Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If white ink is stored in existing continuous ink supply devices, then the ink can be supplied to the printhead, but the ink is prone to sedimentation and clogging during storage
Solution Approach 1:
The stirring paddle is activated before ink supply to pre-mix the white ink and prevent sedimentation from occurring during storage periods. This preliminary stirring action ensures the ink remains uniform and ready for immediate use without clogging.
Solution Approach 2:
The stirring mechanism operates periodically or continuously during ink storage to maintain constant mixing, preventing the ink from settling and maintaining its homogeneous composition throughout the storage period, thereby ensuring reliable ink supply.
2Stability of the object's composition
If a stirring function is added to prevent ink sedimentation, then ink uniformity is improved, but device complexity increases
Solution Approach 1:
The stirring function is implemented as a separate, modular component within each ink container rather than integrating it into the main supply system. This segmentation allows the stirring mechanism to be added independently without redesigning the entire ink supply device, thus managing complexity.
Solution Approach 2:
The stirring paddle is designed to be self-contained within the ink container, using its own integrated motor and mechanism to perform the mixing function without requiring external control systems or additional complex infrastructure, thereby minimizing overall device complexity.
