eliminating the need for users to manually access and compare multiple storage devices. The debriefing solution equipment processes and displays data in a convenient manner, improving ease of operation while maintaining data protection through multiple storage devices.
3Measurement precision
If comprehensive flight data is recorded from multiple sources, then measurement precision is improved, but device complexity increases due to multiple image obtaining devices
Solution Approach 1:
The patent merges multiple image obtaining devices (digital cameras, radar devices) into a unified recording system that captures flight data from various sources simultaneously. The recording device integrates data from all these sources and stores them in a coordinated manner, achieving comprehensive and precise flight data recording without requiring complex separate systems for each data source.
Solution Approach 2:
The recording device is designed with multi-functionality to handle various types of data from different sources (digital camera images, radar data, etc.). This universal recording device can process and store multiple data types through a single system, reducing overall device complexity while maintaining high measurement precision through comprehensive data collection.
4Productivity
If real-time data recording and analysis is implemented, then productivity is improved, but loss of time increases due to data processing requirements
Solution Approach 1:
The patent implements preliminary action by continuously recording flight data in real-time during the flight operation itself, rather than waiting for post-flight analysis. The recording device captures data as it occurs, and the debriefing solution equipment can immediately analyze this data during or after the flight, providing timely feedback for training purposes. This eliminates the time loss associated with manual data collection and initial processing, while maintaining high productivity through efficient real-time handling.
