Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-lane serial transmission, frequent renegotiation occurs when transmission qualities of multiple lanes deteriorate alternately, leading to suspended data transfers.
Innovation Solution
A transfer apparatus and method that switch between distribution, nonredundant, and redundant modes without renegotiation, using a transmission control unit to output data on multiple lanes, ensuring continuous data transfer by error checking and switching modes based on serial number patterns and CRC verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-lane serial transmission is performed under severe transmission conditions, then data transfer capability is maintained, but error rate increases due to environmental conditions such as power supply quality and temperatures
Solution Approach 1:
The patent changes the transmission mode parameter from single-lane to multi-lane serial transmission to maintain data transfer capability under severe conditions. By utilizing multiple lanes with different characteristics, the system adapts to environmental variations in power supply quality and temperature, ensuring continuous operation despite deteriorating conditions.
Solution Approach 2:
The patent implements error detection and correction mechanisms beforehand to cushion against the increased error rate. Checksum verification and retransmission protocols are prepared in advance to handle errors that occur during multi-lane transmission under severe environmental conditions, preventing complete transfer failure.
2Reliability
If renegotiation is performed to detect and isolate faulty lanes, then transmission quality is improved, but data transfer is suspended during the renegotiation process
Solution Approach 1:
The patent performs preliminary error detection using checksum verification on received data packets. By detecting errors early in the transmission process and identifying faulty lanes through pattern recognition, the system prepares for swift lane isolation without requiring complete renegotiation, thus minimizing data transfer suspension.
Solution Approach 2:
The patent implements dynamic lane management where individual lanes can be independently activated or deactivated based on real-time error detection. This dynamic adjustment allows the system to maintain data transfer on healthy lanes while isolating faulty ones, avoiding complete transfer suspension and enabling continuous operation with adaptive quality adjustment.
3Reliability
If the same data is transferred using multiple lanes in redundant mode, then data integrity is improved, but transmission efficiency decreases due to increased data volume
Solution Approach 1:
The patent segments data into multiple packets distributed across different lanes, with each packet containing a portion of the original data and error detection codes. This segmentation enables parallel transmission while maintaining integrity through distributed verification, improving efficiency compared to complete redundant transmission of identical data on all lanes.
Solution Approach 2:
The patent dynamically changes the transmission mode parameter between redundant and distributed modes based on lane health status and data integrity requirements. When lanes are healthy, distributed mode improves efficiency; when errors are detected, redundant mode ensures integrity. This adaptive parameter change optimizes the balance between reliability and productivity.
