Solution Overview

Problem

Existing oils and fats with high n-decanoic acid content cause discomfort such as pharynx irritation and stomach heaviness, and suffer from poor cold resistance, especially in refrigerated emulsified foods.

Innovation Solution

Formulations with 65-95% medium chain fatty acids, 60-75% n-decanoic acid, and 3-35% unsaturated fatty acids, combined with long chain fatty acids, maintain clarity and stability at low temperatures, minimizing discomfort and demulsification.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If MCTs with high n-decanoic acid content are used, then discomfort such as pharynx irritation and stomach heaviness is reduced, but oil and fat crystals are likely to be deposited at temperatures around 0 to 5°C

Engineering Contradiction:
Improvepharynx irritation and stomach heavinessVSAvoidcold resistance
Core Design Contradiction:
Object-affected harmful factorsVSStability of the object's composition

Solution Approach 1:

The patent changes the compositional parameters of the oil by specifying precise ranges: medium chain fatty acids (6-10 carbons) at 65-95% total fatty acids, n-decanoic acid at 50-70% of medium chain fatty acids, and unsaturated fatty acids at 3-35% total fatty acids. This parameter optimization resolves the contradiction by achieving both reduced discomfort and improved cold resistance.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite fatty acid composition that combines multiple types of fatty acids (saturated medium chain, unsaturated, and n-decanoic acid) in specific proportions. This composite approach allows the oil to benefit from the low irritation properties of n-decanoic acid while the unsaturated fatty acids contribute to cold resistance by preventing crystal deposition.

Principle #40Composite materials

2Use of energy by moving object

If large amounts of medium chain fatty acid triglycerides are ingested at one time, then energy intake efficiency is improved, but discomfort such as irritation of the pharynx or upper stomach and heavy feelings in the stomach are caused

Engineering Contradiction:
Improveenergy intake efficiencyVSAvoidpharynx irritation and stomach heaviness
Core Design Contradiction:
Use of energy by moving objectVSObject-affected harmful factors

Solution Approach 1:

The patent optimizes the fatty acid composition parameters to contain n-decanoic acid at 50-70% of medium chain fatty acids, which specifically reduces pharynx irritation and stomach heaviness while maintaining rapid energy conversion properties. This allows high-energy intake without the harmful discomfort effects.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If emulsified foods are kept refrigerated, then food safety is improved, but the ease of use is poor due to crystal deposition

Engineering Contradiction:
Improvefood safetyVSAvoidease of use
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent modifies the oil composition parameters by including unsaturated fatty acids at 3-35% of total fatty acids, which lowers the freezing point and prevents crystal deposition at refrigeration temperatures (0-5°C). This allows emulsified foods to remain safe when refrigerated while maintaining good ease of use without crystallization issues.
