Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If herbal medicines are used for skin whitening, then whitening activity is improved, but cytotoxicity and skin irritation increase

Engineering Contradiction:

Improvewhitening activityVSAvoidcytotoxicity and skin irritation

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts specific active components from herbal medicines through controlled extraction processes, isolating the beneficial whitening agents while removing toxic substances. This allows the cosmetic composition to contain only the useful components, achieving effective whitening without the cytotoxicity and skin irritation caused by raw herbal medicines.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent employs parameter changes by controlling extraction conditions (temperature, time, solvent concentration) to optimize the extraction of beneficial components while minimizing the extraction of toxic substances. By adjusting these parameters, the composition achieves high whitening activity with reduced cytotoxicity and skin irritation.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If herbal medicines are used at high concentrations for whitening, then whitening effect is improved, but skin irritation increases

Engineering Contradiction:

Improvewhitening effectVSAvoidskin irritation

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts and purifies active components from herbal medicines, creating a concentrated extract that provides strong whitening effects even at low application concentrations. This eliminates the need to use high concentrations of raw herbal medicines that would cause skin irritation.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent uses a controlled extraction process that creates a stable, purified component ready for immediate use in cosmetic formulations. This extracted component maintains its efficacy without requiring high concentrations, thereby avoiding skin irritation while providing effective whitening.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Reliability

If existing whitening cosmetics are used, then whitening activity is achieved, but stability and practical application are poor

Engineering Contradiction:

Improvewhitening activityVSAvoidstability

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent extracts stable, purified active components from herbal medicines through controlled extraction processes. These extracted components are more stable than raw herbal medicines, resisting decomposition and maintaining their whitening activity over time, thereby improving both stability and practical application in cosmetic formulations.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent optimizes extraction parameters (temperature, time, solvent selection) to produce a stable extracted component that maintains its properties under various storage and application conditions. This controlled extraction ensures the component remains stable and effective, overcoming the poor stability of existing whitening cosmetics.

Inventive Principle:

Principle #35Parameter changes
