Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Concentrated hard surface treatment compositions stored in water-soluble containers face degradation and leakage issues at high temperatures, leading to premature failure and undesirable leakage, which affects their stability and consumer acceptance.
Innovation Solution
A dilutable concentrated hard surface treatment composition with a detersive anionic surfactant in acid form reacting with alkanolamine, a dual-solvent system of propylene glycol phenyl ether and dipropylene glycol n-butyl ether, and an organic acid like lactic acid, which maintains stability and prevents leakage when stored in water-soluble containers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If concentrated hard surface treatment composition is stored in water-soluble containers at high temperatures, then the container dissolves and releases the composition, but the composition degrades and leaks prematurely
Solution Approach 1:
The patent changes the chemical parameters of the composition by using an acid-form surfactant that reacts with alkanolamine only upon dissolution in water. This parameter change allows the composition to remain stable during storage in water-soluble containers at high temperatures, preventing premature degradation and leakage, while ensuring the cleaning reaction occurs only when needed after dilution.
2Ease of operation
If concentrated hard surface treatment composition is stored in water-soluble containers, then it is convenient for consumer use, but it suffers leakage and premature failure during long-term storage
Solution Approach 1:
The patent applies preliminary action by pre-packaging the acid-form surfactant and alkanolamine in separate compartments within the water-soluble container. The container is designed to dissolve and release the composition only when placed in water by the consumer, ensuring the composition remains stable during long-term storage while providing convenient consumer use.
3Object-generated harmful factors
If conventional concentrated hard surface treatment composition is used, then it provides cleaning action, but it degrades at high temperatures causing leakage
Solution Approach 1:
The patent uses a composite material approach by combining an acid-form surfactant with alkanolamine in a water-soluble container system. This composite structure maintains thermal stability during storage while providing effective cleaning action when the components are released and mixed in water, resolving the contradiction between cleaning efficacy and thermal stability.
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 composition remains stable at high temperatures, preventing leakage and ensuring effective dilution into a ready-to-use form without water addition, providing excellent cleaning performance and antimicrobial efficacy.
Implementation Method 1
a detersive anionic surfactant in acid form, such that the detersive anionic surfactant in acid form reacts with an alkanolamine present in the concentrated hard surface cleaning compositions to form an alkanolamine form of the detersive anionic surfactant
Implementation Method 2
such unit dosage forms of the concentrated hard surface treatment compositions are provided into a larger volume of water, which degrades or dissolved the at least partially water soluble container, releasing the concentrated hard surface treatment composition to the water
