Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transmission systems using multiple lanes face challenges in dynamically changing the number of lanes while maintaining transmission speed, due to limitations in physical resources and skew corrections, which restricts flexibility in lane configuration.
Innovation Solution
A transmission system with a transmitter, relay, and receiver that includes mechanisms for detecting and correcting data sequence disalignment by inserting channel information into data sequences, allowing for dynamic changes in the number of lanes by redistributing data across channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple lanes are combined to increase transmission speed, then communication bandwidth is improved, but the number of lanes cannot be changed in the course of the transmission line
Solution Approach 1:
The patent segments the transmission line into multiple independent channels, each capable of carrying data sequences. By inserting channel information into data sequences, each channel can be independently identified and managed, enabling flexible reconfiguration of lane combinations without affecting overall transmission performance.
Solution Approach 2:
The patent implements dynamic lane configuration by allowing the number of channels to be changed in the course of the transmission line. The system can dynamically adjust the number of lanes between transmitter and relay, and between relay and receiver, enabling adaptive bandwidth optimization based on actual transmission needs.
2Adaptability or versatility
If the number of lanes is changed in the course of the transmission line, then lane configuration flexibility is improved, but data sequence disalignment occurs due to differences in arrival time
Solution Approach 1:
The patent applies preliminary action by inserting channel information into data sequences before transmission. This allows the receiver to pre-process and identify the origin of each data sequence, enabling accurate reassembly even when lanes are dynamically reconfigured and data arrives at different times.
Solution Approach 2:
The patent implements feedback mechanisms where channel information is embedded in transmitted data sequences and subsequently used by the receiver to verify and correct data sequence alignment. This feedback loop ensures that even with dynamic lane changes, the system can detect and correct disalignment issues.
3Adaptability or versatility
If channel information is inserted into data sequences, then dynamic lane changes are enabled, but device complexity increases
Solution Approach 1:
The patent merges channel information with data sequences by inserting the channel identifier directly into the data structure. This combining approach avoids the need for separate control channels or additional hardware components, achieving flexible lane reconfiguration while minimizing increases in system complexity.

AI summary
Provided is a transmission system with increased degree of freedom in a lane configuration, which corrects disalignment of data sequences in respective channels due to differences in arrival time, thereby freely changing a number of lanes. The transmission system includes: a transmitter; a relay; and a receiver, the transmitter inputting data to be transmitted to the receiver, the relay transmitting the data transmitted by the transmitter to the receiver, the receiver receiving the data transmitted by the relay. The transmitter inserts into the data sequences channel information indicating a channel to which the data sequence is to be output. The relay corrects, based on the channel information, disalignment in an order of arrival of the data sequences received via a plurality of channels, the disalignment being generated by the differences in arrival time of the data sequences among the channels.
