Solution Overview
Problem
Current systems lack an efficient and flexible method for communicating with and controlling multiple electrical machines, such as motors, and processing data across various distances and interfaces.
Innovation Solution
A method and apparatus that utilize a machine interface for local communication with electrical machines and a communication interface, like Ethernet, for long-distance communication, enabling efficient data exchange between electrical machines and other devices, including IoT devices, through a computer-implemented system with dynamically bindable libraries and sub-functions for distributed application control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single communication interface is used for all electrical machines, then device complexity is reduced, but communication flexibility and adaptability to different distance requirements deteriorate
Solution Approach 1:
The communication system is segmented into two distinct interface types: a machine interface for local communication with individual electrical machines and a communication interface (Ethernet) for long-distance communication with further electrical machines. This segmentation allows each interface to be optimized for its specific communication scenario, resolving the contradiction between simplicity and adaptability.
Solution Approach 2:
The apparatus is designed with multi-functional communication capabilities by integrating both machine interface and Ethernet communication interface functions into a single system. This allows the same apparatus to handle both local and remote communication tasks, providing versatility without requiring multiple separate devices.
2Stability of the object's composition
If a dedicated master role is assigned for controlling electrical machines, then control stability is improved, but system reliability and fault tolerance deteriorate due to single point of failure
Solution Approach 1:
Instead of assigning a dedicated master role to one apparatus, the system inverts the control architecture by enabling any apparatus to assume control responsibilities. Further electrical machines can directly control the first electrical machine through the communication interface, distributing control authority across multiple nodes and eliminating the single point of failure associated with a dedicated master.
Solution Approach 2:
The electrical machines are empowered to participate in mutual control and data exchange without requiring a central master. Each machine can independently communicate and coordinate with others through the dual-interface system, enabling self-organizing control that improves both reliability and distributed decision-making.
3Speed
If local machine interface is used for communication, then communication speed and response time are improved, but communication range and network coverage deteriorate
Solution Approach 1:
The system merges two communication paradigms by combining the fast, responsive machine interface for local communication with the extended-range Ethernet communication interface for remote communication. This hybrid approach allows the system to achieve both high-speed local response and wide-area network coverage simultaneously.
