Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If anionic surfactants are used in cleansing compositions, then washing performance and foam volume are improved, but stability in varying water hardness and temperature conditions deteriorates
Solution Approach 1:
The patent uses a composite surfactant system combining anionic surfactants (internal olefin sulfonate) with amine compounds and alcohols to create a stable composition that maintains both washing performance and stability across varying water conditions. The synergistic combination of multiple surfactant types and conditioning agents resolves the contradiction between effective cleansing and compositional stability.
Solution Approach 2:
The patent optimizes specific parameter ranges including internal olefin sulfonate content (1-20 mass%), amine compound content (0.1-10 mass%), and alcohol content (1-20 mass%) to achieve both high washing performance and stability. By carefully controlling these compositional parameters, the invention maintains reliability while preventing composition deterioration.
2Quantity of substance
If the volume of foam is increased for good washing performance, then washing effectiveness is improved, but stability of the composition deteriorates
Solution Approach 1:
The patent combines anionic surfactants that generate abundant foam with amine compounds and alcohols that stabilize the composition. This composite approach allows the formulation to produce large foam volumes for effective washing while the additional components prevent composition instability that would otherwise result from high surfactant concentrations.
3Reliability
If internal olefin sulfonate content is increased to improve washing performance, then cleansing effectiveness is improved, but stability at high temperatures deteriorates
Solution Approach 1:
The patent limits internal olefin sulfonate content to 1-20 mass% and combines it with specific amounts of amine compounds (0.1-10 mass%) and alcohols (1-20 mass%). This parameter optimization ensures that sufficient surfactant is present for effective cleansing while the balanced formulation maintains thermal stability and prevents composition separation at elevated temperatures.
Solution Approach 2:
The amine compounds and alcohols act as intermediary stabilizing agents that mediate between the anionic surfactant and the aqueous environment. These intermediaries enhance the overall composition stability at high temperatures while allowing the surfactant to maintain its cleansing performance.
