Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If access control for automation apparatus configuration is implemented across large and distributed industrial sites, then data security and configuration control are improved, but device complexity and implementation difficulty increase
Solution Approach 1:
The access control system is segmented into multiple independent components: electronic tags for user identification, readers for authentication, user interfaces for local interaction, and communication interfaces for network connectivity. This segmentation allows each component to be implemented and managed separately, reducing overall system complexity while maintaining security across distributed sites.
Solution Approach 2:
The patent introduces intermediate components such as the reader device that mediates between the electronic tag and the automation apparatus, and the user interface that mediates between the local user and the system. These intermediaries simplify the interaction model and reduce implementation complexity by providing standardized interfaces.
2Ease of operation
If multiple communication interfaces and protocols are supported for remote and local access, then usability and accessibility are improved, but device complexity increases
Solution Approach 1:
The access control apparatus is designed with multi-functional communication capabilities, supporting both local user interface interactions and remote networked service communications through standardized protocols. This universality allows the same device to serve multiple purposes (local configuration and remote management) without requiring separate specialized systems, improving accessibility while managing complexity through protocol standardization.
3Reliability
If electronic tag-based authentication is implemented for user access, then access control security is improved, but ease of operation decreases due to additional authentication steps
Solution Approach 1:
The patent replaces traditional mechanical or manual authentication methods (such as passwords or physical keys) with electronic tag-based authentication using RFID or similar wireless technologies. This substitution maintains security while improving ease of operation, as users can authenticate by simply presenting their electronic tag without manual input, reducing the cognitive and physical effort required.
