Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing industrial process control and automation systems have high costs and complexity due to the need for multiple hardware components, extensive cabling, and numerous intrinsically safe barriers, which limits control performance and increases maintenance costs.
Innovation Solution
An intelligent field input/output (I/O) terminal that combines control, communication, and safety functions into a single, compact device with multiple I/O channels, integrated intrinsically safe barriers, and peer-to-peer communication capabilities, allowing for scalable, weather-resistant, and network-connected installations in industrial facilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional gather-scatter topology with multiple hardware components is used, then I/O functions can be performed, but cabling costs and physical footprint increase significantly
Solution Approach 1:
The patent combines multiple I/O functions, communication interfaces, and processing capabilities into a single field installable module. This consolidation eliminates the need for separate hardware components and extensive cabling, directly reducing the physical footprint while maintaining all necessary I/O functions.
Solution Approach 2:
The field installable module is designed as a universal device that can perform multiple I/O functions simultaneously through its multiple communication interfaces and channels. This multi-functionality allows a single device to replace multiple specialized components, reducing overall system footprint.
2Reliability
If multiple cables and intrinsically safe barriers are deployed for each I/O function, then safety and control reliability are improved, but system complexity and maintenance costs increase
Solution Approach 1:
The patent integrates multiple communication interfaces and intrinsically safe barriers within a single field installable module. This consolidation reduces the number of discrete components that need to be installed, configured, and maintained, thereby lowering system complexity while preserving safety and reliability.
Solution Approach 2:
The field installable module incorporates integrated intrinsically safe barriers that automatically ensure safety compliance without requiring external barriers for each I/O function. This self-contained design simplifies the system architecture and reduces maintenance burden.
3Adaptability or versatility
If extensive cabling is used to connect each I/O function to the control room, then complete I/O coverage is achieved, but installation and maintenance costs increase
Solution Approach 1:
The patent transitions from a centralized control room architecture to a distributed field-based architecture. By placing communication and processing capabilities directly at the field devices, the system eliminates the need for extensive cabling back to the control room, thereby reducing installation costs while maintaining comprehensive I/O coverage.
Solution Approach 2:
The field installable module serves as a universal interface that can connect to multiple field devices through multiple I/O channels while communicating with the control system through a single network connection. This consolidates what would otherwise require multiple separate cabling paths into a single connection point.
