Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional internal olefin sulfonate formulations are used, then detergent composition can be simplified, but solid matter precipitation and separation occur at low temperatures
Solution Approach 1:
The patent applies parameter changes by precisely controlling the mass ratio of IO-1S to IO-2S isomers within 0.50-4.20, and selecting organic solvents with specific hydroxy group characteristics. This optimization of compositional parameters prevents solid matter precipitation and separation at low temperatures while maintaining formulation simplicity
Solution Approach 2:
The patent creates a composite detergent system by combining internal olefin sulfonate (with controlled isomer ratio) and organic solvent with hydroxy group in specific proportions. This composite approach enhances low-temperature stability through synergistic interaction between components, preventing phase separation while keeping the overall formulation relatively simple
2Reliability
If internal olefin sulfonate with specific isomer ratio is used, then low temperature stability is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent defines a practical parameter range (IO-1S/IO-2S mass ratio of 0.50-4.20) that balances manufacturing feasibility with performance optimization. This range is wide enough to accommodate normal manufacturing variations while still achieving the desired low-temperature stability, thus reducing excessive precision requirements
3Stability of the object's composition
If organic solvent with hydroxy group is added, then solubility and stability are improved, but composition complexity increases
Solution Approach 1:
The organic solvent with hydroxy group acts as an intermediary substance that mediates between the internal olefin sulfonate and water phases. It enhances solubility and prevents separation by forming stable molecular interactions, thereby improving composition stability without requiring complex multi-component systems
