Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional thickeners are used in acidic cleaning compositions with abrasive particles, then the composition can maintain viscosity and cleaning performance, but storage stability deteriorates and abrasive particles become non-homogeneously distributed
Solution Approach 1:
The patent changes the chemical parameters of the thickening agent by selecting specific polysaccharides (xanthan gum with specific molecular weight range of 2-15×10^6, guar gum with molecular weight range of 10^5-10^6) and controlling their concentration (0.01-5% by weight), thereby achieving both storage stability and homogeneous abrasive distribution
Solution Approach 2:
The patent uses composite thickening systems by combining different polysaccharides (xanthan gum and/or guar gum with other thickeners like carboxymethyl cellulose, hydroxyethyl cellulose, or alginates) to achieve synergistic effects that simultaneously improve storage stability and abrasive particle distribution
2Stability of the object's composition
If the composition maintains high viscosity for stability, then storage stability improves, but release properties of acidic component and surfactant worsen
Solution Approach 1:
The patent exploits the dynamic rheological properties of polysaccharide thickeners that exhibit shear-thinning behavior, maintaining high viscosity at rest for stability while reducing viscosity under shear stress during application to enable proper release and spreading of the acidic component and surfactant
Solution Approach 2:
The patent optimizes the concentration of polysaccharide thickeners (0.01-5% by weight) and adjusts molecular weight parameters to achieve the right balance between viscosity for stability and fluidity for release properties
3Reliability
If biodegradable thickeners are used to be cost-effective and environmentally friendly, then environmental compatibility improves, but achieving adequate thickening performance and stability becomes more difficult
Solution Approach 1:
The patent selects biodegradable polysaccharides with specific molecular weight ranges (xanthan gum: 2-15×10^6, guar gum: 10^5-10^6) and optimizes their concentration (0.01-5% by weight) to achieve adequate thickening performance while maintaining environmental compatibility
Solution Approach 2:
The patent combines biodegradable polysaccharides (xanthan gum and/or guar gum) with other compatible thickeners to create composite systems that enhance thickening performance and stability while maintaining biodegradability and environmental friendliness
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 achieves good storage stability and cleaning performance by maintaining the acidic component and surfactant release, while being cost-effective and biodegradable, suitable for bathroom and toilet cleaning.
Implementation Method 1
the aqueous compositions in general comprise a thickener. This is especially important when the cleaners are employed in lavatory cleaning since, e.g., toilets, have inclined surfaces which impede the cleaner to stay at the place to be cleaned due to gravity
Implementation Method 2
In order to ensure satisfactory cleaning it is necessary to ensure that the cleaner stays at the surface initially applied and can work there for a certain period. Especially for limescale removal, the cleaner should be able to work for a certain time
Implementation Method 3
an acidic constituent which comprises either citric acid alone or citric acid in combination with an acid selected from the group consisting of sorbic acid, acetic acid, boric acid, formic acid, maleic acid, adipic acid, lactic acid, malic acid, malonic acid, glycolic acid, and mixtures thereof
