Bus Node With Third Interface For Protocol Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bus node systems lack flexibility in adapting to different control tasks and protocols, limiting their ability to efficiently couple higher-level bus systems with multiple internal bus systems.
Innovation Solution
The bus node incorporates a third bus interface with separate activation capabilities, allowing for independent coupling of additional function module arrangements to the higher-level bus system, using a single circuit board with a processor to manage signal conversions between bus systems, and modular housing parts for adaptability and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a bus node is designed with only a single bus interface for coupling to a higher-level bus system, then the device complexity is reduced, but the adaptability to different control tasks and protocols is limited
Solution Approach 1:
The bus node is designed with multiple bus interfaces (first, second, and third bus interfaces) that can be separately activated, allowing a single device to perform multiple functions by coupling to different internal bus systems independently, thereby achieving adaptability without proportionally increasing complexity
Solution Approach 2:
The bus node incorporates dynamic activation capabilities where the electronic circuit can selectively activate or deactivate specific bus interfaces based on the required control task, allowing the system to adapt its functionality dynamically rather than being statically configured
2Reliability
If multiple internal bus systems are coupled to a single bus interface, then the device complexity is reduced, but the reliability of independent communication is compromised
Solution Approach 1:
The bus node divides the coupling function into separate, independent bus interfaces, where each interface can be independently activated and managed. This segmentation ensures that communication through one interface does not interfere with another, guaranteeing independent communication reliability while maintaining manageable device complexity through modular design
3Adaptability or versatility
If additional bus interfaces are added to enable separate activation of multiple function module arrangements, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The electronic circuit is designed to universally support multiple bus interfaces with separate activation capabilities, allowing the same circuitry to handle different internal bus systems through the first, second, and third bus interfaces, thereby achieving flexibility without proportionally increasing overall device complexity
