Solution Overview
Problem
Existing solid detergent compositions using hydratable alkaline components face challenges in incorporating high levels of surfactants due to incompatibility, leading to component separation issues in liquid forms and limited chemical activity in commercial vehicle washing applications.
Innovation Solution
A solid detergent composition is developed with a hydratable alkaline component, surfactant, and viscosity control component, solidified through a hydration reaction, allowing for a high concentration of cleaning agents without component separation, and can be easily converted to a liquid detergent composition for use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If liquid detergent compositions are used to provide high chemical activity, then cleaning effectiveness is improved, but component separation occurs and hydrotrope chemicals are required
Solution Approach 1:
The invention changes the physical state parameter from liquid to solid, allowing the detergent to achieve high chemical activity levels without component separation. The solid form enables higher surfactant concentrations while maintaining stability, eliminating the need for hydrotrope chemicals that are typically required in liquid formulations to prevent separation.
Solution Approach 2:
The invention creates a composite solid detergent composition combining hydratable alkaline components, surfactants, and viscosity control components in specific proportions. This composite structure allows the material to maintain high chemical activity while preventing component separation, achieving both reliability and stability simultaneously.
2Stability of the object's composition
If solid detergent compositions are used to avoid component separation, then stability is improved, but chemical activity level is limited
Solution Approach 1:
The invention utilizes the parameter change from liquid to solid state to achieve both stability and high chemical activity. The solid form prevents component separation while the hydratable alkaline components maintain high chemical activity levels, reversing the conventional trade-off between stability and activity.
Solution Approach 2:
The invention creates a solid detergent composition that replicates the high chemical activity characteristics of liquid detergents while adding the stability benefit of the solid state. The solid composition can be dissolved or degraded in water to produce liquid detergent formulations, copying the effective properties of liquids without their instability issues.
3Reliability
If high levels of surfactant are incorporated into solid detergent, then cleaning effectiveness is improved, but component separation occurs in liquid form
Solution Approach 1:
The invention changes the physical state from liquid to solid, enabling the incorporation of high levels of surfactant without causing component separation. The solid form provides the stability needed to maintain high surfactant concentrations, while the hydratable alkaline components ensure cleaning effectiveness when the solid is subsequently dissolved or degraded in water.
