ECU Network Setting Rollback After Communication Errors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication errors can occur when a communication device connected to a network checks continuity with a communication partner after network settings have been changed, leading to further communication issues.
Innovation Solution
A communication control device that includes a setting unit to change network settings, an output unit to notify connected devices of the change, and a control unit that, upon detecting a communication error, returns the network settings to their pre-change state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network settings are changed to improve network functionality or performance, then network adaptability is improved, but communication reliability deteriorates due to potential communication errors
Solution Approach 1:
The system performs preliminary actions by notifying communication devices before network settings are changed, allowing them to prepare for the change. This preliminary notification helps devices adjust their communication patterns in advance, reducing the likelihood of communication errors when the actual setting change occurs.
Solution Approach 2:
The system implements feedback mechanisms where communication devices report communication status and errors back to the network control device. This feedback loop allows the system to detect communication errors caused by setting changes and trigger appropriate error handling procedures, thereby maintaining communication reliability during network adaptation.
2Productivity
If network settings are changed without notification to improve operation speed, then productivity is improved, but communication reliability deteriorates due to undetected errors
Solution Approach 1:
The system sends notification messages to communication devices before applying network setting changes. This preliminary action allows devices to prepare their communication stacks and routing tables in advance, enabling the actual setting change to be applied quickly without causing communication disruptions, thus maintaining both productivity and reliability.
Solution Approach 2:
The system establishes feedback channels where communication devices report their status and any communication errors to the network control device. This real-time feedback enables rapid detection of issues and allows the system to respond quickly, maintaining high operation speed while ensuring communication reliability through error detection and correction.
3Stability of the object's composition
If network settings are changed and errors are not immediately detected to maintain system stability, then system stability is improved, but communication reliability deteriorates due to persistent errors
Solution Approach 1:
The system implements continuous feedback monitoring where communication devices regularly report their communication status to the network control device. This feedback mechanism allows the system to maintain stability by detecting errors early and triggering appropriate error handling procedures, preventing persistent errors from degrading communication reliability while keeping the overall system stable.
Solution Approach 2:
The system enables communication devices to autonomously detect and report their own communication errors to the network control device. This self-service capability allows devices to monitor their own communication health and immediately report issues, enabling the system to maintain stability while ensuring reliable communication through rapid error detection and response.
