Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If PLC and RFID transponder are integrated into one device, then programming efficiency is improved and personnel requirements are reduced, but device complexity increases
Solution Approach 1:
The patent combines PLC and RFID transponder into a single integrated device, merging previously separate functions into one unified system. This allows both programmable logic control and RFID processing to be performed by the same device with a single processor, reducing the need for separate programming activities and personnel while improving overall programming efficiency.
Solution Approach 2:
The integrated device performs multiple functions including PLC processing, RFID transponder operations, and data communication through a single universal platform. The processor can execute both PLC programs and RFID protocols, making the device versatile and eliminating the need for specialized separate devices for each function.
2Loss of time
If separate programming tools are used for PLC and RFID transponder, then programming flexibility is maintained, but programming time and effort increase
Solution Approach 1:
The patent merges the programming interface and tools for both PLC and RFID transponder into a single unified programming environment. This allows programmers to access and configure both functions through one interface, significantly reducing programming time and eliminating the need to switch between separate tools while maintaining ease of operation through standardized procedures.
3Reliability
If multiple specialized personnel are required for PLC and RFID programming, then programming expertise is ensured, but operational costs increase
Solution Approach 1:
The integrated device is designed with a universal programming interface that can be operated by personnel with general automation programming knowledge. The system unifies the programming paradigm for both PLC and RFID functions, allowing a single operator to handle both tasks without requiring specialized expertise in multiple separate systems, thus reducing operational complexity while maintaining reliability.

AI summary
The device has an application program loaded from a programming device or an engineering system, and a radio frequency identification (RFID) transponder (T1) receiving and transmitting radio signals, where the RFID transponder is operatively connected to a processor. Operating and runtime systems execute the application program that is produced by using a development environment for programming a programmable logic controller, where the application program is processed cyclically.
