Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If passive RFID tags are used for autonomous appliance communication, then energy consumption is reduced and system simplicity is improved, but measurement precision and reliability of task coordination data are worsened
Solution Approach 1:
The system pre-assigns joint tasks to autonomous appliances before execution. The server computer determines task allocation in advance, and RFID tags are pre-configured with task-related information. This preliminary action allows passive RFID tags to provide sufficient coordination data without requiring active power sources, resolving the contradiction between energy savings and data precision.
Solution Approach 2:
The system implements feedback loops where autonomous appliances report task progress and status information back to the server computer via RFID communication. The server computer monitors task completion status and adjusts task allocation based on feedback from appliances. This feedback mechanism ensures reliable task coordination using passive RFID tags, maintaining data precision while minimizing energy consumption.
2Device complexity
If passive RFID tags are used for autonomous appliance communication, then device complexity is reduced, but reliability of peer-to-peer cybernetic control is worsened
Solution Approach 1:
The server computer acts as an intermediary between autonomous appliances, coordinating task allocation and monitoring task completion. Instead of requiring direct peer-to-peer communication between appliances, the server computer mediates all control decisions. This intermediary approach simplifies the overall system architecture while maintaining reliable control through centralized coordination using passive RFID tags.
Solution Approach 2:
The passive RFID tags serve multiple functions: identification, task information storage, and communication medium between appliances and the server computer. This multi-functionality reduces device complexity by eliminating the need for separate active communication modules while maintaining reliable control through the universal RFID interface.
3Productivity
If RFID tag readers are integrated into autonomous appliances, then task coordination efficiency is improved, but device complexity and manufacturing cost are worsened
Solution Approach 1:
Autonomous appliances autonomously read RFID tags and report task completion status without requiring complex integrated communication systems. The appliances use simple RFID readers to retrieve task information from tags and report back to the server computer. This self-service approach improves task coordination efficiency while minimizing appliance complexity by leveraging the existing RFID infrastructure.
