Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the roller is disassembled for processing and reinstalled manually, then the roller can be processed into the required pattern and size, but the axis of the roller may become eccentric due to manual installation errors, reducing printing precision
Solution Approach 1:
The patent combines the roller processing function and roller mounting function into a single integrated device. The processing mechanism directly processes the roller while it remains mounted on the axis, eliminating the need for disassembly and reassembly. This merging of functions ensures that the roller maintains its coaxiality throughout the processing operation, as the roller never leaves the mounted position during processing.
Solution Approach 2:
The integrated device allows the roller to be processed in situ without requiring removal from the mounting axis. The processing mechanism serves the roller directly while it remains in its operational position, making the system self-sufficient and eliminating external intervention that could cause misalignment.
2Ease of manufacture
If the roller is disassembled and reinstalled multiple times for processing, then the roller can be processed, but the installation time increases and printing efficiency decreases
Solution Approach 1:
The patent merges the processing operation with the mounted state of the roller, allowing processing to occur without disassembly. This eliminates the time-consuming cycles of removal and reinstallation, significantly reducing total processing time and improving printing efficiency.
Solution Approach 2:
The roller is processed while already in its final mounted position, performing the processing action before any potential misalignment could occur. This preliminary processing in situ avoids subsequent adjustments and re installations.
3Ease of manufacture
If the roller is manually reinstalled after processing, then the roller can be used for printing, but the roller may vibrate due to inaccurate manual installation, reducing the uniformity of silver nanowires
Solution Approach 1:
The patent combines processing and mounting functions so that the roller remains securely mounted during processing. This eliminates the vibration and misalignment issues that arise from manual reinstallation, as the roller never leaves its mounted position and maintains stable contact with the axis throughout the entire process.
