Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional batch chromatography is used to purify proteins, then protein purity can be achieved through multiple cycles, but the number of purification cycles increases and productivity decreases
Solution Approach 1:
The patent implements continuous chromatography where the chromatography matrix is continuously loaded with protein mixture and flow-through is continuously collected and re-loaded in a seamless cycle, eliminating the interruptions and multiple discrete batches required in traditional methods to achieve sufficient purity
Solution Approach 2:
The patent pre-establishes a feedback loop where flow-through from each cycle is automatically collected and prepared for re-loading in the next cycle, allowing the system to maintain optimal binding capacity continuously without requiring multiple separate purification steps
2Quantity of substance
If chromatography matrix is loaded to maximum binding capacity in each cycle, then protein recovery increases, but protein loss occurs due to breakthrough and operational complexity increases
Solution Approach 1:
The patent dynamically adjusts the loading capacity parameter of the chromatography matrix based on real-time monitoring of binding capacity, allowing the system to operate at optimal levels that prevent protein loss through breakthrough while maximizing recovery
Solution Approach 2:
The patent incorporates feedback mechanisms to monitor the binding capacity of the chromatography matrix in real-time and adjust the loading parameters accordingly, ensuring that the matrix is loaded to the optimal capacity without exceeding it and causing protein loss
3Manufacturing precision
If multiple purification cycles are performed to achieve sufficient purity, then protein purity improves, but operational speed decreases and time is lost
Solution Approach 1:
The patent establishes a continuous operation mode where the chromatography matrix is continuously loaded, washed, and re-loaded without interruption, eliminating the time losses associated with multiple discrete purification cycles while maintaining high protein purity through consistent feedback-controlled operation
4Manufacturing precision
