Heated Eyelash Applicator Tip for Fluid Mascara Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eyelash lengthening technologies face challenges in effectively orienting and controlling the placement of fibers at the ends of eyelashes, leading to moderate elongation gains and difficulty in application, particularly with mascara compositions that require heat to exhibit stringy characteristics.
Innovation Solution
A heating support assembly with an applicator tip that softens or becomes fluid when heated, allowing for easier application of mascara compositions that lengthen eyelashes, featuring a shape adapted for mounting on the heating support and facilitating even distribution around the eyelashes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a mascara composition with stringy character at room temperature is used to lengthen eyelashes, then eyelash lengthening effect is improved, but the composition becomes difficult to apply and control
Solution Approach 1:
The patent changes the temperature parameter of the mascara composition from room temperature to heated temperature (40-50°C). At heated temperature, the composition exhibits stringy character and fluidity that enables controlled application, while maintaining the ability to form long threads for eyelash lengthening. This resolves the contradiction by making the composition easy to apply when hot, then allowing it to set and maintain shape after application.
Solution Approach 2:
The patent employs periodic temperature variation: the composition is heated before application to achieve stringy character and fluidity for easy application, then allowed to cool after application to set the formed threads. This periodic heating and cooling cycle enables both easy application and effective lengthening without the control problems associated with room-temperature stringy compositions.
2Length of moving object
If a mascara composition with non-zero magnetic susceptibility is used with magnetic field to lengthen eyelashes, then eyelash lengthening effect is improved, but the device complexity increases
Solution Approach 1:
The patent replaces the magnetic field system with a thermal system. Instead of using magnetic fields to manipulate composition and achieve lengthening, the invention uses controlled heating to modify the composition's physical properties (stringy character, fluidity) enabling natural thread formation and attachment to eyelashes. This substitution eliminates the need for complex magnetic field generation equipment while achieving the same lengthening effect.
3Ease of operation
If complex heating application devices are used to apply hot mascara composition, then application of temperature-sensitive compositions is improved, but the device complexity increases
Solution Approach 1:
The patent segments the heating function from the application device. The mascara composition itself contains the heating capability through thermoplastic beads or particles that can be heated externally and then transfer heat to the composition. This segmentation allows a simple applicator device to work with temperature-sensitive compositions without requiring complex integrated heating mechanisms.
Solution Approach 2:
The patent introduces thermoplastic beads or particles as an intermediary between the external heat source and the mascara composition. These beads absorb heat from a simple heater, become fluid, and then transfer this thermal energy to the surrounding composition, enabling controlled heating and application without requiring the entire device to be complex.
