Solution Overview

Problem

Existing cosmetic treatments fail to effectively utilize the beneficial effects of daphnane diterpenoids from the Daphne genus, particularly in stimulating the lymphatic system for skin care, leading to a need for new applications and improved preparations.

Innovation Solution

The use of plant extracts from Daphne species, such as Daphne giraldii and Daphne gnidium, containing daphnetoxin, which stimulate the lymphatic system, are incorporated into cosmetic preparations to enhance skin treatment, including anti-aging, detoxification, and lymphatic vascular function.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing cosmetic treatments are used, then skin protection is provided, but the lymphatic system is not stimulated and anti-aging effects are insufficient

Engineering Contradiction:
Improveskin protectionVSAvoidlymphatic system stimulation
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent combines multiple functional ingredients (Daphne extracts containing daphnetoxin, hyaluronic acid, and other cosmetic additives) into a single cosmetic composition that simultaneously provides skin protection, stimulates the lymphatic system, and delivers anti-aging effects. This merging of functions resolves the contradiction by integrating previously separate benefits into one unified treatment formulation.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The cosmetic preparation is designed to perform multiple functions: protecting the skin barrier, stimulating lymphatic vessel formation and function, reducing puffiness, and providing anti-aging benefits. The Daphne extract serves as a multi-functional active ingredient that addresses several skin concerns simultaneously, making the formulation universally applicable to various skin types and concerns.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If Daphne extracts are used to stimulate the lymphatic system, then anti-aging and detoxification effects are improved, but the complexity of the cosmetic formulation increases

Engineering Contradiction:
Improveanti-aging and detoxification effectsVSAvoidcosmetic formulation complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent optimizes the concentration and formulation parameters of Daphne extracts to achieve the desired lymphatic stimulation and anti-aging effects while maintaining cosmetic acceptability. By carefully controlling the amount of active ingredients and their delivery system, the formulation achieves enhanced functionality without excessive complexity in its composition or application.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If purified Daphne compounds are used, then the efficacy for lymphatic stimulation is enhanced, but the manufacturing complexity and cost increase

Engineering Contradiction:
Improvelymphatic stimulation efficacyVSAvoidmanufacturing complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent extracts and isolates the active Daphne compounds (particularly daphnetoxin) from the plant material and incorporates them into the cosmetic formulation. This extraction process concentrates the active ingredients to enhance lymphatic stimulation efficacy while allowing for controlled manufacturing. The extracted compounds can be incorporated in standardized forms that balance purity with manufacturing feasibility.

Inventive Principle:
Principle #2Taking out (Extraction)
