Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital information transfer systems, such as those used in aircraft, fail to protect against voltage faults like 28 VDC short circuits and are unable to quickly recover from such faults.
Innovation Solution
A digital information transfer system with an electronic fault detection module that compares output transmission line voltages to input voltages, triggering an electronic fault protection module to disconnect the driver unit from faulty lines and automatically re-establish connectivity when the fault is resolved.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional digital information transfer systems are used, then the system structure is simple, but the system cannot protect against voltage faults such as 28 VDC short circuits
Solution Approach 1:
The patent introduces an intermediary fault protection module between the driver unit and the output transmission line. This module includes a fault detection circuit that monitors voltage levels and a protection circuit that disconnects the driver unit when faults are detected, preventing direct damage from voltage faults while maintaining system functionality.
Solution Approach 2:
The fault protection module is segmented into distinct functional components: a fault detection circuit that independently monitors voltage conditions and a protection circuit that independently executes disconnection actions. This segmentation allows each component to perform its specific function efficiently while contributing to overall system reliability.
2Productivity
If conventional digital information transfer systems are used, then the system design is simple, but the system cannot quickly reestablish operation after fault removal
Solution Approach 1:
The fault protection module implements a feedback mechanism where the fault detection circuit continuously monitors the output transmission line voltage and provides real-time status information to the protection circuit. When the fault condition is removed and voltage returns to normal levels, the feedback signal automatically triggers reconnection of the driver unit, enabling quick recovery without manual intervention.
Solution Approach 2:
The system performs self-diagnosis and self-recovery through the automated fault detection and protection mechanisms. The fault detection circuit automatically identifies fault conditions, the protection circuit automatically disconnects to prevent damage, and when the fault is removed, the system automatically reestablishes operation without requiring external intervention or complex recovery procedures.
