Multi-lane Communication Interface Dynamic Lane Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-lane communication systems have fixed lane configurations, long fault recovery times, and do not support dynamic adaptation to changes in lane status, leading to inefficiencies and data integrity issues.
Innovation Solution
A multi-lane communication interface that dynamically adapts to changes in lane status by establishing symbol synchronization, detecting and responding to lane status changes, and allowing an arbitrary number of unidirectional and bidirectional lanes, ensuring data integrity and power-saving capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional multi-lane communication systems use fixed lane configurations, then device complexity is reduced and ease of manufacture is improved, but adaptability to changes in lane status deteriorates and fault recovery time increases
Solution Approach 1:
The patent implements dynamic lane configuration where the multi-lane communication interface can adapt its operational parameters based on real-time lane status. The system dynamically detects lane failures and reconfigures traffic distribution across remaining functional lanes, transforming a static fixed configuration into a dynamic adaptive system that responds to changing conditions.
Solution Approach 2:
The system employs feedback mechanisms through lane status detection and monitoring. The interface continuously monitors lane health and uses this feedback information to trigger reconfiguration events, adjusting traffic distribution and lane allocation based on the detected status, thereby achieving adaptive behavior through closed-loop control.
2Reliability
If conventional systems use fixed lane configurations, then ease of operation is improved, but fault recovery time increases and productivity decreases
Solution Approach 1:
The system performs preliminary actions by pre-establishing lane status detection capabilities and pre-configuring alternative traffic paths. When a lane failure is detected, the reconfiguration process is already primed and can execute immediately, reducing the time penalty associated with fault recovery by having the response mechanism prepared in advance.
Solution Approach 2:
The multi-lane communication interface implements self-service through automatic lane status detection and autonomous reconfiguration. The system detects lane failures and redistributes traffic without external intervention or manual reconfiguration, enabling the interface to service itself and maintain operational reliability autonomously.
3Productivity
If dynamic lane adaptation is implemented, then adaptability and fault recovery are improved, but device complexity and measurement precision requirements increase
Solution Approach 1:
The patent segments the multi-lane communication interface into independent lane monitoring units and traffic distribution modules. Each lane can be detected and monitored independently, and traffic routing decisions are made at granular levels, allowing complex adaptive behavior to emerge from simpler modular components rather than requiring monolithic complex detection systems.

AI summary
A multi-lane communication interface is provided for use in a link, such as SpaceFibre used on-board spacecraft. The interface has logic, when operating at a near end in cooperation with a far-end multi-lane communication interface, to: establish symbol synchronisation with the far-end over one or more lanes; send and receive data words to and from the far-end while maintaining the symbol synchronisation (A); detect a change in lane status; and upon detection of the change in lane status and while maintaining the symbol synchronisation: stop sending (B) data words; send (B) near-end lane-status control words to the far end instead of data words, until it is determined that the near end is ready to send data words, then resume sending (C) data words; and send (C) near-end lane-alignment signals to the far end, until a data word is received from the far end.
