Solution Overview

Problem

Current eyeshadow makeup accessories fail to effectively protect eyelashes and eyes from makeup contamination during application, leading to irritation, infections, and damage, and are often cumbersome or inefficient.

Innovation Solution

An eyelash protector makeup accessory with an elongated handle and curved shield design, featuring a shield portion with ergonomic angles and rounded corners, and a handle with a gripping element and versatile coupling structures, which can be attached to either side to accommodate different user preferences, providing a seamless and protective makeup application experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If traditional eyeshadow makeup accessories are used, then makeup application can be performed, but eyelashes and eyes are not protected from makeup contamination

Engineering Contradiction:

Improvemakeup contamination to eyelashes and eyesVSAvoidmakeup application process

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patent introduces a protective barrier (shield or tape) as an intermediary element between the makeup application area and the eyelashes/eyes. This barrier physically blocks makeup particles from contaminating the eyes and eyelashes while allowing the makeup application process to continue normally. The shield acts as a mediator that separates the harmful factor (makeup residue) from the vulnerable target (eyes and eyelashes).

Inventive Principle:

Principle #24Intermediary (Mediator)

2Strength

If makeup is applied without protection, then the application process is simple, but eyelashes suffer from makeup buildup leading to breakage or loss

Engineering Contradiction:

Improveeyelash integrityVSAvoidtime to remove makeup

Core Design Contradiction:

StrengthVSLoss of time

Solution Approach 1:

The patent applies protective measures (shield or tape) before the makeup application process begins. This preliminary action prevents makeup from contacting the eyelashes in the first place, rather than requiring removal afterward. By establishing protection beforehand, the patent eliminates the need for time-consuming makeup removal and prevents eyelash damage entirely.

Inventive Principle:

Principle #10Preliminary action

3Object-affected harmful factors

If existing protective devices are used, then some protection is provided, but they are cumbersome and do not fully address user needs

Engineering Contradiction:

Improveeye and eyelash contaminationVSAvoidprotective device structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent divides the protective function into separate, simple components: a shield portion and an optional handle portion that can be removably coupled. This segmentation allows the device to be simple when only the shield is needed, while offering optional handle attachment for users who need extended reach or different handling. The modular design reduces overall complexity while maintaining protective effectiveness.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The shield portion is designed to be universally applicable with optional handle attachments that can be coupled to either side, accommodating different user preferences and application styles. The same basic shield structure serves multiple functions: direct use for simple protection, or with handle attachment for extended reach or different handling comfort. This universality reduces the need for multiple different protective devices.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Measurement precision

If precision application tools are used, then makeup application precision is improved, but protection of eyelashes from contamination is not adequate

Engineering Contradiction:

Improvemakeup application precisionVSAvoidmakeup residue on eyelashes

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent merges two previously separate functions into a single integrated device: the precision makeup application function and the eye/eyelash protection function. By combining the applicator or shield with the protective barrier, the patent enables users to achieve both precise makeup application and adequate protection simultaneously, rather than having to choose between precision tools that lack protection or protective devices that compromise precision.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

An eyelash protector makeup accessory is provided which utilizes a shield portion having a first side surface opposite a second side surface and a third side surface opposite a fourth side surface. A first coupling structure is disposed adjacent a first peripheral edge of the first side surface. The first side surface comprises a first convex shape having a first radius of curvature value. The third side surface utilizes a first concave shape having a second radius of curvature value. The accessory further utilizes an elongate handle portion having an elongate shaft. The elongate shaft utilizes a gripping element disposed at a proximal end thereof and a second coupling structure disposed at a distal end thereof. The second coupling structure is shaped in a complimentary manner relative the first coupling structure and the second coupling structure removably engages the first coupling structure.
