Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If amylose derivative is chemically bonded to carrier, then separation performance is improved, but solvent options are limited
Solution Approach 1:
The invention changes the chemical parameters of the carrier surface by introducing specific functional groups (amino, carboxyl, hydroxyl) that can form chemical bonds with the amylose derivative while being compatible with a broader range of solvents. This parameter change allows the system to achieve both strong bonding and solvent versatility.
Solution Approach 2:
The invention creates a composite structure combining the carrier, bonding agent, and amylose derivative into an integrated system. The composite nature allows the bonding interface to be optimized separately from the solvent interaction interface, resolving the contradiction between bonding strength and solvent compatibility.
2Adaptability or versatility
If amylose derivative is physically adsorbed onto carrier, then solvent options are maintained, but separation performance is reduced
Solution Approach 1:
The invention introduces a bonding agent as an intermediary between the carrier and amylose derivative. This intermediary provides chemical bonding functionality while maintaining the solvent compatibility of the original physical adsorption system, thus improving separation performance without sacrificing solvent options.
3Reliability
If chemical bonding is used to support amylose derivative, then stability is improved, but manufacturing complexity increases
Solution Approach 1:
The invention simplifies the manufacturing process by changing the parameter of the carrier surface to include pre-formed functional groups that readily bond with the amylose derivative. This parameter change transforms a complex multi-step bonding process into a simpler, more reliable procedure.
