Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional network end systems require separate switches for connection, limiting flexibility and increasing cabling complexity in topologies like AFDX networks used in aircraft systems and industrial automation.
Innovation Solution
A hybrid network end system device integrating a switch with multiple ports allows direct connection of end systems without additional switches, enabling flexible configurations in star, ring, and mixed topologies, supporting AFDX protocols and enhancing redundancy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If separate switches are used for connection in conventional network end systems, then network functionality is achieved, but device complexity and cabling requirements increase
Solution Approach 1:
The patent combines the end system functionality and switch functionality into a single integrated device. The end system unit and switch are merged into one physical device with shared components including power supply, housing, and control logic, eliminating the need for separate switch devices and reducing overall network complexity while maintaining redundancy capabilities through integrated dual-port switching
Solution Approach 2:
The hybrid network end system device performs multiple functions simultaneously: it operates as an end system for data processing, as a switch for data forwarding between network segments, and as a redundancy mechanism through dual-port connectivity. This multi-functionality reduces the number of specialized devices needed in the network
2Ease of operation
If additional switches are used for direct connection, then connectivity is improved, but cabling requirements and installation complexity increase
Solution Approach 1:
By merging end system and switch functions into one device, the patent reduces the number of connection points and cable segments needed. The integrated device requires fewer cables to achieve the same connectivity that would otherwise require multiple separate switches and associated cabling infrastructure
3Adaptability or versatility
If separate switches are used, then network functionality is achieved, but flexibility in topology configurations is limited
Solution Approach 1:
The integrated end system switch can operate in multiple topology configurations (star, ring, mesh) by utilizing its dual-port switch architecture. The device can function as an AFDX end system, an Ethernet switch, or a redundancy appliance, providing versatile adaptability to different network requirements without requiring additional specialized devices
