Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If autonomous robotic devices retrieve physical objects without RFID tracking, then the system is simpler and cheaper, but errors in object identification and placement occur
Solution Approach 1:
RFID readers provide real-time feedback by detecting RFID tags on physical objects and verifying their locations. The computing system receives location information from RFID readers and compares it with expected locations, enabling error detection and correction through feedback loops.
Solution Approach 2:
RFID tags serve as intermediaries between physical objects and the computing system. Instead of direct visual recognition or complex sensing, the RFID tags enable reliable identification and tracking of objects throughout the facility.
2Measurement precision
If RFID readers are deployed throughout the facility to track physical objects, then object tracking accuracy improves, but system cost and complexity increase
Solution Approach 1:
RFID readers serve multiple functions: detecting RFID tags, determining object locations, verifying correct placement, and providing feedback to the computing system. This multi-functionality reduces the need for separate specialized devices.
Solution Approach 2:
RFID tags passively provide identification information when in range of readers, without requiring active scanning or complex interaction. The system leverages the natural presence of RFID tags on objects to enable tracking.
3Reliability
If manual verification of object placement is used, then errors can be detected, but productivity and speed of operation decrease
Solution Approach 1:
RFID readers automatically provide feedback on object locations and the computing system verifies correctness, enabling continuous error detection without manual intervention and maintaining high operational speed.
Solution Approach 2:
Manual verification is replaced by an automated electronic verification system using RFID readers and computing system processing, eliminating the need for human operators to physically check each object's placement.
