Problem
The existing electrical distribution systems for aircraft face challenges in efficiently transferring critical and safety-related data during computer replacements in electrical distribution boxes, leading to potential electrical faults and increased maintenance time due to manual data recreation and system downtime.
Innovation Solution
An electrical distribution system with a context information storage device and an updating mechanism that compares data across computers and the storage device, automatically downloading necessary data to ensure consistency and accuracy during computer replacements, reducing the risk of errors and downtime.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual data recreation is performed during computer replacement, then data accuracy can be maintained, but maintenance time increases significantly
Solution Approach 1:
The patent implements automatic copying of data from a reference computer to the replacement computer using a duplication device. This eliminates manual data recreation while ensuring data accuracy through automated bit-by-bit copying of the electrical distribution system data, directly resolving the contradiction between maintaining data accuracy and reducing maintenance time.
Solution Approach 2:
The system performs preliminary data backup and storage in a database before computer replacement occurs. The duplication device is pre-configured to automatically retrieve and transfer the necessary data when a computer is replaced, eliminating the need for manual data recreation during the maintenance operation.
2Productivity
If multiple computers are replaced simultaneously, then productivity improves, but data consistency becomes difficult to maintain
Solution Approach 1:
The duplication device automatically copies data from the database to each replacement computer in sequence, ensuring that all computers receive identical, consistent data regardless of how many are being replaced simultaneously. This automated copying process maintains data consistency while enabling rapid multi-computer replacement.
Solution Approach 2:
The system performs self-service data synchronization where the duplication device automatically detects which computers need data and transfers the necessary information without human intervention. This enables multiple computers to be replaced and synchronized simultaneously while maintaining data consistency across the entire system.
3Adaptability or versatility
If data is transferred manually using intervention sheets, then flexibility is maintained, but error risk increases
Solution Approach 1:
The system uses automated digital copying of data from the database to replacement computers, eliminating manual transcription from intervention sheets. This automated process maintains operational flexibility while dramatically reducing error risk by eliminating human transcription errors entirely.
Solution Approach 2:
The patent replaces the manual mechanical process of copying data from intervention sheets with an automated electronic duplication system. This substitution eliminates human error while maintaining the ability to adapt to different replacement scenarios through software-controlled data selection and transfer.
