Network Component Port-Based Configuration for Vehicle Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Identical network components in transportation vehicles cannot be individually configured within a network due to addressing mechanisms that lead to address conflicts, as they do not know their physical location on the network switch, hindering data transmission to the correct location.
Innovation Solution
A method and device that transmit configuration messages to network components via a network switch, informing them of their physical port connection, allowing them to reconfigure based on their role and location, using Ethernet standard options like 100BASE-T1 and IPv6 addresses, and multicast addresses to ensure correct data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If identical network components are used in transportation vehicles, then manufacturing costs and logistics are reduced, but address conflicts occur and components cannot be individually configured within the network
Solution Approach 1:
The patent applies local quality by assigning unique physical port identifiers to each network component based on its specific connection location in the vehicle network. Each component receives a configuration message containing its port identifier, enabling it to distinguish itself from other identical components through its local physical characteristic rather than requiring hardware differentiation.
Solution Approach 2:
The patent changes the addressing parameter from hardware-based identification to software-based port identifier assignment. By transmitting configuration messages that contain port-specific information during system initialization, identical components can adopt different network addresses and roles dynamically, resolving address conflicts without manufacturing variations.
2Reliability
If network components are configured individually, then address conflicts are avoided, but additional components and logistics are required
Solution Approach 1:
The patent implements universality by using a single standardized network component design that can serve multiple different roles within the vehicle network. The same physical component can be configured as different network nodes depending on its port identifier assignment, eliminating the need for multiple specialized component types while maintaining proper network functionality.
Solution Approach 2:
The patent uses configuration messages as information copies that convey port identifier data to network components. Instead of creating physical copies or variations of components, the system transmits digital configuration data that enables identical hardware to assume different network identities and functions based on their physical connection points.
3Ease of operation
If address conflicts occur in the network, then data transmission to the correct location is hindered, but network complexity increases
Solution Approach 1:
The patent applies preliminary action by assigning unique port identifiers to each network component during system initialization before data transmission begins. Configuration messages are transmitted to all components upfront, establishing their unique addresses and roles in advance, which prevents address conflicts during subsequent data transmission operations without requiring complex conflict resolution mechanisms.
Data Source
AI summary
A method for configuring identical network components wherein network components are each connected to a physical port of a network switch via a network cable. An additional network station is also connected to the network switch. Configuration messages are transmitted from the additional network station to the network components wherein the configuration message of each network component communicates the physical port of the network switch to which the network component is connected. The network component performs a reconfiguration of its function in the network corresponding to the connection to the physical port.
