Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If guar protein extract is chemically modified by grafting chemical groups, then hair and skin conditioning properties are improved, but product complexity increases

Engineering Contradiction:

Improveconditioning propertiesVSAvoidproduct complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by chemically modifying the guar protein extract through grafting of chemical groups (such as cationic groups) onto the protein structure. This chemical modification transforms the base guar protein into derivatives with enhanced conditioning properties while maintaining the fundamental protein structure, thereby improving performance without excessive complexity

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The invention creates composite materials by combining guar protein with grafted chemical groups to form modified protein extracts. These composite structures integrate the natural protein framework with additional functional groups, achieving superior conditioning effects through the synergistic combination of natural and modified properties

Inventive Principle:

Principle #40Composite materials

2Adaptability or versatility

If guar protein extract is used in cosmetic compositions, then compatibility with anionic surfactants is improved, but formulation complexity increases

Engineering Contradiction:

Improvecompatibility with anionic surfactantsVSAvoidformulation complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent modifies the electrical charge parameters of guar protein by grafting cationic groups, transforming it from a neutral or anionic protein to a cationic derivative. This parameter change enables electrostatic compatibility and synergistic interactions with anionic surfactants, expanding formulation versatility while maintaining relatively simple composition structures

Inventive Principle:

Principle #35Parameter changes

3Reliability

If phytosanitary formulations are applied to plants, then treatment effectiveness is improved, but drop rebound and runoff increase

Engineering Contradiction:

Improvetreatment effectivenessVSAvoiddrop rebound and runoff

Core Design Contradiction:

ReliabilityVSLoss of substance

Solution Approach 1:

The patent introduces modified guar protein extract as an intermediary adhesion promoter between phytosanitary formulations and plant surfaces. This intermediary substance acts as a bridge that enhances droplet attachment to leaves and stems, reducing rebound and runoff while maintaining the bioactive ingredients' effectiveness. The protein extract serves as a mediator that facilitates better contact between the formulation and target surface

Inventive Principle:

Principle #24Intermediary (Mediator)

4Area of stationary object

If large particle size spray drops are used, then coverage area is improved, but instant adhesion decreases and rebound increases

Engineering Contradiction:

Improvecoverage areaVSAvoidinstant adhesion

Core Design Contradiction:

Area of stationary objectVSReliability

Solution Approach 1:

The modified guar protein extract serves as an intermediary adhesion promoter that compensates for the reduced adhesion of large particle size drops. By incorporating this protein-based mediator into the formulation, large drops maintain their coverage advantage while gaining improved attachment to plant surfaces, effectively decoupling the trade-off between drop size and adhesion

Inventive Principle:

Principle #24Intermediary (Mediator)
