Solution Overview

Problem

Existing methods for demonstrating the cleaning performance of cleaning products, such as dish detergents, are unreliable and non-repetitive due to the variability of grease and water compositions, making it difficult to consistently show the effectiveness of cleaning products to consumers.

Innovation Solution

A method involving a homogenous dairy-based solution and an oil composition, with a specific ratio and temperature, is used to create a visibly even oil dispersion on a demonstration surface, allowing for the effective addition and demonstration of a cleaning composition's ability to remove oil, which can be easily replicated and observed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If grease and water are used in demonstration methods, then the demonstration is representative of real-world grease conditions, but the results become highly variable and unreliable

Engineering Contradiction:

Improverepresentativeness of grease conditionsVSAvoidreliability and repeatability of results

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent changes the chemical composition parameters of the soiling agent from variable natural grease to a controlled mixture of surfactant, oil, and water with specific ratios. This standardization of chemical parameters eliminates variability while maintaining cleaning challenge representativeness, directly resolving the contradiction between adaptability and reliability.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite soiling agent by combining surfactant, oil, and water in specific proportions. This composite material provides consistent and reproducible soiling characteristics while maintaining relevance to real-world cleaning challenges, thereby achieving both representativeness and reliability.

Inventive Principle:

Principle #40Composite materials

2Reliability

If a homogenous dairy-based solution with specific oil ratio is used, then reliable and repeatable results are achieved, but the composition becomes less representative of variable real-world grease

Engineering Contradiction:

Improvereliability and repeatability of resultsVSAvoidrepresentativeness of grease conditions

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent optimizes the oil-to-dairy solution ratio to fall within a specific range (about 1:2.2 to less than about 1:44). This parameter control ensures consistent oil dispersion and film formation, achieving reliability while the oil composition maintains representativeness of greasy soiling conditions.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent creates a uniform distribution of oil within the dairy-based solution, ensuring consistent local properties throughout the soiling agent. This homogeneity at the local level guarantees repeatable results while the overall composition remains representative of greasy conditions.

Inventive Principle:

Principle #3Local quality

3Stability of the object's composition

If oil composition is allowed to disperse for longer time, then even oil dispersion is formed, but the demonstration time increases

Engineering Contradiction:

Improveevenness of oil dispersionVSAvoidwait time for dispersion

Core Design Contradiction:

Stability of the object's compositionVSLoss of time

Solution Approach 1:

The patent specifies an optimal waiting time range (about 1 minute to about 15 minutes) for oil dispersion. Within this time frame, the oil achieves sufficient dispersion and film formation on the demonstration surface without requiring excessive waiting time, balancing composition stability with demonstration efficiency.

Inventive Principle:

Principle #35Parameter changes

AI summary

A method of demonstrating the cleaning performance of a cleaning composition comprises the steps of: providing a homogenous dairy-based solution on a demonstration surface; distributing oil composition on the homogenous dairy based solution to produce an oil dispersion on the demonstration surface; adding a cleaning composition onto the oil dispersion to view the displacement of the oil composition.
