Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaner compositions for pump foamer containers often clog due to high molecular weight cation polymers, compromising foam resilience and persistence, and unsatisfactory washing feel.
Innovation Solution
Incorporating a soap neutralized with sodium N-methyltaurate and a polymer with dimethyl diallyl ammonium chloride as a monomer unit, with a molecular weight of 200,000 or less, to prevent clogging and enhance foam resilience and persistence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a cation polymer with large molecular weight is included in the cleaner to impart resilience and persistence to the foam, then the foam resilience and persistence are improved, but clogging is likely to occur in the porous film or passage
Solution Approach 1:
The patent applies parameter changes by precisely controlling the molecular weight of the cation polymer to be 200,000 or less. This parameter optimization allows the polymer to provide sufficient foam resilience and persistence while preventing clogging in the porous film or passage, thereby resolving the contradiction between foam duration and clogging resistance
Solution Approach 2:
The patent uses a composite approach by combining a specific cation polymer (with controlled molecular weight) and a soap obtained by neutralizing a higher fatty acid with sodium N-methyltaurate. This composite formulation synergistically provides both foam resilience/persistence and clogging prevention, addressing the technical contradiction
2Duration of action of moving object
If a cation polymer is included in the cleaner to improve foam resilience, then the foam resilience is improved, but the feeling after washing off is not satisfactory
Solution Approach 1:
The patent optimizes the molecular weight parameter of the cation polymer to 200,000 or less, which balances foam resilience with acceptable washing feel. This parameter control ensures that the polymer provides sufficient foam stability without creating a rough or uncomfortable sensation after washing
Solution Approach 2:
The patent formulates a composite cleaner system combining the optimized cation polymer with a specifically prepared soap (from neutralizing higher fatty acid with sodium N-methyltaurate). This composite formulation achieves both foam resilience and satisfactory washing feel by leveraging the complementary properties of both components
3Ease of manufacture
If a soap obtained by neutralizing a higher fatty acid with conventional neutralizing agents is used, then the cleaning function is provided, but sufficient foam resilience cannot be obtained
Solution Approach 1:
The patent changes the chemical parameter of the neutralizing agent from conventional agents to sodium N-methyltaurate. This chemical substitution produces a soap with superior foam resilience while maintaining effective cleaning function, resolving the contradiction between ease of manufacture and foam performance
Solution Approach 2:
The patent employs a specialized neutralizing agent (sodium N-methyltaurate) that may be less conventional but provides superior performance. This approach prioritizes functional effectiveness over manufacturing simplicity, achieving sufficient foam resilience that justifies the specialized chemical process
