Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern cleaning compositions face challenges in providing excellent cleaning performance, especially in automatic dishwashing formulations, where they struggle with spotting, filming, and fatty residue accumulation, while also needing to be environmentally friendly and effective in hard water conditions.
Innovation Solution
The use of a cleaning composition containing alkali metal salts of methyl glycine diacetic acid (MGDA) and citric acid, combined with glycine or alanine, in specific weight ratios, along with additional components like surfactants and bleaching agents, to enhance cleaning efficacy and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cleaning compositions are used, then cleaning performance is achieved, but fatty residues accumulate in filters and sieves
Solution Approach 1:
The patent converts the harmful effect of fatty residues by using specific chelating agents (MGDA, GLDA, citric acid) in combination with amino acids (glycine, alanine) that transform the deposition problem into effective soil removal. The chelating agents bind metal ions that would otherwise promote fatty residue adhesion, while amino acids provide emulsifying and dispersing effects that prevent residue accumulation in filters.
Solution Approach 2:
The invention uses a composite system combining multiple chelating agents (MGDA, GLDA, citric acid) with amino acids (glycine, alanine) in specific weight ratios. This composite approach creates synergistic effects where the chelating agents address metal ion binding while amino acids provide additional cleaning and anti-deposition properties, effectively preventing fatty residue accumulation while maintaining cleaning performance.
2Reliability
If cleaning compositions are designed for excellent cleaning performance, then spotting and filming are reduced, but environmental friendliness may be compromised
Solution Approach 1:
The patent changes the chemical parameters by using biodegradable chelating agents (MGDA, GLDA, citric acid) instead of traditional non-biodegradable alternatives like EDTA. These agents maintain effective metal ion binding capabilities for spotting and filming prevention while being environmentally friendly and readily biodegradable, thus resolving the contradiction between cleaning performance and environmental impact.
Solution Approach 2:
The invention employs readily biodegradable chelating agents that break down quickly in the environment, effectively treating them as short-living substances that perform their cleaning function and then decompose without persistent environmental harm. This approach maintains cleaning efficacy while minimizing long-term environmental impact.
3Reliability
If cleaning compositions work in hard water conditions, then cleaning effectiveness is maintained, but chelating agent stability may be reduced
Solution Approach 1:
The patent creates a composite system where multiple chelating agents (MGDA, GLDA, citric acid) work together with amino acids (glycine, alanine). This combination provides enhanced stability in hard water conditions through synergistic metal ion binding, where the amino acids supplement the chelating agents' stability while maintaining effectiveness in calcium and magnesium presence.
4Object-affected harmful factors
If filters are cleaned frequently to remove fatty residues, then hygiene is improved, but productivity is reduced
Solution Approach 1:
The patent converts the harmful fatty residue deposition into a beneficial effect by using chelating agents and amino acids that actively prevent residue adhesion to filter surfaces. The chemical composition transforms the filter from a site of harmful accumulation to one that remains clean, reducing maintenance frequency while improving hygiene through the cleaning action of the composition itself.
