Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If water is added to solid washing agents to increase reactivity upon mixing, then reactivity is improved, but storage property and moldability deteriorate
Solution Approach 1:
The patent removes water from the composition entirely, extracting the problematic solvent that caused storage and moldability issues. The invention achieves reactivity through alternative mechanisms (acid-base reaction between citric acid and bicarbonate, enzymatic action) that do not require water as a solvent, thus maintaining storage stability while preserving functional reactivity upon contact with water during use.
Solution Approach 2:
The patent changes the chemical parameters of the washing agent by using powder-form surfactants and incorporating water-soluble polymers that dissolve upon contact with water. This parameter change allows the composition to remain stable in powder form during storage while becoming reactive and functional when water is added during application, resolving the contradiction between storage stability and reactivity.
2Duration of action of moving object
If water is added to solid washing agents to increase reactivity upon mixing, then reactivity is improved, but moldability deteriorates
Solution Approach 1:
The patent removes water from the formulation, extracting the element that prevented moldability. By using a water-free powder composition with appropriate binders and plasticizers, the washing agent can be molded into various shapes and maintains its form during storage, while still achieving reactivity through chemical reactions that occur upon contact with water during use.
Solution Approach 2:
The patent introduces water-soluble polymers and plasticizers as intermediary substances that facilitate moldability during manufacturing. These intermediaries allow the powder composition to be formed into molds and maintain its shape, while the actual reactivity is mediated through acid-base reactions between citric acid and bicarbonate that occur when water is added during application.
3Stability of the object's composition
If minimal water content is used in the composition, then storage property is improved, but reactivity may deteriorate
Solution Approach 1:
The patent changes the chemical parameters by using powder-form surfactants and incorporating water-soluble polymers that remain dormant in powder form but activate upon contact with water. This parameter change allows the composition to maintain storage stability as a dry powder while achieving full reactivity when water is added during application, effectively decoupling storage stability from reactivity.
Solution Approach 2:
The patent performs preliminary action by pre-mixing citric acid and bicarbonate in the powder formulation, which are activated only upon contact with water during use. This preliminary preparation allows the reactive components to be ready for immediate action when water is added, while remaining stable during storage in dry powder form, thus achieving both storage stability and reactivity.
4Ease of operation
If simple molding method is used without water, then ease of operation is improved, but reactivity may deteriorate
Solution Approach 1:
The patent removes water from the molding process, extracting the liquid that complicated the molding operation. By using a water-free powder composition with appropriate binders and plasticizers, the washing agent can be molded into various shapes using simple pressing techniques, while still achieving reactivity through chemical reactions that occur upon contact with water during application.
Solution Approach 2:
The patent introduces water-soluble polymers and plasticizers as intermediary substances that facilitate easy molding without water. These intermediaries act as binders that allow the powder to be formed into molds and maintain its shape during storage, while the actual reactivity is mediated through acid-base reactions between citric acid and bicarbonate that occur when water is added during application.
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 maintains a stable powder form for up to 12 hours and can be molded into desired shapes within minutes without water, ensuring superior storage and moldability while providing uniform dispersibility and foaming properties.
Implementation Method 1
can be molded and solidified in short time by applying slight pressure at room temperature (25 °C) even without adding water
Implementation Method 2
superior compatibility (or dispersibility) is achieved since oleophilic components are uniformly spread on the water surface without aggregation
