Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing wound dressings do not effectively promote the growth of epidermal basal layer stem cells, which are crucial for skin wound healing, due to hindrances from exudates and microorganisms at the wound site.

Innovation Solution

A wound dressing composition comprising 60 to 70 wt% glycerin, 28 to 39 wt% honey, 0.2 to 3.0 wt% fucoidan, and 0.2 to 3.0 wt% olive leaf extract, with 0.1 to 0.3 wt% xanthan gum, which provides osmotic drainage, antimicrobial effects, and viscosity control to support basal layer stem cell growth.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional wound dressings are used, then basic wound coverage is provided, but stem cell growth is hindered due to exudates and microorganisms at the wound site

Engineering Contradiction:

Improvestem cell growth promotionVSAvoidexudates and microorganisms

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent converts the harmful effects of exudates and microorganisms into beneficial outcomes by using fucoidan to transform exudate drainage into a controlled process that removes harmful substances while preserving stem cells, and by utilizing olive leaf extract to convert microbial presence into an opportunity for antimicrobial action that protects the wound environment

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The patent introduces fucoidan and olive leaf extract as intermediary substances that mediate between the harmful wound environment and the stem cells. These intermediaries drain exudates, kill microorganisms, and create a protected environment that allows stem cells to proliferate without direct exposure to harmful factors

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If fucoidan and olive leaf extract are added to promote stem cell growth, then wound healing is enhanced, but the composition complexity increases

Engineering Contradiction:

Improvewound healing rateVSAvoidcomposition complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent creates a composite wound dressing composition by combining fucoidan, olive leaf extract, and standard wound dressing ingredients in specific ratios. This composite approach integrates multiple functional components (stem cell promotion, exudate drainage, antimicrobial action) into a single unified formulation that enhances wound healing without excessive complexity

Inventive Principle:

Principle #40Composite materials

3Reliability

If high concentrations of active ingredients are used to maximize stem cell proliferation, then healing effectiveness increases, but cytotoxicity and irritation risks increase

Engineering Contradiction:

Improvestem cell proliferationVSAvoidcytotoxicity and irritation

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent optimizes the concentration parameters of fucoidan (0.1-5.0 wt%) and olive leaf extract (0.1-5.0 wt%) to achieve the highest possible stem cell proliferation while staying below cytotoxic thresholds. This parameter optimization allows maximum therapeutic effect without excessive harm

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent uses fucoidan and olive leaf extract as intermediary substances that mediate between the desired high stem cell proliferation and the risk of cytotoxicity. These intermediaries provide protective effects that allow higher concentrations to be used safely by reducing direct toxic effects on surrounding tissues

Inventive Principle:

Principle #24Intermediary (Mediator)
