Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If hydrophilic modification of chemical structure is used to improve solubility, then solubility increases, but pharmacological activity decreases
Solution Approach 1:
The compound is segmented into a hydrophobic core (maintaining pharmacological activity) and a hydrophilic shell (providing solubility). The amphiphilic carrier molecules self-assemble with their hydrophobic parts interacting with the core compound and hydrophilic parts facing outward, creating a segmented structure that resolves the contradiction between solubility and activity.
Solution Approach 2:
The amphiphilic carrier acts as an intermediary between the hydrophobic compound and the aqueous environment. It mediates the interaction by providing a hydrophobic interface for the compound while presenting a hydrophilic interface to water, thus improving solubility without modifying the compound's active core structure.
2Quantity of substance
If amphiphilic carriers are used to improve solubility, then solubility increases, but structural stability decreases
Solution Approach 1:
The patent optimizes key parameters including the hydrophobic-hydrophilic balance of the carrier molecules, the concentration ratio of carrier to compound, and the pH of the aqueous environment. These parameter changes enable the formation of stable self-assembled structures that maintain integrity in physiological conditions while providing enhanced solubility.
3Reliability
If compound proportion in carrier particles is increased to improve efficacy, then in vivo efficacy increases, but solubility decreases
Solution Approach 1:
The patent creates local quality differentiation within the particle structure, with a high-concentration core region containing the active compound surrounded by a solubilizing shell of amphiphilic carriers. This allows the compound proportion in the functional core to be high (improving efficacy) while the overall particle maintains solubility through the hydrophilic shell.
