Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an excessively high concentration of imidazole antifungal drug is used, then the antifungal effect is strengthened, but adverse reactions and cumulative poisoning occur
Solution Approach 1:
The patent introduces a novel solvent system comprising ionic liquid, alcohol organic solvent, and water as intermediaries to carry and deliver the antifungal drug. This solvent system acts as a mediator that enables the drug to reach effective concentrations at the lesion site while preventing direct contact between high-concentration drug and skin, thereby reducing adverse reactions and cumulative poisoning.
Solution Approach 2:
The patent changes the physical and chemical parameters of the drug delivery system by formulating it in a specific solvent system with controlled concentration ranges. The solvent system modifies the drug's solubility, penetration characteristics, and release profile, allowing effective antifungal action at lower drug concentrations while minimizing harmful effects.
2Object-affected harmful factors
If an excessively low concentration of imidazole antifungal drug is used, then adverse reactions are reduced, but the drug fails to reach effective therapeutic concentration at the lesion site
Solution Approach 1:
The novel solvent system serves as an intermediary that enhances drug delivery to the lesion site. The combination of ionic liquid, alcohol organic solvent, and water improves drug solubility and penetration through the skin barrier, enabling low-concentration formulations to achieve effective therapeutic levels at the target site while maintaining safety.
Solution Approach 2:
The patent modifies key parameters of the drug delivery system including solvent composition, drug concentration, and application formulation. These parameter changes optimize the balance between safety and efficacy, allowing low-concentration drug formulations to achieve effective therapeutic outcomes through enhanced delivery mechanisms.
3Ease of operation
If topical imidazole antifungal drugs are applied to treat tinea, then local medication is achieved, but cure rates remain uncertain and recurrence occurs
Solution Approach 1:
The novel solvent system acts as an intermediary that enhances the efficacy of local medication. The ionic liquid, alcohol organic solvent, and water combination improves drug penetration and sustained release at the lesion site, leading to higher cure rates and reduced recurrence while maintaining the advantage of local treatment.
Solution Approach 2:
The patent employs a composite solvent system combining ionic liquid, alcohol organic solvent, and water to create a synergistic delivery platform. This composite formulation enhances drug performance, improves cure rates, and reduces recurrence compared to conventional single-solvent systems, while maintaining ease of local application.

AI summary
An antifungal solution, a preparation method and use thereof are provided, belonging to the technical field of medicine. The antifungal solution includes an antifungal drug and a solvent as raw materials; where the antifungal drug and the solvent are at a mass ratio of (0.1-1):(18-318); and the solvent includes an ionic liquid, an alcohol organic solvent, and water. The ionic liquid has excellent solubility, skin penetration-promoting performance, and antifungal effect; the water can destroy an original polar network of the ionic liquid, forming smaller soluble ion groups, which greatly increase a miscibility window; the alcohol organic solvent can form a cosolvent with the ionic liquid and the water, thereby helping miscibility. The antifungal solution can ensure that the drug in a system is maintained in a dissolved state, thereby improving bioavailability and ensuring better therapeutic effects while reducing dosage.
