Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an aqueous solution comprising an active component is supplied into a detergent composition, then the active component can be delivered effectively, but the stability of the detergent composition is compromised and powder clumping occurs
Solution Approach 1:
The patent changes the physical state of the active component from aqueous solution to granular solid form. This parameter change eliminates the water content that causes instability and clumping, while the granular formulation ensures controlled release and effective delivery of the active component during the wash cycle.
Solution Approach 2:
The patent creates a composite granular material combining the active component with detergent composition materials in a dry state. This composite structure maintains stability during storage and handling, while releasing the active component effectively during use, resolving the contradiction between stability and delivery.
2Quantity of substance
If an aqueous solution comprising an active component is used, then the active component can be supplied, but packaging stability is compromised and leakage occurs
Solution Approach 1:
The patent transforms the active component from liquid aqueous solution form to solid granular form. This parameter change eliminates the流动性 that causes packaging leakage, while maintaining the ability to supply the required quantity of active component through the stable packaging during storage and transport.
3Object-affected harmful factors
If a low dosage level of active component is used, then environmental impact is reduced, but uneven distribution across individual products occurs
Solution Approach 1:
The patent changes the physical form to granular material with controlled particle size and flow properties. This parameter change enables uniform distribution of low dosage levels across individual detergent products during manufacturing, while maintaining low environmental impact through reduced active component concentration.
4Productivity
If conventional detergent compositions are used, then cleaning performance is achieved, but glass corrosion occurs under alkaline conditions
Solution Approach 1:
The patent introduces a cationic polymer as an intermediary substance that forms a protective layer on glass surfaces. This mediator prevents direct contact between the alkaline detergent environment and the glass, reducing corrosion while allowing the detergent to maintain its cleaning performance through the builder and surfactant components.
