Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Formulating a hard surface cleaning composition that balances good cleaning performance with surface shine while maintaining stability over time is challenging, as improvements in one aspect often compromise another.
Innovation Solution
A detergent composition comprising 0.1-10% amine oxide, 0.01-15% nonionic surfactant, and 0.01-15% perfume formulation, with specific weight ratios and pH between 9-14, which includes a mixture of amine oxide, nonionic surfactant, and perfume formulation to provide effective cleaning and shine without stability issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cleaning properties of a composition are improved, then the cleaning performance is enhanced, but the stability of the composition is reduced
Solution Approach 1:
The patent applies parameter changes by optimizing the pH range (9-14) and specific ingredient concentrations (amine oxide 0.1-10%, nonionic surfactant 0.01-15%) to achieve both improved cleaning performance and maintained stability. The weight ratio of amine oxide to nonionic surfactant (3:1 to 10:1) is carefully controlled to balance cleaning efficacy with composition stability over time.
2Reliability
If the cleaning properties of a composition are improved, then the cleaning performance is enhanced, but the shine of the cleaned surface is reduced
Solution Approach 1:
The patent uses a composite material approach by combining amine oxide with nonionic surfactant in specific ratios (3:1 to 10:1). This composite formulation achieves synergistic effects where the amine oxide provides cleaning power while the nonionic surfactant contributes to shine enhancement, resolving the contradiction between cleaning performance and surface appearance.
3Reliability
If a change in the formula leads to a positive effect in one aspect, then that aspect is improved, but a negative effect is induced in another aspect
Solution Approach 1:
The patent applies partial action by using controlled concentrations of active ingredients (amine oxide 0.1-10%, nonionic surfactant 0.01-15%) rather than maximum amounts. This partial formulation approach achieves sufficient cleaning performance while avoiding excessive concentrations that would compromise composition stability, demonstrating the principle of using slightly less than maximum potential dosage.
