Solution Overview
Problem
Current process control systems lack an efficient method to display and communicate comprehensive information related to industrial processes across multiple devices, limiting real-time monitoring and control capabilities.
Innovation Solution
An output device equipped with sensors and a display, communicatively coupled to a controller and/or portable field device, acquires and transmits information, and receives calculated values to display process parameters, enabling visualization of process conditions across the system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If information is transmitted only to a central controller, then system complexity is reduced, but real-time monitoring capability at local devices is limited
Solution Approach 1:
The patent divides the information display function across multiple output devices rather than centralizing it. Each output device can independently display information received from sensors, enabling distributed real-time monitoring without requiring all data to flow through a central controller, thus resolving the contradiction between information accessibility and system complexity
Solution Approach 2:
Output devices are given multiple functions: they not only display information from their own sensors but also receive and display information from other output devices. This multi-functionality enables comprehensive real-time monitoring across the system while maintaining a relatively simple distributed architecture
2Productivity
If multiple output devices display comprehensive process information, then real-time monitoring capability is improved, but device complexity increases
Solution Approach 1:
The patent combines the display of local sensor information with remote information from other output devices into a single unified display at each output device. This merging enables operators to monitor multiple process parameters simultaneously at any location, improving monitoring efficiency without requiring operators to check multiple separate devices, thus resolving the contradiction between productivity and device complexity
