Solution Overview

Problem

Skin is exposed to harmful components of air pollution, such as particulate matter (PM), leading to oxidative stress and damage through the generation of reactive oxygen species (ROS).

Innovation Solution

Personal care compositions incorporating a synergistic combination of flaxseed oil and hempseed oil, or flaxseed oil with a vitamin B compound like niacinamide, in specific ratios, to reduce ROS levels in the skin.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional personal care products are used, then basic skin care functions are provided, but they fail to effectively reduce ROS levels and protect against oxidative stress from pollution

Engineering Contradiction:
Improveskin protection efficacyVSAvoidROS levels
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent combines multiple plant oils (flaxseed oil, hempseed oil, rosehip oil) with specific vitamin B compounds (niacinamide, pyridoxine, cyanocobalamin) in defined ratios to create a composite composition that synergistically reduces ROS levels. This composite approach provides superior skin protection compared to conventional single-ingredient products, directly addressing the insufficient efficacy of traditional personal care products against pollution-induced oxidative stress

Inventive Principle:
Principle #40Composite materials

2Reliability

If higher concentrations of active ingredients are used, then ROS reduction efficacy is improved, but the risk of skin irritation and adverse reactions increases

Engineering Contradiction:
ImproveROS reduction efficacyVSAvoidskin irritation risk
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent specifies precise concentration ranges for each ingredient (plant oils at 0.1-10%, vitamin B compounds at 0.01-5%) and their ratios to each other. This parameter optimization ensures sufficient ROS reduction efficacy while maintaining skin compatibility and minimizing irritation risk, resolving the contradiction between effectiveness and safety

Inventive Principle:
Principle #35Parameter changes

3Reliability

If multiple ingredients are combined to enhance ROS reduction, then protection efficacy is improved, but the formulation complexity and manufacturing difficulty increase

Engineering Contradiction:
Improveprotection efficacyVSAvoidformulation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent divides the complex formulation into distinct functional modules: a plant oil phase (flaxseed oil, hempseed oil, rosehip oil) and a vitamin B compound phase (niacinamide, pyridoxine, cyanocobalamin). This segmentation allows for systematic formulation development and quality control while maintaining the synergistic benefits of multiple ingredients, managing complexity through structured organization

Inventive Principle:
Principle #1Segmentation
