Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single flow channel is used for nucleic acid synthesis, then the structure is simple, but the flow velocity distribution becomes excessively concentrated and higher reaction equivalents are required
Solution Approach 1:
The single flow channel is segmented into multiple flow channels by introducing alternating first and second helical blades. This segmentation distributes the fluid flow across multiple paths, preventing excessive concentration of flow velocity in a single channel while maintaining overall structural simplicity.
Solution Approach 2:
The helical blades extend in different helical directions (first and second helical directions) from the axis toward the inner wall, adding a dimensional aspect to the flow channel structure. This dimensional change creates alternating flow paths that distribute velocity more uniformly without significantly increasing structural complexity.
2Device complexity
If a single flow channel is used for nucleic acid synthesis, then the structure is simple, but the costs increase due to higher reaction equivalent requirements
Solution Approach 1:
By segmenting the single flow channel into multiple flow channels using alternating helical blades, the system distributes the reaction equivalents across multiple paths. This reduces the concentration of reactants required in any single channel, thereby lowering the overall reaction equivalent demand while keeping the structural addition minimal.
Solution Approach 2:
The alternating first and second helical blades create local variations in flow characteristics within different regions of the column. This local quality differentiation ensures that reaction equivalents are distributed more efficiently across different spatial zones, reducing the total quantity needed while maintaining effective synthesis conditions.
3Device complexity
If a single flow channel is used, then the structure is simple, but the flow velocity distribution becomes excessively concentrated
Solution Approach 1:
The single flow channel is divided into multiple flow channels by alternating helical blades, which segments the velocity distribution across multiple paths. This prevents excessive concentration of flow velocity in one location while maintaining a relatively simple structural addition to the original single-channel design.
Solution Approach 2:
The helical blades extend in different helical directions from the axis toward the inner wall, creating flow paths that distribute velocity in multiple dimensional directions. This dimensional approach to flow channel creation ensures uniform velocity distribution without requiring complex multi-dimensional structural modifications.
4Productivity
If higher reaction equivalents are introduced, then the synthesis can proceed, but the costs increase and yields decrease
Solution Approach 1:
Segmenting the flow into multiple channels allows the same reaction equivalents to be distributed more effectively, improving the utilization efficiency of each unit of reactant. This segmentation enables higher yields without proportionally increasing the quantity of reaction equivalents required, as each channel operates more efficiently with its allocated share.
Solution Approach 2:
The alternating helical blades create different flow velocity distributions and residence time patterns in different channels, effectively changing the kinetic parameters of the reaction environment. This parameter variation allows for more efficient reaction progression, improving yields without requiring higher reaction equivalents.

AI summary
A synthetic column for nucleic acid synthesis includes a column body, first helical blades, and second helical blades. The column body has an axis, an inner wall, and an inlet end and an outlet end opposite to each other. The first helical blades helically extend in a first helical direction from the axis toward the inner wall. Two ends of each first helical blade are connected to the axis and the inner wall. The second helical blades helically extend in a second helical direction from the inner wall toward the axis. The first helical direction is different from the second helical direction. The first and second helical blades are arranged in an alternating manner. One end of each second helical blade is connected to the inner wall, and the other end has a second helical side gradually approaching the axis from the inlet end toward the outlet end.
