Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing RFID systems for operator control units (OCUs) lack the ability to dynamically change configurations such as operating frequency and address to adapt to specific industrial machines, leading to inefficiencies in remote control operations and potential unauthorized access.
Innovation Solution
Implementing RFID systems and methods that allow for the reading of RFID tags associated with specific machines to retrieve and apply OCU configuration data, enabling the OCU to be customized for operation with only the intended machine, thereby ensuring secure and efficient remote control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RFID systems are implemented to read tags and retrieve OCU configuration data, then secure and efficient remote control is achieved, but device complexity increases
Solution Approach 1:
The patent introduces an RFID tag as an intermediary component that stores OCU configuration data. The tag acts as a mediator between the machine control system and the OCU, enabling secure configuration transfer without direct complex communication protocols. The RFID reader serves as another intermediary that facilitates data retrieval from the tag to the OCU, simplifying the overall security architecture while maintaining reliability.
Solution Approach 2:
The system performs preliminary actions by pre-storing OCU configuration data (including security credentials, operating parameters, and machine-specific settings) in the RFID tag before the OCU needs to control the machine. This advance preparation eliminates the need for complex real-time authentication and configuration processes, reducing system complexity while ensuring secure remote control.
2Reliability
If OCU configuration is customized for each specific machine using RFID tags, then unauthorized access is prevented, but ease of operation decreases
Solution Approach 1:
The OCU performs self-service by automatically retrieving and applying its configuration data from the RFID tag when brought near the machine. The system eliminates manual configuration steps, authentication complexities, and technician intervention requirements. The OCU autonomously reads the tag, extracts configuration parameters, and configures itself, thereby preventing unauthorized access while maintaining ease of operation.
Solution Approach 2:
The patent replaces manual mechanical configuration processes (physical setup, wired connections, manual parameter entry) with wireless RFID-based automatic configuration. This substitution eliminates the need for complex manual operations while maintaining security through machine-specific configuration data stored in the RFID tag.
3Adaptability or versatility
If RFID reader is manually transported to machine location for tag reading, then flexibility is improved, but loss of time increases
Solution Approach 1:
The system employs periodic action by enabling rapid, repeated RFID tag readings as the OCU is brought near the machine. The short-range wireless communication allows for quick data transfer in a matter of seconds, eliminating time-consuming manual configuration processes while maintaining the flexibility of mobile OCU deployment.
