Communication Control Device Redundancy via Wired Wireless Merging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication networks struggle to easily realize redundancy due to the need for multiple physical communication ports, which is challenging especially when node size is reduced.
Innovation Solution
A communication control device equipped with a first wired communication unit, a second wired communication unit connected to a node, a wireless communication unit, and identification and communication control units that establish communication with another device via a wireless network when connected via a wired network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each node is connected to a plurality of paths in a wired manner to achieve redundancy, then communication reliability is improved, but the number of communication ports required increases
Solution Approach 1:
The patent combines wired and wireless communication interfaces into a unified communication control device. The wired communication unit provides stable primary communication, while the wireless communication unit provides backup redundancy, merging both communication modes into one device to achieve reliability without requiring multiple wired ports
Solution Approach 2:
The communication control device is designed with multi-functionality, supporting both wired and wireless communication capabilities within a single device. This allows the device to adapt to different communication scenarios and provide redundancy without requiring separate dedicated ports for each communication mode
2Reliability
If multiple communication ports are provided to enable redundant network configuration, then network redundancy is achieved, but device size increases
Solution Approach 1:
The patent merges multiple communication functions (wired and wireless interfaces) into a single integrated communication control device. This consolidation achieves network redundancy through functional diversity rather than physical port multiplication, thereby maintaining compact node size while providing backup communication paths
3Ease of manufacture
If wireless communication is used to reduce the number of communication ports, then ease of installation is improved, but communication stability may deteriorate
Solution Approach 1:
The communication control device dynamically selects between wired and wireless communication modes based on operational conditions. The wired interface serves as the primary stable connection, while the wireless interface provides dynamic backup capability, allowing the system to adapt to different scenarios and maintain stability while benefiting from the installation ease of wireless communication
