Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If polymer strands are synthesized using conventional methods with single monomer addition rounds, then synthesis can be performed with simple procedures, but the number of synthesis rounds increases and reagent consumption increases
Solution Approach 1:
The patent segments the synthesis process by dividing polymer strands into different batches based on their sequence characteristics. Each batch is optimized with specific monomer addition orders, allowing parallel processing of multiple batches with different optimization strategies, thereby reducing total reagent consumption while maintaining procedural simplicity
Solution Approach 2:
The patent implements dynamic monomer addition by determining optimal addition orders based on the specific sequence requirements of each batch. The system adaptively adjusts which monomers are added in each round based on real-time synthesis progress and batch-specific characteristics, minimizing waste without complicating the overall procedure
2Productivity
If the number of polymer strands synthesized exceeds synthesizer capacity, then large-scale production is achieved, but the number of synthesis batches increases and time consumption increases
Solution Approach 1:
The patent performs preliminary analysis of polymer sequences to identify common patterns and characteristics before synthesis begins. This pre-processing allows the system to pre-determine optimal batch groupings and monomer addition orders, enabling parallel processing of multiple batches simultaneously, thus reducing total synthesis time while maintaining high productivity
Solution Approach 2:
The patent ensures continuous utilization of the synthesizer by optimizing batch scheduling and monomer addition sequences. The system minimizes idle time between batches and ensures that each synthesis round contributes maximally to completing multiple polymer strands, maintaining continuous productive action across all batches
3Ease of operation
If monomers are added in fixed sequential orders, then synthesis control is simplified, but unincorporated monomers become waste and synthesis efficiency decreases
Solution Approach 1:
The patent applies different monomer addition orders to different batches based on their specific sequence requirements. Each batch receives a customized addition schedule tailored to its local characteristics, maximizing incorporation efficiency and minimizing waste, while the overall system remains easily controllable through automated batch management
4Ease of manufacture
If batches are grouped without optimization, then batch processing is simple, but the total number of monomer addition steps increases
Solution Approach 1:
The patent performs preliminary optimization of batch groupings by analyzing sequence similarities and common patterns before synthesis begins. This pre-optimization identifies the most efficient batch configurations that minimize total synthesis steps, allowing simple automated execution during the actual synthesis process without requiring complex real-time decision-making

AI summary
The efficiency of polymer synthesis is increased by reducing the number of monomer addition cycles needed to create a set of polymer strands. The number of cycles depends on the sequences of the polymer strands and the order in which each type of monomer is made available for addition to the growing strands. Efficiencies are created by grouping the polymer strands into batches such that all the strands in a batch require a similar number of cycles to synthesize. Efficiencies are also created by selecting an order in which the monomers are made available for addition to the growing polymer strands in a batch. Both techniques can be used together. With these techniques, the number of cycles of monomer addition and commensurate reagent use may be reduced by over 10% as compared to naïve synthesis techniques.
