Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cutter head is eccentrically mounted and rotatable to enable automatic angle adjustment, then the machine can complete cutting operations, but the cutter head cuts the paper during rotation, leaving extra cutting lines and traces
Solution Approach 1:
The patent applies preliminary action by positioning the cutter head at a specific angle (0 degrees or 360 degrees) before the cutting operation begins. The control system ensures the cutter head is pre-oriented correctly, so that when the machine head moves down to cut, the cutter head is already in the proper orientation and does not rotate during contact with the paper, thereby avoiding extra cutting lines.
2Productivity
If the machine head is lowered to bring the cutter head into contact with the paper after moving to the cutting position, then the cutting operation can be performed, but the cutter head rotates to an appropriate angle during contact, generating uncontrollable forces and extra cutting traces
Solution Approach 1:
The patent applies dynamics by implementing a coordinated control system that dynamically adjusts the cutter head angle based on the machine head's position and movement speed. The control system monitors the machine head's motion and continuously adjusts the cutter head angle to maintain the optimal cutting orientation, preventing unwanted rotation during the cutting process while ensuring smooth and efficient operation.
3Reliability
If the cutter head is controlled to rotate to an appropriate angle during the cutting process, then the cutting can be completed, but the cutter head leaves a small arc cutting line at the front end of the cutting line
Solution Approach 1:
The patent applies feedback by implementing a control system that continuously monitors the cutter head's angle and position during the cutting operation. The system receives real-time feedback about the cutter head's orientation and adjusts it accordingly to maintain the correct cutting angle throughout the process, ensuring straight cutting lines without arc traces at the beginning or end of cuts.
