Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning compositions face issues with environmental safety, cleaning efficacy, and regeneration efficiency due to high water content, clouded states, and the use of high-boiling point components that lead to energy-intensive regeneration and decomposition, as well as poor drying abilities.
Innovation Solution
A liquid concentrate for cleaning compositions is developed, comprising a hydrophobic organic solvent and a hydrophilic amine solvent with specific boiling points and solubility ranges, which forms a uniform solution before adding water, creating a clouded state that enhances cleaning properties and regeneration efficiency while allowing for easy drying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cleaning composition includes benzyl alcohol as an essential component to achieve a clouded state with high water content, then environmental safety and cleaning properties are improved, but regeneration efficiency deteriorates due to high energy requirements and incomplete distillation
Solution Approach 1:
The patent changes the boiling point parameter of the organic solvent from high (benzyl alcohol at 205°C) to moderate (140-190°C range), enabling effective fractional distillation while maintaining cleaning composition performance. This parameter optimization allows regeneration at lower temperatures with complete solvent recovery.
Solution Approach 2:
The patent extracts benzyl alcohol from the essential components and replaces it with organic solvents having moderate boiling points. This extraction eliminates the regeneration problem caused by high-boiling point components while preserving the clouded state and cleaning properties through alternative solvent selection.
2Productivity
If the heating temperature is increased to regenerate the cleaning composition by fractional distillation, then regeneration speed is improved, but decomposition of constituent components occurs leading to decreased cleaning properties
Solution Approach 1:
The patent optimizes the boiling point parameter of the organic solvent to 140-190°C, which enables fractional distillation to proceed at moderate temperatures. This temperature optimization prevents thermal decomposition of cleaning composition components while maintaining efficient regeneration throughput.
3Reliability
If an organic solvent with high boiling point is used to achieve excellent cleaning properties, then cleaning efficacy is improved, but drying ability deteriorates and additional rinsing steps are required
Solution Approach 1:
The patent optimizes the boiling point parameter of the organic solvent to a moderate range (140-190°C), which provides optimal balance between cleaning efficacy and drying ability. This parameter optimization allows the cleaning composition to evaporate completely without residue, eliminating the need for additional rinsing steps while maintaining excellent cleaning performance.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution achieves excellent environmental safety, cleaning efficacy, and regeneration efficiency by forming a stable clouded state with added water, reducing energy requirements and preventing decomposition, and enabling efficient drying without additional rinsing steps.
Implementation Method 1
the cleaning composition disclosed in Patent Document 1 has a problem that the water content is relatively small, and the environmental safety is insufficient. Furthermore, there is no intention of making it possible to enhance the cleaning properties effectively, even in the case where a relatively large water content is employed, by bringing the cleaning composition to a clouded state (emulsion state).
Implementation Method 2
there is also a problem that when it is attempted to regenerate a cleaning composition that has been used, by fractional distillation, the ester compound which is an essential component undergoes hydrolysis, and a decrease occurs in the cleaning properties of the cleaning composition after regeneration
Implementation Method 3
when it is attempted to regenerate a cleaning composition that has been used, by fractional distillation
