Solution Overview
Problem
In control systems with multiple operator consoles, conflicting control signals can lead to unwanted responses or fault states in output devices, and troubleshooting is complicated due to the physical remoteness of system nodes.
Innovation Solution
An interface device with a circuit board, conductive pathways, and connectors is used to coordinate control between multiple operator consoles and an output device, employing switches to manage communication links and prevent conflicting signals, and a communication network to transmit device selection and control inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple operator consoles are allowed to transmit control signals to output devices simultaneously, then system versatility and operator flexibility are improved, but conflicting control signals may cause unwanted responses or fault states in output devices
Solution Approach 1:
The patent introduces an interface device as an intermediary component between multiple operator consoles and output devices. This interface device includes a circuit board with conductive pathways, connectors for receiving signals from multiple consoles, and switching mechanisms that selectively route control signals. The intermediary manages signal conflicts by enabling only one console to transmit control signals to a specific output device at a time, while still allowing multiple consoles to be connected to the system for versatile operation.
2Ease of operation
If operator consoles and output devices are physically remote from each other, then system layout flexibility and operator safety are improved, but troubleshooting becomes more difficult
Solution Approach 1:
The interface device serves as a centralized intermediary location that consolidates signal routing functions. By placing the interface device at a known physical location with accessible connectors and switching mechanisms, operators can physically access and troubleshoot the system without needing to be near the remotely located consoles or output devices. The interface device becomes a focal point for diagnostics and repairs.
Solution Approach 2:
The patent employs visual indicators such as LEDs that change color or illuminate to indicate the status of control signal routing and console selection. These visual cues provide immediate feedback about system state without requiring physical inspection of remote components, thereby facilitating easier troubleshooting of remotely distributed system elements.
3Reliability
If an interface device with multiple connectors and switches is introduced to coordinate control signals, then signal conflict prevention is improved, but device complexity increases
Solution Approach 1:
The interface device is designed with modular segmentation, where the circuit board is divided into distinct functional sections: connector interfaces for each console, separate conductive pathway groups for different signal types, and individual switching mechanisms for each output device. This segmentation allows the complex functionality to be organized into manageable, independent modules that can be individually tested and maintained.
Solution Approach 2:
The interface device employs universal connector designs and standardized conductive pathways that can handle multiple types of control signals through the same physical infrastructure. The switching mechanisms are designed to work with various console and output device configurations, reducing the need for specialized components for each specific connection type, thereby managing complexity through multi-functionality.
