Solution Overview

Problem

Vitamin C, a widely used antioxidant, is prone to oxidation due to its high reducing power and sensitivity to environmental factors, leading to rapid degradation and loss of effectiveness in cosmetics, nutritional supplements, and food products, which limits their storage period and efficacy.

Innovation Solution

A method using nucleotide aptamers to inhibit the oxidation of vitamin C by binding to its lactone ring, forming an aptamer-vitamin C complex that is incorporated into hydrogels, allowing controlled release and maintaining the reduced state of vitamin C, thereby extending its antioxidant function.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If vitamin C is used as an antioxidant in cosmetics and nutritional supplements, then antioxidant activity is improved, but oxidation stability deteriorates

Engineering Contradiction:
Improveantioxidant activityVSAvoidoxidation stability
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent introduces aptamers as intermediary molecules that bind to vitamin C through specific recognition of the lactone ring structure. This aptamer-vitamin C complex acts as a mediator that protects vitamin C from direct oxidation while maintaining its antioxidant function, resolving the contradiction between antioxidant activity and oxidation stability

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates a composite system consisting of aptamers and vitamin C molecules. This composite material combines the stabilizing properties of aptamers with the antioxidant properties of vitamin C, achieving both oxidation stability and antioxidant activity simultaneously

Inventive Principle:
Principle #40Composite materials

2Reliability

If vitamin C is applied to skin for antioxidant protection, then skin aging prevention is improved, but storage period deteriorates

Engineering Contradiction:
Improveskin protection efficacyVSAvoidstorage period
Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The patent applies preliminary protection by pre-binding vitamin C to aptamers before application to the skin. This preliminary complex formation protects vitamin C from oxidation during storage and transport, ensuring the product remains effective throughout its shelf life while maintaining skin protection capabilities

Inventive Principle:
Principle #10Preliminary action

3Productivity

If vitamin C is used in high concentration for maximum antioxidant effect, then antioxidant efficiency is improved, but oxidation rate deteriorates

Engineering Contradiction:
Improveantioxidant efficiencyVSAvoidoxidation rate
Core Design Contradiction:
ProductivityVSSpeed

Solution Approach 1:

The patent uses aptamers as protective intermediaries that bind to vitamin C molecules. This allows the use of high vitamin C concentrations for maximum antioxidant effect while the aptamers prevent rapid oxidation, thus maintaining both antioxidant efficiency and slowing oxidation rate

Inventive Principle:
Principle #24Intermediary (Mediator)
