Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional laundry liquid compositions are used, then standard cleaning performance is achieved, but high viscosity results in difficult processing and high energy consumption during manufacture
Solution Approach 1:
The patent changes the chemical parameters of the composition by incorporating an alkoxylated zwitterionic polyamine polymer with specific molecular weight (5,000-50,000 Da) and charge density (1-10 mmol/g), which fundamentally alters the viscosity profile of the laundry liquid from high to low, enabling easier processing and reduced energy consumption during manufacture
Solution Approach 2:
The patent creates a composite system by combining the alkoxylated zwitterionic polyamine polymer with conventional surfactants and enzymes, where the polymer acts as a viscosity-modifying agent that maintains cleaning effectiveness while reducing overall composition viscosity, thereby improving manufacturability without sacrificing performance
2Ease of manufacture
If conventional laundry liquid compositions are used, then standard cleaning performance is achieved, but high viscosity results in high energy consumption during manufacture
Solution Approach 1:
The patent modifies the physical parameter of viscosity through the use of alkoxylated zwitterionic polyamine polymer, which reduces the energy required for mixing, heating, and processing during manufacture, directly addressing the energy consumption issue while maintaining cleaning efficacy
3Ease of manufacture
If alkoxylated zwitterionic polyamine polymer is added to reduce viscosity, then easier processing and reduced energy consumption are achieved, but composition complexity increases
Solution Approach 1:
The alkoxylated zwitterionic polyamine polymer serves multiple functions simultaneously: it acts as a viscosity reducer, a cleaning booster, and a fabric protectant, thereby reducing composition complexity despite the addition of a new component, as one ingredient performs multiple roles that would otherwise require separate additives
