Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

There is a need for a composition that can form a protective, occlusive layer while delivering moisturizing emollients to combat eyelid skin discomfort and irritation, which is mild enough for application in the ocular region, as existing moisturizers often contain harsh ingredients unsuitable for the sensitive skin around the eyes.

Innovation Solution

A topical ointment comprising a dermatologically acceptable vehicle with a lipid mixture including sphingolipids, oils, and hydrophilic solvents, formulated to create a protective, occlusive layer that moisturizes and reduces inflammation without stinging or irritation, using ingredients like phytosphingosine, castor oil, and white petrolatum.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If hydrocortisone cream is used to treat irritation of the skin, then the skin irritation is reduced, but the composition becomes too harsh for use on the eyelid or in the ocular region

Engineering Contradiction:

Improveskin irritationVSAvoidsuitability for ocular region application

Core Design Contradiction:

Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The patent creates a specialized formulation with locally optimized properties for the ocular region. The composition uses mild ingredients specifically selected for delicate skin, including petrolatum, mineral oil, and plant-derived emollients, while excluding harsh components like hydrocortisone. This local quality approach allows the product to be specifically adapted for the sensitive eyelid area rather than using a general-purpose harsher treatment.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent extracts and removes harmful ingredients from the formulation. By explicitly excluding hydrocortisone and other harsh steroids from the composition, the invention creates a safe formulation for ocular region use while still providing effective moisturization and irritation relief through milder alternative ingredients.

Inventive Principle:

Principle #2Taking out (Extraction)

2Reliability

If a protective occlusive layer is formed to combat dryness, then moisture retention is improved, but the composition may become too heavy or occlusive for the delicate eyelid skin

Engineering Contradiction:

Improvemoisture retentionVSAvoidskin burden from heavy occlusion

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent employs a composite formulation combining multiple lightweight occlusive and emollient ingredients. The composition integrates petrolatum (5-20%), mineral oil (5-20%), and various plant-derived emollients (coconut oil, almond oil, jojoba oil, etc.) in specific proportions. This composite approach provides effective moisture retention through multiple synergistic components while maintaining a lightweight, non-burdensome texture suitable for delicate eyelid skin.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The patent optimizes the concentration parameters of occlusive ingredients to achieve the right balance between protection and comfort. By limiting petrolatum to 5-20% and mineral oil to 5-20%, and incorporating multiple lighter emollients, the formulation provides sufficient occlusion for moisture retention while avoiding the heavy, suffocating feel that would burden delicate eyelid skin.

Inventive Principle:

Principle #35Parameter changes

3Speed

If quick-acting soothing ingredients are used to relieve discomfort, then the speed of relief is improved, but the ingredients may be too harsh for the sensitive ocular region

Engineering Contradiction:

Improvespeed of relief from discomfortVSAvoidmildness for ocular region application

Core Design Contradiction:

SpeedVSAdaptability or versatility

Solution Approach 1:

The patent utilizes ingredients that provide self-soothing benefits through their natural properties. The formulation includes plant-derived emollients (coconut oil, almond oil, jojoba oil, evening primrose oil, tea tree oil) and panthenol that naturally soothe, moisturize, and calm irritated skin without requiring harsh active ingredients. These ingredients work synergistically to provide quick relief while remaining gentle enough for the sensitive ocular region.

Inventive Principle:

Principle #25Self-service

AI summary

A composition for treating dry skin includes therapeutically active concentrations of one or more skin protecting lipids in an oleaginous base. The skin protecting lipids can include a sphingolipid and at least one oil. The composition is intended for application on the skin surrounding the eyes. The composition is configured to form a protective, occlusive layer that can moisturize the skin and reduce inflammation and itching without stinging, burning, or stripping the skin. According to an exemplary embodiment, the composition is formulated as a high viscosity ointment or gel.
