Solution Overview

Problem

Existing eyelid cleansers are not suitable for sensitive ocular areas, often harsh and unsuitable for managing eyelid health, leading to poor compliance and ineffective treatment of conditions like blepharitis and chalazion.

Innovation Solution

A medicated eyelid cleansing composition containing therapeutically effective amounts of antibacterial and anti-inflammatory agents, such as azithromycin, diclofenac sodium, or dexamethasone phosphate, formulated with pH adjustment to 6 to 7.5, suitable for gentle use around the eyes, and combined with eyelid cleansing compositions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If ordinary skin cleansers are used for eyelid cleaning, then mechanical cleansing and debris removal are achieved, but the composition is harsh on the thin skin in the ocular area and may cause irritation

Engineering Contradiction:
Improvecleansing effectivenessVSAvoidirritation to ocular skin
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The patent adjusts the pH of the eyelid cleanser composition to be within the physiological range (pH 5.5-7.5), which is gentler on the delicate ocular skin compared to conventional cleansers. This parameter change maintains cleansing effectiveness while reducing irritation to the thin eyelid skin.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The invention formulates a specialized composition with mild surfactants and soothing ingredients specifically tailored for the delicate ocular area, rather than using generic skin cleansers. This localized formulation addresses the unique sensitivity of eyelid skin while maintaining effective cleansing.

Inventive Principle:
Principle #3Local quality

2Reliability

If existing skin ointments are used for eyelid treatment, then therapeutic effects are provided, but the thick and heavy texture makes them challenging to use around the eyes and may not permit flexible use during the day

Engineering Contradiction:
Improvetherapeutic effectVSAvoidusability around eyes
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent transforms the physical state and texture of the therapeutic composition from thick and heavy to a lighter, more flexible formulation that is easy to apply around the eyes. This parameter change maintains therapeutic effectiveness while significantly improving ease of use and patient compliance.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The invention combines cleansing and therapeutic functions in a single lightweight composition that can be used flexibly throughout the day, unlike traditional ointments that are either too heavy for daytime use or require separate application steps. This multi-functional approach improves both usability and treatment consistency.

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

3Ease of manufacture

If conventional cleanser compositions are used, then general cleaning is achieved, but they lack therapeutic amounts of antibacterial and anti-inflammatory medication needed for eyelid conditions

Engineering Contradiction:
Improvecleaning functionVSAvoidtherapeutic effectiveness
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent merges cleansing ingredients with therapeutic amounts of antibacterial and anti-inflammatory medications into a single integrated composition. This combination allows the product to simultaneously perform mechanical cleansing and provide pharmacological treatment for eyelid conditions like blepharitis, addressing both cleaning and therapeutic needs in one application.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The invention creates a composite formulation that integrates mild surfactants, soothing agents, and therapeutic medications into a unified composition specifically designed for eyelid application. This composite material approach ensures both gentle cleansing and effective treatment without the harshness of conventional cleansers.

Inventive Principle:
Principle #40Composite materials
