Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional solvents are used in emulsifiable concentrates, then the active ingredients can be dissolved, but the solvents may have high water solubility or high toxicity

Engineering Contradiction:

Improvesolvency for active ingredientsVSAvoidtoxicity and water solubility

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent modifies the chemical structure of aromatic solvents by introducing specific substituents (R1 and R2 groups) with defined carbon chain lengths and types to optimize the balance between solvency, water solubility, and toxicity. This involves changing molecular parameters to achieve desired properties

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The invention creates composite solvent systems by combining multiple aromatic compounds (formula A and formula B) in specific ratios, where each compound contributes different properties to achieve the optimal balance of solvency, low water solubility, and low toxicity

Inventive Principle:

Principle #40Composite materials

2Reliability

If aromatic solvents with high solvency are used, then active ingredients dissolve effectively, but water solubility may increase

Engineering Contradiction:

ImprovesolvencyVSAvoidwater solubility

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent applies local quality modification by introducing specific substituent groups (R1 and R2) at particular positions on the aromatic ring structure. These local modifications alter the molecular interactions to enhance solvency for active ingredients while maintaining low water solubility through hydrophobic characteristics of the substituent groups

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The invention changes physical-chemical parameters of the solvent molecules by controlling the size, type, and arrangement of substituent groups (R1 and R2) to optimize the balance between solvency capability and water solubility resistance

Inventive Principle:

Principle #35Parameter changes
