Transistor Igniter Fault Encoding for Protective Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transistor control devices in transport vehicles are prone to malfunctions, which can lead to significant damage or destruction, and lack effective mechanisms for detecting and encoding fault data to prevent further damage.
Innovation Solution
A transistor control device with a supervisory module, igniter, and management module that detects malfunctions, generates an alert signal with encoded fault data, and prevents further control to protect the transistor and igniter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If fault detection and encoding capabilities are added to the igniter, then diagnostic information availability is improved, but device complexity increases
Solution Approach 1:
The igniter is designed to perform multiple functions: it not only ignites the pyrotechnic composition but also detects malfunctions, generates fault data, and encodes diagnostic information in alert signals. This multi-functionality resolves the contradiction by consolidating diagnostic capabilities within the existing igniter structure rather than adding separate detection devices.
Solution Approach 2:
The monitoring module and igniter are merged into an integrated system where the igniter contains both the ignition function and the fault detection/encoding functions. This combination allows fault information to be captured at the source without requiring separate complex diagnostic equipment.
2Reliability
If real-time monitoring and fault detection are implemented, then system reliability is improved, but device complexity increases
Solution Approach 1:
The monitoring module continuously monitors the transistor and igniter operation, providing real-time feedback about system status. When a malfunction is detected, the system generates an alert signal with encoded fault information, enabling timely intervention and maintaining system reliability through continuous monitoring and feedback mechanisms.
3Loss of information
If fault data is encoded in alert signals, then diagnostic capability is improved, but signal processing complexity increases
Solution Approach 1:
The igniter encodes fault data by modifying parameters of the alert signal, such as using different pulse widths, frequencies, or patterns to represent different fault conditions. This parameter-based encoding allows compact representation of diagnostic information without requiring complex communication protocols or data structures.
