Engineering Contradiction Analysis
1Productivity
If traditional Body-on-a-chip systems are used for compound evaluation, then individual compound testing can be performed, but high-throughput screening of multiple compounds simultaneously cannot be achieved
Solution Approach 1:
The system divides the culture platform into multiple independent culture chambers (e.g., 6 chambers) that can be independently controlled and evaluated. Each chamber can hold different organ models and test different compounds simultaneously, enabling high-throughput screening while maintaining manageable system complexity through modular design
Solution Approach 2:
The pressure control system serves multiple functions: it can apply pressure to individual chambers, to groups of chambers, or to all chambers simultaneously. The same pneumatic network infrastructure supports both single-compound detailed studies and multi-compound high-throughput screening, making the system versatile for different experimental needs
2Adaptability or versatility
If multiple culture chambers are connected for organ model communication, then phenomena relating to multiple organs can be evaluated, but efficient circulation of liquid culture media between chambers becomes difficult
Solution Approach 1:
The system uses pneumatic pressure control to drive liquid culture media through communication channels connecting multiple culture chambers. By applying pressure differentials between chambers, the system efficiently circulates media without requiring complex mechanical pumps in each chamber, simplifying operation while enabling multi-organ phenomenon evaluation
Solution Approach 2:
The pressure applied to each culture chamber can be dynamically adjusted and changed over time. The system can switch between different pressure configurations to control media flow direction and rate, allowing flexible adaptation to different experimental requirements for multi-organ communication studies
