Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate hardware components and software applications are used for different communication protocols, then compatibility with various field devices is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent combines multiple communication protocol capabilities (HART, Fieldbus, Profibus) into a single integrated adapter device. The adapter includes multiple communication interfaces and a processor that can handle different protocols, eliminating the need for separate hardware devices for each protocol. This merging approach maintains versatility while reducing the number of components users must acquire and manage.
Solution Approach 2:
The adapter is designed as a universal communication device that can interface with field devices using multiple communication protocols through a single unit. The device includes a processor capable of executing different communication protocols and multiple communication interfaces that can adapt to various field device requirements, making one device sufficient for multiple communication needs.
2Adaptability or versatility
If multiple separate software applications are installed for different protocols, then protocol-specific functionality is improved, but ease of operation and setup time worsen
Solution Approach 1:
The patent combines multiple protocol-specific software applications into a single integrated adapter device. The processor within the adapter can execute different communication protocols (HART, Fieldbus, Profibus) through unified software firmware, eliminating the need for users to install and configure separate software applications on their computers for each protocol.
Solution Approach 2:
The adapter includes auto-detection capabilities that automatically identify the communication protocol being used by the field device and configure itself accordingly. This self-service feature eliminates the need for manual software selection and configuration by the user, simplifying the operation process while maintaining protocol-specific functionality.
3Ease of operation
If protocol auto-detection is implemented, then ease of operation is improved, but processing time and complexity worsen
Solution Approach 1:
The adapter automatically detects the communication protocol used by the field device and configures itself without user intervention. The processor analyzes incoming signals and automatically selects the appropriate communication protocol (HART, Fieldbus, or Profibus), eliminating the need for manual configuration while maintaining simplicity for the user.
