Solution Overview

Problem

Existing methods for applying volume eyelash extensions often result in uneven distribution and inconsistent opening angles due to operator error, leading to a messy appearance and inefficiency in application time and material usage.

Innovation Solution

A method utilizing an eyelash extensions applying auxiliary with reference lines to align and adhere eyelash extensions consistently, ensuring uniform opening angles by using tweezers to position and adhere the extensions onto natural lashes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If conventional manual method is used to apply volume eyelash extensions, then the application process is simple, but the opening angles become inconsistent and distribution becomes uneven

Engineering Contradiction:
Improveopening angle consistencyVSAvoidapplication process complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent introduces an auxiliary tool as an intermediary device between the operator and the eyelash extensions. This tool includes a support surface with reference lines that guide the alignment and fanning of multiple eyelash extensions, ensuring consistent opening angles without requiring complex manual dexterity from the operator.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The auxiliary tool is prepared in advance with pre-drawn reference lines and marking positions. These preliminary markings establish the correct spacing and angle distribution before the actual application process begins, allowing the operator to simply follow the pre-established guide rather than calculating angles during application.

Inventive Principle:
Principle #10Preliminary action

2Loss of substance

If conventional manual method is used to apply eyelash extensions, then the process is quick, but the material waste increases

Engineering Contradiction:
Improveeyelash extension wasteVSAvoidapplication speed
Core Design Contradiction:
Loss of substanceVSProductivity

Solution Approach 1:

The auxiliary tool allows the operator to pre-arrange and fan the eyelash extensions in the correct configuration before applying adhesive. This preliminary positioning ensures that only the necessary number of extensions are prepared and applied, reducing material waste while maintaining efficient application speed through the pre-established guide.

Inventive Principle:
Principle #10Preliminary action

3Manufacturing precision

If multiple eyelash extensions are applied to one natural eyelash, then the volume effect is achieved, but the distribution becomes uneven

Engineering Contradiction:
Improvedistribution uniformityVSAvoidalignment difficulty
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The auxiliary tool serves as a mediator that physically supports and positions multiple eyelash extensions during the fanning process. The reference lines on the support surface provide visual and physical guides that ensure even distribution of extensions, making the alignment process straightforward despite the complexity of handling multiple extensions simultaneously.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A method for applying eyelash extensions includes: transporting an eyelash extension bundle to an eyelash extensions applying auxiliary, the eyelash extensions each having an attaching end, a root and a distal end, the eyelash extensions applying auxiliary having an attaching reference point, a first reference line and a second reference line, the first and second reference lines or imaginary extension lines thereof being joined at the attaching reference point; the attaching ends of the eyelash extensions being located right at the attaching reference point after the transportation; aligning two of the eyelash extensions in the eyelash extension bundle with the first and second reference lines, respectively, with a pair of tweezers; coating the attaching ends of the eyelash extensions with adhesive, and adhering the attaching ends coated with the adhesive to a root of a human eyelash. Thereby, eyelash extension bundles can all have uniform open angles with enhanced applying quality.
