Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional biomolecule-based information storage systems are used, then data storage capacity is achieved, but scalability and automation are insufficient
Solution Approach 1:
The patent replaces traditional mechanical synthesis methods with electrochemical control systems. Addressable electrodes enable precise, automated control of polynucleotide synthesis at each locus through electrical signals, eliminating manual intervention and enabling high-throughput automated production of DNA-based storage media.
Solution Approach 2:
The system changes the control parameter from mechanical operations to electrical parameters. By using addressable electrodes with controllable voltage/current, the system achieves automated, scalable control over synthesis conditions, allowing parallel processing of multiple loci and significantly improved productivity.
2Manufacturing precision
If conventional nucleic acid synthesis methods are used, then polynucleotide production is achieved, but sequence density and turnaround time are suboptimal
Solution Approach 1:
The patent divides the synthesis surface into multiple addressable loci, each capable of independent polynucleotide synthesis. This segmentation allows parallel synthesis of numerous sequences simultaneously, increasing overall throughput and reducing turnaround time while maintaining high sequence density through precise spatial control.
Solution Approach 2:
The system performs preliminary positioning and preparation of reagents at each locus before synthesis begins. Addressable electrodes are pre-configured and reagents are delivered in advance, enabling immediate initiation of synthesis when needed, thus reducing turnaround time without compromising sequence density.
3Ease of manufacture
If manual reagent manipulation is used, then synthesis control is achieved, but reagent utilization efficiency is low
Solution Approach 1:
The patent implements self-service through electrochemical control at addressable loci. The system automatically manages reagent delivery and consumption at each electrode location, eliminating manual manipulation. Reagents are precisely delivered only where and when needed, maximizing utilization efficiency and minimizing waste.
Solution Approach 2:
The system applies local quality control by enabling independent reagent manipulation at each addressable locus. This localized control ensures reagents are delivered precisely where needed, improving utilization efficiency while maintaining easy synthesis control through the addressable electrode array.
4Quantity of substance
If high sequence density is achieved, then storage capacity increases, but synthesis complexity increases
Solution Approach 1:
The patent employs universal addressable electrodes that can control multiple synthesis reactions simultaneously. Each electrode serves multiple functions: controlling reagent delivery, monitoring synthesis progress, and enabling parallel operations across numerous loci. This multi-functionality increases storage capacity through high sequence density while managing system complexity through standardized, reusable components.
