Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If temperature sensors are attached to moving parts and connected to a processing unit, then fault condition detection capability is improved, but device complexity and cost increase
Solution Approach 1:
The patent replaces wired mechanical connections with wireless RFID technology. Temperature sensors are integrated into RFID tags that can be attached to moving parts without physical wire connections, eliminating the complexity of wiring through moving components while maintaining temperature monitoring capability for fault detection
Solution Approach 2:
The RFID tag serves as an intermediary device that combines temperature sensing with wireless communication capability. This intermediary eliminates the need for direct wired connections between sensors and processing units, solving the problem of connecting sensors to moving parts without complex wiring
2Reliability
If RFID tags with temperature sensors are used on moving parts, then predictive monitoring capability is improved, but cost increases
Solution Approach 1:
The RFID tag performs multiple functions: it serves as both an identification tag and a temperature sensor carrier. This multi-functionality reduces overall system cost by combining what would otherwise be separate components into a single integrated unit, making predictive monitoring more cost-effective
Solution Approach 2:
The patent employs inexpensive RFID tags that can be easily attached and replaced. These low-cost tags with integrated temperature sensing provide affordable predictive monitoring capability, replacing expensive traditional sensor systems while maintaining effective fault detection
3Reliability
If wired temperature sensors are used in stationary locations, then fault detection is improved, but adaptability to moving parts deteriorates
Solution Approach 1:
Wireless RFID technology replaces wired sensor connections, enabling temperature monitoring on moving parts without physical constraints. This substitution maintains measurement accuracy while providing the adaptability needed for components in motion, overcoming the limitation of wired sensors

AI summary
An agricultural work machine, an agricultural work machine control system, and method for an agricultural work machine having RFID tags to determine a fault condition of machine components, devices, parts or systems. The RFID tags are located on, at, or near machine components or systems to sense a temperature of those components or systems. A receiver/transmitter interrogates the RFID tags and receives the sensed temperatures, and component identifiers. A controller receives the temperatures from the receiver/transmitter and compares the received temperatures to a threshold to determine whether a fault condition exists. If so, the controller transmits an alert signal to a user interface to indicate that a fault condition exists with an identified component, part, device, or system.
