Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional additive manufacturing machine with one tank and one inkjet head is used, then the device complexity is low, but the productivity is insufficient for manufacturing multi-biomaterial reconstruction models
Solution Approach 1:
The system divides the manufacturing process into multiple independent ink-manufacturing units, each handling a specific biomaterial (bone cement, platelet rich plasma, periodontal stem cells). Each unit has its own tank and inkjet head, allowing parallel deposition of different materials simultaneously, thereby increasing productivity while maintaining manageable complexity through modular design
Solution Approach 2:
The system combines multiple ink-manufacturing units with different biomaterials into a single integrated additive manufacturing system. The multiple inkjet heads are mounted on the same moving mechanism and control unit, enabling them to work cooperatively to deposit complex multi-material structures in one manufacturing cycle, achieving high productivity without proportionally increasing device complexity
2Productivity
If multiple ink-manufacturing units and inkjet heads are used to manufacture multi-biomaterial models, then the productivity increases, but the device complexity increases
Solution Approach 1:
The inkjet head controlling unit and moving mechanism serve multiple functions by controlling all inkjet heads and managing all ink-manufacturing units. This multi-functional design allows the system to handle multiple biomaterials with a unified control architecture, increasing productivity while minimizing the increase in device complexity through shared components
Solution Approach 2:
The system arranges multiple inkjet heads in different spatial positions and orientations, allowing them to deposit materials at different locations and angles simultaneously. This spatial dimensionality enables complex multi-material structures to be built in parallel, significantly increasing output speed while the modular arrangement keeps device complexity manageable
