Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If conventional alkaline cleaning solutions are used, then cleaning power is provided, but excess foam is generated causing rinsing problems and overflows
Solution Approach 1:
The patent changes the chemical parameters of the cleaning solution by incorporating specific foam control compounds (polyether amines and/or polyol ethers) alongside conventional alkaline cleaners. This parameter change allows the solution to maintain high pH cleaning power while simultaneously reducing foam generation through the surfactant properties of the added compounds
Solution Approach 2:
The invention creates a composite cleaning solution by combining conventional alkaline cleaning agents with foam control compounds (polyether amines and/or polyol ethers). This composite formulation achieves both effective metal surface cleaning and reduced foaming, resolving the contradiction between cleaning power and foam control
2Speed
If conventional alkaline cleaners are used, then alkalinity is provided, but quick separation from oil is not achieved
Solution Approach 1:
The patent modifies the chemical composition parameters by adding specific compounds (polyether amines and/or polyol ethers) that alter the separation kinetics. These compounds change the interfacial properties between the cleaning solution and oil, accelerating phase separation while maintaining the alkaline cleaning mechanism intact
3Object-generated harmful factors
If inorganic and organic alkalis are used, then alkalinity is provided, but low foaming and fast oil separation are not achieved
Solution Approach 1:
The patent makes the added compounds (polyether amines and/or polyol ethers) perform multiple functions simultaneously: they act as foam control agents to reduce excessive foaming, and they serve as co-solvents or emulsifiers to accelerate oil separation. This multi-functionality approach adds complexity only once while achieving multiple performance improvements
