A water-soluble powder detergent is developed, which can be mixed on-site with a polar solvent to create customized liquid detergent solutions with optimal concentrations for specific applications, reducing plastic packaging and transport volumes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If liquid detergent is concentrated to reduce packaging and transportation costs, then the concentration and stability of the detergent improve, but the detergent tends to separate into oil and water phases
Solution Approach 1:
A specific salt is introduced as an intermediary substance to mediate between the oil phase and water phase. This salt acts as a bridging agent that facilitates interaction between the hydrophobic oil components and hydrophilic water components, preventing phase separation while maintaining high concentration. The salt concentration is controlled within 5-20% of the total composition to achieve optimal stabilization.
Solution Approach 2:
The patent changes the concentration parameters of both the detergent components and the added salt to achieve a stable high-concentration formulation. By optimizing the salt concentration within a specific range (5-20%) and adjusting the detergent component ratios, the system maintains phase stability at high concentrations that would otherwise cause separation.
2Stability of the object's composition
If salt is added to prevent detergent separation, then the stability of the detergent improves, but excessive salt causes irritation to skin and eyes
Solution Approach 1:
The salt concentration is precisely controlled within the range of 5-20% of the total composition. This parameter optimization ensures sufficient salt is present to stabilize the detergent formulation and prevent phase separation, while remaining below the threshold that causes irritation to skin and eyes. This quantitative control resolves the contradiction between stability and safety.
3Ease of manufacture
If conventional detergents are diluted for use, then they can effectively clean, but they require large amounts of water and generate extensive foam
Solution Approach 1:
The invention changes the concentration parameter of the detergent formulation, creating a highly concentrated product that requires minimal dilution for effective use. This high-concentration formulation maintains cleaning effectiveness while significantly reducing the amount of water needed compared to conventional diluted detergents.
Solution Approach 2:
The formulation extracts and eliminates excessive foam generation from the detergent system while retaining cleaning effectiveness. By carefully selecting and balancing the detergent components and salt concentration, the patent achieves a formulation that cleans effectively without producing the extensive foam characteristic of conventional detergents.
