Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If 12-hydroxystearic acid is used as a thickening/stabilizing agent, then the fluid organic substance can be brought into a completely solidified state or remain in a liquid state, but the degree of gelatinization cannot be adjusted to achieve a desired viscosity

Engineering Contradiction:
Improvestabilizing effectVSAvoidadjustability of viscosity
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The invention divides the thickening agent into two distinct compounds with different structures (Formula i and Formula ii) that work synergistically. Compound (i) with C12-C18 aliphatic hydrocarbon groups provides strong thickening effect, while compound (ii) with C4-C10 aliphatic hydrocarbon groups provides gelatinizing effect. By segmenting the function between two compounds, the system achieves both reliable stabilization and adjustable viscosity through ratio control.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention changes the parameter of compound composition from a single substance to a two-component system with variable ratios. By adjusting the ratio of compound (i) to compound (ii) from 95:5 to 25:75, the viscosity and gelatinization degree can be continuously tuned. This parameter change approach transforms a binary outcome (solid/liquid) into a continuous spectrum of desired viscosities.

Principle #35Parameter changes

2Ease of manufacture

If a single thickening compound is used, then the formulation is simple, but sufficient thickening/stabilizing effects cannot be achieved

Engineering Contradiction:
Improveformulation simplicityVSAvoidthickening effect
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The invention merges two compounds with complementary properties into a single thickening/stabilizing system. Compound (i) containing C12-C18 aliphatic hydrocarbon groups and compound (ii) containing C4-C10 aliphatic hydrocarbon groups are combined in specific ratios to achieve synergistic thickening and stabilizing effects that exceed the sum of individual contributions.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The invention creates a composite thickening agent system consisting of two distinct chemical compounds with different molecular structures and properties. This composite approach allows the system to exhibit enhanced and tunable thickening, gelatinizing, and stabilizing effects that cannot be achieved with either compound alone.

Inventive Principle:
Principle #40Composite materials

3Reliability

If the thickening agent causes complete solidification, then maximum stabilization is achieved, but the composition loses fluidity and usability

Engineering Contradiction:

Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The invention introduces dynamics into the system by enabling continuous adjustment of the thickening degree through ratio modification. The combination of compound (i) and compound (ii) at ratios from 95:5 to 25:75 allows the composition to dynamically adapt its viscosity and fluidity characteristics, transitioning between more solidified and more fluid states while maintaining stabilization.
