Solution Overview
Problem
Existing transmission networks with integrated functional nodes for information distribution face challenges in enhancing security and operational reliability, particularly in high-failure-tolerance applications like on-board avionics systems.
Innovation Solution
The network design includes interconnected loops with nodes featuring distribution modules and network interface modules, where interface modules of certain nodes in one loop are connected to distribution modules of nodes in another loop, enabling enhanced message exchange and increased resistance to failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network interface modules are connected only within the same loop, then the network structure is simple and easy to implement, but the resistance to failures and operational reliability is reduced
Solution Approach 1:
The patent transitions from a single-loop two-dimensional structure to a multi-loop three-dimensional interconnected structure. Network interface modules are connected not only within their own loop but also to distribution modules in other loops, creating vertical and diagonal connections that add dimensional complexity while significantly improving failure resistance through multiple redundant paths.
Solution Approach 2:
The network is divided into multiple independent loops, each with its own distribution modules and network interface modules. This segmentation allows the network to isolate failures to specific loops while maintaining operational integrity through inter-loop connections, thereby improving overall reliability without requiring complete system redesign.
2Reliability
If multiple interconnected loops are implemented, then information exchange opportunities increase and security improves, but the device complexity and implementation difficulty increase
Solution Approach 1:
Distribution modules and network interface modules are designed with universal connection capabilities that allow them to function within their own loop and simultaneously connect to other loops. This multi-functionality enables the same hardware components to participate in multiple communication paths, improving reliability without requiring separate dedicated components for each loop.
Solution Approach 2:
The patent merges the functions of single-loop communication with multi-loop interconnection by having network interface modules connect to distribution modules across different loops. This combining approach allows information to flow through multiple loops simultaneously, increasing exchange opportunities and security while utilizing existing module architectures.
3Adaptability or versatility
If nodes are connected to multiple loops, then message distribution resilience improves, but the complexity of message distribution and network management increases
Solution Approach 1:
The distribution modules implement dynamic message routing capabilities that automatically adapt to network conditions and failure states. Messages can be dynamically redirected through different loops and paths based on real-time network status, providing flexibility in message distribution while the system manages the complexity through automated routing logic rather than static fixed paths.
