Solution Overview

Problem

Existing methods for modifying the appearance of the eye, such as makeup and adhesive strips, are ineffective in addressing asymmetry, drooping eyelids, and age-related changes, as they are either temporary, uncomfortable, or unsuitable for all eye types.

Innovation Solution

A patch with a non-plane shape featuring multi-directional curvature is applied to the upper eyelid, allowing it to conform to the eyelid's shape and maintain that shape through plastic deformation, providing comfort and adaptability while potentially eliminating the need for adhesives.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If makeup compositions are applied to the eye outline, then the eyes are emphasized in color, but the shape of the eye outlines is not affected and the effect is temporary

Engineering Contradiction:
Improveeye outline shapeVSAvoidmakeup duration
Core Design Contradiction:
ShapeVSDuration of action of moving object

Solution Approach 1:

The patch is designed with a curved surface that conforms to the three-dimensional topology of the eyelid, allowing it to effectively modify the eye outline shape by lifting the upper eyelid and correcting drooping, while providing long-lasting effect throughout the day

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Shape

If adhesive strips are applied to the movable upper eyelid, then drooping of the stationary upper eyelid is corrected, but the strip is not adapted to the topology of the eyelid resulting in discomfort

Engineering Contradiction:
Improveeyelid shapeVSAvoidcomfort
Core Design Contradiction:
ShapeVSEase of operation

Solution Approach 1:

The patch features a curved surface design that adapts to the three-dimensional topology of the eyelid, providing comfort while effectively correcting drooping and modifying eye shape

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The patch incorporates varying thickness parameters across its surface, with greater thickness in central zones for lifting support and reduced thickness at edges for comfort and adaptability to eyelid contours

Inventive Principle:
Principle #35Parameter changes

3Shape

If flat adhesive strips are used to correct drooping, then the stationary upper eyelid is lifted, but the solution is not effective for all eye types including Asiatic, Caucasian, or African eyes

Engineering Contradiction:
Improveeye outline shapeVSAvoidadaptability to different eye types
Core Design Contradiction:
ShapeVSAdaptability or versatility

Solution Approach 1:

The patch is designed as a universal cosmetic device that can be applied to various eye types (Asiatic, Caucasian, African) and effectively modifies eye outline shape, corrects drooping, and adapts to different eyelid topologies through its curved surface design

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

Solution Approach 2:

The patch features zones with different thickness characteristics - a central zone with greater thickness for lifting support and peripheral zones with reduced thickness for comfort - allowing it to effectively address different eye types and anatomical variations

Inventive Principle:
Principle #3Local quality

4Shape

If plastic surgery is performed to modify eye appearance, then major corrective purposes are achieved, but the procedure is radical, painful, and does not achieve a more youthful look

Engineering Contradiction:
Improveeye outline shapeVSAvoidpain and invasiveness
Core Design Contradiction:
ShapeVSObject-affected harmful factors

Solution Approach 1:

The patch provides a non-invasive, painless, and reversible alternative to plastic surgery for correcting drooping and modifying eye appearance, offering a youthful look without the harmful effects of surgical intervention

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The patch effectively modifies the eye's appearance by lifting the stationary eyelid, reducing asymmetry, and adapting to various eye types, offering a long-lasting, comfortable, and reversible solution.

Implementation Method 1

made of a material suitable for responding to stress by deforming in non-elastic manner as to take up multi-directional curvature on the eyelid and conserve said curvature when the stress ceases

Methodology Applied
Scientific EffectPlastic deformation: Plasticity

AI summary

The present invention provides a method of cosmetically modifying the appearance of the outline of the eye, the method comprising the step consisting in applying at least one patch (1) on the movable upper eyelid, the application face (Ia) of the patch (1) having a predefined non-plane shape with multi-directional curvature, or at least one patch made of a material suitable for responding to stress by deforming in non- elastic manner as to take up multi-directional curvature on the eyelid and conserve said curvature when the stress ceases.
