Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional grinding methods are used without data control, then the device complexity is low, but the manufacturing precision of grain size is incorrect and the reliability of the grinding process is poor
Solution Approach 1:
The patent applies preliminary action by storing optimal grinding parameters (grinding time, fineness, power) in advance on RFID chips attached to material packaging. The control unit reads these pre-stored parameters and automatically executes the corresponding grinding program, eliminating the need for manual parameter setting and ensuring consistent grain size precision without requiring complex user intervention.
Solution Approach 2:
The system implements self-service through automatic parameter recognition and process control. The control unit automatically reads material-specific parameters from the RFID chip, selects the appropriate grinding program, and executes the process without human intervention. This self-service mechanism ensures precise grain size control while keeping the device architecture relatively simple.
2Temperature
If manual grinding control is used, then the device complexity is low, but the temperature control is poor leading to overheating and material damage
Solution Approach 1:
The patent implements feedback control by equipping the control unit with sensors that continuously monitor grinding parameters including temperature. The control unit compares actual temperature readings against optimal values stored on the RFID chip and automatically adjusts grinding power and duration to prevent overheating. This closed-loop feedback mechanism ensures proper temperature control without requiring complex manual intervention.
3Reliability
If automated RFID-based control is implemented, then the manufacturing precision and reliability are improved, but the device complexity and cost increase
Solution Approach 1:
The patent uses an RFID chip as an intermediary carrier to store and transmit material-specific grinding parameters. This intermediary approach allows the system to access reliable, pre-tested grinding parameters without requiring complex databases or manual input systems. The RFID chip acts as a simple, reliable interface between the material packaging and the control unit, enhancing reliability while adding minimal complexity.
4Productivity
If grinding parameters are not optimized, then the ease of operation is high, but the productivity and energy efficiency are low
Solution Approach 1:
The system applies preliminary action by pre-calculating and storing optimal grinding parameters (time, power, fineness) for different materials on RFID chips. The control unit automatically retrieves and executes these pre-optimized parameters, ensuring high productivity through efficient grinding cycles while maintaining ease of operation as users simply need to place the material package on the reader without any manual parameter adjustment.
